Evaluation Disclaimer:
Firstly I wish to thank Burger Motorsports for agreeing to sponsor me for this assessment. Regardless of this I’ll stay as unbiased as doable throughout the assessment. Please word, the dynamics of this relationship was that I reached out for a sponsorship assessment and never the opposite approach round. This could show how I actually really feel concerning the BMS F collection N55 Race Core Intercooler – within the sense that I actually consider it is among the finest if not the best possible race core intercooler accessible for the F collection N55. In actual fact I even have this BMS F collection N55 Race Core Intercooler put in by myself m2 as of now, and I actually like the standard, fin density, fitment, and immense IAT suppression it has.
Buyer Service and Transport:
Firstly I wish to begin this assessment off with a fast dialogue relating to the customer support and delivery expertise that I had when reviewing the BMS race core intercooler.
As per typical BMS customer support is completely high notch, you’ll all the time get involved with a human and more often than not inside minutes of your e mail – like it’s astonishing how briskly they reply, I actually simply put down my cellphone and I immediately get an e mail again. Props to BMS on this from they’re extraordinarily good at reply instances, like I can’t commend them sufficient for a way amazingly good their response price is, even on weekends too 1000/10 BMS. (In contrast to one other intercooler firm who by no means received again to me ever, simply an auto reply from their e mail server and that was it).
However quick reply instances aren’t any good if the client help is just not educated or impolite. Effectively I need to inform you BMS customer support is insanely educated and insanely affected person, irrespective of what number of questions have been requested they may all the time reply promptly and by no means trace that they’re getting annoyed with you.
Lastly I wish to speak about their stage of buyer care when issues do go mistaken, as a result of replying promptly, being very type and courteous, and being educated means completely nothing in the event that they dont maintain you when issues go mistaken. So in my case I truly acquired a faulty intercooler – with points on the internals of the intercooler which made me really feel uncomfortable with utilizing it. Upon recognizing this difficulty I despatched BMS an e mail, and so they promptly started investigating this difficulty. This investigation consisted of contacting the producer to determine the reason for the problem, and even finding one other faulty unit and testing it regionally with tremendous circulation (a really respected air circulation testing firm) to additional be taught extra about this difficulty. On the finish of the investigation it was decided that the problem was beauty in nature and didn’t hinder efficiency, nonetheless BMS addressed this difficulty with the producer to mitigate the problem in future batches of intercoolers and so they even changed my intercooler freed from cost – and this all occurred in a really quick and well timed method. Total, the expertise with BMS was wonderful, they addressed my difficulty severely, changed my product freed from cost, and cared sufficient to be taught extra about the issue to handle it correctly and enhance their product for the longer term – and guarantee nobody else runs into this difficulty.
So as soon as once more 10/10 BMS your customer support is impeccable and needs to be the benchmark of bmw components distributors.
How Do Air to Air Intercoolers Work:
Now I wish to start this assessment with a short clarification of how air to air intercoolers work, for these which can be new to this subject, should you already know all the pieces there may be to know then be at liberty to skip onto the subsequent part.
Credit score: ECS Tuning modified by F87Source https://www.ecstuning.com/b-genuine-…r/17517600531/
So the best way an intercooler works is it takes scorching compressed air from the turbocharger in by means of the inlet aspect and makes an attempt to evenly unfold it throughout the entire bar and plates or tube and fins (these are little channels within the intercooler that carry air throughout the intercooler core) within the intercooler, the place the air is ducted by means of to the outlet aspect of the intercooler. Throughout this ducting course of the recent air will circulation by means of the metallic tube or bar and plate and switch its warmth into the metallic itself. The recent metallic tube/bar and plate will then switch the warmth to the fins (little items of metallic brazed onto the tubes or bar and plates, and their job is to dissipate warmth into the ambient air) which is able to dissipate the warmth into the air that flows by means of the intercooler core. Then when the air reaches the outlet aspect of the intercooler it would have cooled down and is able to enter the engine.
