Are Supercharger Issues Entirely Related to Tuning or also Hardware?

Awesome that you've built the 3.6 to handle extra power and provide some additional safeguard!

Out of curiosity, did you run the supercharger on the stock motor first and then decide to upgrade because of reliability or power concerns? Or, did you always plan to make ~500whp from the get go?

Reason I ask is MMX mentioned they could do the Procharger kit with their forged pistons and rods to beef up the bottom end for a little less than 1/2 the cost of the 392 swap. However, I don't know that this would entirely address the 3.6's shortcomings, and I'd still be stuck with the stock manual transmission which is already subject to a recall due to the clutch and its inability to cope with higher power loads. I guess factoring in a new clutch, I'd still be at about 50% the cost of a 392 swap, but I'm wondering if I'd be twice as happy with a 392 regardless....

I did run the Supercharge for 2000 miles and it ran fine. I wanted to get more power. Since I have a stock Automatic, the top power it can handle Is 600whp (This is what Prodigy Performance told me) So I decided to go for 500whp to keep it safe.

My truck is on the plump side as well. I believe it weighs around 7200lbs with me and a full tank of gas. Steel bumpers, winch, rock slide engineering retractable rails, bed rack and basket, etc.
IDK what the 392 weighs, but much lighter. Don't get me wrong, my JT runs great, for what it is, but the seat dyno goes to the 392 hands down.

As for the 6 sp, like mentioned above, i have never seen that done. Does the diesel offer a 6sp? I'm not even sure if mopar offers a manual in their HD trucks anymore?

Just looked up the weights and a stock Gladiator is between 4,650 to 5,050 lbs, whereas a Wrangler 392 is 6,100 lbs. So, stock for stock, the 392 is much heavier. The dyno's I've seen of a supercharged Gladiator put it at about 300whp, whereas a stock 392 puts down around 400whp. That's a huge difference + the extra weight so I guess that makes sense....slightly taller gearing isn't going to compensate for a 100whp deficit and 1,000 extra lbs of weight.

Awesome, good to know! If you were talking to Prodigy, any reason you decided to go supercharger vs. their twin turbo setup?

Supercharger boost starts sooner then turbo. Since the motor doesnt like high revs I choose supercharger

Gotcha, makes sense!

and to add to that, the roots style blower (magnusson) makes power/tq at much lower rpms than centrifugal super chargers.
I have read a lot of comments about having "choppy" throttle response with the magnusson. What I have experienced is the throttle response is just fine, you are literally feeling the added tq of the truck everytime you hit a bump and your foot moves on the skinny pedal.

I’m putting down 340 at the wheels on a conservative tube fwiw

Whats your wheel/tire combo?
I know I am sacrificing a bit with 39: tires and heavy black rhino wheels.

Factory 17s and 295-70. Running ko2. Been pretty pleased with the set up
