Speed Metal, we just started shipping these on Monday so most shops have probably only gotten them in the last couple of days. So if anyone has seen them it would have been in the hands of some of our sponsored drivers when we were developing them over the last 6 months or so. Guys like Kortz, Wheeler, Gosch, Korn etc. Plus it's a buggy motor and this is more of an on-road focused forum. Give the S Grid a shot. In a nutshell though it has more power over the entire range than the old B7 and actually gets better fuel economy. It's a from the ground up new design. Long stroke motor, new porting, new crank that has been lightened, epoxy ramped and tungsten slugged. New carb, new turbo head button etc. etc. etc.
