I never saw a reply from the guys that blew up there AE28's in there SC8's. I am half way through my second gallon and I went through my motor and everything looks fine. The only thing I have had too change is the clutch shoes and I went to an 17 tooth pinion because the engine seemed to flatten out in the long straits at the track I have been running at and it seems a lot better and still pulls hard on the bottom end.
