Twin screw on a stock clutch.....

[Totsie7944]

If your spending the money for the twinscrew and the other supporting mods, why wouldn't you go ahead and build the car to handle the power your throwing at it, without always having a doubt in the back of your mind? Seems to me it would just be common sense to do it right the first time. My experience in all the builds I've done or helped on with buddies, is always build it to handle what you give it the first time, or shit blows up haha

The stock clutch is actually rather strong, mine took a hell of a beating before it went. Depends on what your driving style is, you plan on a good bit of hard launches on sticky tires and it might not live a long life. Mainly just cruising and rolling into the throttle, it will probably be ok for quite awhile....

Exactly. I am on stock clutch still with 621rwhp and it is holding fine for now. No track runs yet, which will no doubt help to escort the stocker to its grave. I think it is retarded to replace a perfectly good clutch out just because you are making "big power". Drive it till it starts to go, then do your swap. This is, of course, unless you are at the track every weekend.......

Mine lasted 1000 miles after the Whipple with 50K miles on it. I had bought a Center Force DFII for the whipple :nono: after 5k miles a new set of MT DR's it was toast. Now I'm on a Spec TD and that MOFO can take a hit.

I just had a Spec 3+ w/26 spline upgrade installed in anticipation of a twin screw...call it insurance.

Well why would you go ahead and just chuck the oem clutch if it still gripped? :shrug: Use the parts the car came with until you send them into oblivion. Its assinine to remove a driveline component like that when it still has practical use. Thats not common sense at all. :nonono:

I had the KB 2.2 on my car for 6-7000 miles and stock 50k oe still held with the 555r nittos! I should have my t76 on in a few weeks and am sure I will either snap the 10 spline or wipe out the clutch! Either way I have been surprized it held and didn't slip but I don't drive that aggressively much!

I had stock clutch at only 4,400 miles and it didn't really hold with 26x10.5 ET Streets. It slipped once and it came out. Little early but hell I don't want to waste time going to a track when you know when it does slip once good it's toast. Granted my car is a Convertible though.

I voted yes because I had a stock clutch in my car for 9k miles with a twin screw. It held strong on the street. It finally gave up on the dyno on a 21lb pull. I still haven't gone back to finish my tune for 21lbs. It did hold strong on 15 and 17lbs on nitto DRs. Also I didn't put the whipple o till I had 63k miles on that stock clutch.

My stocker made it a couple thousand miles with the Whipple before it recently started slipping. Just received my Spec 3+ in the mail :beer:
