E36 style Cold Air Intake behind front bumper?

[CMG]

Yeah the lower it goes the more dirt and water it sucks up. I don't have enough room with the ABS system to put anything down there unless I cut into the frame and not gonna do that.

Dorkel or go home.

Make it giant for the ram- air effekt.

t
Dinan V1 intake for the E46 sucked air from inside the LF wheel well.
Any power gains were soon negated by pumping losses as the dust and
grit machined the engine to second overbore....

Just remember the closer you get your intake to the outside the closer it is to a ton of water when you hit a big puddle.

What exactly are you trying to achieve with this CAI setup? If it were me i would adapt your m50 to a stock m20 airbox.

I will look into the m20 airbox. It would be an improvement, but ideally it would still need a snorkel to get some fresh air. I am not trying to make it lower, just colder for efficiency. I have experience driving thru flooded streets, the main issue with hydrolocking occurs when you WOT thru deep water.

Keep in mind that the longer the intake tube, the harder the engine has to work to pull air in, negating any effects of colder air. The shorter the better.

The E65 airbox was too big so now gotta try the E32 or E34 airboxes. If you happen to have a spare one to donate for R&D let me know.

I've been checking out the stock airboxes for the E65/E66, and I'm going to try to get one and mount it in the general area where the stock airbox would go, and I think I'm gonna try louvering the hood rather than ram air scoop style. We'll see.

So now that we're into winter I've really been noticing a difference in performance in colder temps. Butt dyno feels like it gains 10+ hp, and call me crazy but I don't seem to hear much pinging during higher loads at lower rpm. Every M/S/50/52 I have ever had has that problem due to crappy lower octane CA gas. My latest thought is rigging up a sort of intake box with a flat filter on top, then sealing that to a ram air scoop mounted on left side of hood. Lots of room there but only thing is power steering res underneath. A second option is running 3" accordion hose to above abs pump and into an intake horn mounted on driver front of hood, and it could stay attached and flex when hood is opened. I don't see any way to mount any kind of intake with air coming from the front of the car. Thoughts? Anybody seen any examples?

I don't have the capability to properly cut and bend sheet aluminum, but that's a good idea of making a cardboard template and finding someone to make it.

24v C.A.I. obd2





This C.A.I. came with a metal shield that can be shaped for e30 use, it has rubber edging because it is unbelievably sharp. You could probably fabricate one from sheet aluminum or galvy.

I'm in the works of making a cold air intake with seal on top while still being able to use a decent size filter

I gave up on this a while ago, There just does not seem to be any room anywhere other than the engine bay or removing a headlight to route a somewhat functioning CAI. Guess I'll just keep the piece of crap KA intake until I can find some type of thermoplastic intake or heat shield that will work.

I just realized I did not mention that car has an M50 swap, so not talking about stock engine. I'll try to get some pics to show what I'm talking about. Not concerned about hydrolock from sucking up puddle water here in Cali. Intake filter would be relocated in area next to horn right above brake duct, and a hole could be cut in the duct or re-routed directly to intake.

thats what my airbox looks like, nice cold air hole right behind the headlight. mine is missing the pipe that comes out of airbox, one of these days i might replace that....

hack away if you want, but behind the headlight is as good of a place as any, and you want to keep the intake inside the engine bay to a degree so if you hit a big puddle you avoid getting too much water in it.

Yes I am aware it will not do much for horsepower, but would definitely lower intake air temps. Right now it has a KA motors intake which is a piece of crap. What "stock airbox" are you guys referring to, M20 or M50? I'm just thinking about doing it because I have the parts in hand, and it would actually be functional. A secondary benefit is that it would clean up that side of the engine bay too. Car has a salvage title, so don't care too much about hacking into this one.
