I remember that a few months ago - you were offering a group purchase for Carbon Fiber Half Shafts... I recall that there weren't enough people for that group purchase... How much would be the carbon fiber half shafts (excluding shipping because I would pick them up)...
What's the weight difference between the carbon fiber halfshafts and the stock halfshafts? How many HP/Torque are those halfshafts rated?

Thanks in advance!!

When I first read that line I thought you were asking how many HP/Torques the halfshafts would add to your engine :lolg: :lolg:

Well - they actually should add power.. but only rear wheel horsepower because of reduced centrifugal weight... but my question was reagarding how many HP/Torque the halfshafts can take...

Hi Olivier,
The carbon fiber half shafts can handle a lot of HP. It's going to take well over 1200 hp to da any kind of damage. I'm going to look in the archives to get the weight difference. I can't remember right now but i will post again to let you know. The shaft will be $580 for you since you'll be picking them up.

Van Steel

They seem to be lost in the archives. I just weighed a stock shaft w/flange and u-joints and it was 11lbs. If i remember correctly the carbon shafts are 7 or 8 lbs w/flange and u-joint. I'm having more made and i'll have them ready on monday so i can give you a definate weight than.

:cool: :cool: That sounds great!!! So - when are you going to have them in stock??

Could you guys also have some custom carbon fiber driveshafts made?? If yes- how much would it be? (mine is shorter than stock (approx. 26" - almost as short as a half shaft) because I use a Temec TKO transmission)

Yes we have carbon fiber drive shafts also. They are $630. It may be a little less because of the length. I need you to measure from center cap to center cap to get the correct length.

GrandSportC3

I might only get a chance to measure the driveshaft on the weekend....
I will let you know the measurements...

How long time does it take to get the driveshaft built?

GrandSportC3, Don't these look great? Van Steel, Great work. Rod

The u-joints are solid spicers - right?

Van Steel

Of course they are solid spicer joints. Come on Olivier, you know how we do things here. :D Spicer Solid joints and new Spicer flanges and they are cryo-ed. If you get me dimentions I can probably have it done w/in a week.

GrandSportC3

I will try to get the dimensions this weekend.....

I would need one conversion u-joint for the driveshaft.. I don't know if it's available as a solid Spicer.. The yoke on my Tremec is 1350 series and the driveshaft is either 1310 or 1330 series... This means that I would need either a conversion u-joint that's 1310 or 1330 on one side and 1350 on the other side OR a driveshaft that accepts a 1350 u-joint on one side and a 1310 or 1330 u-joint on the other side so that a 1350 series u-joint can be used between the driveshaft and the transmission yoke and a 1310 or 1330 series u-joint can be used between the differential yoke and the driveshaft... Don't know what would be the better option...

Since you drag race a lot i would stay w/the 1350 on both sides. The only thing is that the conversion joints are only greeaseable joints. Are you using a bolt on slip yoke?

GrandSportC3

I have the standard yoke on the differential side and a "Take apart" Mark Williams C6 yoke on the transmission side. I don't want to change my yoke on the differential side..... so my best option would be to make the driveshaft accept 1330 series (?) on the differential side and 1350 series on the transmission side.. That way I can go with solid u-joints on both sides without messing with my differential yoke...

Van Steel

We can do it that way also

GrandSportC3

My main concern is cost.. I wonder how much it would cost to convert the differential yoke to 1350 series so that I can use a driveshaft with 1350 series u-joints on both sides....

Van Steel

To change the diff yoke to a 1350 series you looking at $100 for a cast yoke and $150 for the chromoly yoke. They chromoly yoke is stronger also thats why there is a big price difference and i will change it for you for $75 if you bring it in. Changing to the 1350 would be your best bet. Your going to get an expensive carbon fiber drive shaft. You'll want it to hold up. I just don't think that 1310 joint is going to do you justice in the long run.

GrandSportC3

I think that I want to go with the strongest possible setup...

Van Steel

Hey Olivier

Got some numbers for you. Carbon fiber drive shaft weighs in at 5 1/4 lbs w/out a yoke.

1/2 shafts weigh in at 7 1/4 w/u-joints and flange.
