not some thing you should worry about unless there is a problem or you are searching for numbers......
a dyno / rolling road should only realy be used to check the set up is working correctly and safely..........
a 32% loss dose sound a bit excessive from a 250 bhp motor ????
mate, 70hp loss at 450hp makes 15.5% loss which is quite low for a 4WD car.. are you sure about the numbers? 10-15% loss is for FWD cars...
