I sent my P600b to procharger to go thru. Once it was there I then got to talk to the tech that is in the back rebuilding them. They do have some 3.36 gear sets left and they are going to fit an M1 impellor on it. If you just call in they tell you only 3.05 gear sets are available and no upgrade impellors. By the specs it will take it from 1150CFM to 1400CFM. I'm looking forward to getting it back together and on the dyno-I might have to change from 2 bar to 3 bar MAP!
