Just thought I would pass this info along.

Apparently fits the stock case. Info Blatantly stolen from LS1tech.

Awesome!!!! Assuming it works in the T56 magnum cases.

That's pretty sweet! That is if you've got an extra 20K laying around.

There's also a guy on PT working on this. I think he uses something similar to a Mastershift (?) acutuator to shift. Not yet a fan of that system.

Interesting! But if I'm being honest, I don't fully understand what a sequential shifter does. Do you still push in your clutch?

I just got my six shooter sequential t56 from MTI. You don't use the clutch for shifting. Essentially, it's like a motorcycle trans. Use the clutch to get started and that's it. You don't have to lift the accelerator on up shifts and it auto blips the throttle on downshifts.

The trans is going into a race car though, not a street car. I'm not sure the expense would be worth it for a street car but for a race car, it is actually pretty cheap. Purpose built sequential racing transmissions like an EMCO can cost $40k-$60k.

It would be interesting to see how much improvement it would have in lap times vs more adding more horsepower.

Greg here's my opinion - If I'm driving on the street do I really need a clutchless sequential shift? Yeah it'd be cool but not sure I could justify it. OTOH if I'm racing I want the fastest, easiest and most reliable I can get. If I'm in a vette I'm almost limited to the MTI option. Other conventional motor/trans set ups have the ability to do clutchless, sequential shifts. Then it goes back to cost, reliability and fitment. Not sure a T56 set up meets that criteria yet...

Horsepower isn't always your friend on the racetrack. I'd rather have a well handling 400+ HP race car than an ill handling 600+ HP race car.

With that being said, the car that my trans is going into weighs 2050lbs with 585rwhp.

On a road course you can shift 20 times per lap or more depending on the car and track. If you can pick up .1 second per shift, that equals 2+ seconds per lap, which is usually the difference between the front runners and mid packers.

Also, if you're spending $20k+ on your trans, the odds are pretty good you aren't lacking in the motor department :)

I agree about not needing clutchless sequential trans for street use, unless someone come sup with one for less than $10k. There is no question that they are cool but no real reason to spend the money unless you are racing in my opinion.

But there are definitely other options for Vette owners. EMCO makes a direct replacement that is awesome but its quite a bit more expensive than the MTI trans.

Hopefully the MTI trans will hold up as I believe I have one of the first customer trans out there but since my car is so much lighter than a Vette, it won't have as much stress on it.

Exactly, I was coming from a perspective of the money spent on the trans may improve one's lap times more than additional hp. Especially if it aides braking performance as well. :thumbsup:

PS - nice hp/wt ratio. Better than a 250cc shifter kart with a 170 lb. adult in it. :D

I totally agree. I've been racing for a long time but I'm still an amateur, not a pro and getting perfect braking while heel/toe downshifting is very difficult to do lap after lap. Not having to worry about the clutch or blipping the throttle on downshifts is the beauty of the sequential.

If you're ever in Northern California, you're welcome to take a few laps in the car once its done and sorted out, which should be in 6 weeks or so. :trophy-1302:

Yowzers! Very generous of you. :thumbsup: Are you a T-Hiller?

[patoke]

No problem. Racing is one big family anyway. T-Hill sometimes but I live in the bay area so Sears Point is closer and one of my favorite tracks.

Do you mind me asking how much the complete set-up from MTI goes for?

[patoke]

It is about $23k to $25k I think. I'm not 100% sure what his actual list price is as I bought it along with a built differential.

Um... Pat... hello?! :D

I left you a message the other day... you get it? Call me this week... wanna see what you got cookin.

[patoke]

Dave, when did you call?? I don't remember getting the message. I'm around all week so we can hook up at the shop for a beer one afternoon if your around.

You'll like these new projects I got going plus I have all the old stuff still. I'm going to run out of room soon.

How is your car coming along? Have you gotten to the point of getting the flared fenders yet?
