Flywheel figures

Had my car run at AET Turbo's hub dyno and it made an average of 309.5 atw (peak was 311), what would this equate to at the flywheel?

Graph attached

They do not measure anything at flywheel, as i quried the exact samething so even the torque is a the at the wheels.

I'd guess you'd lose about 15% to the hub as you normally loose about 20-25% to the wheel which is much larger than the hub.

Not 100% sure though.

Was that with the MD195 or the 20G?

by having Torque at the flywheel, you can work out HP, search in google for the HP formula

I think it would be

HP= (TQ x RPM) / 5252

if your case

HP= (290.8 x 5514) / 5252

HP= 305.3

there...
