Any insurance guys think he could claim that?
Ive been wondering what RPM that engine saw (briefly). Does it really come out to 50,000?

His math is a bit off probably, but it’s still crazy.
An auto has a 4.71 first coupled with the 2.72 low range and I chose the middle ground 3.73 (3.45 & 4.10 are also options) and that put it at ~34,000 rpm at 65mph. Worst case scenario with a manual first gear of 5.13 in low range with the 4.10 rear puts you at 50,000rpm at 80mph so I guess it’s possible. This is all calculated using a 31” tire.
Ninja edit* Just saw it was Rubicon so figure 33” tire which will lower the rpms a bit. Still agree that the crank/block exited stage left very early in the process before it ever saw those rpms.
Recalculate, the Rubicon comes with a 4:1 low range.

Did not know that, guess it started in ‘18? In that case 50k would be 70mph with 3.73 and 64mph with the 4.10.
Either way it is a moot point as there is no way the engine ever saw even remotely close anything over 10k-12k as stated earlier. Rod bolts, rods, wrist pins or crank probably let go somewhere before 10k I would bet after the valves had floated for a few and beat the hell out of the pistons. If it could have held on them theoretically it could achieve such speed I guess.
Now we find the gram weights and calculate rotational mass versus tensile/stretch/shear values and we’re getting somewhere. I’m sure stocks specs are absurdly low in comparison to what it would have to endure.
Rubicons have had the Rock-Trac 4:1 transfer case since the model debuted on the TJs. All have 4.10 gears too.
