What does the term designate?

Thanks!

CMH

turbo or supercharged cars.

that I would like to put it in my car.

It's like: what's an autofocus lens? How is it different from a normal lens?

Fundamental like that. So what is it, and how is it different from whatever clutch we have?

basically it's a clutch sandwich of sorts.

The stock setup has a flywheel, clutch plate, pressure plate.

The multiple plate setups have flywheel, clutch plate, pressure plate, clutch plate, pressure plate...etc.

I think it's mainly used since you have more friction area and greater adjustability.

I don't get it. Except for increasing clutch force (something which isn't modelled in GT3), there is no downside to better clutch grab. So why not throw a triple plate on?

Except the terminology would be:

flywheel, friction plate, driven plate (because its driven by the flywheel) friction plate, driven plate, friction plate, pressure plate.

Triple plate clutches are used for phenominal holding power in a small package. The factory Audi single plate clutch is about 10" in diameter, clutch disk and pressure plate are what? 10-15 lbs, and can hold what ~300 lb-ft (I know Stage three guys report slippage). A Sachs F1 clutch can hold 800 lb/ft and is 4" in diameter, and weighs 30 ounces. Its Carbon Fiber & Titanium. Tested to 20,000 rpm burst strength. The smaller diameter allows for less rotational inertia, which means those V10s can hit 18,400 rpm in qualifying trim just that much faster...

is that a lot of turbo motors are four cylinders, and don't have the low-end torque needed to take advantage of the improved grip, and could possibly cause lugging.

Of course, if you had a twin-turbo V6 or V8, you could probably use one.
