I didnt want to ask this question but I have alot of people asking me about how much HP my 99 is putting out.. can any one give me an rough estimate..

Its an 01 motor
Edelbrock 62mm Tb
3" exhaust
Flowmasters
X pipe
Steeda CAI

I know they are label at 320.. is that RWHP or at the flywheel??

any help would be great..
thanks
Jim

 

all motors are rated at the flywheel unless specifically stated, its flywheel, at the wheels im not exactly sure about the 01s... probably around 300 give or take a bit

 

ive always been told that from the crank to the wheels is a 20% loss in hp give or take, so not sure if its true but that s what i go by.

 

With those mods I would say you are probably in the 280's at the wheels. With a tune you'd pick up another 10-15 hp.

 

Thanks.. thats kinda what i figured..

 

I'm putting down 307-308 (Can't remember which) at the wheels with the mods I have listed...

 

That seems a little high for just CAI, tune and pulleys. Either that is one hell of a tune or you have a factory freak.

 

It seemed a little high to me too, but I've got a dyno sheet back home (At college now) that's 307-308hp and 313-314tq. It is a dyno tune, so that might help a bit, but I know that the guy who was doing it knows his stuff and did a great job on it.

 

What kind of dyno was it? Are those numbers SAE, STD or uncorrected? Not trying to seem like an *** but the numbers don't look right. In my experience when N/A the 96-98 and 99/01 4v's are tuned to the max their HP numbers will be higher than the torque or they'll be the same because of the intake cams. Those look more like Aluminator or Mach 1 numbers, but still high for the mods.

 

OP go get it dyno tuned, you'll see numbers and wake it up alittle bit.
