I take it your going carbon fiber since the chart doesnt go to the length you want? in this link an aluminum 4" can take 2k hp and this is what Mark williams wanted to sell me 1st at my length so at 1/2 the $ of cf this works for me even with shipping 50$ maybe. aluminum ds spec from the link"Description 3.5″ Shaft with, 1350 Series “Gold” Cryo treated Solid U-joints, are built under the most Stringent Tolerances in the industry. Tubing is Factory Straightened to .010″ total runout at the center of the tube. Tube yokes are welded to within .006″ runout on each end. The shafts are Electronically Computer Balanced to less than 1/8 Oz/Inch, as an assembly, assuring smooth operation at the Big end as well out of the hole. Critical Speed is calculated on each shaft to insure your Safety and Ultimate Shaft longevity. We recommend the 3.5″ shaft in most cases to 1000 Horse Power. 4″ Shafts are recommended to 2000 Horse Power. Shafts are complete with the most common standard transmission Slip Yokes. In some cases an upgrade on the Slip Yoke or U- joints may be considered."

How about chromemoly DOM 3.5 tubes? In the chart the rpm limit is much lower for cm.My driveshaft speed would be 6300 I think at 140 mph.I have some hard choices to make here it looks like so I need to revisit the data

So I would have a ds speed of 6266 with a mph 140 and a 28" tire and 5848 with a tire of 30" so with a 30" tire I think a aluminum 59" shaft is doable.Or even a 4" mild steel

Did you use this calculation for the ds speed? Top speed x 336 (a constant) x rear ratio (like 4.10), then divide it by the tire height (28” tall tire) It doesnt look like it yes I did w 3.73 gear so 140 mph 3.73, 30" tire

Tex I think you could make a solid tube work but why dent the floor when you can form the tube?.My Lokar is about 34" long
