Gear Experts/Drag Race Only: What Gear Size? Did a search, but the gears I am asking about are not on any charts. This is a 2000 Trans Am for drag racing only. Primarily raced in the 1/8 mile, but must make it through the 1/4 mile for National races. What gear could I move up to? Could I use more gear?
This is what I have now:
Moser Full Spool, 4.56 gears
4000 stall converter
Rear Tires: 28X10.5X15 slicks
*Right now the car barely hits 3rd gear in the 1/8, and shifts fine through 4th in the 1/4 mile.

Based on your info/data
4.88s' would put you at just over 6300 thru the 1/4 traps.
5.14s' would put you at between 6600 and 6700.
the above is strickly theoretical mechanical.
in the real world with the 4.88s' your 1st to 2nd shift shift would occur at a shorter distance down the track and this also applies to the 2nd to 3rd shift and to the 3rd to 4th shift so it would end up being in 4th for a longer section of track and even the 4.88s' might put you past 6600 thru the 1/4 traps.
the 4.88s' would make you a better 1/8 miler and 1/4 miler(if it would end up within your 6600 limit).
the 5.14s' would be wicked(if you can get traction) for the 1/8 but too high numerically for the 1/4.
It's impossible? to have a car set up for both situations as the optimum for one situation is not the optimum for the other situation
