Timing is fairly conservative for E85.

I work with a guy that used to be an electrical engineer. I told him about this turbo and he came up with a real simple circuit to control a servo with a pwm signal and move it based on voltage (or map pressure). He also said that he can set endpoints and control the hold voltage or map signal. My turbo should be here today so we are going to tear into the stepper motor that controls the VGT and will see what kind of input it requres. We might just switch to running it with a servo and call it a day though. Will keep you posted.

I think water/methanol injection would really be a sweet addition to the HMT monster of the decade. I ran a Snow Boostcooler on my Saturn and liked the system. Nice stuff. It dropped IAT temps significantly and really freaked people out when the hood was up. "What the hell is all THIS ----?"

Re: 95 TSI AWD Project VGT Holset no 56k
can someone get me some more measurements on this turbo? ive been looking at doing this for a lloonngg time (since 04 when i worked on my first 6.0 powerstroke). i have a 6.0 turbo off of a burnt truck so it needs a serious rebuild. but since i can get one of these so cheap i wanna see if i can fit one of these things inbetween everything in the hatch crapper. if you could whats the length from end of the turbine to end of the compressor, the farthest accross part of the compressor and turbine housing and the widest part of the center section. id really appriciate it! thanks a lot
