whats your engine combo?

Dino Dino Bambino · Jun 8, 2009

Great rear wheel numbers if it's a 302 but if your tranny is a T5, the flywheel numbers will be more like 367/390. I'd be very happy with those.

did you have any octane booster in the gas like NOS?

nice numbers

SMOKEDYA · Jun 8, 2009

S&B Are you being sarcastic? I was running just 92 pump gas.Bullitt95 i have a 3550 you divide your rear wheel number by .8 and thats your crank numbers. So on that note i made a mathematical mistake and it's 398HP/423TQ at the crank. FOOT2DFLOOR it's a 351 40 over low compression H/C/I peace

I've always heard people say 15% drivetrain loss for most 5 speeds so that would put you at 366hp/390tq at the crank.

90lxcoupe · Jun 9, 2009

seems like pretty weak numbers no offense man, but with that much cubes and a good cyl head it should be making better power

5.0Torx · Jun 9, 2009

highly unlikely that you have 20% driveline loss.

Got a graph?

351 40 over with AFR 185s i gotta agree with 90lxcoupe no offense but those numbers are low, the good news john is u ur car has alot more potential with that setup

KamiKaziDK · Jun 9, 2009

Anyone else think 13.63 af is a little high? I would think around 12.5 would be much better

SMOKEDYA · Jun 10, 2009

Guy's dont sweat it and i know the truth hurts! I was expecting closer to 400/400 when i built this. BUT with 8:1 compression and only 499 lift.What do you expect trust me i was f'n pissed off when i took it in for the tune and seen those numbers so now it's turbo time! peace

yeah those numbers are a bit low(NOW) but once that little snail finds its way in there, its going to be a monster!!! Im in the middle of a similar setup but looking for 10:1 compression. Just cant seem to find the money fast enough to get it done=-)

Thats the plan if i hit 600 at the wheels i'd be happy for now. I'm also (since it will be apart) thinking of going to a roller cam? peace

Then your dyno numbers aren't so good after all but there's plenty of potential there. The low compression certainly won't help and your engine could do with running richer (12.5-13.0 NA, 11.5-12.0 FI) for best power. Sounds like you've got a good basis for a forced induction set-up so that would be a good plan. Combined with a better cam that 358 should rock.
