My gears seem extremely long and they really seem to be making my car seem a little sluggish. I think I either have 2.73's or 3.08's? At about 107MPH I was at 5k in 3rd gear...I'm thinkin their 2.73??
What kind of 1/4 mile improvement should I see with 3.55's or 3.73's? Current one is 12.7@107. Will low 12's be easily attainable? I'm leaning towards the 3.55's because I'm planning a turbo setup in the near future. Heres the current setup:
90 GT 5spd 98K miles, powerdyne s/c w/ 9lb pulley(no boost gauge) 30lb injectors, 75mm maf, 190lph pump, bassani longtube with 3" bassani x pipe, and flowmaster 40 series mufflers with stock catback piping running on 10" m't slicks without a tune
