The V8 Owners Forum -

looks like the new engine (4.6) coupled with the nitrous is to much for the current AP Racing clutch

spoke to Helix today and they recon i need a 6 paddle clutch.

Sorry mate was busy at work to answer, i think they can do different compounds mixed so you get a decent feel, Ad see if if they do a sprung centre plate as well, I think they do|

Yeah Terry said they do a sprung 6 paddle clutch, that is user friendly on the road, but extreme clamping force for track use,

He is ringing me back wednesday with prices and possibly other options,

AP are also ringing me back wednesday with some possible options

I think with the AP version they may require a sacrificial insert for the flywheel, BUT, may not be needed if you have a "Soft" friction material,

anyone recomend any clutches?

7" tripple plate tilton, get a second hand one of ebay from a nascar car. Get some new plates and off you go, bit brutal in heavy traffic, but it wouldn't slip no matter how you abuse it.

Look this is not fair, I am being serious here, they are cheep from the NASCAR teams second hand, they have normally done 1 race before being changed, which with Nascar means a start and about 8 pitstops, total of about 50 gearchanges and they will take serious abuse without slipping. All you have to do is get the right clutch discs for the rover, and they arn't silly money. The only problem with them is that they have very little "feel" when engaging them, and when they bight they bight hard there is no real transition unlsee you force it with the peddle. They are very like a motorcycle clutch to use in that they do not tell you what is going on and when you take your foot off they are instantly engaged if you are not used to them then you end up stalling the engine like a learner .
It is a serious sugestion

Tony,

What AP clutch do you use?
I'm using a CP2394-60 cover & CP2346-4 friction plate with a spec of 339lbs/ft of torque & I've been abusing it since 2005.
This clutch was recommended by AP after asking a lot of questions. I found them very helpful.

May be worth giving them a call on 024 76639595 & asking them for advice.
Regards Ged

So now you shall be known as COOOOOOOOOOOOOOOOps

thats what im currently using Ged,
they have now advised me to go with a CP2394-46 cover and CP4216-4 plate, this will give 350lbs/ft but a stronger clamping force,
if i use CP4196-5 which is a fixed center 6 paddle gives me a spec of 522lbft

Cheers for that info Tony. I'll file it away for future use.

I have a V8 development spec Helix on my Griff. It's not slipped (yet) with 350ftlbs. I dare say you are looking for a little more than this...

I would look at something like a twin plate Superclutch & concentric release bearing scheme if the Helix clutch ceased to be up to the job.

im waiting to hear back from Helix,
tried calling them today as was told monday i would be called first thing wednesday morning with options, and when i called today was told i was going to be called straight back, but nothing happened,
