I know the driveshaft is a two piece or three piece...whatever! My friend changed his in his GTO and what a difference to power to the wheels it made! Can we do this mod and what are the negatives to doing it? I am surprised to have not heard this question yet on here but maybe I missed it. Looking forward to the replies and answers! Thanks in advance!
One piece driveshaft

You can have a custom driveshaft made. I don't know of any companys right now selling anything driveshaft related for the Vs. BMR used to have a one peice carbon fiber, but I beleive they said that they didn't sell any. So they discontinued it.
I am wondering why no one has done it and will it interfere with the independant suspension? I can't explain how much my friend said it did for more power!
Well one reason is that it's not cheap, and theres really not much power gain from it. It would help with driveline clunk, but that would also make the rearend see that much more abuse. Plus BMR stated that their shaft was to big to be used with the factory resonator, and while that doesn't bother everyone, it will hurt some of the sales. Add that to the already low number of Vs, and you don't have a very good business case.
I agree, after talking to a designer at Inland Empire Driveline, he said over $1,200 and a small gain in RWHP.

·bmr had problems with it. a certain part where it attached to the tranny kept breaking and they could not resolve the issue so they just dropped it all together
I think I started a thread about this a month ago but do not recall the answers and reasons why a one piece driveshaft will not add power to the wheels? I would like to hear all the opinions on this please! I believe one guy commented about it not delivering much more, if any more power, to the ground! How can this be true as we are losing power to the ground from somewhere? My buddy put a one piece DS in his GTO and the Corvette Doctors, in N.Y., L.I. couldn't believe the numbers his car put to the ground and said it was because of his driveshaft! They did not do the work, he did it himself and just tuned the car there! Without getting to the numbers of his car and what he has done I would like all opinions on the driveshaft bit for the V! Thanks in advance!
I tell you i look at the driveshaft on the V and i could it believe all the stuff they connected to it. from the motor to the tran to the driveshaft their this rubber balancer it looks to me, they got three u-joints and thats just awaste of hp there. i think 3 u-joints.
Uh, why not search for it. Especially since you started it. Should be easy to find.
On a side note, did your buddy dyno before and after the DS swap?

UH, because there was not much reaction and my question was not really answered so, why look for it? But thank you for doin it! The reaction I did get was from one or two people and they claimed that it would not get a lot more power to the ground! I believe you stated that it was just too expensive and other than that, there was not a lot of reaction or answers so, I am trying it again! My friends car was not dynoed before and after as the DS was the first thing he changed and said he noticed a lot. The vette doctors dynoed it after quite a few mods and again, couldn't believe the numbers! They said that with his mods they expected 25-30hp less! His GTO has bolt-ons, which include headers, NO exhaust stock cats, and a cam and it dynoed at 422hp and 398 torque. The car runs well, trust me!
At any rate, I may be the guinea (sp.?) pig as I may get a great deal by a driveshaft shop to try it. I am debating on whether to do it or not with the feedback from you guys. I guess nobody has done it yet and that is surprising, I guess! I do not know what the great deal is yet as I will speak with him tomorrow, it was my friend who asked me if I wanted to do something like this and really didn't want to after the responses I got from the last thread! Then, I looked into more and I am deciding on trying it. I was more or less wondering:
Why we have this 3 piece driveshaft and what are the negatives to going to a one piece?
I beieve you will find as driveshaft length increases terminal speed decreases. Some of the "hotrod" trucks running around see issues now and then. It has to be one hell of a tough shaft to be long.
You might to redesign the exhaust system, it's up in there pretty tight and there's not much room, a one piece shaft will probably require more undercar clearance and the exhaust is dead in the way.
I would suspect that a one piece shaft would be slightly more efficient do to a difference in frictional losses of multiple joints and the play of a carrier bearing mount but it's going to be a trade off for ground clearance and other factors on a V.

The only way I can see it putting more power to the ground is by being lighter. Less mass to rotate...just like lighter wheels. Isn't there already a carbon fiber alternative out there?
Now, this is why I asked this question again because now I have many more answers! The driveshaft must be bigger you're sayin and it will need more clearance, the exhaust will have to move too, maybe! Sounds like a nightmare but I will call this guy and get more info. and get back to you guys ASAP! Thanks for the info. it's a lot of help!
Anyone know what driveshaft set up the CTS-V race teams use? That may be a clue to the relative advantage if any.
