Default Re: Dedenbear T Stop Timer

Dustin

do you know what the RPM on the stop is? Do you shift on time or RPM.I have found that between 3900 and 4200 rpm's on the stop is optimal. If you have too high of stop rpm the car can accelerate while on the stop and get close to the shift point RPM if the car jumps off the stop and goes directly into high gear you will LOSE a bunch of ET. Sometimes the car will even shift while on the stop. (even worse). If the stop rpm is too low the boosters in the carburator will float and dump fuel (not good)

If you dont know how to check the Stop stall here is what you do.
1) pull the launch chip from the 2step
2) engage the stop (pull the lines off the air feed) so the stop blades are closed
3) start the car and put it in first gear
4) press the trans brake button
5) mat the gas and watch the tach (for about 1-2 sec)
that is your stop stall within 100-200 rpm

Check it out & let us know
