Got some chit done today, modified the SC. Now it didn't come out like a mpx but I think the flow has been significantly increased. I'll let the pictures tell the story...
first we tack in small pieces of metal scuff up the area then epoxy gets poured in. On the sides we used quick steel epoxy puddy.
marking it up for cutting.
rough cut.
the inside you can see the old port job.
let the porting begin!
inside the blower, you can clearly see how much material was removed. Broke through to the epoxy. I would have gone even further/deeper but.... I would have broken through the epoxy!
before the surfacing... we used a long file to get it flat worked very well, I use silicone as a gasket anyway so no worries.
you can see how much bigger the opening is now. I just cut the intake flange down and ported it to match.
So what do you think? Not bad for a few hours of work. And the epoxy will stay put it's sandwiched between the case and intake flange with plenty of ribbing to grab onto.
I'm also going from a 1.9 to a 2.3" pulley. Already have it on the shelf. That's a 2.9 drive ratio from the old 3.4 ratio.
I have a 2.7" pulley but it won't spin the blower fast enough (at least I think it wont).
