Default Is anyone considering a lighter racing clutch

I know on the 300zx you could get a clutch that was lighter and freed up i believe 10-15hp. A friend of mine currently has a silver 92 300zx and he did this mod and i could really feel the difference. Throttle response was really increased. Since we already have the carbon fiber drive shaft i think this would be another option to consider. Not sure if there any out there or if anyone is working on one. Let me know if you guys have any info.

Thanks Guys

It was a fly wheel not the clutch. I dont really like the dual mass flywheel so i would seriously look into a new one.

You'll notice the effects of a flywheel much more on a turbo'd car than a NA car.

Default Im sure that a turbo car would see bigger gains

But i did notice a big difference on a stock 300zx non turbo with just exhaust and intake. Car felt alot stronger and got up to 60 alot faster. I would say his car had 222hp stock with intake and exhaust im thinking maybe 240hp.

Your right it is a lighter flywheel, but dosent that come with the whole set up ( clutch and Flywheel together )

Flywheels don't make that much of a difference, they simply reduce the amount of drivetrain loss (maybe 1%). No, clutches and flywheels don't come together. When you buy a "clutch kit", you get the pressure plate, clutch disc, and a replacement throw-out bearing. It is also suggested that the current flywheel be resurfaced (unless you plan on replacing the flywheel altogether).

How much HP is freed up with each pound of weight you save on the flywheel. If it ways 22lbs stock ( guess ) and you take it down to say 14lbs what kind of increase would that yeild. Just curious.

Actually you can get flywheel clutch combos that both are lighter. A good example (and the lightest in the world) is the ATS carbon clutch. The disc is pure carbon fiber and lighter than a feather. Flywheel is cored out at the outer edges to keep all the weight on the inner portion and is available in single, twin or tripple plate configurations. Makes a HUGE difference.

Wow! You guys are making everything for the Z.

Is the flywheel going to be chrome moly or aluminum? I see most companies use aluminum and have always heard horror stories of them breaking and doing lots of damage... is there any truth behind it?
And right now, I find the clutch on the Z to be too soft. With your clutch, is it the same feel or is it going to be stiffer?

There is some stuff that was posted that we are not going to make. You can take aero kits off the list. We are mainly doing our own suspension stuff, but you just never know what else we will have.

Yes, alluminum flywheels can be dangerous if not produced properly. Most of the time the failures happen due to the bolts or fasteners holding the steel plate to the alluminum flywheel. There always has to be a plate since alluminum can not handle the heat. The fasteners will either fail from torque, or from the constant expansion and contraction of the alluminum (steel and alluminum have different expansion rates). Because of this alluminum is never used by any Japanese company for flywheels.

So when you say there is a clever idea, do you mean you have already replaced your clutch and flywheel???????????
