I was thinking of putting 373's back in the mystic in place of the 410's. I drag race all the time. The car has a kennebell blower with 10 psi. It spins the drag radials pretty hard in first and a little in second. I think I may have too much gear. Any thoughts or comments would be greatly appreciated.

You just need a good pair of slicks. But if you want to get rid of the 4.10's let me know.

I only put 4:10's in because I never plan to superchage this car. If I had planned to, I'd have gone with 3:90's or 3:73's.

4.10's arguably are the worst gear for the 4V. It makes you shift into 4th right at the end of the 1/4 mile removing you from the powerband and thus losing momentum.

I'd say run either 3.73's or 4.30's. Being s/c'd I'd say 3.73's.

When did you move out of Statesboro? I guess that explains the fact that I never see you around town.

Thanks for the input guys. I think I may try the 373's. Hey white98svt, I think you are confusing me with the other racinjason with the mystic. As far as I know he is still there!

I have a 99 Cobra with a Novi 1000 running 8 lbs. of boost. I currently have 3.73 gears in the car, but I have already bought 4.10's to put in instead. The 3.73's work great on the street, much better than the stock gears, but the car still doesn't wind up as quick as I'd like it to. With either gear and boost, traction is going to be an issue. I use Nitto drag radials, and currently have no problems spinning them in first or second. At the strip, I have to slip the clutch a lot to get a decent launch without blowing the tires off or breaking a halfshaft.
Look at it this way. If you can do the work yourseklf, it will only cost you a couple of hundred dollars to find out which one you like better. That is cheap in comparison to what you've already invested in the blower alone. If you can wait about a month, I plan to switch mine out right after the Norwalk FFW where I will be racing my truck. I will be able to give you a first hand evaluation of what I think of the two gear choices then.;)
