I would like to start a post comparing the dyno graphs of the basic supercharged setups all the way up to custom ones to basic and custom turbocharged engines at similar power levels.

I think it would be a good reference. I'll see if I can find a SC dyno that compares to mine. However the large compressor and log manifold on my car are far from optimum. There will be better optimized systems than mine.

I guess excell graphs are ok?

If this has been done already in a comprehensive thread give me a link and I'll not go to so much work.

Best comparison I could find was the KB 12 PSI IC kit. Nice curves.

Holy **** Brain. You got this covered lulz

I figured he had a few of these laying around. The centrifugal SC's will probably almost always show less TQ at a similar peak HP level because of the mechanical link to engine RPM which is a failboat.

The only ones that will show similar to favorable numbers are the positive displacement SC's and they better be quite efficient. That Kenny Bell unit is very nice.

I have a 1.2L Whipple comparison to the GT2560 dyno ready to upload but I was wondering how many PSI the GT2560 is and what engine size? The Whipple is Chris's SSM car which I am unsure on engine size, but assume 1.8 or 1.9

I'll upload it anyway. I can edit later.

Whipple SC's seem to offer the best of both worlds as far as down low torque and top end power.

Makes me want to keep my whipple and use that... :-)

If I had one I would fix that bracket and use it. ;P
