Ever thought of shifting without the clutch? On a track this has some advantages (especially the non-bendy type of track) due to the increased speed you can upshift with. But it comes at a big cost if you mess up (grind those gears).

The nicest solution outside of a new dual-clutch setup is a sequential gearbox, much like a motorcycle has. But sequentials cost on the order of 20K+. Here is a link to a sequential if you don't know what they are (Sequential Tranny). If you have never ridden a motorcycle and shifted it without the clutch then perhaps the value of this will be lost on you. Suffice it to say that in competition it is a requirement or the other guys will toast you on starts (when I raced motocross we rarely used the clutch).

Well now there is a new solution for a far more resonable (albeit still pricey) amount. Check out this link. It talks specifically about the T-56 tranny but he also makes references to Mustangs so I don't know if he can upgrade a TR3650: Keisler Racing Tranny.

I can't say its on the top of my wish list but none the less very cool.

I'd like a Jerico please.

I was just reading Drive to Win yesterday by Caroll Smith and if I remember correctly, he said its slower to clutchless shift with a synchronized tranny. The benefits would be the ability to left foot brake though.

I dont know if its slower but it is likely to ruin a syncromesh tranny unless you get it perfect everytime. The sequential and the Keisler have no synchros, they have much, much stronger gears with fewer teeth, often called a 'crash' box or 'dog' box. No need to clutch them at all, hence much faster shifts. And the left foot braking while downshifting is icing on the cake.

Jerico is basically the same thing. It would be a great option also...if I only had that kind of money to throw at a tranny, LOL.

ive read that on dog box trannies you have to rebuild them a lot more often, i was looking into them for my 240sx, and they really have no practical gain on a street car, or any car that sees street use because of NVH.

I've got an sv1000 as my second bike and know what you mean about clutchless shifting on that. I can't say i'd really want to do it in my car though. I had an old bronco II that had a leaky clutch slave cylinder and had to do it becuase it ran out of fluid. I don't do much racing either.