Bar and Plate VS: Tube and Fin:
Credit score: ShopDap https://www.shopdap.com/weblog/put up/wh…tercooler.html
So what are the variations between Tube and Fin and Bar and Plate intercoolers? Effectively bar and plate intercoolers use thick metallic bars and plates to type the air carrying channel, these bars and plates are then brazed to the fins to conduct and dissipate warmth. Tube and fin intercoolers use hole metallic tubes to hold the air, and these tubes are once more brazed to fins.
Now lets discuss concerning the options of every design:
Bar and Plate:
a) Larger thermal mass: bar and plate type oil intercooler channels use much more metallic to assemble them. This implies they’ve a number of thermal mass and subsequently it takes extra warmth to heat it up each 1C. So if you’re doing a number of low pace driving (auto x) that doesnt enable a number of air to cross by means of the intercooler, these bar and plate intercoolers are the best way to go as it would purchase you extra time earlier than the air can warmth up (because of the excessive thermal mass).
b) Sturdiness: due to the heavy responsibility building of those bar and plate channels and because of the quantity of metallic used to make them, they’re very robust and resilient to impacts from stones on the street. That is preferrred for intercoolers as a result of it prevents them from being punctured and inflicting increase leaks.
For example check out this tube and fin distant/aux radiator (Im utilizing a radiator for instance as a result of it’s simpler to visualise the leaking coolant vs. leaking air):
Credit score: Jake335i https://xoutpost.com/bmw-sav-forums/…placement.html
You’ll be able to see the tube was broken attributable to a rock affect and this prompted it to leak coolant, and this is quite common on distant/aux radiators in addition to intercoolers should you search on-line (and that is possible because of the weaker and extra susceptible tube and fin design).
Tube and Fin:
a) Fast heating and cooling: attributable to their low thermal mass they cool and warmth up in a short time. It is a con as a result of they endure from warmth soak extra simply, however it is usually a profit as a result of they recuperate from warmth soaking a lot faster. So it is a double edged sword.
b) mild weight: these intercoolers are usually very mild because of the skinny tube design.
In abstract I personally choose bar and plate type intercoolers as a result of I need the sturdiness, since there may be all the time a number of gravel on the roads right here in Canada after winter. Plus it’s good to have a extra sturdy core for observe utilization, the place particles could be flung on the intercooler.
Inventory F Sequence N55 Intercooler:
Subsequent I wish to rapidly go over the inventory intercooler that comes with these F collection n55 automobiles.
Credit score: ECS Tuning https://www.ecstuning.com/b-genuine-…r/17517600531/

Credit score: ECS Tuning https://www.ecstuning.com/b-genuine-…r/17517600531/
1) Tube and Fin: the inventory intercooler makes use of a tube and fin design, this leads to:
– Low weight: the inventory intercooler is within the ~9lbs weight vary and is extraordinarily mild. This makes set up and removing very straightforward, and provides very low mass to the entrance of the automotive.
– Low thermal mass: The con of being so mild weight is that the inventory intercooler has a really low thermal mass and it warmth soaks and heats up very quickly. You’ll discover this should you log IATs as you will note consumption temperatures rise quickly as quickly as you begin driving the automotive laborious or begin sitting in site visitors.
– Fast cooling: The professional of being so mild weight is that the inventory intercooler will calm down in a short time when you begin cruising at regular speeds.
– Fragile: The tube and fin design will make these inventory intercoolers much less sturdy than a bar and plate intercooler, so will probably be extra prone to rock strikes.
2) Fins:
Credit score: F87Source
The fins on the inventory intercooler are louvered to extend floor space and subsequently enhance thermal change. Nonetheless, the problem with louvering the skinny aluminum fins is that it makes them very gentle and malleable, and this makes them very prone to bending and being crushed attributable to rock impacts.
Credit score: F87Source
The inventory intercooler additionally has a fin density of ~7 fins per cm.
