OK here's our latest with the new motor, and I'll give as much details so nobody blows it out of porportion.
We have 3/4 gallons (Byron's 30%) on the motor, still not completely loosened up but close, also till running the breakin shim, we run a losi 2.0 with titium turn buckles, and screws, 47 th spur gear, 13 th bell, 6m carb restricter, 9901 pipe,and 41021 header, Impact soft tires, we ran at the Nitro Pit which is where the Challenge was, and same layout, medium bit, rough ,out door track,
after both 7 min qual's we had about 1/4 tank left, end of qual temp was 210 both rounds,
weather was really windy, and probably 60's
plenty of power, not too punchy, but fairly smooth,
my son's driving style is smooth and consistent, won both qual rnds and set TQ, but set screw on cv came loose on 2nd lap of main, and we called it quits.
Overall a great motor, run time I can't say until its completly loosend up, but has plenty of power and run time, and yes, I'd by another one
