I'm currently running 5.14 gears with a 33" tire going through at 7400rpm running 9.50's at 138-140mph in 1/4. I'm going to use a 180 shot of nitrous and would like to drop the finish line rpm to 7200rpm. I'm thinking of changing to 4.56. What would you guy's reccomend for a gear, And what should it run with the nitrous?

With +180hp NOS it should run 8.80's @155, or quicker if you can hook really good and drop the 60' into the 1.2x range. With the 4.56 gear i would be ~7200rpm @155 so you would be right on with the gear you are thinking of trying. That'll be a ride. Do you have wheelie bars? It'll need em.