3) Dimensions:
Credit score: F87Source
Credit score: F87Source
Credit score: F87Source
The inventory intercooler has the next dimensions (LXWXH): 49.5 cm X 10 cm X 14.5 cm, this implies it has a frontal floor space of: 495 cm^2 and it has a quantity of seven,177.5 cm^3.
4) Plastic finish tanks and connectors:
Credit score: ECS Tuning https://www.ecstuning.com/b-genuine-…r/17517600531/
The inventory intercooler has plastic finish tanks and plastic inlet/outlet connectors. Sometimes we dont see many failures from the plastic construct high quality of the inventory intercooler – however it could possibly probably fatigue and crack over time just like the plastic finish tanks and connectors on radiators do.
Abstract:
So in abstract I consider the inventory intercooler is woefully undersized to correctly management IATs for modified F collection n55s and even the inventory m2 which runs as a lot increase as a stage 2 F collection n55. The inventory intercooler can be fairly prone to damages from rock impacts because of the gentle fins from the in depth louvering, and it is vitally prone to warmth soak because of the low fin density and tube and fin design.
5 Stepped Core Intercoolers:
Subsequent I wish to go over a quite common intercooler improve for the F collection n55, and these are the standard 5 stepped core intercoolers just like the BMS 5 stepped core intercooler: https://burgertuning.com/collections…-f-chassis-bmw

1) Bar and Plate:
Credit score: F87Source
Credit score: F87Source
Credit score: F87Source
Sometimes these 5 stepped core intercoolers just like the BMS are bar and plate type intercoolers, there are exceptions just like the wagner intercooler which can be tube and fin – however most of them are bar and plate. This implies these intercoolers have the next traits:
– Excessive weight: Sadly because of the heavy responsibility bar and plate building, these intercoolers are sometimes fairly heavy – particularly when in comparison with inventory.
– Proof against warmth soak: These intercoolers are additionally very immune to warmth soak since they’ve a lot thermal mass, this implies they may have the ability to take extra heavy driving earlier than they begin to warmth soak. This is excellent for drag racing or auto x (very low air circulation more often than not because of the predominantly low pace driving, and thus you might want to have an intercooler that has sufficient thermal mass to maintain iats low), the place you wish to forestall warmth soaking as a lot as doable.
– Sturdiness: These bar and plate intercoolers are exceptionally sturdy attributable to their heavy responsibility building, so harm attributable to street particles needs to be very uncommon. I’ve truly run a BMS 5 stepped core intercooler for the final ~4 years and haven’t encountered any harm regardless of it being continuously bombarded with rocks and gravel from the winter.
2) Fins: The fin design varies drastically between intercooler to intercooler, so I’ll solely be discussing the BMS 5 stepped core intercooler since that is the intercooler that I truly personal and have a number of expertise with.
Credit score: F87Source
Credit score: F87Source
The BMS 5 stepped core intercooler makes use of stable un-louvered fins which can be very sq. in design. This leads to very stable and powerful fins which can be very immune to impacts. I’ve run the BMS intercooler for the final 3-4 years and there may be not a single dented fin on this intercooler which is spectacular. Now to extend floor space for improved thermal change BMS makes use of staggered and stack fins, the place there are 2 fins proper subsequent to one another, however they’re simply recessed a bit and staggered, it’s laborious to see in images however should you look carefully within the photographs above you may see them. The result’s ~8 fins/cm* (if you don’t depend the staggered fins which is difficult to see on this image – it seems to be a lot totally different in actual life, however with the staggered fins it’s within the ~14 fin/cm vary). So the BMS intercooler has a considerably increased fin density than the inventory intercooler.
3) Stepped Core:
Credit score: F87Source
Credit score: F87Source
The BMS intercooler makes use of a stepped core, which implies there’s a small raised part above the principle core permitting for a rise in frontal floor space and core quantity – which ought to drastically enhance cooling over the inventory intercooler.
