More Power from your Torque Converter? THE JUGGERNAUT! Review and Comparison! | Mini ATV Part 4

In our last video, we took the Mini ATV out for a spin and decided it needed some more power. Gopowersports sent us their latest performance product, The Juggernaut! The install was extremely quick and easy, and the results were immediately apparent. We noticed improved take-off and top speed while riding. The Juggernaut lets the engine reach higher revs than a traditional torque converter and reduces belt slippage after long periods of riding. Definitely a must-have for any built engine!

From 45 to 48 top speed without touching the engine is actually a noticeable difference. From 5.60 to 5.10 seconds a big improvement especially on such a short run. Great video guys! Keep up the great work. Aloha a hui hou.

[@kartnerds]

That little quad is moving! I was hoping someone would do a comparison like this. Great video. Really dig the quads aggressive new look.

[@eyeballengineering7007]

Hey. I'm running the Juggernaut too. I found it revved out at lower speeds better when the secondary driven spring is in the 3rd tension hole. This is awesome on a highly built engine IMO. I hit 6000 while accelerating and not from belt slippage.

I'm excited to pick one of these up for my MB200 soon. It's mildly built right now, but I'm planning to do more. I do wonder if the difference is noticeable between the Juggernaut and just swaping springs and weights in a standard series 30 TC? I have the stock weights in mine right now, but I did swap in the white springs which increased engagement from ~2200rpm to 2800rpm. Cost of aluminum weights and springs is not far off from a Juggernaut, though. Side note, you guys should invest in a Dragy. GPS-based device that can track speed/time over distance, etc. Can get more accurate times for whatever distances you want to set.

[@eyeballengineering7007]

Bare minimum you want a cam with one of these.

[@tycoonbob]

[@alleyoop4465]

Stall speed will have very little affect on top speed. Launch and ET definitely yes because the engine is in it's power band before its actually motion but not top speed.

Weld a grate on for your feet.

[@jeep2003]

They definately have a better design than the comet much smoother engagement im sure. Its a really bad idea to run without a cover on the 30 series if the bolt breaks or comes loose the weights fly out like a grenade its super dangerous happend to me a few times.

I bought one for a stage 2 predator build, to try to get more speed for the higher rpm, it was worse than the standard 30 series. I lost speed and power.

[@sanesaint8725]

I guess you could all ways change front sprocket for more top speed, bigger back less top speed but more torque

[@westie4ageturbo.749]

Seems like the rear sprocket is small so the impact is reduced. If your gearing was lower the impact would be greater.

Honestly for the price you have to pay to build a 212 is kinda retarted but you do get high end parts that will lasy longer and probably for cheaper you can buy a lifan 200cc shifter engine for under $600 and go like 70mph plus on a bike and it will be able tondo wheeles with a 5 speed trans.

D....I doubt it would do either on a stock predator without the Governor removed but doubt it could do any harm if your hearts set on one but your rev/powerband would be pretty narrow waiting for the modified clutch to engage then the rev limiter would kick in, save your $ & put on a suitable bike slider carb: go to Amazon..Cheers Trev NZ

[@Deucealive75]

I would bet these aren't worth getting if you are running a near stock engine. With a mainly stock engine you would be better off modifying the stock driver, a gearing change, or both.

[@Deucealive75]

@Knight Recon Shouldn't be noisy. Not sure why it would rattle.

[@derekfox6543]

Both of my stock drivers rattle like crazy at idle on my mb200s, but the both work just fine.

[@Deucealive75]

@Elijah Scott LeFever Yeah not sure why. You would think that the only time it could make noise would be when the "clutch" is not fully engaged. If it is noisy, at least there is no stress on the system making it less of a concern. If noisy while engaged I would be pulling it apart to investigate. Oh this is that Juggernaut video. I'll never get one. I get Juggernaut performance from gearing, at least until the belt shifts. haha. And the OD function can be beneficial if the bike is ever put on the road.

[@Deucealive75]

@Elijah Scott LeFever Please do a video on that if you are successful. I thought about doing it but just can't find a correct size to go over the hub. Something plastic like PVC would work great because the PVC would wear and not the hub. Even if the PVC was tight on the hub the belt would just slide on it while idling. But if you can find a bearing that fits nice that would be great. If I had a lathe I would try to make one out of an oversized bronze bushing.

[@colefrisbee9978]

The best in my opinion is just a straight bully clutch

[@chrisharding2813]

I switched from the comet 30 series to the juggernaut and lost almost 10mph lol... I assume the Juggernaut doesnt have any form over overdrive or maybe i need more than 4500-5000rpm to fully engage it idk.... Overall I was kind of pissed off with my purchase, might use it on another project but my goal was to get to 50mph. I was previously at 40-41mph with a cheap chinese comet clutch. Dropped down to 32mph with the juggernaut =/. Only thing i noticed is it revs easier and has a stall on it that around 2300rpm on my tach it begins to engage. I messed around with my gear ratio and it doesnt want to go past 32 now.

[@deathtrapperformanceminibi260]

From my own experience the juggernaut didn't really shine until I had done some serious mods to my engine milled/ported head flat top piston big cam w/ratio rockers me personally if you have a stage 1,2,3 I wouldn't waste the money on the juggernaut as you won't be making enough power to fully utilise it

[@chrisharding2813]

Doesnt sound like your torque converter at that point.. seems more like the engine is just better than stage 1-3

[@chrisharding2813]

@Knight Recon nah haven't had the time. Im almost 100% positive it doesnt have am overdrive so its just not meant for top speed

[@chrisharding2813]

@Knight Recon try a 40 series comet clutch. Thats my next purchase. The overdrive in the comets gives you another 10mph. I think the juggernauts are cool for drive ability. But not meant for top speed. Id almost prefer a clutch over a juggernaut.

[@Deucealive75]

@Knight Recon What bike do you have and what is the sprocket count? The Juggernaut is for big power high RPM engines. A lot of guys like these because the gearing change with the belt shift is not as dramatic as the stock driver. The Juggernaut does not even get to a 1:1 ratio. If you want to run it and do not want to build your engine you will need to gear for it.

that poor ratchet 😂

[@SuperBigdanno]

That belt is way too long, you are starting off in second or third gear. I see this all the time on these systems. Also a bit wider belt would help as well. The reason is the clutch is so hot is because of slippage, get a proper belt on that thing and you will be amazed at the difference.

[@SuperBigdanno]

Just a note, 160hp snowmobiles can do full pulls for a long distance and the clutches would just be warm not hot like you showed.

[@DarkLinkAD]

This is a scam... you can achive the exact same results by chaging your weight springs in the driver ($10) vs $100+ for this pos. Nice try 🤣

[@eyeballengineering7007]

Not even close. I have many Tav2's on built engines with aluminum weights and different springs. This is entirely different. I have a juggernaut on a 9000 rpm fully built, ported 212 and it's a world of difference to the tuned tav2 driver that was on it. They should have had the secondary clutch on the third hole. It accelerates even better by holding the gear even more. This is not for a stock engine IMO. It wouldn't upshift enough I don't think. This is best suited to an engine that hits at least 6500rpm under load

[@Deucealive75]

@@eyeballengineering7007 I agree. With a closer to stock engine there is not enough power available when the shift starts to delay the upshift. Even though you get a later upshift a near stock engine still can't overcome the gearing change at that RPM with the given load. And whatever engine you are using you would think the gearing is still important. There are a lot of bikes out there that are not even geared properly for the stock CVT let alone geared properly for this driver.
