is build by a company or custom fabricated? thanks

[3thirty5]

i remember reading that it's custom made.

Whats a FMIC ???

Are there RMIC's (rear mounted intercoolers) or SMIC's (side mounted intercoolers?

[Driver72]

No, but their are top mount intercoolers.
As for which or who makes it, it really doesn't matter.
A larger, more efficient FMIC on our cars will all do the same.
There is really only so much room up there, so the difference between the makers versions will probably be little.
I think there are 2 or 3 companies that now make the FMIC for the 335i.
BTW, the power gain from them is minimal, but you will keep heat down more which allows you to have more power longer without heat soak, which helps a lot in road racing or autocross and the like.

Big FMIC will help already at the latter part of Walked U's soon to become 0-180mph.

180 mph in a 335i sedan on stock suspension and without knowing the aerodynamic capabilities of the car at that speed would be silly.
I hope before Walked U pulls his rev limiter he better get to a proper track and slowly build up the speed past 160 mph and see how the car handles it.
He might want to consider a small trunk lip spoiler to add downforce at that speed to, and check into the lift on the front end of the car to make sure the front wheels don't skid off the road at those speeds too.

A LOT more to consider before just removing speed limiters in a 4 door luxury performance sedan and going balls out.

Stock e92 is extremely well balanced aerodynamically. Sedan can be worse, but that I don't know. I bet his friends have just removed the limiters from their luxory sedans without thinking about the aerodynamics. I agree though that it earns a thought.

[fusionchicken]

isn't the e90's Cd something like .30?

the UK Evo fq400 with a Cd of .35-ish can hit 175mph, the 335i can do it with .30.

though i agree the downforce aspect needs to be taken into consideration...but when most people take their car up to high speeds it's only for a short burst of fun....now if we're talking about maintaining 180mph on the autobahn then yeah, we should start worrying more about adding downforce on the front and rear of the car, IMHO.

+1 very good point.

The core is built by a company. The end tanks were custom made by that company. Then my fabricator had to cut / relocate things to make it fit. Custom bottom valence / duct work was made also.

Lol just PM me next time if you have a question.

Coefficient of drag doesn't have anything to do with stability at speed.
Just how "aerodynamic" the car is.
It does not measure lift, downforce, swirling wind under or around the car, etc.
Even at short bursts, it only takes a split second for the car to "take flight" if the aerodynamics are not up to the speed the motor has been built to do.
My point was just it's something for one to think about in the name of safety before removing a speed limiter.
Later.

i've never seen or heard of a rear mount, but there are plenty of cars with stock side mount intercoolers. 1.8T VW's, Mazdaspeed Protege's, SAAB 900's to name a few.

Lots of side and front mount intercoolers.....never heard of a rear one either.

they do infact exist, theres these cars, and like, their engines are in the back


no seriously rear engine FI cars exist and their intercoolers are in the back being fed by ducting

[M3SWEETNESS]

Every position mention does exist. Ex- top mounted( Subaru STi's), Side mounted (Toyota Supra), Front mounted(BMW 335I!), rear mounted( Toyota MR2 Spyders) just to name off a few...

roof mounted?

[M3SWEETNESS]

Roof mounted, no..... Top mounted as in on top of the engine.....

I stand corrected, there is such a thing is a roof mounted Intercooler. Lol http://adsportonline.com/MR2/intercooler.htm

Btw 335i e92 lift at rear axle at 200km/h is only 28kg. If you were not worried about having lighter wheels and lighter catback resulting in similar reduction in the force downward, you shouldn't be too worried about the lift. I don't know the respective figure for e90. M5 e60 has also extremely minimal lift at the rear axle at 200km/h; 19kg. Thus Sport Auto concludes that there is no problem to remove its limiter and drive 300km/h.

Aerodynamics is important at high speeds, and I would not add anything for my stock e92 with tested and good aerodynamic figures without tested and proven enhancements. However, if there is info about e90 having huge lift at the rear axle, then the small rear spoiler could be used at the expense of slight decrease in high speed acceleration as the spoiler increases drag, though just very little. You could feel the car to be a bit more planted at the curves at 160-180mph, since at high speeds the small M-style rear spoiler should reduce lift; some 45kg at 150mph, and at higher velocities even more. Considernig the total weight at the rear axle, you really need to push it to its limits at the curves to feel the difference. But if you try to keep the speed at 180mph at each curve, at some point the minimal additional downforce can be priceless.
