Welcome and thanks for the update.

Congrats and great write up. Too bad about the paddle shifters. Looks like the Ram TRX was better implemented from reviews I’ve read so far.
Does the front axle have the Front Axle Disconnect delete on passenger side or is it solid from dif to knuckle?

This is from a chatger forum for the 392, I figured the procedures would be similar enough. Did not flip through the owners manualIs the recommendation for engine break in period 300 miles or 500 miles? I have seen both numbers mentioned.
Yes I would say it is required. I would also say premium fuel is required for just about any performance engine. OEMs can either dumb down their tune or lie and say any octane level in acceptable, that's basically it. Higher octane increases knock resistance, allowing a greater window of "safe" performance levels. The higher the octane, the bigger safety window allowed in the tune/build. Anything that is running aggressive timing or high compression requires high octane.I heard that premium fuel is REQUIRED not just RECOMMEND. My Mojave runs about 16-17mpg. So I've been keeping track of fuel the past 4 weeks to get an idea what it cost as a daily driver. Thanks for the info.
Yeah no problem, I will probably end up creating another thread. Its basically a tedious process of adding mass, adding material, and decoupling. I will use the Hotheads headliner for sky one touch, about 120 square feet of SoundSkins pro plus mat, some closed cell foam, some spray in acoustic material, tesa tape and a bit of rtv.Congratulations on your purchase! Green is stunning on that vehicle.
I am very interested in learning about how you go about deadening the sound, what products you use for it, etc. When you start the process, I’d appreciate it if you’d give updates on that process.
do the 37s fit with no rubbing etc when flexed?You’re mileage should come up, I’m getting 12.7-12.9mpg on 37” KO2s.
they may not have sensor for octane, but they use knock sensor for the job. when lower grade fuel is used, a detonation, Knock or Pinging will occur, ECM retard the timing and trim for fuel, thus less power.Now that I'm thinking about it, I suppose it's possible that some OEMs may use octane sensors and be running multiple tunes like a flex fuel setup.
A couple comments/questions:Hey everybody,
I just picked up my 392 and wanted to make myself available if anybody wants any questions answered. I have backgrounds in mechanical and audio. I'm not quite yet at 200 miles and I plan on properly breaking the 392 in, so no track times or performance date yet.
Here's a few things to get us started. The power delivery is a riot, on the jeep suspension it flexes hard at any amount of decent throttle. The ride is softer and more forgiving on the road than my JT or my JK, by far. It is incredible smooth. The seat bolsters are indistinguishable from my JT rubi, in terms of comfort or feel. The paddle shifters are basically novelty only, shift times are in excess of 1 full second. They remind me of the shifters in a CVT civic. They do not allow gear jumps either, i.e. 8th to 6th. It cycles through each gear slowly. That said, I am not going over 4500rpm or half throttle right now, so maybe they come alive under higher pressure.
The exhaust button is awesome and it remembers your last setting. Want to quiet down before coming in to the neighborhood? Your 392 remembers that in the morning. However, as others have stated, cold start is always loud for atleast 3 seconds. The initial rap of it starting is quite satisfying. The idle on this car is also very satisfying. The rhythmic rubrubrubrub is reminiscent of some deliberate cam lope or idle overlap, but not quite. In quiet mode the exhaust is remarkably quiet. Under 2k rpm it is as loud as my JT was. In quiet mode the exhaust will open automatically if you give it some gas.
No auto start auto stop. Backup camera is dog. This is my first sky one touch and it is great. Far quieter than I though and completely acceptable K02 noise levels. Runs about 2db higher than my hardtop JT. Full sound deadening, spray in and mat coming soon if anybody is interested.
That's all for now but if you guys want measurements or pictures or whatever, just ask. Have a good rest of the weekend!
