What gears are these.....

[StealBlueZ]

I took the vdrive out to find out the ratio that I have, inspect and clean up a bit. These are the #Â’s on the gear:
40T (40 teeth)
1.29 ????
3.93 ????
Right now my motor turns about 6250-6500 thru the lights at 102 mph. IÂ’m guessing itÂ’s near 700-750 horses. Would there be room for improvement by changing gears and the current motor?

Count the teeth on each gear and let us know and you'll get and exact ratio back:)

ITS SO EASY.....I'VE SEEN GUYS STARING AT THOSE #'S AND STILL COULDNT TELL ME WHAT GEAR THEY WERE HOLDING IN THERE HAND. IT'S KINDA LIKE READING THE D.O.T. # ON A TIRE.
