Is anyone going to come up with an actual model or part no??

I have a friend who owns a specialist 4x4 workshop and he carries at least half a dozen different clutches for the various year and models of the Patrol, and, they are not interchangeable.

the power limit would be like the amount of torque a patrol can throw out, plus its in a 2 ton vehicle. But I still wouldn't take it past the other daiken exedy H/D limits which are rated @ 450hp - I reckon they are a bit overrated powerwise.

Well how come the part number for the Daiken HD for a Skyline is R5208HD...

I have spoken to both Daiken distributors and to Coventry Auto, and have recieved the following information.

"The Nissan Patrol Clutch kit will fit, it has a higher rated pressure plate than the standard Skyline pressure plate. Noting this the pressure plate is rated so as to match the torque characteristics of the Patrol engine, despite sharing similar flywheels, clutches are designed with different applications in mind."

and this

"The Skyline HD clutch has an uprated clutch plate compared to the Patrol Clutch plate. The clamping pressure is similar however the the combination of varying clutch and pressure plates are designed to take either big torque low rpm, big torque high rpm or any combination in between."

or

"We do not recommend the fitment of a Patrol Clutch to a skyline and vice cersa, they are designed for different purposes and the clutch compound is different for both kits"

Don't kill the messanger, this is the info I recieved.

just thought i'd chuck in my 2 cents, even though the two clutches would be made of different compounds the low down grip and clamp that the patrol harnesses for distribution thru 4 wheels SHOULD be a godsend for hard as fu** launches, i suspect what daiken have in mind when doing their extremely expensive r&d is how fast is the clutch going to spin with what amount of torque thru the rev range and what sort of pressure can be applied to said clutch at different points. BUT i still reckon that it is worth a try, i mean what is 5-600 bucks in the scheme of things if you are going to find cool shit that that can be cross fitted, my clutch is starting to slip too and the patrol clutch is going straight in, why not. least i know it wont fall apart on me when racing me some commode-whores! Peace.

You really think that Daikin chose a clutch plate material for Patrols that will withstand hard launches? How many people do you see doing high rpm launches in their Patrols?

Just because it fits, doesn't necessarily mean that it's suited to the application, is what Daikin is trying to say.

I wouldn't know what to think. There are several people here with Patrol clutches now. To you guys - How many hard launches has the clutch withstood so far?

what i was saying that is with a 2+ ton vehicle running a 4wd drivetrain, made to take the extreme pressure that mud, sand offroad etc would put on the clutch and p/plate that hard launches should be a sinch, i realise that the rpm is different with launching a line and a patrol, but it is made for a pretty heavy duty application.

this has all been extremely interesting, i feel so conflicted. i will now consider a patrol clutch. one thing no one mentioned is the torque that a 4WD has. id have to agree that if a patrol clutch can take the low end toque, it should handle high rpm dumpage from a relativly light car, for a little bit anyway.

    • How dare you sell your unreliable Skyline and buy a reliable, Toyota/Yamaha car with a strong gearbox, torsen LSD and Toyota reliability. At least you won't need to worry about oil pumps, big catch can, oil restrictors, blowing off power steering belts, sheering off 3rd gear, failing ABS relays/pumps, etc.
    • Hope you aren't too sore after that one, might take a day or 2 to notice yet and I guess it is a loooooong drive home. On the bright side, tube frame front end is a thing at superlap, right?

    • The chart of front pressure to rear pressure (with one being on the x axis and the other being on the y axis) is not a straight line on a typical proportioning valve. At lower pressures there is a straight line with one slope, and at higher pressures that changes to a lower slope. That creates a bend in the line at that pressure, called the knee point. If you do not change the proportionng as the pressure gets higher, you will suffer excessive pressure (at one end of the car or the other, depending on which way you look at the proportioning action) and then get lockups at that end. The HFM BM57, from my memory of previous discussions, is based on the BM57 from a different car (to a Skyline), with a different requirement for the location of the knee point and the distribution of pressure front to rear, and so is not a good choice for an upgrade on a Skyline. Here's a couple of links to some old posts, one from here, one from elsewhere. A lot of it pertains to adjustable prop valves, but the idea is the same. There are plenty of discussions on here about this issue from al the many years of people wanting a cheap/accessible option. https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/ https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/  
    • Yeah dunno why johhny posted that here with no context, just post on FB/insta bro where he put it up?  Laine had an off at T4 during Thurs prac, he's ok, car is less than perfect, they are done for the weekend, he can fill in the rest. Bando also binned it like 100m up the road.
