Heat shield options?

E36 airbox, tell me how!

[MIKe30]

wow, details please? Looks gorgeous...

If you have an early model you can use a stock E36 airbox with some slight mods.

an eta airbox is going to be highly restrictive on a 24v engine, if I'm losing 10whp from the B25 airbox on my stroker

would it be possible to retrofit the factory airbox from a different model? to try and look factory?

made one from an 528e..

Someone with half a clue and some time could always make one for 10 dollars.

Fixed that for you. Sadly, I am neither, and would prefer a (hopefully) quality functioning piece rather than a hack job by a know-nothing dipshit like myself who has no business doing anything but driving a car.

I wouldn't make it out of metal. The whole idea is not to transfer heat through. There was a dude at the E30 picnic who had one made of some sort of composite material, looked fantastic. Otherwise I'd be buying a sheet of ABS plastic.

the temp difference is phenomenal BTW. over 100 degrees - sucking in hot air from the radiator, well, sucks.

The heat shields I've had, that came with either the Conforti CAI or the ECIS intakes, were all composite. I was surprised to see that my ECIS intake actually was composite with some kind of carpeted lining on one side.

Way back in the day, a shop called Boston Performance Group held a dyno shootout to test the manufacturers of shielded intakes for the E36 M3. While the results were close, the one constant was that an unshielded conical intake lost 8-9 hp on their dyno. I do not know if this was wheel horsepower or at the crank, but I've known this since before I bought my M3 in what seems like another lifetime. It kills me because I know I am hampering power at least somewhat with my current setup, so it's time to try something.

Want photos ASAP of the setup. I am interested.

Actually, I'm using two zip ties linked together to hold the HFM to the stock AFM bracket, and no heat shielding.

I was in negotiations with BimmerTim to design something that'd give me an intake resonance at 7500 rpm to create a shockwave that would stuff enough air into my M50 manifold to boost the engine to 105% VE, but sadly, he had other engineering products on the table that took precedence.

Those "other products on the table" were part of a joint effort between us to adapt 5.0's to e30s, once he found out he can't make 672whp with a stock s50. Even with a Signature Motoring heat shield.

If you are looking for a high end part made of kevlar and uranium, look no further then FredK's marvel of engineering which was probably purchased from whichever retailer had the highest price at the time. Schneller? Korman? Adam Hanson? The world may never know...
