Calculating HP at the crank

Going by (SAE corrected) dynojet numbers, which have very little variance from shop to shop, and data I've acquired from half a dozen VQ37HR's... ***Dynojet derived whp and drivetrain loss***

So, if you make 300 whp on a dynojet with SAE correction, it makes (probably) somewhere around 359 - 363 bhp. Mothra108 likes this. __________________ Enjoy it. Destroy it.
