1) Gearing doesn't make horsepower.

2) There is very little difference between 3.31 and 3.55 gears.

I know this. Bit gearing changes how well the power/torque from the motor is transferred to the ground, this giving a higher reading. It accounts for drivetrain lose. That's why a weak car with 4.10a can hook like hell, but still fall on its face up top.

Give me some credit, Steve. :p

Gearing simply just moves the powerband around. If a car doesn't make enough horsepower to use a steep gear, it's going to fall on it's face like you are saying, however it's not going to manipulate a dyno as you think it will.

As for 3.31 vs 3.55, there is almost no difference between the two gears at all. I've got a 3.31 car, you and I could race and we'd be shifting at the same times providing traction is not an issue. :)

hp can vary from dyno to dyno and day to day. Some cars are just freaks and some just simply dont make good power.. I have seen the new 5.0's make as low as 310 hp and as high as 405 hp to the tires bone stock!!

The only way to get a 100% true hp number is to pull the motor and measure hp at the crank. There are so many things that can affect hp numbers...

Just need bigger injectors.

Womack, you really need to have your tuner fatten up the fuel from 3.5 to 5k or you're going to have some problems

That car has probably been driven 100 miles in the last 2 years. It just sits. :(

I can fix that. :)

STD #'s were 436HP 411TQ for comparison purposes.

It got sold for an auto.
latest dyno on current car with stock #'s for comparision

cats are off now and im running a different tune.

Nice! He has always been a little leary of that tune i think.

Kevin, I will get with you after I get that beast up and running. It has that weird fuel pressure drop between shifts, that we will need to tune out. I can't remember what you told me we needed to do, or what tuning products I need to get.
I'm just waiting for Holly to finish nursing school, then i'm back in the game.

Yeahhhhh buddy. It's probably the PPRV and needs a real tune from Kevin. :)

Can't wait to post my new numbers here in a couple of weeks.
