Guest Cronic Posted May 9, 2004 Share Posted May 9, 2004 In low gears I cannot keep boost at 19psi for more then 4000rpm, after which it drops to 15psi. I noticed this at the track last night. On the street it holds it all the time, mostly cause Im in 4th/5th gear on the street. And in 4/5 it has no issues holding 19psi. Stock turbo, stock wastegate, GReddy profec-b, HKS SSQV bov. FMIC, 3" exhaust. Quote Link to comment Share on other sites More sharing options...
240hoke Posted May 9, 2004 Share Posted May 9, 2004 I wouldnt be surprised at all if the stock turbo just cant flow enough air to run 19psi in third gear. I know i wouldnt have done that with my t3. I thought hte max they could do was 18 and that was really pushing it. Anyhow im not sure if this makes sense or not, but isnt there more load on the engine at WOT in 4th and 5th then in 3rd since the engine is geared lower? I dunno i just figure more load = more boost -Austin Quote Link to comment Share on other sites More sharing options...
