With a Pro Tree transbrake I am leaving at 3800 RPM with .050-.060 in the box, so no problem cutting a light.

With these kinds of numbers, I think you must be running a BB. ?

Thank you for the advice guys, seems a majority is to keep the C4 - this does save me some money to spend elsewhere.

I have several Super Street customers who run 3 speed transmissions because their car is a heavy weight .
If it was my car ,I'd keep the C4.

If you dont mind me asking, how are you approaching the Stop set-up with the 3 speeds? Are you running t stop in 1st gear or 2nd gear? How low in the run is the stop coming on for them?

Have a friend who may dabble in this who runs a heavy S/P car (SBC) with a Flying toilet injection system and a 3 speed. Runs 10.60's in 1/4 at 123. We dont run 3 speeds s I'm curious what others are doing with them and the stop?

Thanks,

Andrew
