okay, here's the scoop, a carbon fiber or aluminum ONE-PIECE driveshaft is going to cost me $1500 to have prototyped. this will be a huge benefit to our cars for for E.T's and reliability by eliminating the carrier bearing.
the cost to all of you should be much less. more to come on that part whenit's completed.

we are also now selling High-stall torque converters for $600. if we have group orders of 5 or more, we will sell them at $550. these will have a 2600stall for reliability and driveability.

 

How many miles have you ran your new converter? any improvements at the track? what are your temps after this new converter. Anything much hotter than stock tempature and i would consider mounting a transmission cooler. Remember HEAT is the number one killer of transmissions. is this the same unit as the LET one or by a different company? sorry for the million questions. Oh and who is "we"?

 

What would call our stall now? Iam afraid that the tires would just be blown out of the water at 2600, good info but Wanna know more. Are these built on MB cores ?Woody

 

MB cores.

these are 'lockup' converters, so no extra heat will occur from 'converter slip'

these are being built by a racing engine/transmission company. decades of experience.

 

how do these or will these compare to the one that LET is now offering?

 

Not sure, less money....?


I don't know enough about LET's to say.

 

They are going using the same materials for V8 drag-racing converters in cars making over 750hp.

they make over 1,500 OEM converters a week!

what is important is how loose the stall setup is and how FAST it is.

 

Subscribed.
Awaiting more detailed information as I'm sure others are.

 

GREAT, we need to know how many people are SERIOUSLY on board to get things rolling.

 

I'm listening...ran a stall back in the day on one of my Camaros...so I understand the concept, but with Traction Control, and such, don't know how they will work...even with TC off, it still will over ride...does this need to be added to our custom tunes to make it work best? just asking...price is good, thats not a problem...

 

Price sounds good but I'd like to see some testimonials before I buy.

 

I would be interested.

 

I think you would have more people willing to jump on board if you already had it installed and could vouch for how it works. While the price is really good, this is not the kind of part you want to find out after the install that it doesnt work right. Messing with the tranny is a big deal and if your like me and know nothing about installing anything, you only want to pay for the install once. I am very interested, but for the above reasons is why I and most people are in a wait and see phase. Now the drive shaft I would be more willing to jump on because I wont have to pay someone to crack open my tranny.

 

Nice thread, I was following a CF shaft thread over on MB world. Nice to see someone getting one in the works here.

 

Never heard that a solid shaft performs better or leeches less power than a split shaft with a 'carrier bearing' as you call it.

Didn't the MB engineers put that in there for a reason?

Not trying to be a pain, I just don't know enough about it. A little research reveals that the reason for two piece propeller shafts, as they are properly called, is that at higher RPMs they produce resonance that can compromise the shaft. This has been the big push behind composite one piece propeller shafts.

So, is it because our propeller shafts are a smaller diameter that they require the two piece design? Is it because it's a weight savings? i.e. - two piece is less spinning mass than a single piece?

Seems this article says that two piece designs are heavier, louder and cause more vibration, but don't say why they are used except that the diameter of the shaft is smaller and can't be one piece.

Inquiring minds want to know...

 

Depending on price I would be interested in just the CF driveshaft. Also would need to know the total weight CF vs. OEM and amount of power it can withstand(I know CF is generally stronger).

 

This article is pretty good. It pretty much says that if your [drive] shaft ( ) is 51" or longer you should be looking at a 2 piece. Anyone put a measure on theirs?
