F.A.S.T LSX 90MM Manifold and TB For a heads and cam car, how much would a lsx 90mm manifold and throttle body help out? I dont think i am getting enough air through the motor. I have TEA stage 2 5.3 heads and the thunderracing 236/230 cam. Right now i have a ls6 manifold and stock throttle body. Thanks, Casey

what's your max MAP and at does it hold all the way to the redline or does it drop off?
best way to check it out is to grab a log (i use HPT so that's all i know, but it should work with anything else that can export data) and do data->auto filter on it all, then click on MAP and tell it to give you top 100 (or 400 if you want a bigger picture/have more data) and see how it spreads out. really gives you a good understanding of if you got a intake tract bottleneck. I wrote more about it here: http://redhardsupra.blogspot.com/200...nd-intake.html
another thing to take a look at is your MAF/Dynamic Airflow numbers. My stock head/headers+granatelli maf+lid+filter+ls6 intake will top out at 40-42lb/hr of air. big head/big cam cars will go over 50. so just ask yourself how much it's worth to you
let me know if that helps you any.
