ZR-1 Clutch

[no go nova]

Has anybody use the new ZR-1 clutch with there T-56 Magnum?

Requires a 9 bolt crank or an expensive flywheel to make it work. Katech and Lingenfelter both have the whole package but by the time you are done you could buy a cenerforce dyad.

Stielow runs them on his cars and I believe he had a spacer in between the trans and the bellhousing for added clearance.

I see so not worth the hassle

I see so not worth the hassle

I am running one but we are just in the mock up phase and building a custom crossmember. Here is an extensive build thread on installing a ZR1 clutch and a T56 Magnum. The build thread is step by step and the guy even gives all the part numbers. Excellent info.

I've got a 69 Camaro project going with an LS9, ZR1 clutch, and T56 Magnum. D&D Performance makes a spacer to allow the QuickTime bellhousing to work with the ZR1 clutch, LS1 slave, and Magnum. It works great.

As an aside, I just put a ZR1 clutch in my Z06. It's an awesome piece. Easy on the leg and rated for 700+ horsepower with an adult driver.

John, what flywheel did you use? LSAs are 8 bolt cranks, right?

Or will the stock LSA flywheel accept the ZR1 clutch as it is already setup dual disc? If that is the case, then that is a no brain decision to run the ZR1 clutch.

[parsonsj]

On the Z06, I used the Lingenfelter steel flywheel. On the 69 Camaro, my stuff is all LS9 (I fixed the post above): engine, flywheel, clutch.

I think the LSA and LS9 crank bolt pattern is the same, but I'm not certain.

I'm using the LSA clutch with a T56 Mag. I had to use spacers to adjust the play in the Hyd throw out bearing but it can handle tons of power and abuse. I'm told by D3 that these can handle up to 1000hp based on their racing experience with these.

Using a spacer is one solution. I also saw a build on V8TV where they replaced the Magnum front plate with a bellhousing frof the CTSV TR6060. The CTSV has the front transmission plate integrated with the bellhousing and this gives the necessary spacing for the ZR1 clutch.

What is the cost of the LS9 clutch? With all the talk of spacers, different bell housing ect. Would it be worthwhile in most cases? As opposed to just going to an application-specific aftermarket twin disc?

[no go nova]

I'm with you Gnon18s is this really worth the hassle?

[parsonsj]

Hassle? It would be nice if an aftermarket clutch just bolted into place without having to know all of this information, but that's a rare event in my experience. YMMV.

John, one word, DYAD

They bolt in to just about every LS powered car (6 bolt flywheel) the factory ever made, one part number. In an aftermarket situation, t56 magnum, stock bellhousing and stock 02 fbody hydraulics. Works great, no spacers, shims, or drama. Ships with all hardware needed (ARP), flywheel, discs and pressure plate and is super easy to put together. Also comes with a "dyno sheet", the last one I put in averaged 1,384 lbft of breakaway torque.....I have no idea what that means exactly but interpreted it as "I can't hurt it"

Again, if you are in a situation where the LS9 clutch makes sense, it's a winner for sure, but if you are dealing with a hopped up ls motor with a 6 bolt flywheel I can't see doing it any other way. It's the best thing since IImuch fuel vents!! ;-)

[parsonsj]

Donny, I'm listening. Expect a call when I get to my next project.

[CarlC]

I have the LS7 clutch in mine and it's like an OE clutch should be. The only other clutch that comes close is the DYAD. In Shipka's car I can't tell the difference in the clutches between his and mine.

Donny does this combo work with a quick time Bell? looking for a flywheel., clutch, throwout packages that work with little to know hassle, for t56 Mag to an LS3/480 and need to purchase this week

this? http://www.summitracing.com/parts/ct...make/chevrolet plus which bearing? I am using stock Fbody slave Cyl

this maybe? http://www.summitracing.com/parts/til-60-6101/overview/

[dontlifttoshift]

I don't know for sure as i haven't done it. I would think if the quick time bell is a replacement for a stock bell in a 98-02 camaro then it is a slam dunk with the factory slave cylinder.

I don't think that particular Tilton slave will work with the T56.

Just a follow-up for those who are interested the LSX/A conversion flywheels. They are now in stock at Fidanza.

The part number to order and weight information for the new aluminum flywheel is as follows:

Fidanza part number - 198891 - LSX/A conversion to ZR1 twin disc

PRODUCT weight is 11.70 lbs

They are doing a 6 bolt + 9 bolt version as well as even a version using this oem c6 zr1 clutch for the new LT engine conversions. I don't know the part numbers as I have an 8 bolt LSX engine. The weight would be the same.

Good info. That bellhousing is a bargain. Anyone with a T56 Magnum should be doing this swap because extra room in the bellhousing is always desirable.
