Top speed with one piece drive shaft?

Top speed with one piece drive shaft?
Hey guys, I'd like to get a ball park idea of my top speed, but I'm obviously not going to go for it. My car is pretty far from stock, but I'd appreciate any ungoverned answers. I'm at 470 wheel with 3.73s, so I know the answer will be different but I'll still get an idea. Thanks

4th gear will top out around 135, which should be no problem at all.
With that torque it should pull 5th from there with no big problem. . . up to maybe 160-170 or so where it will become drag limited. I'm just guessing, don't really know.
But of course that assumes that you have removed the factory speed limiter, which I'm pretty sure is set for 145.

6000 RPM in 5th gear with 3.73 rear gears and the normal 27.2" diameter tires calculates out to about 190 MPH, but it will be drag limited before that for sure.

was the question about theoretical top speed, or critical speed of the driveshaft? just asking as theres video/stories of v6 driveshafts hitting critical speed and blowing apart at around 130-135 mph, around 5500 driveshaft rpm...(3.31 gears/27" tires)

Just theoretical. I only specified "one piece" because I'm aware of the drawbacks of the two piece and I didn't want people wasting their times writing up an explanation of that issue haha
