I know a few guys ported the supercharger themselves...

I was just wondering what you followed for a template, and what hp/torque increase (or decrease) you saw at the dyno?

thanx in advance

 

I used the steig. design. We also port matched the upper inlet to the gasket and used a extrude honed upper intake plenum. Gained a couple of PSI. This was done and installed on a built motor running a #8 lower with the heads done.

 

i did a similar design to the steg. on the outlet. and spent countless hours smoothing out the intake side. then gasket matched the inlet, and the plenum.

no dyno results, and i did this when i put in the new motor, so without swapping the stock one back on, it will be hard to get reliable dyno results.
