Ran the turbo for about 2 hours last night. First impression is that the motor is smooth, almost like a turbine. Rolling the power on slowly, I was seeing boost by about 5000rpm, and could take it up to about 10 without much trouble. Will have to adjust my wastegate a little more. We had a ZR 900, XC7, and our XC440 snow crosser out for some testing as well. The cat just had reeds and the heads done, and was working really well. I didn't run heads-up with it yet, but from back to back testing my impression was that the RX would easily drive away from the cat. Once the turbo has more time on it and a few of the bugs are worked out, I'll post some race results...
I have one small oil leak to fix, and the IC needs a quick tweak, otherwise things are looking pretty good!
