To better clarify, I meant that its hard to get the car moving from a stop in first gear with the 2.66 ratio compared to the 2.87 ratio I had while driving on the street. The new trans has never seen the track. The 6th gear is also pretty useless below 75mph.
When I launched on the old setup, It had to be 3500rpm or above. Below that would bog the car down. I've never paid attention to the boost at the line. Too many things to concentrate on when I'm at the line. My car likes to break a lot, I've only got 7 passes on the car since I built the new motor with the turbo. Its going to take a lot more practice for me to pay attention to things like boost on the launch. An MSD 6AL2 will be in my future, so that 2 step will help me out when the time comes.
Power is in the sig. I've done stuff since I dyno'd those #s so they should be a little higher, but not much. I've never weighed the car, but its basically a stock weight '95GT with some addons. I've removed some stuff, but added stuff in the process. For instance I've tossed all the smog stuff, alum heads instead of iron, moved battery to trunk, and lighter seats. However, add on subframes, roll bar, turbo setup, heavier trans, torque arm, panhard bar, larger radiator, etc. I think I've added more weight than I've removed. Plus I weigh about 225, so I figure with me in it the car is weighing in the 3500-3600 range. My shift light is set at 6500rpm so thats where I would prefer to trap, but my rev limiter is a 6900rpm pill.
I'd love to run the 3.89 to make the car a little more responsive and make 6th gear more useable on the highway, but I'm worried about sacrificing boost and running out of steam before I reach the end of the 1/4.
