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?

Still got the button clutch in my R33 that came with it, but I can tell you my Patrol as seen plenty of high rpm launches... :( Pulled out a stump last weekend, front hubs locked, low range, dropping clutch at about 4.5-5krpms, clutch has never had a problem. My chassis and tow points (and the tyre marks on my driveway) on the other hand....

The cheaper 3ltr Patrol that was released (I think in the late GQ model days?? can't remember) uses a RB30 (no D, T or even E!) that produces about 2 or 3kw less at the flywheel than the RB30E in the VLs. A carby and high torque@low rpm tuning will do that to you though.

I think they would be fine for a stock to mildly tuned Skyline, but I can understand too many high rpm launches could start causing glazing and other problems. The compound used would be designed for low rpm clutching/declutching whilst towing, crawling along 4x4 tracks, etc - fairly tacky for high torque. Never designed for high rpm use.

should not be a problem for high rpm dumps with gtst.

the main difference will be the mesh will happen at lower rpm in a harder fashion.

4wd clutches clamp real hard at all rpm's and is effectively just like dumping them.

Just try driving one - its designed to be either on or off.

So it is not designed to be driven while riding the clutch - thats all.

If you take off with riding the slipping clutch all the time this clutch is not for you.

If you are either going to dump the clutch or let the clutch fully engage before accelerating it is perfect.

It comes down to this - are you able to engage the clutch before accelerating or do you have to slip it to get up to 2000rpm so you can then fully engage.

This is a question I don't know the answer to as I have yet to convert mine from auto.

So someone tell me what rpm do you fully engage the clutch and do you have to let it slip to get up to that speed?

The answer is...

If you can either dump the clutch or let the clutch fully engage before bashing the accelerator on it is perfect.

If you have to let it slip a lot then stay away from 4wd clutch as they get hot real quick due to the compound being designed for low slippage. By hot I mean they smell and get spongy.

One more thing you should consider is the maximum RPM designed for the clutch. The absolute last thing you want is the clutch exceeding its max RPM and exploding, most likely taking the flywheel with it. I've seen what happens when an RB20DET loses its flywheel at 4,000RPM, lets say the car was written off. Both chassis rails cut, smashed gearbox, broken engine block, bits of the flywheel smashed both wheels, bonnet, sliced open the firewall, smashed the windscreen, missed the drivers feet by about 20cm.

In other words, ensure your PRESSURE PLATE is rated to the suitable RPM.

I'll also add another point, if you want a standard clutch to feel better and have less throw from released to full engaged, get a clutch slave cylinder with a smaller bore diameter. What this means is you need to push the pedal less to achieve full release as less fluid will be required in the slave cylinder to throw out the clutch. This also increases the clutch pedal weight so it proves you dont get anything for free in this world :D

got my clutch done on tuesday;

been taking a bit of getting used to as its fully engaged about an inch of the floor;

liking it though, feels way quicker, perhaps the old clutch was slipping more than i though;

Shouldnt a new clutch not engage until it is nealy out? doesnt it mean the clutch is stuffed if it is engaging an inch off the floor?

Just spoke with Gavin Woods AutoTech and they said they will do the exchange and the clutch is suitable, the reason which they do not like doing them is that the fulcum point is different and therefore takes more stuffing around trying to get it fitted, other than that he said the clutch is fine and suitable!

Sorry meant fulcrum point, now I am far from a mechanic, but I _think_ it has to do something with the pedal and how it pushes/pulls on the clutch or where it meets the pedal or something, but I really do not have a clue, just trying to remember who I spoke to (who has done one of these) tried to explain to a dumbass like me:rofl:

Hi guys I need the part number for the  heavy Duty Daiken NISSAN PATROL CLUTCH that you guys are using the part number listed in one of the above posts was only for a standard clutch not a HD.

cheers

same here..

