Mitchells pulling clutch?

[DRR-24V]

Hang In There Peter !!

Most of us guys buying your clutches are not pulling sleds. Don't worry about it. You have an excellent product and are on my WISH LIST.

 

[Don M]

I have a SouthBend clutch and so far have had very good results with it. Just under one year and lots of raggin on it have not hurt the thing yet.

I have slipped it at high HP levels, but it is the organic material clutch and the smaller 12 inch for the 5 speed.

As the truck sits now it is at a measly 450HP or so and the clutch will not slip even with a 8800lb truck.

Not bad for a clutch that engages and drives better than a stock one does. Once I get my injection pump out of the shop next week and perform some more tweaks the clutch is going to need an upgrade to the bigger and better 13" FE clutch to hold it all



The guys that know how I drive this truck can tell you I dont baby the Ram. 4000plus rpms daily and dumping the thing hard and it still holds up.

[BI do know you are the only one who ever MELTED the brass pucks, and brass alloys melt at 1400-1800 degrees. "Trust me" How much slipping does it take to get a clutch that hot, and who cannot tell that the clutch is being abused when it is slipped that much?



[/B]

I beg to differ Joe, there is a few that melted down that you replaced that did not have sled pulling on them. That statement is FALSE.



Also keep in mind that YOU TOLD US TO SLIP THEM.

That would "heat" them up and hold even better.



Sorry about your name, not on purpose!!!



Has anyone seen you race it?

Has anyone seen you smoke the tires?



Have you done anything besides get on the dyno?



When someone brings it up, I go off Joe, I'm sorry, I hope the pain will heal in time, and I will be able to read it without smashing things, LOL.

I felt you misrepresented your clutch, you feel you didn't, here we are.







Peter DOES make good products and has happy customers.

That is not in question.





But he has to realize that when people need max holding power, he does not have the product for them.

And he does not need to slam another venders product that is working QUITE WELL trying to sell his, under the guise of:



"His advice seems to me to be well-meant, and to inform folks that nothing lasts forever, and everything has inherent compromises that need to be considered. "



I have seen him do it before, and I finally spoke up about it.



He does not need to worry about Mitchell's misleading people.



Even to THINK it, is way out of line.

 

[Joseph Donnelly]

Nope, Gene, you're the only one who melted the brass. A few others did have problems, not that. Each person got a free replacement, no-fault basis, regardless of why. Since I gave you a free replacement Sachs, why don't you reciprocate and give me a free Mitchell clutch for Sickly. I promise not to melt it, and Sickly does have the power to use it, 609 hp, remember.



Then, having done the right thing, you will not have to smash things any more.

 

[Sled Puller]

Joe,

If I knew you would USE IT for what it was meant for, I would do that.

But your transmission is due to fail from your poor lubricant choice anytime, and you would blame it on the clutch!!!



Now, get back on that porch afore I come out there and put pur Sickly out of his misery!!!!

 

[South Bend Clutch]

I know I said I would not post on this thread again but Gene you did it again!!!!!

But he has to realize that when people need max holding power, he does not have the product for them.

And he does not need to slam another venders product that is working QUITE WELL trying to sell his, under the guise of:

Just earlier in this thread I said in a post... .

By the way Gene, for what you are trying to accomplish... . the clutch you have is the BEST choice on the market as of now.

Do you only here or read what you want or maybe you just missed this post.

[Sled Puller]

Why do you keep repeating yourself and then go post the same thing?



Is there a doctor in the house?!?!?!



Apology accepted Peter!



I think all of our points have been made.

Thanks for seeing things my way Peter, it means a lot.



Gene

 

[Turbo Trucker]

Gee I didn't mean to start all this.



I have come to the conclusion that I need a bigger truck for the amount of weight I pull and the distances I want to go. I'm pulling a GCW way beyond what the Dodge is rated for.



For now I'm going to go with the 13" upgrade. I'm going to get my business up and running, I just got my MC number so pretty soon I will be able to hopefully get some steady work from brokers. After I get running I would like to get a full size semi, and eventually get a 7/8 car trailer.

[Sled Puller]

Ha!

Wes, not your fault, it has been brewing for some time!!



I am sure the 13"SBC will get you by for quite sometime, perhaps as long as you own your truck!!



But IF, it gives out on you,you know where to go next time!



Now, lets talk about your transmission lubricant!!

 

[Don M]

Gene,



How bad does the clutch you have in your truck rattle? Could you provide a WAV file or sound clip to listen to? I would think that the rattling would be objectionable in a street driven truck.



