.. after a Vortech or Procharger install? I can see it being necessary after a turbo setup due to the huge increase in torque. I'm leaning towards a Vortech, but I really hate to swap the clutch unless it's necessary. Your thoughts below please
Thanks Mike

 

Its not immediately necessary. I've only got one day of drag racing, with 5000 rpm clutch drops on my drag slicks, a track day and a couple thousand miles with the stillen s/c and no problems yet. It is something that may wear quicker than normal and require eventual changing, but not something that is immediately required.

When I had a 400hp 300zx tt, the stock clutch was good for about 30k miles.

 

the stillen also has much less torque than the procharger and vortech, like 30lbs less. so if you go stillen you could prob swing it for a while. but the others you will definitely fry a clutch eventually, unless you can be without your car i would recommend just replacing it while its getting the sc installed

 

actually the stillen has a ton more torque at low rpm and everyday driving so the wear and tear would be worse with the stillen. The stillen unit has more torque than a vortech or procharger in 80 percent of the entire powerband....

 

but less at peak, a clutch is made to hold a certain torque amount it doesnt matter where in the powerband it makes that much, once you overcome that threshhold then things start to slip.

 

Not necessarily. It depends on wieght , load, clutch adjustement and such. A simple way to look at it is a clutch can hold a bunch of torque on a dyno, but get it on the street under a hard load and things change. It's not just a clutch holds X ft lb's as load (low rpms/big torque) and wieght can have a huge impact .

Anyway I'm getting off my topic. Thanks for your help guys. I'm almost ready to take the step. So far this car has stayed NA for longer than any vehicle I've owned, but it's getting close..... Almost everything I've ever owned or built has had a turbo or supercharger. I'm just trying to cover the basics before I do it as I'm more fimilar with Ford products.

Thanks Mike

 

Yeah, a new cluch is not necessary right away. If you only intend to do street driving, and canyone carving, the stock clutch will last a very long time.

If you intend to drag race, I bet you can cream the clutch after just a few runs.

I drive my TT on the street only, and my clutch holds up decently...not great...it kinda overheats after one hard launch. I will eventually change it...maybe in the next six months or so...or when it starts slipping to the point that the car is no fun.

Establish your goals...and then decide.
