Clutch

[itsallyellow]

What clutch is the best one to go for? Want to replace the standard road version. The car will only be used on track and i need somthing that will last etc.

Any ideas?

Thanks

Well i've just dynoed a car with a lightweight flywheel which shows a small but worthwhile hp gain at the wheels on an accelration run on the dyno, and there's a lightweight sintered paddle slutch coming soon aswell .. so might be right up your street? have a word with your engine builder later this week after I've seen him

Very interesting Julian.
Roughly how much is a new lightweight flywheel though?

Guys,
Anyone know if any kits offer stronger clutches?
Are these Clever Trevor kits worth looking at or are they no better
than standard?

Orignal clutched re an effort to get though via stock IIRC?

I've heard the test rig (whatever it was) abused the CT clutch and it held up fine. So I have one in mine now, fitted by Leven.

And it hasn't broken.

ahhhh feck I've said it now.

What dyno was that on? Is it a "Mass" dyno where it calculates hp from the rate of change of sped of the dyno drum?

A lightened flywheel won't give any more horsepower as such. It will improve acceleration times and change of speed of the engine which can imporve driveability (on a car that's driven hard). As far as physical power goes you're not reducing the friction or improving airflow with a macheancial part such as a flywheel so physical power can't really be affected.

Yes but the power at the wheels will increse as there will be less drive train loss..

[ridds]

Same losses as friction has not been reduced. It's like saying lighter wheels give you more power. A different size will affect the gearing and thus effective torque applied but the engine output is still the same.
