The 70 on there now has a .68 hotside now but I was going to swap out to a .96 to see how that works out as well. I have a 2v car already done and the .68 spools up fairly slow but I did have some exhaust leaks. I think the 4v car will be a different story though
If you google master power 810047-096 you can see the specs but this would be most of them:
.72ar compressor, 101.7 air inlet, 66 outlet, 76 ind wheel, 103 exducer, 55 trim and turbine is 64.5 ind wheel, 74 exd wheel, 76 trim, 10 blade
