I would imagine somewhere around ~12.0:1 but it depends upon the setup of the car.

I usually tune to 11.5-11.8:1, that run one of the fuel pumps dropped out and my fuel pressure didn't increase at a 1:1 ratio with boost like its suppose to.

The next run with no other changes the car ran 11.4 through the whole run.

Until I figured out it was the pump it was driving me crazy

Great vid.....autos look so easy ...lol But my question is...why would you even stay in that run with the a/fs that lean the entire run? Lowest it even blipped to was a 13.9 .

trust me if I noticed it I would have let off.

The car was all over the track that night so my eyes never looked down.

People also don't understand how slick Cecil gets on a cool night, keeping the car straight and hitting all your shifts is enough to worry about.

And to tell ya the truth the car was pulling like a mofo, I never would have suspected it was that lean, usually the car will pop and misfire with those a/f ratio's.

I also was manually switching off the nitrous just after the 1-2 shift.

I picked up a tenth in my 330 time doing that over using an rpm switch.

It seems like you have a longer than normal amount of time between when you shift the lever and when the tranny shifts? Cool video nonetheless. :)

Wow Dave I'm impressed, you are the first to notice that.

That was on my old tranny with my Pi4400, after a full season using the T brake my fins layed over and the tranny started to shifting slow.

That night was the first night I started feeling it, it actaully got worse before finally I lost 3rd gear at wot.

I could cruise 3rd gear but as soon as I boosted- it would drop to 2nd.
