All,

I'm working on an Opel GT for a local stick shift class http://prostickracing.com/

Should be 2400 -2500 lbs. Typical 377 sbc, GF2000, Boninfante 10" single. Dana 60.

30" center to center. Would a CF shaft need to be 3.5"? Smaller would be better as far as clearance at the main hoop bulkhead. The DS and I will be cozy. I'm going to use a full enclosure, but it's still a little unnerving. I'd post a picture, but I mustn't be allowed to. There are pictures showing loops and such in my "garage" here.

I do have a nice steel 3.5" with 1350 joints from another race car that I could shorten.

Thanks.
Dave
PMs welcome.

I have been running a Dennys Driveshaft, one of their 1350 Nitrous Ready 3" versions with Mark Williams slip yoke for 5 years with no issues. My car is also a stick car much heavier than yours. See signature.

If you want the best, you call Mark Williams and their slip yoke is made by Dedenbear

Thanks Gents,

I have a rapid release MW yoke. It'll allow me to R&R the driveshaft from the trans and slide the trans back for clutch maintenance w/o removing the driveshaft from the rear.

My main area of question is can a carbon fiber shaft [30" long] be "3 or even 3.25" for my car?

My QA1 is 53.75" and 3.2" in diameter. Rated for 2000

Thanks, mufflerguy,

I see that they also have 2.25".

Just for someone that is searching for info:

QA1 can do 2.25" for drag race with 1310 or 1310 to 1350 joints, but would be limited to 750 horse/500 lbs-ft max.
