Howdy fellas, I'm looking for some advice and opinions on a clutch upgrade as I have been researching and it seems that most are either for lesser power or I cannot get any solid information for ie: price, best place to buy, etc. So basically the car is making 300rwkw and the clutch is slipping really bad(even now that it's in rwd), the car is also now rolling in gear with the clutch in.

Now the tricky decision that we could use some experienced advice with is that the turbo's on the car are capable of over 500kw/700ps/690hp and it's only the lack of internals keeping it at 300 for now. The internals are planned within the next year god willing but may get put off for another due to some other things coming up. From what I have been reading a twin plate seems to be a minimum requirement for the current power to take the abuse and there seems to be a few options here but it also seems that twins are on the limit of the planned upgrades after the clutch and a triple may be on the cards.

I'm kinda stumped though as I am pretty sure i read that Jim Berry can make single or twin-plate setups(can't remember which) to handle 500kw and vaguely remember a couple of other mentions about NPC and others. I also expect numerous other parts will break after fitting a new clutch from others' experiences here, i'm just hoping that the clutch will not be on that list for a long time even with the future power upgrades in the next year or two.

Thanks guys, that's quite reassuring Piggaz. Have apparently been quoted 2700 for a HKS twin jobby, don't even know if that's installation included. Where in Sydney or the Central Coast(located) would be a good place to start for good pricing and service/help etc?

if you're not going to be making silly numbers a NPC Clutch is fine, they use a larger pressure plate so you don't need to upgrade your pivot and/or your slave.

Doug from NPC tells me a 10" Carbotic clutch will hold 400 rwkWs without issue (that's what I'm using now on a stock powered R33 LOL)

My pedal feel is like a stock clutch, but however bites like a munted raver.

    • Because people who want that are buying euros. The people with the money to buy the aftermarket heads and blocks aren’t interested in efficiency or making -7 power, they’re making well over 1,000hp and pretty much only drive them at full throttle  best way to way make money is know your customer base and what they want and don’t spend money making things they don’t want. 
    • It's not, but it does feel like a bit of a missed opportunity regardless. For example, what if the cylinder head was redesigned to fit a GDI fuel system? It's worth like two full points of compression ratio when looking at modern GDI turbo vs PFI turbo. I'm pretty reliably surprised at how much less turbo it takes to make similar power out of a modern engine vs something like an RB26. Something with roughly the same dimensions as a -7 on an S55 is making absolutely silly power numbers compared to an RB26. I know there's a ton of power loss from things like high tension rings, high viscosity oil, clutch fan, AWD standby loss, etc but it's something like 700 whp in an F80 M3 vs 400 whp in an R33 GTR. The stock TF035HL4W turbos in an F80 M3 are really rather dinky little things and that's enough to get 400 whp at 18 psi. This just seems unwise no? I thought the general approach is if you aren't knock limited the MFB50 should be held constant through the RPM range. So more timing with RPM, but less timing with more cylinder filling. A VE-based table should accordingly inverse the VE curve of the engine.
    • I've seen tunes from big name workshops with cars making in excess of 700kW and one thing that stood out to me, is that noone is bothering with torque management. Everyone is throwing in as much timing as the motor can take for a pull. Sure that yields pretty numbers on a dyno, but it's not keeping these motors together for more than a few squirts down the straight without blowing coolant or head gaskets. If tuners, paid a bit more attention and took timing out in the mid range, managed boost a bit better, you'll probably see less motors grenading. Not to name names, or anything like that, but I've seen a tune, from a pretty wild GT-R from a big name tuner and I was but perplexed on the amount of timing jammed into it. You would have expected a quite a bit less timing at peak torque versus near the limiter, but there was literally 3 degrees of difference. Sure you want to make as much as possible throughout the RPM range, but why? At the expense of blowing motors? Anyhow I think we've gone off topic enough once again lol.
    • Because that’s not what any of them are building these heads or blocks for. It’s to hold over over 1000hp at the wheels without breaking and none of that stuff is required to make power 
    • Dort sounds above 3k rpm are dorty 🤣 I might krinkle black the alloy 🤔