4) Steel finish tanks and connectors:
The BMS 5 stepped core intercooler makes use of stable aluminum finish tanks and connectors for the inlet and outlet aspect, this implies the intercooler is exceptionally sturdy and will by no means have points with cracking or materials fatigue.
5) Dimensions:
Credit score: F87Source
Credit score: F87Source
Credit score: F87Source
Credit score: F87Source
The BMS 5 stepped core intercooler has the next dimensions (LXWXH essential core, LXWXH step): 51 cm X 12 cm X 15 cm, 51 cm X 4 cm X 6.5 cm.
The BMS intercooler can be 2 cm vast than inventory which will increase the quantity of the intercooler permitting for a better thermal capability earlier than warmth soaking, the bms intercoolers essential core part has the identical peak because the inventory intercooler, but it surely does embody a step including and additional 331.5 cm2 of floor space and 1,326 cm3 of quantity which is able to aide in cooling.
Abstract:
So general it is a improbable improve for these on the lookout for a bit of additional enchancment over the inventory intercooler, or are attempting to optimize air circulation to the radiator (since it isn’t so tall that it blocks a ton of air circulation to the radiator like a race core intercooler would). This intercooler can be totally plug and play so you don’t want to chop or drill something, so one other very good profit – particularly for M2 house owners as now we have alot of further bracing and shrouding that forestalls bigger intercooler from becoming correctly.
So I like to recommend this intercooler for people that simply avenue drive their automotive and are on the lookout for a little bit of further enchancment over inventory and dont wish to take care of reducing or modifying their automotive to get the intercooler to suit, or observe guys who have to optimize air circulation to the principle radiator to stop coolant overheating. If you’re drag racing, doing auto x, or actually need superior iat suppression and warmth soak resistance and are usually not apprehensive about: coolant temperatures, and reducing your automotive to make issues match (sometimes this solely applies to m2 house owners) – then I like to recommend getting a race core intercooler, as that may be a very massive intercooler that’s greater than succesful sufficient to supply cooling for even essentially the most excessive driving situations.
BMS Race Core Intercooler:
Now lets discuss concerning the BMS Race Core intercooler itself.
Transport:
First lets discuss concerning the delivery expertise, as a result of thats all the time a priority with such a giant product, and whether or not it would arrive in a single piece.
1) Transport/Processing: this intercooler was shipped by way of Fedex from California to Canada and it was extremely quick taking lower than every week to reach. Processing time was about 1-2 days after putting the order which was additionally extremely fast in comparison with different bmw components distributors who take eternally to course of an order. So general lead time was a tiny bit over every week from the time of order placement to the time it arrived on my doorstep. The intercooler additionally arrived undamaged and in good situation which is all the time good – and I attribute this to the packaging which I’ll describe subsequent.
2) Packaging: The packaging is outstanding with a thick cardboard field on the skin and extremely thick however gentle foam liner on the within. The froth itself was reduce out to be a clam shell the place the intercooler would sit inside an ideal reduce out for it. This mix allowed for excellent safety, as a result of the froth clam shell prevented the intercooler from shifting throughout delivery which drastically minimizes damages, and for the reason that foam was so thick it was in a position to take up all types of impacts and potential punctures earlier than it could possibly harm the intercooler.
Total the packaging could be very good and there actually could be no approach for it to be broken (even from a drop or abusive dealing with).

Unboxing:
Subsequent lets transfer onto the unboxing of this intercooler, so what you’ll get with it:
Credit score: F87Source
Credit score: F87Source
Credit score: F87Source
Credit score: F87Source
Credit score: F87Source
Evaluation and Overview:
Okay shifting on lets talk about some particulars of the intercooler itself (word I’ve used gold warmth reflective tape on my intercooler to try to reduce radiant warmth soak from the ac condenser core and the radiator):
1) Bar and Plate:
Credit score: F87Source
Credit score: F87Source
Credit score: F87Source
So the BMS race core intercooler makes use of a bar and plate intercooler design, as we are able to see from the pictures above. This implies the race core intercooler possess these traits:
– Excessive weight: Sadly because of the heavy responsibility bar and plate building and large measurement, these intercoolers are sometimes very very heavy – particularly when in comparison with inventory.
