MP81's Supercharged L61 Build
Those are some nice pics. I didn't realize it was painted that nicely. Hopefully the paint job holds up. That seems to be the modular pulley setup.
Let's get er on and see what happens.

Got the new one on...MUCH better.
Just waiting on a tune now - and I gotta figure how to seal my MAP sensor better...
Rotors on the old supercharger (even marks on the round faces...)

It was ported when I bought it.
I noticed the Stage 2 pulley was kinda loose on the old supercharger, but I don't believe that to be the source of the noise...different sound when I moved it.

i just ported mine yesterday...but damn, i didnt go that much, the outlet is fine the way it is stock. a tad bit off is ok, i ported mine by maybe .5mm and polished it smooth instead of it being casted

Will do.
I definitely still hear a little bit of noise in the cabin, but I'm beginning to think that this is just normal, due to the solid design. It's so much quieter though...

Lets see, so I went out and datalogged for Vince. Still running pretty lean everywhere, but that's to be expected with the different pulley and all.
I get a tiny bit of blower whine too, the cork gasket seems to be working decently for the MAP.

No problem on the cork gasket solution, lol, j/k

Yeah, the only time I hear it really is for a quick second when transferring from idle to movement, basically...like 1100 rpm it has a resonance, but that seems normal...
When we talked I wrote down 11.5 to 12.5, but there as a lot of information, so I must have misunderstood. Sorry!
That isn't too bad at all then. You're good.
