Real world 500-600RWHP 2V blower combo
|
Shortblock - iron block bored no more than 0.020" over with a good forged rotating assembly Heads - our Stage 2 PI heads Cams - our Stage 2 PI Blower/Nitrous cams Intake - stock plastic plenum/TB - BBK 1780 Cat back - only Magnaflow and Borla show good gains from what I have learned but I have not seen them all The blue graphs are stock PI heads and stock PI cams, red is the Stage 2 head and cam swap gain only. Same boost levels, 108RWHP gain peak to peak (540RWHP peak), no loss of bottom end torque, and another 500RPM of usable range. Noticeable idle and good street manners.
