There's people making in the high 300's on it. Much better output than the older vortech/jrsc setups. Then again the jrsc was a roots so kinda apples to oranges when you compare them that way. Cool kit, but you fabricate all your own I/C and piping. There is also no way to run power steering or a/c since the supercharger mounts to the old a/c bracket position on the block. I would say that is the biggest downfall when comparing to a turbo besides the actual obvious differences in the setups.

Care to elaborate on how you came to that conclusion?

From what I've heard with the kraftworks sc you are getting power through the whole power band and not like a turbo when it hits peak boost. but like i said it was what i heard so dont quote me 100%

While this is true it's still a centrifugal supercharger and torque is still fairly peaky like a turbocharger setup. Now compare that to a roots like my setup it makes 200 lb/ft of torque from 3k and carries it all the way out to 8k RPMS.

I still do not feel that this is better than a turbocharger setup for many reason. Main reason for this is belt slip which is always an issue. It may be better with the Kraftwerks since they run a serpentine belt instead of a cog v-belt but I would still see that to be an issue at high boost.
Also you have no choice in the matter for running a/c and power steering with this kit

For a strict road race car that needs a fatter lower power band I think this is the best option but for 95% of the population turbo is far cheaper/efficient/better-bang-for-the buck option. Just my .02
