  • RIPP vs. Magnuson...SuperCharger Shootout!

    You knew it was coming. Its finally here. We are going to turn these to SuperCharger heavy weights loose against one another in a battery of tests. Lets get to know the competitors.



    Reigning Champ - Black Betty. She's and internet celebrity, been on the cutting edge of prototype gear for the last 2 years. She'll be representing RIPP SuperChargers in this all out throw down. She is a Rubicon Unlimited with 4.10 gearing and for the purposes of these tests, she will shed her 37'' KM2s in favor of BFG Kms 255/75r17. (stock Rubi tires)



    The Challenger - Sweet Pea / Pea Soup'd. Yes she's got two names, one from us, and the other from one of our readers. She's essentially brand new. 2013 JKUR all stock everything....Except her Magnuson SuperCharger.



    Whats the difference? Two routes to the same end. MORE POWER. its widely known that there is really no way to add punch to your JEEP JK without taking drastic measures. We have done the dyno testing on intakes and exhausts. The sound changes, but not much else. If you really want to unleash the beast that is your pentastar JK motor, we are paving the road for you.

      here's an idea

      post the size, item number and brand belt you use. I'll get a different brand, and we can compare notes.

      forgive me for hi-jacking, are there different brands of belts?

      Auto with no shifting problems.

      Not sure how you can determine that there are no auto shifting problems from this information. The video demonstrates wide open throttle shifts for 0-60. The transmission doesn't even shift through all of the gears in the video. From my perspective owning a supercharged jeep, I don't drive wide open throttle when I'm driving my jeep. My Magnuson will do what is in that video. My shift issues are daily driving, not racing my jeep.

      Your second post is about transmission coolers, it doesn't mention anything about shifting. I know I don't own a RIPP, but I've read about RIPP owners complaining about shift issues. I'm sure if RIPP had this fixed, they would be screaming from the roof tops on how they have it resolved, in an effort to sell more of their superchargers over their competitors.

      X2. this auto shift issue is a big problem. Once someone fixes it, they should offer a guarantee. That will sell a LOT of power mods.

      I thought that the Ripp complaints were about full throttle shifting and having to lift to shift. He obviously didn't have to do that as he did hit third. I guess that in the second one my thought was that they are towing and only have complaints about trans fluid temps not shift qualitys. I would think that they would mention a degradation or shifting problem as a possible suspect of the higher heats. Just something to add to the mix of info.

      Just reread your post on your trans problem.. I could not live with that overdrive problem either. Still nothing from them I guess otherwise you would have posted it. Sorry your having so much grief with your system.

      Thanks. It is frustrating for sure. I got a new tune last week or the week prior from Magnuson. The days are running together, so I don't remember which week it was.

      The engine seems to be smoothed out more than the previous tune, but the transmission overdrive problem still exists. I think the transmission is learning my driving habits with the supercharger and has calmed down slightly with normal shifts, but it still likes to hold the gears up into the 4-4.5k range if I'm a little heavy on the throttle.

      I don't know if it will help, but I've contacted a tuner in the local area. He is looking at my factory tune and the Magnuson tune that I have. I may be able to get on the dyno and get a custom tune later next week depending on his schedule. It is going to cost me $450, but I'm willing to take the chance. Even if my transmission shifts don't change after the custom tune, at least the tune will be for my heavy ass jeep running 40" tires, steel skid plates/bumpers, and heavy aftermarket full width axles. I might get lucky and get a little extra power/torque out of it and it might be enough to cause the transmission to stay in overdrive. I'll also know how much power my jeep produces with the supercharger on it instead of estimating based upon what others have seen.

      Ive had a custom tune done on my jk with the ripp kit. A company can only make tunes based on whats on the dyno. When my tuner tuned my jk ripps tune made 250 whp after 5 dyno pulls i put down 344 while getting air fuels and timing dialed into my trucks accesories like 35s stock gears 6 speed elevation

      **** MODERATED ****

      Hey everyone, if you've been following the forum, you'd know member FerrariFast totalled his rig earlier this year. He posted his new rig here. The build is extensive, and would have completely derailed the supercharger shootout thread so I moved it to its own thread.

      carry on.

      I called Ripp yesterday and they are still in testing with California for an EO# but they are going ahead with it. I do believe I am going to do some sort of power adder. But I live here in CA and it has to pass first before I plunk down the bucks. this whole tune thing with our autos just has me wondering if a engine swap is a better way to fly. Yeah much much more expensive. 23k but you end up with 335 hp and torque with a 6 speed auto. Heck I like my little V6 I just hate the trans ecu.

      Gunner's next jeep is a STICK. LOL

      Did ripp say anything about the shift thing?

      Nope just that it was being adjusted as ca asked for some changes. It's gonna be a next year thing. If I thought it would work I would put a stick in it and be done. Then I could do my atlas 4 also. But no it won't work with the auto either.

      Has anybody seen or felt there truck running more boost in this weather? My boost gauge hit 9 psi today and usually only hits 8. I know that when the air is colder is more dense but i dont want to risk engine damage with 9 psi

      Pretty sure you are fine.

      Every engine loves cold air. People run the pentastar up to 12 psi.

      The Magnuson unit is actually called a Hybrid Roots lobe or Twin Vortices Series design. It is a combination between the traditional Roots system (designed in the 1860's) and the more modern Lysholm Helical Screw System (designed in the late 19th early 20th centuries)-- both are positive displacement designs and the real difference is that Roots units actually doesn't increase the pressure inside the unit. That has to be done with in the cylinder head. Where as a twin rotary screw unit does compress the air within it. Also the Twin Rotary Screw systems show less parasitic drag because they are more efficient and usually require less power to operate when compared to a roots unit.

      The Ripp is a simple Centrifugal System-- basically they became popular in the 1930's when supercharging aircraft engines. They basically are just turbo-superchargers that replace the rear impeller with a drive shaft and gearing unit that directly drives from the engine. These are probably the best unit to use for two reasons: One they require little horsepower to really operate because of their small size and high speed operation. They are also are the most flexible-- you can get them with a hi-low range or even a combination of hi-low and 2-stage units if you are so inclined to do so. Those are features that you cannot get on roots or twin screw unit.

      However, if you're going to spend the money-- I say use sequential turbo-superchargers... With a properly mated system you can eliminate turbo lag and produce massive horsepower with very little back pressure on the engine. It is about as free as one can get.

      But no matter the system-- water methanol injection would really improve the performance overall with any fuel source.
