Has anybody ever had their engine on a dyo and then had the car dynoed and figured out a geminis drivetrain losses?
I know its between 15-30%, but any closer would be good.

| Most common number Ive seen is 25%. So whatever the rwhp figure is, the flywheel kw is the same eg. 140rwhp=140kw at the flywheel. |

But that'd be 104.47kw @ the wheels with 140 ponies (nearly 40%).
** just being picky! **
Most older cars the figure is around 1/3 lost through the drivetrain. |
