I've always thought of doing one, but I changed my mind into just a good CAI. However there are two ways I'd do it.

1) Cone filter where battery normally is. Seal off that entire area from headlight to shock tower to make an airtight box. Put Renault Twingo or similar air intakes above the sealed box in the hood. Done.

2) Cone filter where battery normally is. Seal off that entire area from headlight to shock tower to make an airtight box. Duct air up into the box from a high pressure area at the lower-front of the vehicle.

I dont think you would get much results with a short ram. I put a velo stack on my gsr and that made a huge diffrence I was planing on doing the same with the sr but I just bought a t25 for it..air straight to the front bumper has anyone tried that?

IMO tuning will not be effective because turbulence is erratic by nature and its impossible to fully anticipate when and how it will affect the maf output. The MAF is very sensitive to changes in airflow, something as small as a gust of wind will alter the MAF signal. If you have a WAI you can actually blow into the filter at idle and see what happens. An 18-wheeler's wake will definitely f with your AFR on the highway if the maf isn't sufficiently protected from turbulence. The only way i can see this working with a WAI is what Ben suggested above.

An 18-wheeler's wake can literally rock a medium-sized car from side to side, and that will definitely f with your AFR on the highway, in ways you can't possibly predict.


This^ is what happened when people tried it before. Its what will happen if you try it. SE-R is not a Firebird.

I have option 2 on my NX, wanted to do 1. Here's the pix. I made this with some creativity, HVAC aluminum ducting tape, styrofoam coolers, an aluminum dryer vent tube, and a gutter drain spout.

Mike K did a comparison with dyno numbers on several popular intakes many moons ago. IIRC, they were PR, HS, and AEM. It was on the old forum...I'll see if I can dig it up.

HS produced more gains with S3's and bolt ons

Yes, I am using a N60 Maf right now, it seems more sensitive than the stock De throttle body though.

I think I know the article you speak of but it didn't have in anything about a ram air set-up that I can remember. It was a good article though.

Thanks for the ideas Ben. Your running the AEM engine management correct bro? I

I remember that, and the only way the HS produced better numbers than the PR was after he upped the FP iirc.
