Differences in the 17-18 3.6?

[TheGrendel]

I'm putting a sprintex on my 2016 JKU right now - should be dyno tuning monday. I would never run a canned tune by itself.

Sprintex is a positive displacement blower, and unlike ripp or prodigy which utilizes centrifugal compressors, boost and therefore power gains are instant. Centrifugal style blowers have no place on a jeep IMO.

I've also added methanol injection to keep IATs and the engine cool on hot days.

my buddy that runs the Sprintex and actually likes it had access to a local shop in Houston that worked the tune for him. makes a big difference to have a local shop who can get it all running correctly. :thumb:

They’re total shit. They’re forged internals are good but their tuning and turbos are shit. A shop out near me had one and they said it was an absolute nightmare and made the Jeep un-drivable. They switched to a Ripp, did prodigy forged internals, custom radiator and dual fan assembly, and had it custom tuned instead of running the Ripp tune and they say it’s amazing.

Honestly if i could get a custom tune done on mine, I’d run a supercharger. But the remote tunes are always shit

Like I said, I don’t really know. There’s a shop local to me that turns them out all the time and supposedly it’s great. I chalk it up to ignorance though, and until someone drives a JK with a V8 in it they’ll never really know what’s good and what’s fabulous. You also have to remember people rarely are even honest with themselves when they spend that kind of money.

I don’t want to experience the supercharge but want to hear the noise. Can you point me to the spot where I can accomplish that? Strictly for testing.

Just in case anyone is interested. I put down 356 ft-lbs of torque and 330 RWHP with some tuning still left to do once I get a FULL tank of 91 octane in it.

This was on my 35" ridge grapplers.

At what RPM?

 

[feederic]

Dyno any engine and peak power/torque is made near redline.

What you want to see is a flat torque curve, which indicates power building across the RPM. Positive displacement superchargers produce reasonably flat torque curves.
