I just had the pleasure of showing my daughter for her graduation project from A to Z on how to port the supercharger inlet/outlet (and the other supporting components around it- intake plenum/return plenum/etc..). We worked on this for a 20 hour marathon, and we are both very worn out from this.
We took the SC out on it's first WOT journey with the ported sc, and I was kinda dissapointed with the seemingly lack of power increase- i could not feel the difference. in fact it felt like it lost some low end power. I do realize that porting a gen 1 is not going to feel like a 94/95 or s-port swap, but i know i should feel something.
But then i remembered from reading the mp3/s-port comparison posts here that if you increase the blower's ability to flow by porting it, you are not going to necessarily see a difference unless you spin it faster to bring it into it's slightly higher rpm operating efficiency range.
Has anyone tried or experienced using a 15% OD pulley setup (10% jackshaft/5% blower) on a gen 1 max ported blower setup? Or do you think i'm better off by having a custom OD pulley made, for say a 13% overdrive without killing horsepower from excessive heat on the top end too much? i have a 10% od on it now.
i have stock heads,cam, and IC so i know there's not going to be a massive huge gain in top end power to get here.
anyone? thanks-
