Hi everyone ,I have made a research but didn't find anything. I have datalog my car and I saw the map drooping from 980@4k rpm to 915@ 8k2 rpm . PA is 1020 and engine off is aroud 1000 I think that my intake is reducing air flow . Is that right ? What intake can you suggest for my setup : B18C6 Engine (12.6 Comp) RM 22 Motorsports cams Stock Intake manifiolds 11.9 JE pistons +.3Supertech dish valves +.4 Head RM 22 Motorsports cams ITR stock air box Thank's a lot .

Hi you are right you're lossing air flow perhaps a bigger throttle body at first and then another manifold the best would be custom one or go for Edelbrock, golden eagle...

I've tried a friend's intake , 3\" alloy tube with big green cone , Map goes now from 1010 to 990 , witch I think is reasonable . I've datalog a stock integra with Mugen air box , the map is dropping to 970 . Julien .

sounds better. Sometimes I have even seen higher than atm. pressure at WOT when induction is really doing it´s thing :) /Allan
