Supercharged 2020 Jeep Gladiator "Popeye"

[JTdiRtyD]

My install was done by a local shop and the final tune was completed by magnuson.

Did Maggy actually dyno tune it, or was is just a base flash that came with the kit? If the latter, I would recommend looking into getting an actual dyno tune. There are plenty of horror stories out there, both in the Jeep and Toyota communities, about the supplied maggy tune underperforming and even causing engine damage.

The "premium fuel" thing is a little misleading.

First you need to understand what this premium fuel is actually doing and why you need it. The higher octane helps against preignition, which really is only a problem under wide open throttle loads. Under normal cruising conditions you don't need max octane. But even then if the engine control systems are working properly you'll never get into preignition anyway. The ECU will retard timing and adjust fuel mixture based off a variety of sensors and data it receives. Premium fuel or not, you should theoretically never get into preignition anyway. But that extra little bit of octane might help lessen the auto-detuning the vehicle computer will do under boost or high engine loads.

The rest of "premium fuel"? Additives and bullshit we don't really need.

This is true for the most part, but "tuned boost" can be more sensitive. On a factory F/I vehicle you can get away with running pretty much any grade fuel. The ECU can compensate quite a bit because manufactures know not everyone is going to know any better and will run whatever grade is cheapest. Adding F/I to an originally N/A motor it becomes much more important to pay attention to the fuel you run because those tuning tolerances are much tighter. A SC on Jeep might not be crazy tight for tolerance, but with the issues I've read from others that have charged their 3.6 I wouldn't take any chances.

I had a 03 G35 that I boosted and was tuned on 93. I could usually get away with 91 depending on where I got it, but if I ran anything less I would see bad detonation and power loss with even the slightest increase in engine load. One trip I was in the UP of Michigan and could not find a station with anything over mid, which IIRC was a 90 rating, so I had to run it. I had to baby the ever living shit out of that tank of fuel. Even at cruising speeds the smallest incline hills would cause detonation and power loss. Thankfully most of that tank was flat with very few stops. Granted this was a built engine and tuned for high boost on 93.

Sport Max Tow is over 7000.

https://www.jeepgladiatorforum.com/forum/forums/forced-induction-aftermarket-supercharger-turbo.42/ Yes Rubicon is rated to 7,000 towing capacity. With a CGVWR of 12,450. However unlike max tow the payload is only 1,100 lbs! Remove the lower 10% tongue weight at 700 lbs, only leaves you 400 for passengers, gas, weight distribution hitch and all supplies! But 10% is the minimum, that’s only recommended on lighter than max trailer weight ratings, use the 15%? You could not even sit behind the wheel and be legal! Of course you are allowed up to 12,450 CGVW, so how all the extras in the trailer if not over 6,600 lbs to stay under the combined gross weight ratings. All that is a bit much with the 3.6, that will spend a lot of time in the 4,000-6,000 rpm range, all that is only with an automatic!

I am sure that it was not a dyno tune … I think I will fined a shop that can dyno tune it for me just to be sure! Thanks for the heads up!

No warranty that I am aware of … I guess I could have changed the gearing but to be honest I was just digging on having the extra horsepower! I have been told that there is a chance that the internals could be at risk but I added the supercharger at 27000 miles and I am rolling up on 41000 now with not a hint of trouble!

they claim warranty on their website. the Kit is like $7600 plus installation. Did it really cost +7000 to install? Magnuson also has installers doing same day installs. Just curious.

If its a same day install it may not be as complicated as one might think and if there's no warranty or still covered is self install I would personally try it myself LOL.

Sounds super fun!!

I did it in 2021, and thought it was a waste of money. No noticeable power vs stock, it felt slightly quicker at best. Ended up just doing the 392 swap like I should have from the start. I’d say 75% of the S/C owners end up doing the 392 swap, so just start there.

That being said, I had zero issues even though all of the "I read it online" experts kept telling me it was a ticking time bomb…..

Yes. To me it was a waste of money. If you think yours wasn’t, that’s fine. How long have you had one? Who did it?

In the end it’s whatever you prefer! If you do what you feel is good with you, and if it works for you, my thoughts are that what others say about the decisions you make for yourself are just their opinions! In other words if you love or even like and are satisfied with your choices … revel in them and don’t let anyone tell you different! There is no perfection here and nothing is going to last forever, the star that burns brightest burns out sooner and all that stuff! Your pentastar supercharged or not will last for however long it is going to last! So will your 392’s. Probably in 10 years you won’t even have the thing anymore anyway! But for today … hey guys enjoy your gladiators however you choose to power them they are some awesome looking rides! And some of you guys have a knack for outfitting them that is way cool!
see you on the road!
