Swapping the rear pullies on a 112?

Can you do it? It looks like you there might be enough clearance and it should get you a lb or two without dropping to a smaller front pulley. has anyone done it?

FWIW its a CTS-V setup. Im thinking if I can get leave the main shaft pulley the same and either get another one so its 1 to 1 or maybe a slightly smaller one. looks like itll take some grinding on the cover and lower section to actually flip them...

Yes you can do it. A corvette guy did it, but sent it to Magnuson to have it done. He just changed to a set of cogs. That's what you should look into!

I dont think we need cogs just yet but it would allow for a smaller pulley on the rotor without ever worrying about slipage... who makes it? any sponsors here?

What psi are you running now? I know MTI puts smaller pulleys on their kit to up the boost.

We saw 5lbs once... With the cam and the exhaust its just not building enough boost. I'd like to see 8lbs out of it.
