I was reading some guys testing on turboing a sr20ve and he said that they had 11:1 compression stock. He also said to turbo the sr20ve, you will have to get the compression around 8:1 or 9:1. Why? I thought the better the compression the better the power. Maybe it would be too much if your going for efficiancy? Just curious. Thanks
You can't run as high boost in a high compression engine due to detonation (inother words, you can run higher boost in an 8.5:1 comression engine than in a 10:1 compression engine). Most forced induction engines have 8.5:1 compression or lower.
yeah, imagine building a high compression,lets say 12:1, N/A motor..makes 240hp, but you want more..so slap on a turbo with the compression still 12:1, you run the turbo at 7psi..at the moment our engine makes boost, your engine goes BOOM!..thas whatll happen..this is a dramatized effect because the high compression Matrix(11.1:1) can be turbo'd at 7psi, but you need high octane gas..8.5:1 is the norm..

right now i am running 10.4.1 comp, and a fully build motor with gt35r turbo and running 10psi on pump gas and it runs very very strong.I just poped 3 gear @ 10psi runing up and down the road and yes the tranny was cryoed.also i get boost @ 2800rpms
