I've seen lots of different ways to pull power out of a 4.0, most of which are stroker builds. So depending on your views, it's not much of a 4.0 anymore. I've been reading, and reading, and reading. The big question I've got here is to those with experience is, what setups have you ran on a 4.0 platform, what was your operating PSI, and dyno results? Any input is appreciated.

 

Just build a stroker.

 

XJ-R FTW.

Stroke it then blow it

 

Yes! home of the most powerful inline Jeep motor

 

What is your budget and what is the intended use? Dyno runs, mall parking lot, or something in the real world?

Ahhh so the Ford Ranger 4.0L V6 is the same engine, right?! Cuz it says 4.0

 

I've seen a lot of 505 but have never personally taken a look.
Budget hovers around 3k... And looking for something in the real world. This isn't some whacked idea to turn a lifted minivan into a race jeep. I want something functional, but dang nabbit I want some real power.

 

If your looking for max power ls1 swap it.

 

Definitely not 505, so many have had bad experiences with them and problems.

Check out here, I have many dyno runs and power upgrade within your budget.

The next Cherokee is going to get that side mount. Extremely excited to see this on the market again.

 

Lol

I've narrowed myself down towards the HESCO supercharger. Has anyone worked with them before? There website is less than... User friendly.
