Those with the Magnuson Supercharger...

That's probably very true. I think I'm able to enjoy less gear hunting and my OEM gears because I haven't loaded mine down with much weight over OEM. If I had all the OL gear and skid plates on mine I'd likely need a gear change too. If and when I add that kind of weight I'll see where I'm at. Right now, the Maggie is all I need.

 

It is not the same obviously, but it helps a ton. The problem of this truck is not lack of horsepower, Wrangler has same hp/torque but runs circles around the 4Runner. Problem is the pathetic 3.73 and 5 spd.

 

You're right the problem is not lack of horsepower, it's lack of torque in the lower RPM's. This is what makes them feel sluggish and gear hunt and that is only made worse when you add bigger tires or more weight. The regear helps mask this as it causes you to run higher RPM's to achieve the same MPH or acceleration. The supercharger address this by adding 40-60 pound feet of torque at 2000+rpm.

 

And regear helps. Yes I have to be at 2500 rpm for 60 mph. But I stay in gear going from 65 mph to 80 mph and I hardly feel it, it is smooth. Things get even more awesome on the trail. My crawl speed is low now and I love it. Supercharger is awesome but maybe OP doesn't need that much. Maybe a regear is all he wants. A good friend of mine just bought a Wrangler Rubicon with 4.88 from factory. Crazy for 33 inch tires, but he is loving it lol.

 

It's not really an apples to apples comparison when a Jeep is brought in. They have an 8 speed transmission to go along with the 4.88's so its tolerable. 2500rpm@60mph does not sound like a good time to me. I'm sure the benefits on the trail are amazing and I'm jealous, but the tens of thousands of miles I spend on normal roads going 55+ to get the places where I'd enjoy the 4.88's are why I wouldn't go with 4.88's. That's the beauty of the supercharger, it gives you power and doesn't change the RPM's we drive around at. I think the dream setup would be 4.56's with the supercharger. You get the benefits of both and minimize the RPM penalty. Obviously there's is no one size fits all solution so everything is about compromise.

 

I got both the 456 and the Supercharger! And feel still slow, J/K.

Preference guys, to be honest, the stock is fine too. You know the fact is, this is a truck and meant for slow driving and not compromising reliability. If I had to do it all over again, I would have gotten a landcruiser and be done.

 

Does this 4.0L like being supercharged? It sure is on my list of things to do, but will take me a while. Man if I could squeeze 400 horsepower out of this thing.
I have Jeep background, and the Pentastar sucks being supercharged

 

My supercharger now has 50k on it and no issues or complaints. I still love it.
