High performance Clutch/pressure plate?

[126coupe]

I am in the market for a clutch/pressure plate package for a
901 push syle transaxle. i have used centerforce in the past, but I am looking for more options.

If you had to choose between
Sport round spring disc or Sport solid puck disc what would you choose?

So tim is this a bolt on deal for a 901 Gear Box?
I am very tempted.

[TimT]

Yes bolt on, just specify whether a 6, or 9 bolt crank..

also no slipping the clutch, you will now be pushing or winching your car on the trailer also

Can you elaborate on this? I have winch, but you cant drive it into the trailer?

[TimT]

Well you could drive it into the trailer if your able to to so without slipping the clutch.

These type clutches are like on/off switches. Basically you dump it and go.

Mark, we have used these setups in many race 911/914's with the 901 box its a bolt up using the cable, you have to be sure to set the pedal travel with a positive stop so you do not over stroke the pressure plate. How is your 12 pin distributor working ?

We are at the PRI trade show this week in Orlando and will be back in the shop Monday 12/18, I will be checking my e mail and checking in here if you have a question.

I will call you on Monday, probably will get your clutch package, but would like to chat. The Distrib is working great!
What a difference.

I have the tilton brand clutch that is somewhat similar to this.
These clutches are race only.
you often get the car going by reving it up and dumping the clutch.

there is nothing gentle about these clutches
they are best used in race cars where the majority of the shifting will occur on the track.

literally an on and off switch
expect to kill the car half of the time you are starting from a stop!
(especially if your first gear ratio is an "F" like mine)

I understand the advantage of a light flywheel, but can anyone elaborate on the advantages of the dual disk system, this is a "track only" car.

[TimT]

Powertrain Tech, Tilton etc make these small dia racing clutches in 1,2,3, and 4 disc configutrations.

The greater the # of discs the greater the torque the clutch can hold.

A single disc can hold 250 #/ft of torque, 2 disc = 550 #/ft,
3disc= 800, 4 disc= 1050....

so a single disc would work fine for a smal displacment engine, but you would want to have a buffer or factor of safety, so a 2 disc is typically used.

[Brant]

also, the advantage is that the disk and friction surface is only 5.5 inches in diamater.

its much easier to spin a 5inch flywheel than a 14inch flywheel
its an extreme version of lightening.

but you won't be driving the car onto the trailer or slipping the clutch
that would be a sure way to create a burned out clutch in no time.
the car is either full rolling or full stopped... doubt you could put it onto the trailer comfortably under its own power at 15mph....

thus we push our car by hand
and others winch them on.

This is my package from our host. I drive the car everyday wtih no issues.

Mark,
Allan at Aase will sell you a package. Shoot me an email and i will give you his #. He has custom stuff made up and it works great for the 901's. The prices are excellent.

What has this to do with engine rebuilding?

I am only guessing, but is'nt the flywheel and clutch part of the engine?

[sww914]

Well, when you pull out the engine and transmission and seperate them, it's still stuck to the engine.
I haven't seen a clutch forum here, I think it's appropriate to post in the engine rebuilding forum, but I may be wrong.

If you have to ask that..... You should not be LOOKING in this forum.
