Setting up Cal Tracs

[Ian Hill]

i have not tried a trans brake in the 68, but have used them in the past. From what caltrack told me the tighter the bar, the harder the launch. This being said, if i was doing what you are, i would call them and ask. they are great.

From what i have heard...the higher the rpm on the brake, the softer the hit on the converter. obviously your would be putting the engine closer to the max torque of the engine so that statement may make no sense to someone that is struggling with wheel spin. i would start with adding wheelie bars, then try the 2 step at 2200 and 4800 and see what happens. i would think 2800 to 3200 rpm, wheelie bars set to allow a good 2 feet of space under the front end, 30x 9 light weight radials by Hoosier set to 16-19psi (i run 18 foot braking, but have pumped thm up to 25 without issue on a great track) (also my car is 3000 lbs and has a 500hp crate engine, so use your own descresion).
