Clutch slipping

never had this happen and since hadn't had a problem but my clutch slipped when i floored it in 3rd. i was shifting from 2nd to 3rd and when i hit 3rd it was about were all my torque is around 3k and then the rpms just started rising and the car was going any where. i'm thinking it might be time for a new clutch. any ideas if i should get one and what kind?

SPEC stage 2 or 3 - full kit. Its a good deal, and there aren't many other options anyway.

You could do the viggen PP/Disc, but if you ever plan on having more power then you just wasted all the time/money on a clutch that won't hold as well as the SPEC. I am still kicking myself for wasting $300 on a stock 9000T clutch that I overpowered within a year.

Actually the spec/Vig combo drives much nicer.. Yes i drive both of these setups all the time. I have the spec3 and Vig pp in the nira car with 340whp (~400crank) it holds solid.. Drives so much better than the full spec stg3 in my Viggen.. I hate it thats why I wont sell them But the full spec kit costs so much more.. Thats a plus right.

I have no problems driving mine with the spec stage 3 clutch. just have to understand that it is very sensitive, and not having a light touch will cause quite a shock Some people who were not used to it call it a "light switch clutch". it's not, and you can get used to it and drive it in heavy traffic - no problem.


"the average driver" who is not used to a clutch like a spec stage 3 clutch would have quite a time getting used to it, but it's really no big deal. just takes some explanation before it's driven by someone who does not know what to expect.

Yeah, the stage two is a bit grabby when it engadges, but it took me about 2 starts to get used to it. I drive in plenty of stop and go traffic and I've never had a problem with that aspect of it. The stage two disk is kevlar...in case anyone didn't know.

Yeah mine's slippin too only when it's really cold out.I have the viggen clutch which should be able to hold 330 ft. lbs., so I guess when it's cold I'm making a bit more than that.

I love my Spec stage 3, like everyone has said, it takes some getting used to and it is almost on/off, though its not difficult to drive in traffic. Plus, Ive won 3-4 30 racks betting "experienced" drivers that they cant pull out of my driveway without stalling the Saab!

Well first off what amount of torque are you making. I was gonna go with the spec 2 but Nick told me based on the torque I had that the viggen pp/clutch combo was perfectly fine. He has the torque load for all sorts of combinations on his website. Go check it out and pick from there.

Pretty much the same thing as me except the intercooler. Run with the Viggen PP and Viggen clutch disc as thats what Nick said would suit me best.

The way I see it, if your planning on going bigger, why not do a clutch disck/pp that will remain usable for future plans? If your happy where your at (who is?) then go with the Vig PP/clutch.

Because until you go to a ball bearing setup 300+tq/hp the viggen combination is perfectly fine. If its gonna be some time before you go down the BB route then go viggen.

Adam (a12) is making the same power numbers I am, for all intents and purposes, and is having trouble with the Vig PP/Clutch - just some food for thought. Maybe he doesnt need it right now, but for the time and or money of the install (depending on if he does it himself) I just see it as a better investment to upgrade for future plans while you have the oppertunity, vs. when your in a situation that you HAVE to.
