ok ill be pushing 300-325 at the flywheel. what would that be at the rear wheels?

 

auto or standard? for auto figure ~20% loss, standard ~15-18%

 

its an auto. drive shaft and rear are the same..trany has been built up with a shift kit if that makes a differance

 

240-260rwhp

 

Yeah, around 20% loss with the auto. So 240-260 rwhp like stated seems right on the money to me.

 

crap thats what i was thinkin ... i want MORE!!

 

is that a ok amount?? i mean i want a fast car that will kick the crap out of the ricers around here, and the occasional mustang.. i was hoping to get 13.5's by then end of the summer... but that kinda HP at the wheels wont do it will it?

 

it really depends on the trans and rear end your using. also depends on whether your driveshaft is steel or aluminum and how large your rear tires are as well as rim material. with aluminum wheels, aluminum driveshaft, 700R4, and 7 5/8 rear with synthetic fluid it's possible to get the number down around 12 to 14 percent. i've seen a camaro tubbed with a 9 inch and turbo 400 that dyno'd just over 500 at the engine and 357 at the tires and another camaro that dyno'd 410 hp at the engine and 364 at the tires. one test i've seen even show's a difference in gearing differently for rwhp gains. it's not all something that can be estimated and for no reason at all should be. there are too many variables. at 20 percent, the drivetrain has to be pretty terrible to have that much draw.

 

I think it ought to!

 

No that isn't good for mid 13s. With a very good 60 foot you may be able to break into the 13s, though.

 

You will need 400hp ( not sure if it is flywheel or rw) to make mid 13's or better with good gears.
