g60rc 0 Posted February 10, 2006 hey again, just remembered somthing, i took my C to a tune up on a rolling road...he fixed the problem there was (it was down 21bhp on a boost leak), then he took it to the red line in 2nd and 3rd. All was ok and he told us i had 164.1 bhp, then in the car on the way home i read the psi reading on the printout. It was 17.5 PSI , now is that for the charger or engine(i have no idea if an engine can have a reading for that?) because i read on another forum that, that was a reading for a heavily ported charger with 68mm pulley? He never attached anything to the charger so would this be right? and if i did have a 68mm pulley and Ported charger the bhp would be 190ish wouldn't it? any help would be good rich Quote Share this post Link to post Share on other sites
