  • 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.

      I think a complete 3rd gear pull is still better than an incomplete 4th gear pull. The difference in the results shouldn't be that big. You could compare the 3rd and 4th gear stock torque curves (plotted against RPM rather than speed) to confirm that there's not a significant difference.

      Give us the torque!!

      Here is the power chart the way pickles wants it....or as close as I can get it.

      The 2 superchargers are in 4th gear. The stock line is power in 3rd gear. I just laid the stock 3rd gear pull over the 4th gear pull and its pretty much the same line till the spot where the 4th gear pull hits the speed limiter.

      So this should be pretty close to accurate. BUT THESE TRUCKS ARE NOT ALL IN THE SAME GEAR.

      Thanks for appeasing me

      I like how the stock dyno pull started down near 1000 RPM. All the "I need loads of torque off-idle or else it's useless for me" people are going to complain that we can't see the torque gains in the 1000-2000 RPM range. Then there will be conspiracy theories about how you purposely avoided charting that area with the superchargers because of the lack of gains there.

      Guess you have to start over :-p. When you get your hands on the Prodigy turbo, can you try to start that dyno pull as low as possible?

      You realize, im not operating the truck on the dyno. Im standing 30 ft away. Then they email me the file. That stock dyno is at a different shop from the SC dynos also.

      I can ask them to start the line as early as possible I guess.

      Here's the torque chart.

      Same story as horsepower, Magnuson at the bottom, Ripp at the top.

      Both Kill the stock numbers by close to 100 lb/ft.

      Looks like the Magnuson might not have as big of an advantage over the RIPP at low rpms as people seem to assume based on the centrifugal vs roots-type generalizations. Although, it's impossible to know what the story is below 2000 rpm with certainty based on this chart. But as I've already shown thanks to the magic of math, 2000 rpm looks to be a low enough rpm to be useful for general off-roading: http://jeeplab.com/showthread.php?33...full=1#post802

      Great stuff Ross. And Pickles that is also right on math. The only thing I would add is that it is available power, It comes in as needed. If you don't have your foot in it you not going to get much if any increase in power. Which you might not want all the time. But if you need to suddenly scrabble up a loose hill then it is all right there. I assumed that the Maggie would have the edge in low speed and feel. I am surprised at just how close they are at low speed. The Maggie has the smoother curve of the two at low speed, which should be fuel and spark curve management. I love to crawl but I also love blasting across the lake beds. This is just some great stuff. Having had some experience with building turbo motors I am really looking forward to the third installment. Done right it should beat both of them across the board.

      They really turn out to be close to even. What you gain with RIPP high, you gain with MAG low. Hard to pick a winner.

      There is one loser... the hemi. I dont think the hemi's powerband would touch either of these.

      We should work out a dollars per horsepower ratio and see who comes out on top.....Dollars per lb/ft torque?

      Any more impressions of the magnuson unit as a daily driver?

      Sure, its better now than before. We got a new tune recently, and the only problem that seems to remain in a "surging" at crusing speed. it feels like the driver is touching the gas and letting go, over and over, but he's not.

      Im assuming it should be ironed out soon. but other than that, its a beast.

      And here are 2 sound bytes with my recent additions.



      An intake is a must for the magnuson. Before the intake, I hardly even heard it. The untrained ear would not have known there was a beast under my hood. Well, they know now!

      Hi All. I'm new to JeepLab but have been following along for a while now. I just finished installing the Magnuson S/C on my 2013 JKU. I'm working out the "kinks" now and I'm wondering how often you get updated tune files from Magnuson? My original tune file was missing ETC tables (thank Diablosport for noticing!). Mag sent me a new tune file and all seems OK. I notice some things like slight drop-out of throttle response at certain accelerator positions, a really "tall" fourth gear during highway on-ramp acceleration. It would be great to get any updates to tune files.

      Thanks,

      BTW - the Magnuson supercharger is has been a pleasure on my daily driver. I added an AFE cold air intake.

      do you experience the surging trottle at crusing highway speed?

      I do experience some irregularity. It's not terrible. I too would hope it will get worked out in future tunes or perhaps through some tweaking to the bypass mechanism. I can't tell why it's happening. I don't feel like the throttle is surging as much as I feel like unwanted boost may be kicking in or current boost may be cutting out.
