Trans brake question

63corvette · 05-01-2009, 06:25 PM

I also race a C-5 and it is all in the suspension, converter and launch RPM with my car.
Hughes converter with 6400 stall.
Last year I had to carry .040 to .060 to keep from going red. I ran as high as .090 at one race.
I was using 5400 to 5600 in the low chip depending on adjusted altitude and bringing the stop on at .007.
Rear shocks rebound in the middle and 2 clicks off of full soft on the compression side.
Front shocks in the middle on adjustments.
4 link holes set as Davis set them.
I did have to adjust the right rear preload to get it to go straight on launch from where Davis set it up.
Every car is different as I have friends who use totally different setups.
If someone else does your transmissions and it is a Dedenbear case have you checked the release adjustment on the rear of the case?
Hope maybe some of this helps.
Good Luck with the issue.

The difference is in the release, typically the regular brake uses a spring behind the valve for the release. The pro tree brake uses a fluid release. It also requires a second hole be drilled into the case, so once you go pro brake you can't go back. Pro tree brake requires pushing button to get reverse also.