– Proof against warmth soak: These race core intercoolers are additionally extraordinarily immune to warmth soak since they’ve a lot thermal mass and floor space, this implies they may have the ability to take a number of laborious driving earlier than they begin to warmth soak. This is excellent for drag racing or auto x (very low air circulation more often than not because of the predominantly low pace driving, and thus you might want to have an intercooler that has sufficient thermal mass to maintain iats low), the place you wish to forestall warmth soaking as a lot as doable.
– Sturdiness: These bar and plate intercoolers are exceptionally sturdy attributable to their heavy responsibility building, so harm attributable to street particles needs to be very uncommon. I’ve truly run a BMS 5 stepped core intercooler for the final ~4 years and haven’t encountered any harm regardless of it being continuously bombarded with rocks and gravel from the winter.
2) Fins:
Credit score: F87Source
Credit score: F87Source
Just like the BMS 5 stepped core intercooler, the BMS race core intercooler makes use of non louvered fins with squared finish plates with a view to neatly stack as many fins as carefully as doable. This non louvered fin additionally permits the fins to be extraordinarily robust and inflexible and they’re exceptionally resilient towards harm attributable to street particles strikes, and as I discussed earlier than my BMS 5 stepped core intercooler has zero indicators of harm regardless of being pushed on the street for ~4 years and being continuously bombarded by rocks and gravel due (the town releases a number of this gravel combination to supply further traction within the winter). Now to compensate for the shortage of fin louvering BMS will stack 2 rows of fins proper subsequent to one another in a staggered vogue, this permits the fin density and thermal change floor space to be elevated and subsequently compensate for the shortage of louvering. It’s actually laborious to see within the picture above, however should you look carefully you’ll discover that there certainly are a number of fins stacked subsequent to one another.
The BMS race core intercooler additionally makes use of ~14 fins/cm (should you depend the staggered fins as properly), which matches BMS 5 stepped core intercooler (which is smart since they appear to share the identical core design) and doubles the fin depend of the inventory intercooler.
3) Stepped Core:
Credit score: F87Source
Credit score: F87Source
Credit score: F87Source
Credit score: F87Source
The BMS race core intercooler makes use of a stepped core design, this will increase the quantity of frontal floor space accessible for cooling over the inventory intercooler which lacks the step. Now, the essential characteristic right here is that the races core intercoolers have an enormous stepped part (each when it comes to peak and thickness) in comparison with the 5 stepped core intercoolers (just like the BMS choice) and even bigger upgraded intercoolers just like the CSF race type intercooler. This permits for a considerably larger functionality to dissipate warmth in comparison with basically all intercooler choices in the marketplace (with the exception possible solely being the considerably costlier wagner evo 3 which carefully matches these race intercoolers) making these race core intercoolers the head of iat suppression efficiency.
4) Steel finish tanks and connectors:
Credit score: F87Source
Credit score: F87Source
The BMS race core intercooler makes use of stable aluminum finish tanks and connectors for the inlet and outlet aspect, this implies the intercooler is exceptionally sturdy and will by no means have points with cracking or materials fatigue.
5) Dimensions:
Credit score: F87Source
Credit score: F87Source
Credit score: F87Source
Credit score: F87Source
Credit score: F87Source
Now lets rapidly look at the dimensions of this BMS race core intercooler:
Fundamental Core (L x W x H): ~60.5 CM x ~13.7 CM x ~15.2 CM
Stepped Part (L x W x H): ~60.5 CM x ~8.3 CM x ~13 CM
So the principle core has a frontal floor space of: 919.6 cm^2 and a complete quantity of: 12,598.52 cm^3.
The stepped core has a complete frontal floor space of: 786.5 cm^2 and a complete quantity of: 6,527.95 cm^3.
