Being an author of a turbocharging book I trust that calculation... Some say it was 30%, but that sounds awfully steep to me. My only other issue is where the cone filter ends up... I don't want it in a spot in the bumper where there is negative air pressure because then never mind just the bend losses... now your working harder to even find air.

with four 90* bends, you'd be at -20% flow... wow.

CAI's and WAI's are overrated..
SAI's are where it's at: http://www.3500z.com/60degree/Intake%20Stuff/SAI.jpg
BTW, my CAI only had 1 bend in it and consistantly performed better than my WAI while sitting in the staging lanes and while moving.Comment

for the life of me, i cannot figure out what the S would be...
and does the tube stick out beyond the back of the light bucket?Comment

headlight funnel directly into the 3.5" intake pipe.. track use only
Small Animal Intake :PComment

as soon as i can find the clips to hold the headlight together i'm going to cut the front out and epoxy some metal mesh across it.
that would suck if a bird got in there.. bugs i'm ok with though.

It's not the motor that did it but I did gut a bird on the grill of my beretta... face planted right on the Chevy emblem, and his stomach and intestine ended up in my safety latch depression on my header pannel... It was gross, but damn I got some good close up shots of it! LMAO...
SAI I love it! If I had a better way to run a CAI I would but I just don't know where to direct it, first things first, the battery has got to go soon...
The only route I can make is two 90* bends and at least one 45* bend, but that puts my filter only to the left front corner of the bumper, behind my washer tank, and open to air that goes through the radiator first... there isn't really a direct shot of air into that compartment, that's the big kicker about my setup.Last edited by 3400-95-Modified; 08-28-2009, 09:08 AM.

Loss of power would be 2.5" from each manifold.
Keep that 2" and you will be fine. Maybe even 2.25" would be ok, but 2.5" for the whole motor is best, and you have that on each bank..........sigpic

my CAI sat in the cavity under the battery tray with a shield from the engine side. The air inlet to the cavity was the mouth of the front bumper.
I pulled out the filter last night, after a year of spotty driving it was still clean. No water marks, mud or bugs.Comment

Too late, I already made them. Besides the output from the front manifold is only 1.75. I stepped up the pipe just for looks about 4" from the manifold. But your right.
Originally I was running the 1/4 in 15 flat with full exhaust. I dumped the exhaust and went with a 2.5" straight pipe that ran to the gas tank, about 4 foot long. I went faster 14.50's. I was trying to "tune" the pipe the old fashioned way. Spray a paint line down the side and cut where the paint stops burning off.
Funny thing is, the paint never burned.....ANYWHERE! and it was normal paint, not engine enamel. So I pulled it, the whole pipe. Damn if I didn't run 14.70's from then on out. But then I saw a post where someone stated about figuring your exhaust size...and a guy named smokey..... ya something. Anyway, I figured when I went with the larger intake and TB I would compensate for the open exhaust. Well thats my theory anyway. We'll see. I'm going to try for the track Tuesday. I want 13's before the end of the year. Oh, I'm also going to put some good gas in her. The varnish smelling 3 year old stuff is finally almost gone. yes, this is how tight I am, I have yet to put good gas in her!sigpicHow to make High performance Emissions:
A "true" High flow converter, straight pipe.
Low/No flow EGR valve, block off plate.
Carbon canister and purge valve mod, place in large 30 Gallon can, cover, and place curbside, the city will do the rest.
PCV valve and vent tube, reroute to exhaust to dump where it belongs, on the ground. Or add breathers and let it all free.Comment
