It was an interesting night - and somewhat disappointing. For some reason (and I'm thinking tune), the car is retarding timing and making the rev limiter come about 800rpms sooner than it should. The rev limiter is set to 6300, but tonight the highest I saw was 5800, and the lowest was 5500.
This made it all the more difficult because I was forced to put the car in 5th to cross the line.
My first run was terrible. I don't even want to say what it was. I spun way too much off the line, and once it hit the rev limiter way early, I gave up and coasted across the line in neutral.
The second run was better, a 13.1, but still terrible.
I talked to a local tuning guy who's with Dynospeed, and he's thinking that my intake temps are too high. The PO has a very safe tune that he put on the car, and down here it's much warmer and more humid, so I really think the car needs a new tune done down here in TN to adjust to the climate change. Also, having no intercooler doesn't help either. So, I'm looking into a meth kit.
So, I left a bag of ice on the intake for about 30 minutes, then on the supercharger for about 30 minutes as well. Here's what happened:
While I was warming up the tires, there was no rev limit at all. Letting off the foot brake and goosing it sent the rpms to about 6800. But, by the time the light went green, it went back to red lining early. It was a decent launch (2.0 60'), but the red line in 4th was still about 110mph, when it should be 123mph. So, using fifth gear for the later portion of the track, I manage to run a 12.2.
I'm not happy at all with that time. So, I know I need a new tune. I could use a meth kit and some 3.55's as well (PO hit the top if 4th before he crossed the line at 123mph). What are y'all's thoughts?
