In a 1/2 hr on Spike, Extreme 4x4 - Supercharged JK part 3 will be on. That would be 10am eastern time.

 

Watched it, was good to see. Wish that could've been my rig. Hah.

 

Saw it too. That Hemi seemed a little weak.

 

I wish there was a comparison on the same vehicle. Kind of an unfair comparison.

With the RIPP SC what kind of engine longevity are we looking at? Are they good for 100K 5years under normal to hard driving like a V8 would be? The SC is only 5K so you definitely get your $ worth upfront. If the stress causes the other parts to go bad that might cause you to spend another 10-15k on parts and labor.

What do you guys think?

 

I would like to know how many miles and what kind, if any, issues people running the SC have had.

 

I agree. I was one of the Hemi JKs used for this. Didn't get on tv, but did get to do some pulls on the dyno. Both the Hemi and SC numbers were lower than we all expected. But thanks to the guys at Extreme 4x4, RIPP, and a couple of Hemi JKers, we have real world numbers as to what these two options put out.
The RIPP SC was tuned as far as it would go (I think it was), and it put down some really good numbers. The Hemi's were both AEV kits, using the tune that AEV locks into their ECU. Which, in my opinion, is probably a little tame to keep everything safe.

If you look at the stock numbers for the Jeep 5.7L used with the Hemi swap, I think they are rated at somewhere around 330-345 HP and around 360-375 TQ, measured at the flywheel. The rear wheel HP and TQ numbers from this test were around 213 HP and 250 TQ. That is about a 40 percent loss at the wheels.

That would have been great. Unfortunately for us, no two JKs are the same. Unless somebody wants to build two identical Jeeps, one with a SC and one with a Hemi........ Or do a swap from SC to Hemi (or vice versa) on the same Jeep.
