Ya, dyno's and flow bench's are always sceptical??? I ALWAYS see "on a CONSERVATIVE dyno" or "on a STINGY flow bench" when people talk about either. I have NEVER seen someone post "I made X amount of power on the dyno, but we all know his dyno reads high, so who really knows?"
There are 3 dyno's in my area that I would use. Fj Smith the SuperStock chasses legend. Konigshofer Motorsports, MMPS guys for YEARS and another guy. I have seen motors on the variation of the 3 and there very close. PLUS we have seen those #'s from them run on another ULTRA high-end Mustang chassis dyno. They run the 1/4 mile on it, and usually shows close on the power, and cars repeat there Mustang dyno ET's at the track within .10.
I also seen a valve cover gasket cost 30Hp? My chew Chief, Konigshofer, had is HS 360 inline headed for on there to break in. We made a pull, reset the valve, and instantly LOST 30.8Hp. A gasket had been sucked in.
So little details need to be checked all the time.
