I want to thank Ken for taking time out of his [busy] weekends the last two weekends for assisting me in rebuilding and porting my supercharger.
We rebuilt almost the entire sc from the bottom up. That includes almost all bearings (rotor bearings we couldn't replace), seal, and coupler. Upon dissasembly we saw that the rear (needle) bearings were completely shot. It looked like they got very hot and discolored the case slightly around them. And there was significant play in the sc. Now there is none at all.
I think the port job is a pretty good one. Basically what we did was use an MP II as a template for the outlet. It is very close to that except that we rounded the angles more than MP does. The inlet received special attention. I'm not looking for anything extreme (yet) so we opened to inlet up to 4 1/4" x 1 5/8" (it's a '95 supercharger) and matched the inlet plenum accordingly. We also smoothed all the angled edges in the inlet itself to increase flow. Overall I think that the porting was relatively minor compared to some on this site. But I think that it will prove very effective. I'm optimisticly hoping for a 25-30 rwhp pickup. That is over a stock '92 supercharger.
I will have pictures in a few days.
Again, Thank you Ken for you help and letting me use your tools!