Thus the full frontal floor space of this BMS race core intercooler is: 1,706.1 cm^2 and the full quantity of this race core intercooler is: 19,126.47 cm^3. That is considerably bigger than the inventory intercooler each with reference to frontal floor space, and whole quantity. The identical goes to the 5 stepped core intercoolers – once more permitting this intercooler to have considerably higher thermal dissipation.
6) Mounting Tabs and {Hardware}:
Lastly the final space I wish to analyze is the mounting tabs and the mounting {hardware} for this race intercooler, and the rationale why is as a result of a number of bigger aftermarket intercoolers have horrific mounts and reuse the insufficient inventory screws (in case you have seen the unique CSF intercooler mounts precisely what I’m speaking about: https://f87.bimmerpost.com/boards/sh….php?t=1983878)
Credit score: ///MPhatic https://f87.bimmerpost.com/boards/sh….php?t=1983878
So the BMS race core intercooler does some issues in another way, they embody new and longer chrome steel self tapping screws that enable for a way more safe and strong attachment of the intercooler to the automotive – for the reason that inventory screws are approach too brief (they dont truly thread all the best way into the inventory plastic mounting tabs and realistically are just a few threads deep when totally screwed in) and are prone to corrosion. As you may see beneath that is the CSF intercooler supported by the inventory screws and a customized washer as a result of CSF didnt initially provide a very good high quality washer . You too can see the inventory screws rusting out.
Credit score: VisualEcho https://f87.bimmerpost.com/boards/sh…3&postcount=26
The BMS race core intercooler may also embody bigger chrome steel washers as properly, to higher distribute the load from the brand new screws. Now lets check out this new {hardware}:
Credit score: F87Source
Credit score: F87Source
Credit score: F87Source
Credit score: F87Source
– In order seen above these are the brand new chrome steel phillips head self tapping screws and chrome steel washers that you’ll be getting with the BMS race core intercooler, you may also see how properly the chrome steel washers match the mounting tabs on the BMS intercooler. Subsequent is a distinction and comparability to the inventory mounting screws:
Credit score: F87Source
Credit score: F87Source
Credit score: F87Source
Shifting on I wish to take some measurements of the inventory plastic mounting tabs, and measure how far the brand new screws will faucet into the mounts – this fashion you will note how rather more efficient they’re and the way rather more safe the brand new mounting screws can be:
Credit score: F87Source
Credit score: F87Source
– In order you may see the complete depth of the inventory mounting factors are ~ 22.08 mm deep.
Credit score: F87Source
Credit score: F87Source
– The brand new self tapping screws with 2 washers put in will protrude precisely ~22.08 mm deep however technically will probably be a number of mm brief as a result of when the intercooler tabs mount up it doesnt mount completely flush. They really mount at a slight angle (for the reason that helps arent going to be completely sq. as they’re pushed barely outwards by such a big intercooler) and also you see a number of threads of the screw, so that you perhaps lose 1-2 mm of depth.
Credit score: F87Source
– Lastly the very last thing I wish to present is the inventory screw and as you may see it solely protrudes ~12.20 mm, which leaves 10 mm of additional area remaining contained in the inventory mounts, and the inventory screws can solely thread in ~4 threads deep. IMO it is a actually horrible solution to help such a big and heavy intercooler, and I don’t really feel secure with an intercooler solely hanging on by ~4 threads. So I’m very happy BMS included new mounting {hardware} that makes use of all the depth of the inventory mounting tabs – and that is good as a result of not many firms do the identical. So general this new {hardware} ought to have the ability to adequately help this huge race core intercooler beneath all situations.
Set up Ideas – Particularly on the F87 N55 M2:
Lastly I wish to speak about set up on the F87 N55 M2 particularly, in case you have every other F collection N55, set up needs to be pretty easy as it’s pnp. With the M2 you might want to make some modifications, in order thats why I can be speaking about it in depth.
