Timing on two step

We run a pro mod car with a psi d case on it 2500lbs 5.00 rear gear 1.60 first gear crower 10.7 clutch hoosier tires having problems with hi wheel speed at .25 sec out to 1.0 sec out how much timing should we pull at the hit leaving on two step and how fast should we put back in going to race this weekend so would like any input someone may have
thanks

Looks like way to much first gear for a screw blown deal. I would try something in the 1.4to 1.46 range with the 5.0 rear. Good luck.

 

with our cs1 fine spline we can not get that low of a first gear in a three speed lowest they make is 1.25 gear sets which would make a 1.56 first right now we have a 1.28 and a 1.25 = 1.6 first any thoughts on timing from anyone
thanks

thanks

Well you can take out 12*15 deg if you are at 22*22 now and ramp them in 1 sec.. But you should also gear a gear eliminator shaft from lenco and start playing with 2 speed only 1.45 * 1.38 or close

have you run the two speed and did you have to run a lock up clutch
thanks

You can run the two speed, thats the way I have mine now. and doesnt have to have a lockup.
or put a 4.56 rear in it.
