Well I finally got those things in there. First thoughts: THey are just about the right amount of gear for the car without loosing drivabilty. The 4.10's are pretty geary, adn the 4.30's are nuts for extended highway use.
I worked extra hard on getting these gears in teh pumpkin. I spent a LOT of time making sure the ring and pinion were in there perfect. Including reshimming the pinion. Looks like it paid off, I have absolutly no vibration that I can feel so far. I had it up to around 100 or so.
Performance? Well there was some stupid Chrysler day at the track today, instead of the normal test and tune, so I did nto get any official track times. I did some more g-tech times, and here is what I got.
N/A 0-60
5.55
5.50
5.39
80 shot and low bottle 0-60
5.03
4.90
4.93
there is ABSOLUTLY no wheel spin at all with the trac loc and these drag radials. 1-2 shift is freaky, almost feels like something is going ot break it hits so hard. The EEC has not learned that the gears are in there yet. IT hits the rev limiter by itself on the 1-2 sometimes. One I get that stupid Chip in there that will cure that problem as well.
The car is a definate any time any where 13 second n/a car.
I am thinking that I will hit a 12.90 with the gears and the 80, and a 12.70 with a 100. Hopefully my 60 ft times will drop to the 1.9's now.