    • This. As for your options - I suggest remote mounting the Nissan sensor further away on a length of steel tube. That tube to have a loop in it to handle vibration, etc etc. You will need to either put a tee and a bleed fitting near the sensor, or crack the fitting at the sensor to bleed it full of oil when you first set it up, otherwise you won't get the line filled. But this is a small problem. Just needs enough access to get it done.
    • The time is always correct. Only the date is wrong. It currently thinks it is January 19. Tomorrow it will say it is January 20. The date and time are ( should be ! ) retrieved from the GPS navigation system.
    • Buy yourself a set of easy outs. See if they will get a good bite in and unthread it.   Very very lucky the whole sender didn't let go while on the track and cost you a motor!
    • Well GTSBoy, prepare yourself further. I did a track day with 1/2 a day prep on Friday, inpromptu. The good news is that I got home, and didn't drive the car into a wall. Everything seemed mostly okay. The car was even a little faster than it was last time. I also got to get some good datalog data too. I also noticed a tiny bit of knock which was (luckily?) recorded. All I know is the knock sensors got recalibrated.... and are notorious for false knock. So I don't know if they are too sensitive, not sensitive enough... or some other third option. But I reduced timing anyway. It wasn't every pull through the session either. Think along the lines of -1 degree of timing for say, three instances while at the top of 4th in a 20 minute all-hot-lap session. Unfortunately at the end of session 2... I noticed a little oil. I borrowed some jack stands and a jack and took a look under there, but as is often the case, messing around with it kinda half cleaned it up, it was not conclusive where it was coming from. I decided to give it another go and see how it was. The amount of oil was maybe one/two small drops. I did another 20 minute session and car went well, and I was just starting to get into it and not be terrified of driving on track. I pulled over and checked in the pits and saw this: This is where I called it, packed up and went home as I live ~20 min from the track with a VERY VERY CLOSE EYE on Oil Pressure on the way home. The volume wasn't much but you never know. I checked it today when I had my own space/tools/time to find out what was going on, wanted to clean it up, run the car and see if any of the fittings from around the oil filter were causing it. I have like.. 5 fittings there, so I suspected one was (hopefully?) the culprit. It became immediately apparent as soon as I looked around more closely. 795d266d-a034-4b8c-89c9-d83860f5d00a.mp4       This is the R34 GTT oil sender connected via an adapter to an oil cooler block I have installed which runs AN lines to my cooler (and back). There's also an oil temp sensor on top.  Just after that video, I attempted to unthread the sensor to see if it's loose/worn and it disintegrated in my hand. So yes. I am glad I noticed that oil because it would appear that complete and utter catastrophic engine failure was about 1 second of engine runtime away. I did try to drill the fitting out, and only succeeded in drilling the middle hole much larger and now there's a... smooth hole in there with what looks like a damn sleeve still incredibly tight in there. Not really sure how to proceed from here. My options: 1) Find someone who can remove the stuck fitting, and use a steel adapter so it won't fatigue? (Female BSPT for the R34 sender to 1/8NPT male - HARD to find). IF it isn't possible to remove - Buy a new block ($320) and have someone tap a new 1/8NPT in the top of it ($????) and hope the steel adapter works better. 2) Buy a new block and give up on the OEM pressure sender for the dash entirely, and use the supplied 1/8 NPT for the oil temp sender. Having the oil pressure read 0 in the dash with the warning lamp will give me a lot of anxiety driving around. I do have the actual GM sensor/sender working, but it needs OBD2 as a gauge. If I'm datalogging I don't actually have a readout of what the gauge is currently displaying. 3) Other? Find a new location for the OEM sender? Though I don't know of anywhere that will work. I also don't know if a steel adapter is actually functionally smart here. It's clearly leveraged itself through vibration of the motor and snapped in half. This doesn't seem like a setup a smart person would replicate given the weight of the OEM sender. Still pretty happy being lucky for once and seeing this at the absolute last moment before bye bye motor in a big way, even if an adapter is apparently 6 weeks+ delivery and I have no way to free the current stuck/potentially destroyed threads in the current oil block.
