Would this be one of the better Road Race Specific 6 Speeds?

[68protouring454]

ty is going to have both transmissions in his cars. He has talked about both synchronized transmissions and face plated dog ring transmissions in his posts

t-56's hold up plenty well with good syncros and steel shift forks and a few other goodies, we have had one in a time trial car for 3-4 years and its just getting tired, and its behind a 686hp, 580 tq 427ls
we run that to 7200-7400, gear changes are precise.
are you not sure what you will be doing, you mention road race and street use in the same sentence?
Liberty can face plate/dog ring 1-4 and leave 5 and 6th synchronized, which just may be the ticket for your hi revving engine.

For the record, the Keisler R&T T-56 ty was referring to is designed to be shifted clutchless. It goes without saying you wouldn't want to attempt that with a transmission with traditional synchros.

I also prefer to change brake rotors and pads instead of trannies and clutches.

I also have a ZF6 in my c4 corvette track only car and it shifts very nicely but I only use it up to about 6500 rpms. They are just too big to fit in a 70 Mustang trans tunnel, need too much work to adapt and cost a fortune to rebuild.

Anyway - for high rpm use with syncros what works well? I have a POS Richmond 5-spd that needs to go in the trash and want something that works well with a 600 hp 7800 rpm dry sump motor on the road courses. No drag racing is in it's future.

funcars:

Sorry it took a while to get back to you on this. Here (I hope) are the things that will help answer your questions.

Here is the information on the Transmission:

http://www.keislerauto.com/recent-ne...k-6-speed.html

Take a look at the 6 pages here that speak about the transmission. I think it will answer a lot of your questions. This transmission can be used on the street with a clutch or without. The only time a clutch HAS to be used is for launching the car, or stopping.

Take a look at this and let me know what you think based on your background. By the way, I appreciate your comments and input.

Thanks,

Ty O'Neal

Ty,
Thanks for the info. Maybe a face-plated trans is something to consider - as long as there isn't too much routine maintenance.

Funcars:

At least according to Shafi, these transmissions are supposedly pretty tough.

I had originally bought it for the Camaro, but I'm going to stick it in the Grand Sport for now (Since it will be done first) and get the hang of it. I should be at a point with the Camaro sometime next year, (Hopefully) where I can pull it from the Corvette and replace it with a T-56 Magnum. Then run the hell out of it in the Camaro.

I'm going to start a thread and see if any other people on this forum have been using it.

Take care,

Ty
