RIPP GEN II Stage II on the Colorado Mountain Passes and Off-Road.

Here is the video of the RIPP GEN II Stage II kit on the mountain passes of Colorado. Being able to conquer the mountain passes was the reason I bought the kit and it took care of them no problem. Enjoy the vid!

The engine light and traction control light are on the entire time.

ya he pointed that out during the video, I guess its running too rich and ripp is working on a fix?

looks like its a blast to drive now, I sure wish they had put a even half decent engine in these jeeps.....

Incorrect. The engine light is only on on the way home. It is running a little rich probably because I am at altitude. I am the first guy running the RIPP 2.0 tune at altitude. It will be fixed this week. I'll keep you posted.

The ESP light has nothing to do with RIPP. I turned it of permanently.

The traction light is the OP traction override - the CEL has been forwarded to our Calibrator and will likely be part of the tune update... Our Calibrator believes it to be a false codes triggered by the rear bank O2's - it does not effect the performance.

Someone want to explain to me how a supercharger increases gas mileage and horsepower?

I've only help put superchargers on muscle cars and those just dump extra gas into the cylinders so what's the deal with this?

Superchargers dump more AIR into the cylinders, not fuel. The OP has a very specific problem int hat he is driving regularly at 8k+ feet of elevation. The not-so-stout Jeep engine is starving for enough oxygen to make horsepower. The supercharger takes care of that.

The Roots type blower will never increase efficiency. However, the centrifugal type kit (RIPP) will because it is less of a parasitic load on the engine. It works by increasing the thermal (how much energy is produced per explosion) and volumetric efficiency (how much of the cylinder fills up) of the engine.

A well engineered engine fills up 80-90% of the combustion chamber at BDC. If you force some air in there you're getting 10% more air and when the mixture is compressed and explodes it explodes with a greater thermal efficiency.

Once it's supercharged the engine does not need to be run as hard to achieve the same results so drivers tend to back off the throttle.

One more advantage of supercharging is running lower RPM's which isn't really related to fuel efficiency but it does reduce wear on cylinders and pistons and the inertial forces on the pistons and rod assemblies.

I know that superchargers put more air in. But they generally work at much higher RPMs than fuel efficiency so they result in more gas being used as well.

They result in more fuel being used because to keep the air fuel ratio correct you have to put in more fuel with more air. The RPM range is different for centrifugal blowers and Roots type blowers.

RIPP GEN II Stage II off-road.

Here is the kit off-road. It did well off-road but, like I've always said, it doesn't really need any more power off-road. The Roots blower guys always say that the RIPP kit doesn't provide power where the Jeep needs but, as I reaffirmed today, it doesn't need anymore power-off-road with the 4:1 t-case. The RIPP blower kicked in a few times but it always did fine before. Take a look.

I think your camera man needs a supercharger to help fill his normally aspirated lungs. Man, that guy was breathing heavy.

Your Jeep does not squeak like mine.

I still wish the powerband was at a lower rpm, which is why I have trouble justifying this purchase.

I'm guessing the cameraman was riding with the driver so he was sprinting up the hill to record the passes.

@OP, thanks for the vid. I know this is something on my wish list that's too far out to even see at this point, but I always like to day dream and collect info.
