we ran a 10.5 class sat and we were mostly around 5.2-5.6. For reference we run on a large piece of carpet and were running 13-14 second laps. I might start at a 5.9 and temp and gear up accordingly. This was all with an LRP sphere comp, orion 4800, the novak 10.5/4300's with sintered rotors. I wasn't running a fan at all and temps indoors were low
80's. I was running a 32/96 with 57 mm tires and my motor didn't get over 130.
