RE: Dyno #'s
346 hp and 353 torque
ORIGINAL: FullAuto
The 353rwhp seems to really make me question a few things. The really good stock shortblock FTI combos are making in the 330-340rwhp range. That's with a custom cam, through a 5 speed and on a Dynojet. I have serious doubts the car could honestly make this much power with an E cam, EFI and stock compression. I would lean heavily to a miscalibrated dyno. A Mustang Dyno should read 10% lower and that's being very conservative. So does everyone believe this is a 380+rwhp Dynojet car?
I would recommend putting the car on the nearest Dynojet for a second opinion. If it seems too good to be true, it usually is. I'm not saying it's not possible as I do not know what all was actually involved in the rebuild, but if it were my car, I'd want another opinion just to verify or discredit.

RE: Dyno #'s
I'd be happy with those numbers too. I'm not flying the BS flag yet. It just seems a little odd to me that you're making roughly 15-20% more power (if comparing potential Dynojet numbers) than some of the top stock shortblock cars (I know yours is rebuilt but it's my understanding you are still using stock pistons at stock compression). And you're making these numbers with an E cam!!! If you are happy with your numbers, don't worry about what anyone else says. We don't race dynos. Take it to the track. Those are the only numbers that count. I was just saying if it were my car, I'd want a second opinion. I would be very reluctant to believe those numbers if based on the information I've seen about your combo.

i think the easiest (and most fun
) way to solve this, is to just get to the track and see what she does. then get back to us and let us kno how it goes. anybody agree?

High HP does not always equal low ETs, Example. Our 88 GT has 460 RWHP (I have posted dyno curve) but with street tires it just spins the entire track giving it slower times than lower HP cars that are not spinning.
