Anyone know what clutch is holding with the tst. ?
Awesome power! looks like clutch first then turbo.
Gotta love it when you have to mutch power !!

Thanks.

 

I will be upgrading to a South Bend Dual Disk "Street" clutch when I finally decide which box to get.

 

I have an FE going in on mine.

I recall reading the OFE is not enough. I might even be shy on the holding power if I add injectors after the CR box.

The dual disk may be the best way. Harder on the synchros. I will let you know what I learn over the next few months with the FE.

Scotty,
Why would dual disks be harder on the synchros? I am looking to upgrade so I will be interested in your report on the FE. Particularly on how streetable it is.

The dual disk clutch will add more rotating mass on the input shaft. The additional mass and vibration will eventually lead to earlier synchro failure than you would have seen with a single disc clutch. The South Bend dual disc is the lightest of the duals available, however, Peter is still pretty confident that synchro failure will occur within a couple years of installation.

The Con FE for the third gen truck is going to be pretty much the same as the Con FE for 2nd gens, only with a higher plate load. The higher plate load will give you a harder pedal pressure, and you may have a little rougher engagement of the disc. As always, this will not be a clutch that you can ride, as the ferramic materials cannot hold up to riding of the clutch.

Push Rod,
Thanks for the info. That clears up the dual disk question for me. As far as the FE goes, I don't tend to "ride" a clutch but I would like to be able to slip it while I am backing up the boat (as an example). Can you do that with an FE? Thanks,

Nope, the ferramic material in an FE clutch will not allow for slippage at all. It'll simply grab. For low speed maneuvers, I recommend using 4 lo.

hummmmmmm........I may have to re-think the "Grand" plan. Thanks for the info.

I can ride mine for backing up my boat but it requires a precise throttle/clutch application. Piers sells a two low kit that I was thinking of purchasing to make it easier. I will be getting to that one soon I think.

 

Be very very careful while slipping a full ferramic lined clutch. Ferramics can be damaged by slipping, and can flake, destroying the seat. If you find yourself jerking while backing up, you are doing some damage to the clutch facing.

Its interesting about the 2-lo kit. Is it for the 03s and up? I know there was one for the 01 and down, as they used a central axle disconnect, but I was unaware of anything for 02 and up with the full-time hubs.

Rod

 

Boss, I ran the FE in my 01 and never had any issues backing up in 2 high. It was not as jerky as some described and to be honest...bumps under the tires and rough terrain where worse then anything the clutch did.

Stay with your plan.

Scotty

 

The SBC Con FE will jerk more than the SBC Dual Disk. I ran the FE for 25K miles, and switched recently. The dual is smoother on engagement, and when backing up a heavy load(14K+), the Dual can be slipped much easier.

As for what wore with the FE, the flywheel took the most beating when jerking too much. Make sure you get a good cut on the flywheel. My original cut was not through my normal machine shop, so when we reinstalled the FE into a nother tuck, I had my same flywheel cut by my normal machine shop, and the clutch is much smoother, but still not as smooth as the dual, on engagement.

This same FE saw every conceivable power combination, and with the TST and EZ stacked with DD2's, it help good, but I knew it wasn't going to last , so the dual went in.

The dual is rock solid, and when it grabs under hard launches, it doesn't think about slipping.

 

I believe I read in another forum, Mark at TST is running the new Luk HD clutch in his 03 6spd. I do not know what mods he is running on the truck.
