Sorry for the delayed response,
3,000 Miles on the build, Still zero issues. Only thing I've had to replace was a piece of the Snow Meth kit because it was leaking slightly. The turbo is louder and spools quicker than ever, motor runs great. I really beat on it and its holding up fine. Just put some Nitto 555RII's on the back and it grips like crazy! Maybe my motor is a freak or its the perfect combo of E85 and Methanol but there have been zero issues,
No track info yet on it, Colorado tracks don't open until late April or May.
Whooped up on a couple Nitrous and blown c6 z06's, GTR's, 911 turbo, and 20 little 4 banger Evo's and Sti's (thats all you can find in CO). I'll upload some vids from the GoPro here soon

Hello guys. Sorry were busy in the Shop making Horsepower 
Just saw the car yesterday for a Check up after 1 month of fun, also talked about a upgraded clutch to go with. Setup currently has 1000 miles and everything still looks good. The Rear Mount Oil Less Turbo is now starting to "break in" it's providing slightly quicker boost, and also has that nice whistle at idle that people love.
To answer some questions.
The fuel system is a
Walbro 255L per hour In tank (very reliable and supports up to 600RWHP on it's own.)
Bosch 340L per hour External -10 from Tank to -6 Feed (helps prevent external pump cavitation)
Twin -6 Feed to Edelbrock Style LS1 Rails
Single -6 Return
Boost reference Regulator
100lb Injectors
The above System is similar to the A&A Fuel system, but using aftermarket rails instead of the T fitting to the stock rails.
Injector duty cycle is in the 65% to 70% range. We perhaps go to 900 to 950 RWHP with these Injectors On E85 at this altitude before an injector upgrade is needed, the Fuel pumps and system should be good to 1000 on E85 and 1100 on Gas.
We are running 100% meth with largest single jet Snow provides. Meth Starts spraying at 5psi. IAT's we have seen on the Dyno WITHOUT Meth Spraying are 160 to 170 Deg at 15psi. (not too bad considering we see 180+ deg from many centrifugal Blowers with the use of a Intercooler at these boost levels.
With Meth spraying IAT's remain in the 100 to 125 Area. On the Street IAT's are even cooler. If Meth Fails the tune will pull timing for safety.
Thanks for all the great comments guys !!! Now just need to get the owner to the track so we can have more videos to watch !
