Clutch decisions....

[re-rx7]

So my clutch started slipping last night. I have a stg 3 XTD 6 puck with about 8k miles on it. Alot of daily driving and stop and go on a puck = a short life span. Anyway after thinking, im wondering if i realy need a 6 puck clutch for what im making horsepower wise..
This time around im thinking of going with a stg 2 XTD for longevity. I dynoed 240 whp and 245lb ft on a mustang dyno. Probally a lil more now since im running a few more lbs of boost on my Fp28. Would the Stg 2 XTD be enough? Any other suggestions welcome.

Thank you

The XTD Stage 2 clutch should be good to a torque capacity of 276 ft/lbs and hold up to 310HP. The Stage 1 clutch specs out as good to a torque capacity of 248 ft/lbs and hold up to 279HP.

I preach about this clutch setup near religiously. The Southbend clutch assembly sold by TMZ Performance.

TMZ Performance - Southbend Series Clutch

It's Kevlar, so it's forgiving. Feels very stock. Handles just about anything you can throw at it. Give the information a read on that page and do a Google search if needed. There is more positive information on this clutch setup than you can enjoy reading.

Example -

The South Bend Clutch TZ-Series Sprung Full-Face Kevlar Disk was used in my race car for 3 years of extreme abuse, and withstood very high horsepower and torque levels of 500-630WHP and 460-590TQ (numbers are from dyno-tests on a 2WD WinDyn Super Flow Chassis Dynamometer). It withstood a couple hundred track passes, over a hundred dyno pulls in this power level range, and over 30,000 street miles with regular launching, stop-and-go traffic, and fast shifting up to 8600-9000rpm. Three years later when it was taken out for a clutch upgrade due to my increased power levels, it still had more than half of its friction surface left with no uneven wear to the clutch pressure plate or the clutch disk!

Also, when you do your clutch change, it's a good idea to check your clutch fork and pivot ball for wear and replace as needed.

Lots of gd reading in that link! . Im starting to think the XTD may have died due to oil contamination. Lot of oil residue on the bottom of the tranny where the viewing port is.

Personally I prefer a.c.t over any clutch(for daily use) try a 2100 clutch, I bet you'll like it.

ACT is very well known and has a lot of backing. There are great stories, and there are disastrous ones. I've ran an ACT 2100 and I enjoyed it. Was absolutely no problem with it aside from the fact that it didn't hold the power I wanted. The thing I don't enjoy about ACT, however, is that their answer to everything is increased clamp force. Those clutches get so heavy they lift you out of the seat to press if you're not a large person.

Other competitors such as Fidanza who focuses on 2300lbs of clamp force, if I recall correctly, and uses various types of material for inreased grip with captured sprung disks - That's something. That's thoughtful and works great. Then there's the TMZ Southbend that holds up to a tested and proven 650 TQ and feels stock?! You just can't get better than that. I've personally owned as well as driven at least one other vehicle with the TMZ Southbend setup and it's just absolute pleasure. Soft, quick, and when you want it to - it has bite.

So, ACT has proven it's name time and time again, but at what payoff? 3200lbs of clamp force with an organic disk that may or may not collapse?

Tmz southbend hmmm... Ive never heard of that clutch I'll definetly look into it.

A lot of dsmers here use the south bend clutch run a act personally, but many have good reviews on the south bend.

SOuthbend may be my choice. The XTd was hard to beat for the price at the time.

I use South Bend as well and definitely enjoy the lightness in pedal pressure.

Very good read thank you.
