I have not race a727 with a trans brake for a long time so I have no real world current experience with one of todays trannies, my last race car had a glide in it and I would launch it at WOT on the tans brake which was between 5400 up to 5800 RPM depending on the track elevation and D.A., shifted between 7000 up to 7300 RPM, which was 2.0 MPH faster at the same ET confused
On your deal it will depend on what RPM you want to launch the car, testing different ones will help find out what your car likes work scope
It looks like your car should hold up without parts breakage luck grin
