2006 G56 clutch slipped...

[ENafziger]

I've got a TST CR-49 with the Edge EZ stack, and so far had no clutch slippage at any setting on both chips... that is until Sunday. On the way to church, roads were wet, and I don't know what came over me. I tried a 3rd gear 2500 rpm take-off with the chips set on 7/7 and 2, and pretty soon I smelt the unmistakeable stench of burnt clutch material. I know that was a little irresponsible with a stock clutch, but I figured the tires would break loose on wet pavement before the clutch slipped. Have I damaged the clutch by doing this? Once the clutch has slipped and glazed, is it more prone to slipping again?

I think you allready know the answere to the question you asked Thats why Im an auto guy

Funny You Asked That I Did The Same To Mine But I Was Being Pretty Hard On It On Dry Pavement. Well Lucky For Me I Work At A Dealer So I Had Mine Replaced. But Not Until My Techs Told Me To Really Fry It. So For A Few Days I Had Been Slipping It Purposely. Well When We Finally Got It Apart It Was Not Really That Bad Actually The Only Problem Was That It Had Turned Blue From The Heat. It Would Have Lasted For Alot Longer If I Wanted It To.



But In Your Case I Would Be Looking For The New Sbc Con Fe. I Will Be Getting One As Soon As This Stocker Lets Go Again.

Definitely give SBC a call.



You may not need a FE, though, unless you plan on that kind of abuse. With a TST twins program stacked with a MP-8 I have not yet found the holding power limit of my new OFE. It drives almost like stock, but holds everything I've thrown at it so far... But I don't do 3rd gear launches, either. You'd be better off with a DD if you're going to do that.

I just recently snagged my new CTD and was wondering what SB has for the G56? I plan in the future to bomb but would like to have a stout clutch first!

JCleary, The SB DD 3600 12CB would this be a good clutch to go with to do sled pulling at the local fair grounds, 3-4 pulls maybe a few more a year? and would it be street friendly? I pland to do a clutch for my first mod and not really looking to do any drag raceing, but playin around on the back raods

BSwope,



Yes. Do it. Don't get the FE if you have any "planned slippage" Boosteed launches, etc.

Absolutely go with a DD if you plan on pulling. I've heard that the metallic clutches are a bit smoother, but I haven't driven either so I can't speak from experience. Maybe someone else will chime in...



If you're just goofing around on the street, I think an OFE or FE will be better. I switched from a street dd to an OFE and am not looking back... I love my new clutch.



But I'm not drag racing or sled-pulling either.

Now That Im Reading This I Plan On Putting Down About 550hp What Clutch Would Best Benefit Me. I Play On The Street Alot. Drag Race Occasionally.

Peter told me that with the new 3400-3600# pressure plate the OFE will hold 550hp. I hope so, as it's what I dynoed at last. So far so good.



If you want a fast shifting clutch that's easy to drive, get an OFE or FE. If you know you're going to beat on it, get an FE. It will take more abuse than the OFE, but may be a bit grabby while backing a trailer.



If you're drag racing and plan to do 3000rpm 3rd gear launches, you'd be better off with a dual disc. The dd clutches do shift slower, are loud, and sometimes need to be finessed into gear at stop. The organic dd has less rotating mass than the feramic or ceramic clutches, so it does shift a bit quicker. The trade-off is that you won't be able to sled-pull with it. Building boost by slipping the clutch is not an option either with the organic. I was told you need a quick spooling turbo and enough fuel to get the clutch hooked up quickly, as in a couple of seconds. Otherwise it overheats.



The feramic and ceramic dd's can take that kind of abuse.



I'd say go with a single disc unless you are absolutely sure you're really going to punish your truck. I went with a dd first, and now have an OFE. I'm happy with my decision.



Additonally, I have to say Peter is an awesome guy to deal with. He stands behind his products 100% and will get you into the right clutch for your application.

EXACTLY!





Only thing I would add is the fact that the FE will not "hook up" after being slipped. You have to back off the power, let it engage, then get back on, compared to the OFE will engage, but the FE is good to 550, and the OFE to 450.

Thanks for the info fellas this helps out alot!

 

[ENafziger]

Good info. In short, I gather that a DD should be used for sled pulling, while a SD offers quicker shifting and may be better for street use.



Would a good SD, such as the Con FE be well suited for heavy towing on road? ... not sled pulling abuse, but pulling a 20k load on the street.



Will the SD Con FE tolerate an occasional 3rd gear launch?



For daily driving, is a DD a nuisance?



JCleary, what made you give up the DD to go with an OFE?



Still learning, Eric

 

[MCummings]

Will the SD Con FE tolerate an occasional 3rd gear launch?

On a light truck, yes. On my 3500 2wd, no.



If yours is a 4wd, a 3500, or both, then the FE will not, but it will on 2500 and in 2wd, but in 4wd.
