I dyno'ed on a dyno dynamics....not a dynojet.....at 310 whp approximately 400 crank with JB3 map7, rpi scoops, bmc drop in filter, dinan axle back exhaust and ms109 race fuel.
400 crank hp means you have 23% drivetrain loss and even a car equipped AWD and AT combo wouldn't have that much loss.

Quick question, how did you calculate crank hp? If you got 310 whp then it should be around 356 crank hp if you calculate normal 15% drivetrain loss. No?

the dyno dynamics dynomometer usually calculates approximately 23% Joe@raceprecision or RPIpower can elaborate. I'm just posting the information they gave me during my last dyno
