i raced my full mod tonight in my d8 and it was off the hook. was running it rich in my first heats i had tq but lost it . so before the main edd and me leaned it out a little and omg it was screaming and i was running the 7.5 carb insert 8 min main and still had 1/4 tank with plenty more room to lean out so should be getting around 10 minutes run times easly when leaned out.
