I added 50/50 water meth system to cool down the IAT and get a little more octane. This enabled me to run some more timing (2-3 degrees), fight off high IAT2, and also resulted in a little less fuel demand on the stock injectors. I'm currently at <4.8 ms injector pulse width, >70 psi low side, and > 3400 psi high side - all good things. I'm hoping to swap to a 2650 this year. I will likely be safely at the limit fuel wise, hopefully (would like to hear feedback from other experienced 2650 users responding to this thread).

You'll need one of the A10 guys in here to comment about the auto transmission, I have no experience here on this platform. I'm M6 and even the stock clutch was holding with this power, I now have McLeod RTX though.

3400 psi sounds a bit high. How long have you been running. It like that?

I was always under the impression that ideal DI fuel pressures should not exceed 2,9xx psi. At least on this application. Of course I don't claim myself to be an expert on DI subject matter by any means whatsoever so maybe someone else will chime in regarding that.

Whatever the case is, it sounds like you have a hell of a build!
