Driveshaft Speed

[abc]

Fabricate a hole through the middle of the fuel tank to get to the frame rail? There's no other access to the driver's side.

Probably would be easier to move the tank, but you do you.

Yes, a fuel cell in the cargo area of an otherwise-stock-appearing street driven GMC Envoy. Or, change to a 3.08 gear with the current tire size, or 3.23 with a taller 30.8" tire, and a commonly available 5" OD driveshaft (critical speed 5700, which with current gear/current tire gets me only to 125 MPH).

Compare all that nonsense to if anyone just made driveshafts with 6" tubing, same tires same rear gear no changes other than the driveshaft, would take it to 152 MPH.

(I know what 'fabrication' is, numpty)
