Oh ya! that was a bad *** setup, I'll get Eric or Rich to find the pics and post them up. So when is a CNC head going on that car for mega high rpm power?

 

Nice intake!!

 

Lower inlet temps also mean a higher mass airflow choke limit and less energy requirement from the compressor to compress the air.

Less energy used in the compressor means lower exhaust back pressure.

These same arguements can be made about inlet pressure at the compressor wheel as well. All the small stuff can really add up...

 

We experieneced the same situation when tuning this evo in E85.

We were actually experiencing some tuning issues because the dumps were allowing exh gasses to be recirculated into the intake w/ the position of the filter.

We threw on a 4" sec of tubing out of the engine compartment and HP picked up dramatically and allowed Sean to tune it properly.

We also noticed a solid 15HP just in removing the filter alone.

We plan to fab up a 4" intake pipe that draws air through where the driver side headlight is w/ some sort of air-box (not so much like Indy's but smae idea)

 

EXACT-A-MUNDO! nice post.

 

Finances are teh suck right now. As soon as the economy picks up and I unload some real estate ... CNC head and cast intake mani are on the list. Although I get the feeling that the 50 trim is close to maxed out already. Guess we'll see once the parts go on. If I get enough funds next year, I might see about doing some back to back turbo testing on my car. Car's been running like a champ, though.

Pic of the initial 3" setup:



I'll see about snapping some pics of the 4" setup later today.

Do you have more angles of that air box it looks like a nice piece

Does AMS have that on their site? Haven't been on it lately.

I take it the headlight is non-existant?

 

When u say 3" is that the outer or inner diameter?


Tks

I think that he must mean that he went to a filter with a 4" outlet diameter, straight on through a 4" I.D. inlet pipe feeding a turbocharger compressor wth a 4" inlet diameter.

The diameter of the filter itself at its base and probably at the top as well would be larger than 4". At least that´s how I happen to visualize it.

EDIT: Now that I looked at the pics I´m not sure that my imagination served me well. The pic of the original 3" inlet where it exits the cold air box looks like it is already a 4" diameter piece. Now I´m confused.
