I ran my 2dr at Bonneville with 37's. While I didn't feel like I was going to die, I also realized that at 96mph, you really won't have any opportunity to correct for any unexpected circumstances. (I guess the 392 gains you 3 more mph , so that's not nothing, lol).

We have to assume that the only way Jeep was allowed to put that engine in a wrangler, it would have to come with some crazy restrictions.

Best bet is to find a shop that works on challengers, etc and see what they say. Anything is possible.

I am sure its one of our useless laws but why not available to California? Was planning a trip out to Hotel California and want to kick it up on the dark desert highway. I can sign a release or track use only.
Because this is not emissions legal yet. we did just get 11-20 6.4 covered in basically every application, but 21 is not yet coevered.

on the 19, I sort of agree, but this you're doing 80+ with feeling like 60-65 in the MOAB we have.

I picked up my new 392! It is the most stable Jeep I have ever owned! I have owned 83' CJ5 , 85'YJ, 2014 JK, 2016 JK and now my 2021 JL 392. I can't say I was impressed with the price but this Jeep kicks ASS!
99 MPH comes up pretty fast when on open stretches' but seems like they could have left the speed limiter off completely! Handles like a Audi. Hacking is required !!

I consider myself a fast driver, but I don’t have any desire to drive my 392 above occasional bursts to 65-70! It pretty much handles the same as other Wranglers at speed, just louder.
