Yes, our race car has stock front axles in it still and use to have DSS Stage V's, now it's an 8.8

My RS is running 9.4's on stock front axles, stock rear axles, stock rear diff, stock driveshaft, stock t-case and a Bushwacker Stage 1 trans

 

Devo Tuning has a custom 2 piece driveshaft that we have been using for almost a year. It is chromoly tubing and shaves off 14lbs of weight from the stock driveshaft. These things are beefy and WILL NOT break. Best of all its only 550.00!!!!

Why do they want our core ?

 

Taken from the ACPT website.

ACPT carbon fiber driveshafts provide a special measure of extra safety. Despite safety hardware like shaft hoops and covers, a broken metal driveshaft can become a flailing bludgeon that beats up everything in its' path; severe injuries to the driver, extreme damage to the car, and even vaulting the car into the air can be the result. Carbon fiber minimizes these dire consequences.

Carbon fiber driveshafts are built for strength primarily to transfer torque and can be broken with a hard blow from the side. The result is that when a u-joint or yoke fails the carbon fiber composite begins to disintegrate when it contacts the chassis or driveshaft hoop. As the composite comes apart, the shaft simply turns into a bunch of loose carbon fibers. much like the end of a broom . In fact, in composite technology this failsafe state is called "brooming". Instead of tearing up the driver and shredding the chassis, the carbon fiber broom will probably just polish dirt and paint off the chassis.

Racers race to go fast, not to cheat death and disability. ACPT is very proud of the fact that our driveshafts have helped to prevent serious injury on several teams, like Dick Anderson Racing. "I have two talented, young drivers to protect," Dick Anderson explains. "Both have narrowly escaped serious injury when metal shafts broke and penetrated their cars. Last season, a bracket came loose, destroyed the torque arm and broke the ACPT shaft in two; but it never came into the car. It "broomed", just as they said it would, and no one was hurt."

 

The Devo piece is resonable for that amount of weight being lost, I didn't know anything like that was available.

I had the very first ACPT driveshaft ever built for a 1g DSM. Long time ago, I think back then it cost me around $850, which at that time was big money. Hell it's probably been 15 years or close to it. I remember being sold on the weight savings and how much faster the car was going to be. At the time the car didnt gain any ET/MPH. John Shepherd bought that car from me with that driveshaft in it and a broken rear differential, I think I recall him eventually breaking it but I could be mistaken. Who ever I remember breaking one it did bust apart and "explode" rather than busting through the floor of the car.

 

Isn't stock a 3 piece. A couple people said it was 2. Not sure.

 

I'm sure to reuse the hardware... they probably only replace the tubes, and obviously delete one joint.

However, at their price point to weight reduced, I'd say that this is the best option currently available... provided it proves reliable enough. I'd like to get my hands on one and find out!

 

I heard AMS uses a carbon fiber drive shaft on their time attack car, and said it improved their times...

I cant find where on here though...

 

Any deletion in rotating weight is a plus. If it's worth 2.6k is up to you though Sort of like a Tilton twin carbon....best clutch hands down, but it's also 4k worth clutch!!

 

expensive

 

I have one of those driveshafts from DEVO coming my way, probably this week. When I get it I'll do a seperate write up on it and let you guys know what I think.
For the money vs weight it seems like the best thing going and eliminating one u-joint is also very good.

This thread ended up working out well

 

great, cant wait to read it

 

Keep *** comments to yourselves guys and keep us moderators out of your posts.... follow?

 

I'm discussing picking up one myself
