Shoot...Pete was using the OEM original stock clutch in his car all this time....so I would think you could stay with what you have for awhile.

When you start going with the spec three clutch things do grab better, yes, but things also start to break easier then too.

Yes you will need another clutch no matter what you put in...and especially if you start running slicks and some beefier axles/halfshafts of course.

All I am saying is that the stock clutch can take alot of punishment as long as the punishment is kept within means.

No stock clutch is going to stand up to the kind of power that Pete is making...probably not for even 3 passes.

From what I understand, these "Spec 3" clutches have little to no slip. Street cars need clutch slip for drivability. Also, try short-timing with 500 rwhp and no clutch slip. Good luck with that!

This will be a dillema for us all that start making above 500 rwhp.

I am really not sure what spec 2 and spec 3 actually mean...I don't think the terms are technical I think they are marketing names from some vendor. Does "Spec 2" actually mean anything?

But I know what dual-friction and race clutches are. A dual-friction clutch is good for the street and definately stronger than our stock clutches.

It's either regular clutch replacements or automatic conversion...

My notch has a lentech. GREAT street/strip automatic!!

But the 03 is going to keep it's T-56...so long as it holds up.

Do they give any actual torque ratings? How would anyone know which clutch is right for their level of power?

Will the spec 2 hold up to 600 FWTQ? How about Spec 3 and Spec 4? How much torque do they support?

Looks like the spec 3 is the ticket. My experience is, as a rule of thumb, always get much more power rating than is stated...than you need to ensure strength and longevity.

So the Spec 3 is the ticket for where I want to be. Only thing I am worried about is their description:

"Sharp but smooth engagement"

That's an oxymoron. Is it sharp or smooth engagement? It can't be both at the same time! It either slips or it doesn't.

:rolleyes:

I assume by man clutch that Raymer means stiff petal.

You hear that, Linn? It's a man clutch. You can't have one for your new 03!!

Once the HP levels get too big, isn't it time for the dual disc setup? Around $750 for the T56 Street Twin setup. You get new flywheel with it at that cost though..

I will be needing one of these things VERY soon so someone let me know which is the right one to get.
