Best Clutch??

[brownz]

I went with the LS7 clutch and LS2 flywheel heard that its the best for cost,drivability and holding the power.

Anyone have the part numbers..

[Jesse@SDPC]

You won't get them cheaper locally, unless you basically get them at dealers cost. Give me a call at 1-800-456-0211 and I will help you out.

It now comes with new flywheel bolts and new pressure plate bolts. We have great prices on the slave cylinder/throwout bearing as well, $109.99 for you guys running the f-body setup.

Thanks for the call! If you have any other questions at all just let us know, we're glad to help you out

I too am on board with the LS7/LS2 setup. No miles yet, but soon....

Another vote for the LS7 clutch. I have it in my GTO and its very nice.

The dyno shop (turboconnections) says a aluminum flywheel is a instant 20 rwhp difference he has done this several times.

There's no way to say this without sounding like I'm trying to insult anyone, but precisely what Laws of Physics does a lighter flywheel allow you to ignore that you make more power?? A reduction in rotational mass will not & cannot "make" more power. It'll just allow the engine to rev quicker, which allows the car to accelerate faster. That will show on a dyno, but only under acceleration, not at a steady state like when peak HP is measured. I'm not knocking Turboconnections, but that's one dyno operator's charts that I would probably not trust...

Power is the rate of doing work, i.e. acceleration. Torque is steady state. Power is calculated from torque @ rpm. If you reduce rotating mass, it will generally accelerate faster hence goes to a higher rpm quicker giving more power over the same time period if accelerating at maximum rate. Assume this is what is meant when they say you gain power with a lighter flywheel?

Yes. So you can gain HP from a lighter rotating assembly, but torque will be unchanged.

You are correct in stating the engine will not make more power with a lighter flywheel. The RWHP gains are due to the less power lost turning the lighter mass.

I am using the LS7 clutch with an LS2 flywheel. You can get complete kits for around $550 for everything (clutch disc, pressure plate & flywheel).

My clutch is very smooth and has a reasonably light pedal. It has worked very well with my 600 hp so far, so you should have no issues at your power level. There is also the peace of mind of it being an OEM part that is readily available and engineered to be reliable and durable behind a 500 hp motor.

Why the LS2 flywheel instead of an LS7 one?
