Twin Disk cons and pros!

[talon187]

Ok im geting a twin disk i wondering if theres any bad things about them with being driven on the street. or in general. this car will see no more then 30miles a week if that and once winter comes it wont see the road untill next spring. i may go with a huge turbo over the winter im not sure yet. the reason im buying is because i got the deal of a life time thanks for input guys

I have not gotten the chance to experience a twin disk for myself as of yet but I will be in a few weeks. From what I was told (from the shop selling it to me and yes they have installed several and use them in their vehicles), is that they are not the most fun for a daily driver. I have heard the noises from these first hand, and can say that it would be annoying to me if I had to deal with it every day.

I have a PTT twin in my awd and it is noisey. The majority of the noise is on decel and kinda loud. I have a regular mitsu slave and the clutch is like an on off switch with the engagement point, but you get used to it. People recommend using an Isuzu trooper slave which you can search for info on that, the isuzu slave allows for more engagement window from what I hear.
Some of the things I like about the clutch is that I can actually shift my car( IE the clutch disengages unlike my act.) It takes a lot less pedal effort (again 2600 act) The clutch seems lighter than my old setup. Also knowing the clutch wil pretty much handle anything you can throw at it power wise and it is rebuildable.

If you have any secific questions I may be able to help you out.

I have driven an evoIX with a Tilton multi plate clutch and I see no reason not to drive it on the street. That car has 28,xxx miles on it and that clutch has been in it for all but 36 of those miles. It just got a rebuild. The car makes 647whp with a 35r on 37psi.

i heard they were rough on the transmission do you guys know? i drove a awd talon that went 10.3 with 26psi on a dd 35r i did notice the noise but not over the external pump that was 10x louder and i noitced the pedal was nice and light just little rding it so i didnt stall

Thanks Pat! This link says more than enough in favor of using a multi-disk clutch in a high-HP car.

If you cannot handle a little noise or less streetability, lower your horsepower goals and keep it streetable.

If you have other questions pertaining to the Quartermaster twin disk clutch and your setup, please feel free to PM me with your questions and I will be happy to help you out in your decisions.

Good luck!

twicks your a god!!! you mat not have the highes hp dsm out there, but your awesome for the fact that you seem willing as hell to share any knowledge that you know! Thank you!

 

[twicks69]

I appreciate the very kind comments! I just want the experiences to be known to everyone out there so that they make a more informed decision, and are able to save themselves the headaches of spending alot of extra money making different combinations until they get it right. It usually ends up that when you "know better", you usually go to a different vehicle altogether.

My goal is to only serve the DSM community the best first-hand experience that I can give; give them options on what to do; and give constructive criticizm so that they can better understand what it takes to reach their goals.

The 4G63 platform is extremely capable, but we must understand what it takes through experience to keep the drivetrain together under such massive abuse from the AWD system. It is expensive to go fast, but even more expensive to build a drivetrain that can handle the amount of abuse that the AWD setup sees, and last for any given amount of time.

Clutches and Transmissions are the most destroyed parts on a DSM. If I can help a person out by giving them sound advice on a certain clutch or transmission component that can end up saving them hundreds or thousands of dollars in the long run, it only makes me feel better that someone has learned from the advice that they were given.

Good luck!

I have the Quarter master Twin disk in my car. I would say that the clutch would be ok for a daily driver. The only down fall I have found is that the clutch is extremly "grabby". It is a bit harder to launch the car due to its on off characteristic. You cant really slip this clutch. However it will hold ANYTHING you can throw at it. You get over the noise in no time. When it is disengaged the plates chatter a bit, and when engaging it tends to sound like a belt squeeling. Other than that, once you get over the launching, the clutch is great

What seems to be the best performing twin disk for the money? I know there are a couple that are comonly used. The big two I hear about are the PTT and the Quarter Master. WHich do most of the big hp guys use and like better?

 

[DoyoFCT]

Quartermaster seems to be the more popular one, but I don't think the PTT is much different. I don't think you can go wrong with either one. I heard awhile back that they were pretty much the same clutch or used to be because quartermaster bought parts directly from PTT? not sure how true that is.

 

[JayRolla]

My buddy is running one and only con is that it does make a lot of sound. He broke two half shafts from dropping the clutch too hard, because it does grab hard!!! But for the 10000rpm smooth shifting its capable of its well worth it. Not to mention it will handle what ever you through at it.

I know it has been said but using the isuzu slave is the way to go. I run a dd ptt twin and did so with the stock 2g slave for a while before swapping in the isuzu. The slaves are night and day drivability wise.

Yeah I would def go with the isuzu slave mod. This is going to be a dogbox style trans so I would want to make it as easy as possible with engaging even though it will mainly only see the track.

What year and model Isuzu slave cylinder?

The Quarter Master and the PTT were both designed by the same person just at different times. When he started his own company (PTT) he redesigned the clutch so no modifications were needed on the clutch fork for clearance.

Soo the PTT is more install friendly?

All you have to do to fit the QM setup is to grind down the clutch fork a tiny bit, and use Automatic Flex Plate bolts instead of Flywheel bolts with the PTT flywheel that both companies use with their kits. Really, it is not that hard.

Dont those automatic bolts bottom out in the crank, some drilling and taping of the crank may be needed.

Edit: Nevermind thats when using the auto flex plate.

My PTT flywheel needed the shorter bolts to work properly.
