325rwhp=400bhp??? havent posted here in a while, but im buying a sbc for my dad and i just told him its going to make more power than my ls1, my car dynoed 325/342 a couple of years ago
everything im finding says the combo im putting together makes 450bhp, so i figure mine will make around 400 since im not a freakin magazine lol
but when i told him it should be good for 400bhp, he said that its less than my car makes, so i went on to tell him my car made 325rwhp, so roughly 380bhp
he insisted that when he was called to pick my car up from the dyno (i must have been working) that they told him it made "320 something at the wheels and 400 something at the crank" and he could pick up the car and graph (he couldnt remember the exact numbers since it was a few years ago)
so is it possible that my car did make 400 at the crank or did the shop that dynoed it just used a messed up calculation to figure out crank hp from the rwhp

ok, now that im thinking about it, and the more i look, my car went 110 in the 1/4... every other ls1 im finding that went 110 made 345ish rwhp on the dyno
345rwhp with say 15% drive train loss= 405fhp
so maybe their calculation for fhp was correct but they just used a larger drive train loss number?

and also i wouldn't worry to much about dyno numbers, dynos are mainly for tuning and others use it for bragging rights.
