Brought the GN to the track last night...

Only change was a TE-45a turbo. That thing is huge!

I quickly learned the 50# injectors were too small in combinaiton with this turbo. . The injector duty cycle about 50 feet off the line was 108% and the car kept popping at a few points in the run.

The boost last night was 20psi, anything more and it would just pop. The car went almost the same exact MPH when I ran the TA-49 at 25.5psi.

No spectacular ET's to report as I was on and off the throttle when the popping was occuring. It did go 11.80 something @ 117.69mph.

I guess I really need some larger injectors afterall.

Another thing I noticed was the MAF was maxing out at 255gps on the lauch and once when I accidently twisted the bleeder valve a little too quickly! I only have a 30psi gauge so I am not sure how high it actually went, but it buried the gauge for a split second . I may need the Extreme chip which will triple the resolution since mine is only doubled.

Wasn't the best night at the track but any night driving the car home is a good night.
