I have engines tested in either of my engine dyno labs, install them into the car and generally see a 13-15% difference from flywheel HP to RWHP consistently.. Thats how I know our numbers are spot on.
yes, i think its kind of strange the guy that dynoed right after me was around 40 hp under what he is used to seeing. that would put me exactly on the average you said you see for an S. 223 hp. i'll look for a dynojet.

thanks
