What are you running for a driveshaft
 

Since the driveline is all custom I need to start looking for a shaft that will handle the hp and torque of my FE and the sustained rpm.

So for 700hp and 150+mph what do you run for a driveshaft. AL, steel, CF?

Anyone use these guys?

How about inland empire

http://www.iedls.com/

Anyone have any good or bad driveshaft vendor stories to share?

Both companies are good. 3 /12" Al should do I think. But what do I know...

(don't anwser that!)

:cheers:

Ron, I think he might need larger than 1/4" (=3/12") :lol:

But the 1/4" is so much lighter.......:lol:

Yer both right!

Hurst Drivelines used Inland as the supplier for my conversion. They exceeded all expectations. I had the driveline within 7 calendar days of submitting my measurements.

We all need banned and HELP. :lol: I'm running a 3.5" Aluminum from Inland and it's hanging in there fine so far.

I run a 4" Carbon Fiber driveshaft from Mark Williams. Super light, less high rpm vibration and stronger than aluminum. One good advatange (hopefully it never happens) is that if it fails, then it will shatter rather than poke threw the floor. It's rated for drag launches and high driveline rpms.

Inland Empire Driveline :thumbsup:

Dennys, you ever break it they will replace for free and they will shorten it for free.

I've had several done from Inland Empire. Always excellent quality, and always on time (about three days from ordering to delivery for me). The last couple were 4" aluminum, have done 3.5" also in the past.

Dynotech from Troy Michigan did my last one. Excellent quality and very quick. Kyle from DSE recommended them :thumbsup:
3 1/2" Aluminum

Accu-bond aluminum drive shaft from Mark Williams. Great service and turn around time.

My 3" aluminum DS is rated for a critical speed of 9374 rpm and a torsional yield of 3633.75 pound-feet.

And yes I stayed at a Holiday Inn Express last night.

I was looking at that Raj. What exactly is accu-bond?

Yeah, but did you eat at Denny's? :D

PST carbon is what im purchasing.

Hey Ron -- from what I was told is that the aluminum matrix (Duralcan MMC aluminum) used in the Accu-bond drive shafts is not "weld friendly" but stronger than 6061. The guys at the shop swear by the Mark Williams stuff. Here is a quote from their site:

Accu-Bond driveshafts utilize the Patented (7,485,045), end fitting bonding process that much stronger than conventional welded shafts. The end fitting are produced from 7075 forgings 50% greater strength that conventional welded fittings. The result is a stronger and more accurate running shaft at a reduced cost compared to the Aluminum and Carbon Fiber shafts.

Just technical enough to make me try it...:cool:

I had Inland Empire build my drive shaft. It took them two tries and they still didn't get it right so I had a North County San Diego shop (Oceanside Driveline) fix it due to time constraints. I seem to recall this happening to Rupp once and they fixed it on their dollar, no hassles or anything. If I was local to them I wouldn't hesitate to have them build another drive shaft for me in the future. I want to think I just had bad luck.

How much is that going to run?

What was the issue Matt? Just wondering? Length? Balance? Yoke?

right around 950. Mainly for saftey... because I do not see the driveshaft exiting from under the vehicle at a 3.5" ride height... "just in case" there is also a loop.



Now see the problem I have with aluminum shafts is when you weld 6061 if I remember correctly the joint and HAZ area is weakened by 61% or so.. IF remember correctly don't quote me if Im wrong.

Matt

started with dennys and they will shorten for free, but with shipping both ways and their materials charge it was still running me over $100. great guys and if i was closer i wouldnt hesitate.

socal though is a different story. after needing work done i took it to http://www.drivelinesinc.com/. i havent run it, but nice guy, great work and he does stuff for robby gordon and others.