1) Thermal Reflective Tape: I like to recommend taping the intercooler with some thermal reflective tape to reduce radiant warmth soak from being so near the ac condenser core and the radiator. Ideally you solely actually need to tape the highest of the principle part of the intercooler the place the underside of the stepped portion is (that is the place the BMS badge is welded on) because it sits cms away from the radiator. However I taped a number of additional sections to assist reduce warmth soak as a lot as doable, whereas additionally avoiding taping too near the entrance aspect of the intercooler so it isnt seen with the bumper on.
2) Bumper removing: Subsequent you will have to take away all the entrance bumper, as a result of you will have to take away the entrance crash beam with a view to take away the V brace for reducing.
3) Crash beam removing: Take away the big heart crash beam, they’re solely held on by 2 torx bolts (you will need to exchange them after each use as per BMW) per aspect. The bolts nearest to the middle of the automotive will hit the top mild and it’s laborious to take away since clearances are so tight. So I counsel taping that part of the top mild with masking tape after which loosening all 4 bolts. It will will let you push on the bumper brace and get it nearer to the automotive which will get you extra slack on the bottle permitting you to jiggle the bolts free. The tape will forestall the headlight from getting scratched.
4) Take away the intercooler duct: You’ll need to take away the kidney grille shroud (that is reinstalled later) to take away the V brace and to totally delete the intercooler duct utterly, they’re held in by 4 screws on from the highest, the consumption snorkel which you’ll have to push by means of the shroud, and by 2 pop clips on the aspect held into the body rail:

– That is the snorkel it’s important to push by means of to take away the shroud. The snorkel is rubber so it is vitally versatile, and so that you simply must shove it by means of the shroud in the direction of the proper.

– Now you may take away the intercooler shroud (pictured above) and both preserve it in a secure area or throw it away since you’ll not be reusing it, and you’ll see the little tabs that clip into the body rail that you might want to take away.
After eradicating all the pieces you automotive will seem like this:

5) Lower the V brace: You’ll be able to set up the intercooler at this stage, after which line up the V brace and reduce it nonetheless you wish to clear the intercooler. You will need to reduce the v brace in any other case it is not going to match. I used a rotary instrument with a reducing wheel to do the cuts, a hack noticed could be wonderful, and the identical goes for angle grinders. BMW stipulates you will need to exchange these bolts as properly since they’re single use.
Nonetheless, I like to recommend reducing the v brace like Westersund does on this thread (https://rejsa.nu/discussion board/viewtopic.php…cd8609#1768622) – as a result of it would will let you run Westersunds intercooler shrouding package at any time when he releases it.
Listed below are some photographs:

– That is the picture of the v-brace, I like to recommend reducing it on the purple strains I’ve marked within the picture above. Now achieve this with the observe measurements that Westersund supplies beneath:

Right heres my very own brace after it was reduce (I taped the ends with tessa tape to additional defend it from corrosion, however I additionally clear coated all of the reduce metallic ends as properly):

Afterwards you may take away the v brace for portray, and you will have to reinstall the kidney grille shroud earlier than reinstalling the v brace completely.
6) Now you may reinstall the kidney grille shroud:
– Set up it the reverse of eradicating it, however you’ll discover nothing will clip it into the body rails as a result of the intercooler shroud had the little clip tabs and since we deleted that half these tabs are gone too. So to interchange these clips I used an m6 screw with a brilliant vast head, 3 m6 washers, and an m6 riv nut. The primary washer will sit beneath the screw and on high of the plastic tab, the second washer sits beneath the plastic tab and on high of the body rail, and the final washer sits contained in the body rail and on high of the riv nut. You’ll need to make use of needle nostril pliers to achieve into the body rail and maintain the riv nut so you may thread the screw in, additionally, you will have to have fairly good stability to carry the riv nut regular so the washer doesnt fall off.

