i got a question fellas, ive been lookin at a few superchargers, most recently a 6-71 weiand street setup. problem is that they dont answer my Q's on the site. it says that on a stock engine with 8-9 compression that the supercharger produces about 50% more power at 6 lbs. but says nothing about built engines. mine has forged internals with a steel crank and 9.5 to 1 comp. it says at 9.5 to 1 i can only run 4-5 lbs on a stock engine. but seeing as how mine is not stock, does that mean i can run a lil more? also im going from a 62 cc head to a 72 cc head with bigger int. and exh. valves, shouldnt this drop my comp ratio?

thanks for all your help in advance.