Don~

 

[JTroiano]

Way to go Peter, I would buy your product just because of your customer service. I may need a clutch soon I work for a Luxury car company and customer serv. makes a big difference to people.



Sled Puller, I don't know what to say.



WWaddell, thats scary:--) You need a bigger truck! I thought I saw a truck like that in Beaverton OR last week?

[Sled Puller]

JTroiano,

Prolly best!





Don, it only rattles when it is disengaged, with windows up, you can't hear really hear it, at least I can't.

Of course with my timing CRANKED, the engines clatters a little louder.



A very small price to pay for performance, for what we are doing with them.



Trust me, it sucks having power you can't get to the ground, that is why people who get them speak out.

It is awesome being able to Hammer that baby and know the clutch won't slip.

 

[Don M]

Gene,



The clattering is the piston being hammered too early. Ive tried high timing and you actually loose power in the range you use to drive the truck on the street.

Why not just run the high timing on the track and put it back to daily drive around? That is what I do. I time my engine depending on the condition I drive the truck.

Dyno stuff or drag racing I crank it up a bit. Driving around I turn it back a bit.



when are you gonna put that 180HP california pump on the dyno?





Don~

 

[Joseph Donnelly]

Lessee, puller clutch, HD input, and fine transmission lube--I'm just sitting on that porch trying to decide between Torco RTF, Castrol Syntorq, or maybe LE 606 (lighter than 607)? You don't know of any other good lubes, do you



Yep, he's spun up real good, like an HX40 at about 57 lb boost. I know what happens next

 

[Sled Puller]

Don,

Are you saying 28 is too much for street use?



I will dyno all in good time, and I may/may not disclose results!LOL



Joe, try the 606. 5. mix with one part Torco, throw in dab of diesel, and you should have it about right for what you do with it.

 

[Don M]

Gene,



Once you get some wrench time under your belt you can set your own timing. This is a good way to see how different timing amounts can change performance for a given rpm range.

28 degrees is bit excessive for a street driven truck, IMO.



Something around 16 or so for the street and it is a little easier on your rod bearings. So, gather up the tools needed and contact me for some pointers if you like.



Don~

 

[Sled Puller]

I have plenty of wrench time Don, don't you worry about that.

One of these days I will get those tools gathered up, but it is not top priority at the moment, as a few of my friends have them.

The tool box has been ever growing since I have benrunning theses things the last several years.



And thanks for the offer of help, but I go to pros for that kind of help, hobbyists for gauges.





Besides, that 5-30 will handle that extree pressure!

 

[Don M]

Did the pros tell ya to set the injection pump timing at 28 degrees for street driving? I guess the little bity 180HP pump needs a lot of help to get those twins spooling up.

5/30 will squeeze out of those rod and main bearings faster than most others weights. I guess you can rely on the everchanging additive package to for barrier lubrication though.



Maybe the Delo you are running now and changing on a frequent basis would be the best way to help those bearings live. Goodness knows they are being hammered to death with 28 degrees of timing.

SCATTERSHIELD BELLHOUSING

After reading all of the previous posts (quite entertaining)i'd like to address the safety issue again. I read the ATPA rules that were posted,and noticed no reference to the bellhousing. I personally think they missed the boat on this one,and are lucky they haven't had any incidents at an event. After seeing first hand what a clutch looks like when it comes apart and goes straight up and out through the firewall/base of the windhield. The driver was lucky he wasn't injured. I wouldn't even think about running a puller without either a scattershield or a blanket on it. It's not only for your protection it's for the spectators too. What will the ATPA do when they have an incident,and thier insurance carrier raises thier rates (already rediculous)especially in a class that is still new. I think we all know the answer to that. Back in the early 80's the dragstrip at Union Grove WI had a car that blew the clutch,and the disc came down in the crowd. There were 2 people killed 20 feet away from my sister & brother in law,not pretty. Just my . 02 (and then some).

 

[Sled Puller]

Don, Don, Don! What are we going to do with you?



The Pros tell me lots of things that don't get repeated out here, and they never told me to run 28 degrees on the street.

I can't give all the secrets out.



Now don't you fret about that 5-30, it will take care of my rod bearings just fine, like it did the first 100,000, as soon as I get that nasty ol thick,stinky, Delo out of there.



Excessive Force,

Point well taken on scattershields, but what was the vehicle you are talking about that scattered and blew?



Was it a street Diesel under 4000 rpm?