– Alternatively you would use a nut as an alternative of a riv nut, however I discovered the size of a riv nut and the textured sample on it was simpler to grip with needle nostril pliers vs. a bolt. You may additionally set up the riv nut into the outlet on the body rail as BMW has carried out in lots of locations, nonetheless I opted out of that as a result of I believe you might want to take away the top mild with a view to get sufficient clearance to take action. Regardless this answer remains to be very robust, and as soon as all the pieces is tightened down there isn’t any motion or wiggling in anyway, the shroud could be very properly secured like this. Plus the washers I used have been the proper thickness to fill the hole between the plastic tab and the body rail.
After the shroud is put in you may reinstall the v brace, entrance crash beam, after which the bumper. Thats it! You are actually carried out.
Put in Pictures:
Lastly listed below are some photographs of all the pieces as soon as it’s all put in:

– Total fitment was fairly good, all the pieces could be very tight but it surely all match properly – no complaints from me. The one problem for m2 house owners is reducing the V brace, clearly I want this might be averted however we dont actually have a selection on this matter.
Testing:
On to testing, I’m simply testing this based mostly on avenue driving as I dont actually have a lot time this 12 months to knowledge log and take it to the observe (I already went to check out my paragon pads, and I cannot be going again).
Regular state testing – driving the automotive at a gradual 110 KM/h in sport + mode in 30C ambient temperatures. The automotive is off load, so no increase era.
BMS 5 Stepped core: I seen IATs at their lowest was 8.5 C above ambient temperatures beneath these situations. I’ve carried out lots of of drives over the previous 4 years with this intercooler and this was the most effective I’ve ever seen.
BMS Race core intercooler: I seen IATs at their lowest was 7C above ambient temperatures beneath these situations. I think that this might be even decrease if shrouding was added to encompass the intercooler, as a result of I really feel like alot of air is flowing across the intercooler core itself (by way of the big gaps launched when the shrouding was eliminated) and never by means of the core. This clearly will sacrifice some cooling efficiency, and with some shrouds in place the cooling efficiency can be considerably higher.
I can be buying an intercooler shroud package from Westersund to check this concept out, and I can be making a assessment on it as properly:

Pulls – I accelerated from 2500 rpm in third gear to redline and shifted into 4th gear, just about customary knowledge logging habits. Once more 30C ambient temperatures.
BMS 5 stepped core: With the 5 BMS intercooler I seen iats would improve 7C – 10C from the begin to the top of the pull. So probably not nice however not too horrible.
BMS race core intercooler: with the BMS race core intercooler iats by no means elevated from the begin to the top of the pull, however extremely IATs would truly lower a number of levels from the begin to the top of the pull. I think the rise in each street pace and air circulation by means of the cooler itself aided in growing cooling efficiency on such a big intercooler core that wants the additional air circulation to see the good points in efficiency. Even with again to again pulls iats have been rock stable. So very spectacular iat suppression with this intercooler.
BMS vs. Rivals:
Lastly the final little factor I wish to talk about is BMS vs. the competing race core intercoolers, and thats the VRSF race core and the MAD race core intercooler. All of those rivals are similar to the BMS providing, and actually it in all probability comes right down to pricing and customer support. The BMS race core intercooler is available in at $499.00, the VSRF race core is available in at $479.99, and the MAD race core is available in at $469.00.
So pricing sensible they’re all inside $30 of one another, so IMO it isnt a significant distinction in any respect and I might be on the lookout for the choice with the most effective customer support. Thats why I selected BMS, as a result of they’re famend within the BMW tuning group as having the most effective customer support round – and so they proved it after they changed my defective intercooler with out problem (asking a bunch of mindless questions, making an attempt to push blame upon me or the delivery firm, or ignored my emails and so on) and didnt cost me a dime to take action. I can’t say the identical about any of the opposite firms, so IMO it’s all the time finest to purchase from an organization that’s well-known for his or her customer support, as a result of if something dangerous have been to occur you dont have to fret about whether or not or not you’ll be taken care of.
Abstract:
So general I actually love this race core intercooler by BMS, it suits properly, has wonderful efficiency, and is general a stable product for the value.
