I can get a cinder/iron/brass dd clutch made to hold over 1000 hp and hold to sled pulling and is very street drivable, for $600 bucks. This guy invented this clutch his self and also said it uses the stock hydralics also. While I am at it I am going to get a full flywheel to replace the dual mass, and I think I am also going to get a hydralic up grade get. what are your thoughts on this clutch and have any of you heard of something like this before. This info is going from the shop manager at my dealer because they do performance mods also and this is what he found out
 
That's DIRT cheap for what it is.

Lot's of people will tell you to go with a proven name, and I'm not saying that this guys clutch is as good/better/worse, but at one point no one had heard of any of the big names. Innovation and good parts can come from lots of different places.

With that said, if it doesn't hold/last, can you deal with the cost of another clutch, and more down time?

Just my $.02
 
well for the price of this I can get three compared to 1 sbc dd 4200 which I was going to go with so I think will try it out and see how it does and for as cheap as it is it works good for I know the guy will gain a lot of my business thru customers
 
The other limiting factor is going to be SFI approval. Most that are going to be pulling are going to need that.
 
I dont know the guy but ive been hearing things about these clutchs. Any contact info or more info on the clutchs?

This is very important! While it may be cheap will he ever make enough profit to get it certified?
 
the other limiting factor is this guy probably doesn't realize that 1000hp in a gas application and 1000hp in a diesel application is a difference of about 1000ftlbs extra torque.

my bet is it's going to fry on the first hook

i will try to find out tomorrow if it is certified or not and see if I can get some contact info but that would make sense if it is not certified as to why its so cheap but I know he builds them for sled pullers this is just the best clutch that is still streetable he can make better ones but they cant be driven on the street . what other questions do you think I should ask

he makes them for sled pullers around here in utah/idaho
 
ahh, cool... I thought it was someone who builds clutches and decided to try to break into a new market

I'm sure they're like an on-off switch, but that's a heck of a deal for something that'll actually hold that kind of power!

exactly why I wanted to get your guys input seems way to cheap, cheap enough if it dont last I wasnt out much
 
yeah, might be worth a spin!

it's "sintered iron" btw ;)

I'm just curious how he's going to hold that much torque with a single disk and a pressure plate light enough to use factory hydraulics :confused: no matter what the friction material... sintered iron is tough, and the nice thing about metallic clutches is if they start to slip, you can back out and not really lose any holding power, but they'll really dig a trench in a flywheel if they start slipping and you stay in it! :eek:

Reading your post I see it is for the clutch only and you are going to have to get a flywheel. From our experience, this is where the money comes in. We have a little over $600. in the flywheel with bronze inlay alone. Now with the cost of metal on the rise, the cost of the raw material for the flywheel and center plate has almost tripled. Our country has got to STOP selling all of our metal TO THE FORIEGN MARKETS. We also have to send two complete units in every year to get destroyed for the SFI approval. Ouch! As for the original question on materials. We buy over 6000 ceramic buttons and 2500 feramic buttons a month. The sintered/feramic buttons run us $10. a button. On the dual disc we use 48 buttons, triple 72. Not cheep and I think we have a little buying power. As for the hydraulics and your truck, it is not that they are not heavy enough (they really aren't LOL), it is the design and stroke of the unit. The OEM pressure plate in the late models run a self adjusting designed pressure spring. This requires a very limited throw and does not need any return or adjustment for wear. If you go with this guys setup I would suggest changing the hyd. If you want to save more money and HD hydraulics are not needed, don't use ours. Instead, get the OE hyd. from a 04 truck, they should do the trick.

Good Luck

sb clutch, he will be getting in some luke flywheels that I will buy also since you guys wont sell just the flywheel, also I am going to purchase your hydralic upgrade even if not needed, it wont hurt nothing.
 
Found out alittle more info and got the guys number that actually builds the clutches but he is out right now. As for pressure plate load it is factory specs and instead of having buttons it is a full face and he was unaware of if it was sfi certified or not

Peter I think it was very professional of you to step in and offer the information that you did. :clap:
If this pressure plate is stock load it will not hold the power. If he's unaware if it's SFI approved or not trust me it's not.
Save your money and buy the real deal. I can say from experience that SB will stand behind their product.
