Ripp supercharger for 3.6 in the works!

Not sure if this has already been mentioned but found a 2012 jk with a ripp supercharger on YouTube. Can't wait to see the numbers!

Doubtful, otherwise we would see the performance chips come out of the woodwork. It seems no one can crack the ECU of these things.....yet.

Why though. I thought the p-star was really really fast?

The hemi killer guester was quite comical I think. Can't wait to see the numbers. Looks like the 3.8s are getting around 100 HP increase I would expect similar numbers with the 3.6. A 400hp Jeep would be fun!

Just got off the phone with ripp. They said the kit should be released next month. He said he couldn't give out exact numbers yet but its over 100 rwhp@6psi and he said that the 3.6 is a very stout motor and shouldn't have any problems running 8psi or more. He was very impressed with the motor so far and was surprised at how well it breathed making power easy to come by.

I wish someone would slap a turbo on the Pentastar. 450hp with 30mpg would make this guy very happy! It's only a matter of time though. Mine is still under warranty (2012) but by the time I decide to go FI, someone will have a kit guaranteed.

I am saving up for a Ripp SC on my 2011. As far as the PCM, the Ripp system on the 2011 (and 2012 when released) will be a piggy back system. Not a computer re-flash with the programming such as found in the 2007-2010 kits. They are still unable to break the encrypted rolling codes that Chrystler decided to throw at the 2011+.

The piggy back system does not change the stock fuel injectors and adjust the PWM (Pulse Width Modulation) like in the 2007-2010 kits, it rather add two additional injectors upstream of the throttle body and uses the piggy back system to modify the signal for timing and fuel trim along with adding additional fuel via the two extra injectors when the system goes from vacuum to boost.

I have also talked to two people now that have the Ripp SC kit on 2011's and they have both told me that the 3k RPM surge/flatspot that seems to be somewhat characteristic in the 2007-2010 kits is gone with the piggy back system.

I am really wanting to get one of these as soon as I can afford it.

Mike.

Interesting. This is usually a very inefficient setup with reliability issues (adding injectors.) Not an ideal solution IMHO, and I know a thing or two about FI, I've built 10 cars of my own.

Thats cool!

They have said the Pentastar was built for forced induction. I think its only a matter of time before it trickles down the line.

Alot of companies are going to turbos for better mpg,, and power, less weight.

Any Turbo in the Jeep would be way cool,,,, Simple chip on these things and you see big gains for little $$.

Now Lets see the SRT-8 Wrangler with a blower, Air Bags, chopped top, ZF Tranny.


SOLD,,,,,,,,,,,,,lol I have only had my '12 a month too.

I'd still rather have a CRD with a tune and turbo back exhaust, more bang for the buck But this whole supercharger thing is pretty cool too

I would bet you are going to see many more vehicles coming from the factory with forced induction, be it as turbos or superchargers. This is a very easy way to get the volumetric efficiency up on any engine and with the new CARB laws the manufacturers are going to have to use any and all the tricks they can.

As far as a turbo on a Jeep, I know they work the technology is what it is no matter what engine, my problem is with the heat that will have to be dealt with on a turbo in an already very warm Jeep engine bay. Especially in a slow moving off-road high ambient temperature environment.

A turbo on a sports car moving at 70+ MPH has a lot easier time of expelling the heat out of the engine bay that a Jeep crawling around on the rocks in 90+ degrees and no air movement.

Just my opinion.

Mike.

Could not solve this by removing the current fan which will give a small amount more horse power gain and put electric fans to force that hot air out. Not very expensive to be done.

Due to how each work a supercharger is a far better option for a jeep. Don't get me wrong, I LOVE my big turbo on my Subaru but they don't make power instantly or at lower rpm ranges, however a super charger is just the opposite, quicker throttle response, more power in lower rpm ranges.. Now let's talk about a "dual induction" setup.. Supercharger feeding a turbo!!!

Why would you say that? There is no situation (other than top fuel dragsters) where a supercharger is more efficient than a turbo. The turbo in your subaru (STI or WRX?) is slightly larger, so your full spool arrives somewhere in the 3000-4000 rpm range. I have seen autocross cars that develop FULL SPOOL at IDLE!!!! In a Jeep, you would want low end, and not care about top end, so you would have a smaller turbo. This means, that if you put a Garrett GTX35, your Pentastar wrangler will be putting down a solid 800hp, but you won't have it until 6000rpms, useless to a Jeeper....this is why those dyno queen (1000hp+) Supras are dog slow unless they are drag racing. Now, fit a Wrangler with a GTX28, and you will put down a nice, healthy 400-450, but it will be available INSTANTLY, thus, being of MUCH use to Jeepers. Hell, a fast spooling turbo will eliminate the need for 4LO, since there will be GOBS of tq available at a VERY low rpm.

Remember, a supercharger setup, while great, "reliable," etc, is ALWAYS parasitic, and thus, is NEVER as efficient as a turbo....not to mention, the power curves. Since the blower feeds on the motor, it's power is proportional to the motor's power, unlike a turbo.

P.S. You should take a ride in my turbo S2000 to see what "throttle response" means.

P.P.S. A friend of mine in Long Island has exactly that, he has an STI with a supercharger spooling the turbo. As you can imagine, the car is cartoon comedy fast.

I say this because my wrx is not stock by any means, not even the horns in the engine are stock.. I didn't say anything about efficiency, no turbo, unless it's so small that it will choke out at mid rpm ranges can provide the low end that a supercharger will. I've done serious research on this topic in my Subaru build. A mid sized turbo like a GT30 or GT35R spooled by a supercharger is the best of both.. Yeah sure a supercharger creates drag due to it being spooled by the crank but it creates far more thus being worth the install.

In general I would agree with you, however the JK's already have electric fans and there is still too much heat under the hood in my opinion.

The centrifugal superchargers that are available for the JKs as well as many other applications are not a positive displacement or "roots" style supercharger that you may be thinking of.

The centrifugal supercharger operates much like a turbo as far as the airflow much "spool up" for lack of a better term. The power of a Ripp SC (which the supercharger is actually a Vortex brand) is mid to upper RPM range much like a turbo charger. Ripp will even tell you that if you talk to them. It still is noticeable at low RPMs but the boost comes on gradually as RPMs build.

As far as throttle response my little 1.3 litre Mazda B engine in my sandrail that is turbo charged and wastegated has amazing throttle response and only builds to about 12 psi of boost. The difference is it being an all tube chassis and the engine more out in the open to expel the heat and the fact that it is not crawling at slow speeds definately help with the heat factor.

Mike.

I understand what your saying, how ever I am talking about a roots, in my argument about a dual system "bolt on kits" are not relative.. There is a specific root bLower that I'm thinking about after researching a dual induction setup for my WRX. As for the centrifugal blower that are belt driven same apply as exhaust driven turbos, size, both housing, turbine, and pulley determine spool.

I'd like to see a top mount, twin screw type blower. Like a Whipple or Kenny Bell. They are better for low end boost then a centrifugal supercharger or turbo, no? I would think it would be a better setup for crawling at least. Either way, I can't wait to see the numbers!

Very interesting....

I'm not much into these type of mods (I prefer the simply mods on my motorcycle that take my Bonneville from 50hp to....52hp)....but.....that seems pretty damn powerful.

A tire shredding, sports car eating, 4 door Sahara? The tranny can handle the power...but what about the "tick"?
