CAT600

Got into this thread a bit late, but ive run the triple carbon in the AU and in the end while not a bad street clutch that will take a lot of power found it too angry on drivelines, especially when hot it will get very grabby and start killing driveline bits... I lost two T-56's to this clutch (both the older synchro design) since I went 9" diff and the PPG dogbox no issue but its not that nice to race with. I went to a Spec stage 5 (sintered iron disc) a couple of years ago and never looked back, rated to 1000lbft it will be good in a turbo 6 to about 550rwkw id say and is great to drive daily and perfect at the track as you can slip it a bit. I have done 12,000kms on it so far and about 20-30 6000rpm sidestep launches on slicks with the twinscrew at about 550rwkw.,,, the triple carbon was retired to the Twin Turbo (until recently I went back to the ZF) and was great in there because it didnt see the strip as a manual... good for the dyno will take a lot of torque!

Actually the new K-Mac ones look like an almost exact copy of mine. I am almost out of the last batch but will probably get another 10 sets made next month if the interest leves are still there. Ive made 60 sets now with one running change about halfway through and never had a set come back after they were installed. I dont have vibration whine/NVH in mine but there is a small amount of backlash noise there compared to stock. My Twin Turbo runs the earlier style I made and has done 20,000kms with the stock halfshafts still in there to this day, done 13,000kms as a ZF auto car and 7,000 as a TR6060 manual car, all with upwards of 500rwkw daily driven (is 600rwkw at the moment on 98 with the 5.0L) George I have one new set and that set we spoke about last month available, I will call you when I get home to run through which way we should go with that... need to take another look at that early set and check the OD and measure them up. Daniel

Cheers and great time from your ute, was good to meet you as well, Simon has mentioned your car a few times but I had the two blue utes mixed up in my head.... Just need a Ford vs Expensive Daewoo track day organised Between Simon and Eddy and we'll be set! Daniel

It has Dean, but I was going for a 9..... it was not to be with the changes I made to the rear end (different springs), My thoughts were that going from a 3.25:1 ratio at Heathcote to a 4.11 here would need more tyre, but with the rear end bouncing the wider rubber I ran (10.5", up from a 9" tyre) was ineffective. Next time out I'll run the old springs (lower and harder) with both tyres and see what happens For those that dont know the car: 5.0L Modular 4 Valve 2.8H LC Kenne Bell E85 fuel T56 with PPG heavy duty gearset Final Drive 9" 4.11 ratio 10.5 x 28.0" tyre (still spins them hahah) 4,240 lb with driver as raced VIDEO'S: https://www.facebook.com/photo.php?v=437346066278095 https://www.facebook.com/photo.php?v=437270952952273 Car actually ran the exact same time twice... 10.111 @ 140.62!

Daniel

Cheers Simon. For those that dont know the car, its an AU TS50, Kenne Bell supercharged 5.0L Modular engine, T-56 manual trans with PPG dogbox and a 35 spline 9" rear end. Car is daily driven on BP98 but ran E85 for the meet making over 700 wheel horsepower. 60'....1.64 660'... 6.59 @ 110.78 1/4..... 10.11 @ 140.23 Car was awesome pulling 10.30-10.50 In Friday testing then grabbed this time with the first pass on Saturday morning in better track conditions... Came around to run my 9 and it slipped the clutch all through first and proceeded to weld the metal clutch solid... Weekend over. There is a stack of potential left in the car as it runs a tall 28 x 9" tyre and 3.25 rear ratio meaning it was crossing the line in 3rd gear at 7000rpm... Going to build a 3.9 rear centre and use 4th gear which will see the 60' times drop into the 1.5's and the 9 second pass will be there for the taking. http://i818.photobucket.com/albums/zz106/FTE056/P1020930.jpg http://i818.photobucket.com/albums/zz106/FTE056/P1020952.jpg http://i818.photobucket.com/albums/zz106/FTE056/P1020913.jpg http://i304.photobucket.com/albums/nn183/janellewhittle/IMG_1085.jpg
