E30 24V Intake Set-Up

[scottinAZ]

I'm no expert on the matter, but from what I've read, a K&N mounted to the MAF is not the most efficient intake, not to mention it will be sucking in hot air from the engine bay.

this is what I have currently. Not the best, but it works. I have a Kamotors intake enroute, so its a temporary situation at best.

I'm new to the platform, but I did notice an awful lot of set-ups with the Filter Element bolted directly to the MAF (most notably the 3.5 HFM). Can you explain to me why this is efficient?

Working with the e46 platform, we obviously have a little more room in the bay...But I'm running a long tube intake with a filter element tucked into the bumper. Significantly more air is read by my MAF because the flow is smoothed out on it's way from the Filter to the MAF. Others have implemented a Velocity stack-type element with a larger filter attached in front and a length of silicone between the element and the MAF.

Just curious because it seems like there may be better ways to route the filter...especially just leaving it open in the bay...but really wondering how the 3.5 HFM really works and if any of what I mentioned above is even necessary.

Cheers!

What mech fan are you running?

What shroud is he running as well????


Fan looks to be a late model 11 blade. Im running the 9 blade early model fan, and have about 1/2 inch clearance to the rad

Here's what I made one afternoon. It's made from aluminum sheet metal and an engine bay gasket I found in my garage. I'd like to take it out and paint it black, but it works very well at keeping heat out. If you look beside my ABS pump you'll see some 3" tubing that takes air from the front brake duct.

Thanks bubbajan21, for posting pic's. Anyone else who interested in our CAI box, PM me or POLAK.

where can I buy a castros box? :D

Non-ABS E30s can fit the E36 Intake no problem into that space with some very slight trimming on the bottom of the intake.

If you relocate the ABS you can fit it. And you can just put the ABS on PASS shelf.

Just FFT

I passed visual. Sniff test failed. Buying new cats now

you think it will be sufficient for BAR? It was a PITA to cut the box in half, and somehow make it fit. I tried bending the e30 airbox mounting bracket as much as I can

Ya, Danny passed with just a K&N filter on his MAF.

I know, just being a prick. :p

yeah, but my goal is only to get the sticker lol then I will be buying a castros box

I have my BAR appt tomorrow. Here is a picture of how my intake is, and then a picture of how I am going to bring it to the appt. lol

Both intake set-ups aren't very efficient. Your first one is a hot-air, short ram set-up. Then you have the e36 airbox, with a nasty restriction in the intake boot.
