That place is where by I live...

The numbers don't look very good...even though mine hasn't been dyno'd I would get in the 280-295 range. What town do you live in, and is the dyno place you were at any good?

I live in Richmond...yeah PAS is a good shop, I'd say (even if they ARE Mustang guys...they've got Saleen's everyplace, I think they're a dealership too)

And as far as the numbers, I figured since GM rated the car at 285, and figuring in the drivetrain loss, 234hp/269tq is pretty dead on. It's stone stock, remember?

These cars actually put down 300-310 FWHP stock. Something is off with your car.. either that or it was built on wednesday

Our cars are RWD....but I'm assuming it's a typo

The numbers are probably dead on for the condition of his car, but I have honestly seen stock 97 Formulas dyno at 265-270 RWHP.

How much did they charge you for 3 runs? Is it auto? How many miles are on it?
