Going to finally pull the trigger on this clutch after talking to peter I think anyone run this clutch and how do you like it over previous clutches right know I run a 13.125 fe, and would like the option to boosted lauch once and a while as well as keep rpms up when shifting.

any pro's or cons if any would be great!

I like mine, especially holding the power I have and still have decent street manners. If I had to do it over again, I'd probably go with a 3850, however I don't think they are quite as drivable on a daily basis and I think petal pressure goes up more significantly. I think the 3850 doesn't have quite the street manners the 3600 does, but I'm just afraid I may be on the brink of going over on HP.......Again. Boosted launch is tricky.....you can only use so much boost to get it hold. It supposedly is pretty tough on the clutch. I'm a little nervous doing it.....dragway only, but still makes me a little nervous, that is why I don't do it often.

 

I have the 3600 DD Spring Hub in my 05. I pull a 26' gooseneck on a regular basis. It has good manners taking off in 1st or 2nd once you get used to it, but is a little grabby backing up. Just takes some getting used to. Gonna do the front hub conversion soon so I can use 2wd low range.

 

I have the 3850 sprung hub and I love it. the peddal pressure can be a little much in heavy city traffic, but I don't mind it. I tow with it and daily drive my truck.

 

4200 here daily driven.

 

Sorry to hear that.

I've got the unsprung 3600 and love it. If I were only driving on the street and not going to try to pull a sled at all, I would definately go with the 3250. A buddy of mine has it in his and actually hooks to the sled but his is starting to wear. His drives AWESOME!!! A lot better than mine, or at least it feels that way to me. It drives almost as good as the 2 FE clutches I had. Very stout clutch with light pedal and smoother engagement.

 

tiger.... I was under the assumption these things could take gobs of boost under a launch? Not the case, I do not want to have more pedal pressure and still slip the clutch under a launch or a WOT shift like I have right know with a fe mine will slip if I give it to much and once it slips it will not grab you have to shut down for a couple seconds which by then you either lose the race or get laughed at which has happened

I simply want a clutch to close the auto to manual gap, and being I want the 5sp this is my way of thinking I can even the field a little, keep in mind this truck is not built for drag racing only proabaly do it 3-4 times a year. No sled pulling now or ever not into that...fun to watch though!

2whistlers are you saying your fe was a better clutch?

Thanks for the posts guys!

 

No way to really close the auto to manual gap. When I've done boosted launch, it slips for a bit before it grabs. Still haven't broken below 2.0 sixty foot time. Probably trying too much boost. I'm similar to you in that I'm not really ever going to drag race or sled pull much, just playing around with it. In the end it is still a street truck that I pull a 15k gooseneck with.

One other thing. You could always go with the 6cb. It won't be as street friendly, but the big buttons should hold better on a boosted launch. I know they're supposed to be better for sled pulling.

 

Yep, I figured that clutch wouldn't be bad on a daily basis as mine is no problem at all. Just from SBC's website they say petal pressure goes up a good bit with the 3850....that was the former unsprung version though. Man, I hope I don't have to pull that big sob 5600 out again anytime soon.

 

I realize I willnever match a similar auto truck however to "close the gap" would be nice, what was the differnce in 60' from the fe to the dd?

 

Here is an adder I put to the other post:

Petal pressure should remain at a comfortable level.

My 60' times have come down a bit from the old OFE, but I wasn't trying boosted launches at all on the single disk and I don't think I've got it figured out yet on the DD. I hope to break 2.0 and I'll be pretty happy. I think I was running 2.20's on the OFE and now I'm at 2.01. If I can get the clutch to grab sooner I think that can be improved. I have probably 150 more hp than I did on the single disk so that is where a lot of the improvement is coming from.

 

I dd a 4200 unsprung too. Not near as bad as everyone makes it out to be. Pedal is a little stiffer, but my gf and sisters can handle it just fine?

Does it affect your shifting at all? Clunkier or anything? Heck, if I have to do another, I might just jump up there. Not that there is anything wrong with my 3600 right now, just want the clutch to grab for a boosted launch.

 

what is the most boost you have thrown at it? Peter kind of relaid to me that it would take the slipping and grab... but I do not want to shell out 3000 can funds to get a marginally better clutch.

 

Mines a 3600 unsprung but I've made over 40 lbs on launches. Third gear hooks up so quick it just burns the tires off. 4th gear and the clutch slips for a second or two before grabbing and by the time the tires hook up good I'm going 60 The clutch does *not* like 4th gear launches though.
