    Pentastar + RIPP SuperCharger = SUPERSTAR?

    This is one of my favorite threads. Worked on it for a year. Started it in March of 2013

    Yep Its Done.

    Only 2 others in existance. Both auto. Ripp's and Rockstar's.

    The only 6-Spd RIPP SuperCharged Pentastar JK in the world is in my garage.

    I want to thank Ross and the guys from RIPP for all the work. I hung out with them for a few hours, they are all very cool. Same vibe i got at Rock Krawler with Justin and the boys up in NY state. Knowledgable jeep guys, who dont mind explaining the stuff that I didn't understand going in. Im not a mechanic, so sometimes my questions might sound silly, but these guys were happy to explain in detail, not bothered by my entry level understanding of superchargers.

    Here are the stats on Black Betty.

    12 JKUR
    315 Duratracs
    2.5 X-Factor Rock Krawler Lift
    6 Spd
    4.10 Gears.
    No Exhaust Mods at this time.

    Drove it for the first time today. It is very fast. The boys at ripp installed it, so im going to get more involved explaining the installation later. Suffices to say, the install was done in one day, then the dyno passes began. I'll post the before and after dyno numbers as soon as I dig up the pictures.

    Here is the short version so far. Ross from RIPP is pulling my truck off the dyno for a test drive, motions to me to get in. I'm freaking out with delight, as I had tried to stay out of his way for the last hour while he was dialing it in on the dyno. I jump into the passenger seat, ready to fire 1000 questions.

    The first question that comes out regarding the prototype supercharger set up. "So do I have to be careful with this thing?" I asked. Ross looks at me with a smirk, and then turns down a deserted alley, "watch this" then floors it. I can hear the WHHIIIIIIIIRRRRRRRRRRRR of the SuperCharger spinning. I was knocked back into my seat. He chirped the tires, with a hard shift into second, then to my amazement, CHIRPED THEM AGAIN going into 3rd!

    He was showing me that the "Prototype" that I had was not delicate or fragile. He explained that the dyno runs he had been doing for the last 2 days were harder on the system than anything I was going to do to it on the road.

    I drove it home on the NJ turnpike where I could open it up, but didnt get too aggressive with it. Ill give you guys my thoughts after I drive it cold tomorrow.

    Overall im impressed so far. but ive only driven it a short distance and really haven't gotten on it.....Yet.

    Heres a vid from RIPP with their 12 JKUR on the dyno. You can see Black Betty peeking in the window in the background.

    Ok, Here is a pic of the screen, but the "Tune" isnt done. What I mean by that is that I have numbers, but they are conservative prototype numbers.

    This is not the finished product you'd get from Ripp, but i couldnt keep my mouth shut after driving it. Had to share it with the family!

    This is all going on with EJS approching, so we were under serious time constraints. I got the truck to RIPP last Monday evening, so they had less than 8 days to install and alpha test the system in the Manual Trans Pentastar, before I had to leave for moab.

    So Ross(RIPP) gets his hands on the truck at 5, throws it on the dyno because im pestering him about how i want to show the before and after, etc. He did a "Running Pass" and we got -

    BEFORE
    215 HP
    190 TQ

    Yesterday, Before he took me on that test drive after install and a ton of dyno passes -

    AFTER - BETA TESTING NUMBERS 1.0 BETA NOT FINAL TUNE
    312HP consistantly
    270 to 280 TQ

    Now, let me remind you, this is halfway through the tune, These are conservative numbers. I have to bring it back on monday so he can finish dialing it in. I insisted on taking it for the weekend because we have a bumper to install, and im only half done with those lights you see.

    RIPP hopes for more power than this when we're done.

    Here are my feelings about it, not official word from RIPP-

    Im not sure if my perception is unique or not, or if the 3.8 is different from the 3.6 in this respect, but I feel like they talk about superchargers as being bolt on and easy to go back to stock. What that means is that you can install this system easily. And for the amount of power vs time to install its VERY EASY. We took longer to install the lift. But the going back to stock isnt so clear. You can change the belt and the truck will drive like stock. Thats true and easy and quick.

    But thinking your going to just unbolt the supercharger to bring your truck to the dealer for a problem wouldn't be so easy. This thing is really shoehorned in, and there are places where you need to trim a little to fit the pipes through to the intercooler and the hoses in and out of the supercharger are modded. Also the coolant bottle is replaced.

    So if you were to take it out, there would still be evidence that it was there if a mechanic smelled a rat and investigated the engine bay.

    At the same time, I researched the hell out of the 3.8 Gen II supercharger kit for complaints and only found one guy with AUTO transmission problems out of over 2200 kits on the road. Ross(RIPP) got his start over a decade ago, when he was working on a mod for a client and installed an after market supercharger (obviously not a RIPP) and wasn't happy with the quality of the product. He is a fanatic about driveability and durability over power.

    My truck could make 360 horsepower with this same system calibrated differently, but would drive like crap. The plan is to use the supercharger to mimic a larger displacement engine, not click on like a turbo. Thats why RIPP and diablo have to do 800(kidding, but not really) dyno passes to make it the way they want it.

    This is a whole new ball game with new engine, but I couldn't resist the power. Driving it now, I wouldn't give it back and i don't think I'd be able to live without one in the future. Also remember, Im a psychopath about my truck. I wrapped every inch of it in xpel ultimate healing wrap because I never wanted to see a swirlmark in it. I dont accept "its a jeep", F THAT. I expect it to be perfect. Not a scratch not a blemish anywhere, and I wheel hard. I wouldn't have handed my baby over if i hadnt done the reasearch and trusted the people I gave it to. ESPECIALLY FOR BETA TESTING.

    That being said, I have no idea about warranty concerns with it. I have the extended warranty on my truck, and unless its clearly a supercharger induced problem, which im not expecting even with an untested prototype, Id bring it to the dealer as is.

    Still concerned about running this on my 13 Auto. The trans codes are so severely restricted that I am afraid to mess with it.

    I'm pretty sure you'll be fine with a 13, but I'll look into it.

    Ok, word from the source is that the 2013 auto tune is polished. They do not expect any hiccups.

    My dad's 13 JKU sport with auto trans has had a RIPP for several months and thousands of miles now. It has required several (2 hour each way) trips to get bugs straightened out. First tune was no good, nobody contacted us about the new one when it came available, we had to call and complain then they said " oh we have a new tune out that's bug- free". Also with the auto you have to remember there is a " lift to shift" while at full throttle where you have to completely remove your foot from the throttle for a second at the top of each gear or the trans won't shift for several seconds. It's not bouncing of the redline it just kills all power and let's the SC spool completely down. This was especially troublesome for my dad when attempting to pass on a 2 lane 55 mph road. We weren't advised of lift to shift method until the 4 the month of ownership. I'm glad that BB's experience has been flawless, but our experience has been anything but, with calls and emails never returned, tunes taking days to get returned( which means you can't even start you jeep), numerous extra expenses ( not too mention all the wasted gas and time), the last time it was in the shop 2.5 weeks. One of the most frustrating things was we traveled so far because that was the closest RIPP authorized dealer to our town, then having to listen to the blame game between ripp and their installer. I can only speak for my father and myself, but I would never buy from them again.
