did a search and the best thread was about two years old, thinking of adding a transbrake when i rebuild, motor is fairly stock, just head/intake/carb soon cam, but everything else stock 72 455, now i read of people leaving at 5000-5800 etc rpms, does that hurt motor, tranny rear, or does the brake take all abuse?? dont know if i understand how they work, sounds like when i used to punch it in revers, put in neutral and gas it, then drop in drive, LOL :3gears: :3gears: :3gears: but trannys never lasted, may stick with footbrake style, but would like to try and get nice wheels up launches. thanks for the input, john.
In my opinion... And thats just it,an opinion,a transbrake would be kinda overkill and not really useful in your application. I think that if you are a decent footbraker,you would be better off with out the transbrake. Especially with a stock type setup as you say you have.Why not have a little fun and do like I did and install a manual valve body? I went a bit different with my car and installed a manual/reverse pattern shift and a Quarter Stick 2 shifter. Since my wife is going to learn to race with this car,I thought it would be easier to have the gear pattern PRN123.so she will have to just pull it backwards to shift instead of banging it ahead and maybe going from 1st gear to 3rd.Only downside is driving it in town.But if you were considering a brake,you most likely would not be driving on the street all the time.
Transbrake advantages: 1. Allows a launch without the suspension preloaded (makes best use of suspension action) 2. Releases faster than the footbrake 3. Prevents the tendency for the car to creep after staging Disadvantages: 1. Beats the living crap out of the converter, driveshaft, axle & suspension because of the shock. Make sure the converter is built for the application, i.e. anti-baloon plate, otherwise you risk killing the engine with crankshaft loading. 2. Fastest way to heat up the trans...make sure you're running the best trans cooler you can get. The max RPM you can leave at is the actual stall speed of the converter, so if the converter is stock you'll not be getting anywhere near the RPMs you mentioned. You'd need to find a well built aftermarket converter with a stall speed that works best with your combo, and make sure it can handle a transbrake. Devon
