Injectors

Does anyone know what whp a zr1 with stock injectors are good for?
Typically you will see about an 18 % loss between the flywheel and the rear wheels.... I would venture a 638 HP rated engine will be approx. 540 HP at the wheels on a dynojet unit...
 
Duty cycle is pretty much tapped out around the 700 mark (RWHP). Anything higher and I would look at upgrading them.
 

I had the car dyno’d a few months back it’s bone stock and made 596 to the wheels
 
7% loss from engine to the rear wheels... Never heard that before.... Maybe you got the special 700 hp stock engine.... I heard they put one in every 500 ZR1's made just for the halibut... j/k.... That's an amazing number....
