06supercharged

Took out the 430 gears put in 390 gears .Went back to the track and the car ran 11.50 The car even seems faster with the gear change. My 60 foot improved to . I was at budds creek and ran 11.50 @ 119.1760foot was 1.65and 11.57@119.8960 foot 1.69 and the third run was 11.62 @118.22 60foot was1.69. I m real happy with the car MY mph went down from 122. I would have thought the 430 gears would have been better .

did you get the procharger installed yet?

Nice. Yeah 4.30's are a bit much. Hoping my 4.10's will be ok with my procharger.

Why did you go with 4.30's in the first place with FI? Guess you should change your sig now

If I had to guess, the 4.30s spun up too fast, and the 3.90s allow the blower to build boost a little longer in each gear/ higher boost pressure for longer times FTW

I'm dealing with that in my car. I have 4.10's and first gear is so fast I'm looking at putting 3.73's or 3.90's.
