Anyone ever use one of these.. Looking to buy a clutch and need some info\opinions on twin disc's.. I did a search and cant find anything about tilton.. I guess maybe cause its made in the USA.. most cars in japan are using OS Giken..

 

OK.. I guess Tilton does not make a twin disc clutch for the RX7.. I guess that could be the reason..

 

I have a Tilton twin disc in my car. Unorthodox made the flywheel but the pressure plate, discs, and a new slave cylinder are Tilton. I wouldn't recomend it for a street driver. There is little or no slipping the clutch from a start. For the money I would go with an carbon/ carbon clutch. or evev a Exedy milti disc.

 

i wouldnt go with that clutch!!

 

I WOULDNT USE a Tilton ever again!!! It only lasted a couple of months driving it on the street, the damm disks are THIN!

 

really.. what kind of material was the disc made off that it only lasted a few months.. I hear that if you use cerametallic or organic, something other then carbon you can slip it somewhat..

 

anyone of you guys know what parts you need to do the conversion from pull type to push type..

 

Tilton twin disc clutches are what I call a digital clutch. It's either on or off. If you try and run it in between on and off it burns up. A friend toasted his GTA's clutch (V8 tube frame race car) just driving it into the trailer. If you need a serious clutch you can get just about all you could possibly need with a 4 puck metallic disc under a factory pressure plate. Just make sure you budget for a flywheel and pressure plate every time you change the disc.

Bottom line is small multi-disc clutches are for race cars.

 

Aren't they all RACE clutches?
Did Tilton tell you it was okay to run it on the street?

Im just looking for something that will hold the power im making 500+ rwhp. But I dont want to hate driving the car since its only used on the street. I have driven a 6 puck with a stock pressure plate on my awd dsm and thought that was fine. If it feels like that then thats perfect for me. and I dont want to be burning up disc's every other month either.

 

TED,
When I ran that clutch, the year was 1994...we were thinking that it would be similar to OS clutches...we tought wrong!

 

Tilton makes one, however it is available only thru MAZDACOMP. I just received my QuarterMaster 5.5" Twin disc and its off with the rotating assembley being balanced

 

Tilton does not make a kit for the rx7.. you have to buy a universal version and then custom fit it to your car..

 

There is no need for a kit because the Tilton universal components work with stock RX-7 transmissions. As mentioned earlier, Mazda Comp sells all the components.

 

Taylor Race engeneering Inc. out of Plano Tx. makes flywheels that accecpt the Tilton 7 1/4 Twin ot Triple disk clutch setups.
They also will sell You the complete package: Fly,Clutch, Disks for any spline, and hardware.
The flywheel they offer is for 225 mm. bell housings, & starter mount position.
Can be used w/ either a Turbo II bell housing or FD bell housing.
I colaboreted with them on this project, as a result of the Rx3 bell housing becoming extinct.
Most of the common "race" Tilton or QM type clutch & flywheel setups out there are for the small flywheel & small Rx3 bellhousing (215 mm.)
When considering purchasing, make sure you specify the diameter of the Fly.
The clutch is Universal, only the splines for the disks change, depending on the input shaft of the box been used.
I have used THE SAME Twin 7 1/4 Tilton clutch on 3 consecutive Daytona 24 Hr. races with out a glitch. They are literally indestructible.
As for use on the street ? I would say, as long as you have a VERY LOW 1st. gear, like a 3.3 + or better, then longevity sould not be a problem.
With a higher, 1st gear, (something in the 2'ss) then slipage from a standstill becomes an issue.
As for the material, it is Sintered Iron, it is very durable, and handles a great deal of heat, it also has a very hi coeficient of friction, the hotter it gets, the more it grabs. The material is sprayed on to the driven disks, that why they are so thin, they also have to be so thin in order to FIT into the small package.
It is engeneered that way in order to achive a low "Moment of Inertia"

 

Tilton make a Rally spec clutch in the normal material, the pads are much thicker and allot more durable that the circuit based sprayed disks, these are tolerable onthe street and very good wearing clutches. I ran one personaly for 6 years in my RX7.

I currently run a Tilton 3 plate Carbon/Carbon unit which is the ultimate clutch money can buy, perfect drivability with unparralled slipability and long life & power capability (1800bhp !)................ but the cost, dont ask If you need to ask then you cant afford it applies.

If you need some data or advise on the rally spec Tilton clutches feel free to PM me and I can provide you with part no's of what I used to run.

 

please post part #'s i'm interested, i was going to get the act until i ran a search on the thread
thanks

 

Here are the part #'s I have, they are rally spec items.

66-302UGG - pressure plate assembly
64-185-7-AA-30 - Disc pack

 

would this bolt on to stock flywheel? thanks for the part numbers

 

No, any decent machine shop can make you a custom flywheel for $200~300USD or there abouts.

 

Fidanza makes flywheels with the correct bolt pattern for tilton clutches.

 

I have a friend with this clutch in his Supra. It cost him $4000!!!! Please tell me you guys arn't paying this kind of money for a clutch.....There has to be something comperable, but cheaper. What about the Exedy Twin disc? I know thats about $1400

 

Seriously...for 500rwhp and a street car on street tires, even the Exedy Hyper Single would be enough!

 

My set up with custom flywheel, Tilton throwout bearing, and clutch unit cost about $3500USD @ my price....

Its a "bit" but you have to remember there is no other engineering solution (regardless of cost), also there is a factor of about 10 times greater life when using one of these !, the cost spent is quickly recouped with time so its not that expensive.

And at the end of the day after you have worn it out you ship it back to Tilton and for a very small fee you get back a clutch with %100 life in it ! Its a super example of advanced engineering that wins in performance/function/life & cost over time........ thats why I had no question in handing over the amount required for quality parts.

 

I paid $1999 for my setup , Flywheel ,discs, pressure plate, Hydraulic T/O. At the time there wasn't many choices. The main reason i went with tilton is the availibity of parts in the us, and all i would need to do is swap discs if I was to swap out the tranny.
