I was averaging 9 minutes but after some discussion here I added 15% expo and rather than limit the epa to 75 or 80% throttle (I like it wide open on our home straight) I used the throttle speed limit available on my 3pks to slow down the throttle response and my lap times went down due to less rear wheelspin and better overall control and my run times leapt to 11min average..Driving style can make a big difference though..smooth use of the throttle rather than jerk/brake/jerk/brake style will vastly increase runtime..I have been practising smooth control and have been frankly amazed how much difference it makes..difficult to maintain sometimes under race pressure though..
