I've read a little about cog belts and it seems for weekend driving they are ok but tension is an issue, they can't be too tight and they have to be frequently checked.
Have you heard about having to cut on the corner of your valve cover for clearance of the supercharger?
hmmm... guess what I've read and Richard has done on virtual dyno's, the best power is below 6500 rpm and the more cubes, the better the power is down low on the revs... At least with the centrifugal blowers, with the roots type blowers, then the power goes up somewhat proprotionately with the revs.... My point is, why rev it if you don't have too....????? As for the cam, superchargers like an entirely different cam then normally aspirated....

As for cutting a valve cover, I would doubt it... Sounds like one more reason to talk with the tech department. I doubt a well engineered kit would require any cutting of valve covers for clearance?????
