i dont wanna jump in on this late but if i read and caught up correctly didnt you say you had the engine dynoed? i can see the 132 to there and not at the wheels with the few mods you do have. without the drive train loss you numbers are gonna be a little higher... but correct me if i misread

I think you are correct, he got 132.4 bhp (brake horsepower).
Even with a 15% drivetrain loss (super conservative), that's close to 113 whp. with bolt-ons AND tuning, this is certainly possible. at a 10% loss, it's 119 whp, that is a more "interesting" result.

I concur that 132 at the crank doesn't seem all that hard-to-achieve. I'm pushing 110-115 at the wheels with strictly bolt-on stuff (intake, pulley, exhaust, wheels)
At the same time, this all sounds very haphazard and unscientific. I'd love to believe it, but you don't back it up with any pics or dyno sheets. When/how did you hook-up your engine to a dyno? Are you sure this isn't an "estimated HP" thing? Also, aren't you getting any CEL's from your modified intake/throttle body? Seriously, post a pic of this intake bypass for us to check-out.

i understand, but my idea of replacing the con-rod is with "lighter" con-rod material, if it is lighter, i think it will affect the lower power band. that's why when i change to the lighter rod, i will also change the camshafts. what do you think?

it seems that we have a misunderstanding about the dyno method. as i mentioned before, it was on engine. for the next step i will use on the wheel

Reducing conrod weight will have only a very marginal effect on the reciprocating mass. In other words, I severely doubt if you could tell the difference while driving it.

How did you connect the dyno to the engine?
