Ive had a Jim berry clutch in my car for ages and he said to remachine the standard flywheel as the weight would be better for the drags. Mine has held just under 400rwkw for months with lots or hard driving on street and at the track with slicks.

What ever he tells you go with that.

He's been doing this for more years than you've been alive. You don't stay in business that long by being a d1ckhead. Have a chat to Jim for 5 mins (good luck, he likes a chat) and you'll see what we all mean.

I have no need to chat to jim about clutches, i have my own place locally called DIRECT CLUTCH

DIRCET CLUTCH > JIM BERRY

thanks anyways :D

and hes been doing clutches for 25 years WOW :thanks:

Richard, if you're still reading, any idea what kind of power levels the cars that you know of that blew a flywheel?

one as low as 230hp exploded going down the main straight at oran park. benm i'm guessing was around 300rwkw exploded on launch at WSID. there was another guy on here with a GTR and a JB clutch and stock flywheel that exploded (Paul will remember I think he worked on the car, or knew the guy at least) I can't remember the nickname of the guy or the exact circumstance. a friend in a silvia had one go with around 200rwkw.

can probably dig out more examples but that should be enough.

    • Got the motor out and torn down. I'll be dropping off the block Monday. Luckily the scoring on Cyl6 is much less pronounced then the pictures made it out to seem. It can barely be felt. If you pass your finger over it 10x you'll barely notice it. Hopefully by some chance it will only require a honing. I'm not in the mood to buy one size larger pistons or another block. Oddly enough my 6th cylinder with the scoring has extremely clean intake valves compared to my other 5 cylinders. I'm worried the scoring was caused by too much fuel or Water/Methanol washing the cylinder. I'll review some old logs to confirm.  This was also the first time I pull an engine with the transmission still attached. It went much better then expected. I was worried my CD009 wouldn't make it easy due to its sheer size but it was much easier this way. 
    • From the pictures I have when doing the job the flywheel is the same diameter, I don't think they're playing weird tricks like putting weights at the outer diameter to increase flywheel inertia or anything like that. The OEM flywheel is definitely heavier, but it's not a huge difference. Quoted weight savings of the clutch is 2 kg so I can't imagine the flywheel being lighter than ~7 kg. Kind of regret not weighing it before the clutch went into the car but as far as driveability goes I have no complaints.
    • HKS trigger kit should be very easy to integrate with a Link. It's a 36-2 crank trigger. Hard part is finding the motivation to take off the timing belt and everything on the front of the engine to install it. You also need to cut out a hole in the oil pump housing so the sensor can read the trigger wheel. Changing out the cam sensor for a 24 tooth setup is probably good enough but as others have mentioned depending on what underlying assumptions are changed it becomes more of a problem. Reading the crank state off of the cam is an abstraction that works in the general case, but if you have an edge case it makes less and less sense. There is a GTX2860 gen 2 that can take a compact 5 bolt housing so it's direct bolt on but I'm not 100% sure of what's involved. Peak compressor efficiency drops off a bit on these turbos vs -5s, 77% vs 73% but you get way, way wider region of operation. The -5s have a really strange surge line in their compressor map that is all over the place. If you think the hot side on the -5s aren't open enough you can try the Tomei T550B turbos which a local tuner seems to be happy with:
