yea turbos get higher HP numbers, but the newer superchargers that companies like Pro-charger and Rotex are making have almost the equivalent in boost pressure with no turbo lag, so they are more street friendly. i have a camaro performers mag thats got an 87 iroc that the guy put a 406 sb with twin gt75's on and a fat th400, makes a supposed 1150 hp before his 150 shot of nos. talk about a track queen.

 

yea im not arguin that the newer superchargers arent good... but with the new technoligies with anti-lag (studder boxes) twin turbos are hard to beat.
