Newspaper2 Who makes the Best Turbo Kit for the Polaris RZR??

Want to know who makes the best turbo kit for the Polaris RZR? That's easy, just look who everybody is copying! Here's a few things we were the first to do, most of which we've been doing since day one!


Turbo cradle assembly:

Look closely at some of the newer turbo kits on the market (You know we mean you K&T) and you'll find the exact same bracket supporting the turbo and muffler.

Why ours is better: Ours is stainless steel & laser cut, on top of that we have them all coated in industrial nickel coating to last the life of the RZR. Ours are not just simply polished to look good out of the box. we've been doing it the right way from the very beginning


Air/Water Intercooler:

We've actually been doing this for a long time but didn't release them to the public until the beginning of this year. Now everybody is making these kits, some of them are nearly identical to ours....

Why ours is better: Our intercooler assembly has a built-in pressure switch that automatically turns on the fan to blow air through the secondary radiator at any boost above 2psi. This minimizes the load on your RZR's electrical system. Ensuring the radiator is only being cooled when necessary. Also you may notice that our system has few angles or drastic bends in our system. Why? because our is designed for optimum throttle response, not just to fit under the bed.


Secondary Radiator & Hood Scoop:

This design clearly makes the most sense to get air to the secondary radiator which is why we've been doing it for almost a year now. Strangely there's other kits on the market doing the same thing...

Why ours is better: Our setup isn't simply a radiator sitting on top of a fan under the hood. First of all our hood scoop is directly attached to the secondary radiator, meaning all the air going through the scoop is channeled directly through the radiator. We don't just have some off the shelf hood with a scoop and hope the air ends up through the radiator, we did it right. We also use a fan on top of the radiator blowing air through, not below. Unless your fan below the radiator is sealed on all sides then you're pulling air from around the radiator instead of only through it, not very efficient, especially when your scoop isn't very efficient either. So if your water isn't getting cooled down properly then you intake charge isn't either, which means that fancy new intercooler setup you just bought is actually costing you horsepower.


Donaldson Filter

We've been doing the Donaldson filter for over a year now and it looks like the other guys are catching in and using it on their kits now too.

Why ours is better: Ours is above the bed pulling fresh air into the turbo. While it does intrude on bed space it doesn't get heat soaked by being under the engine bay, being should to shoulder with a hot intercooler and an even hotter turbo. If your initial air intake is hot then you're going to need a pretty efficient intercooler to cool everything down.


Wide-Band Oxygen Sensor:

It's hard to believe that the most critical tuning tool is something that only we included with our kits. now that the other guys realize it's importance a lot more kit manufacturers are including them with their turbo systems. Again this is something we've been doing since the very beginning guys, because we go the extra mile to do things right.

Why ours is better: We use AEM's wide-band oxygen sensor and digital output gauge because it's been trusted in the automotive industry for over ten years for it's accuracy, responsiveness, and reliability. We didn't just throw together a display and a sensor.

Custom Clutching:

Since the beginning we have been including a custom clutch kit with every one of our turbo kits. If you had a setup that required slightly different clutching we sent you the parts you needed free of charge. Anything to make sure your turbo system gets all the power to the ground. No it would seem that a lot of the other guys are including clutching with their turbo kits, most of which are adjustable. Which may seem great, however you are left to do the guess work and figure out your clutching on your own.

Why ours is better: we worked with the CVT professionals at EPI to get the perfect clutch put together for our Aercharger RZR. After weeks of testing we determined the optimum setup and it's been in every RZR kit to leave our shop at no extra charge. As stated above if you happen to have other clutching requirements give us a call and our clutching experts will get you squared away.


So in conclusion there inevitably will be more impostors out there but just remember who brought you all of the above first

Re: Who makes the Best Turbo Kit for the Polaris RZR??

first dosent mean best.. look at trucks.. first came ford... chevy is better.. :P

How much is your full kit?
have you tested against an mcx kit so your claims of being the best are true?
any dyno sheets from users with your kit not one supplied by your company?
any rzrs out there with your kit with over 2000 turboed miles, and if so how has it held together?(turbo and rzr driveline)
How is your setup going to hold up to mud and water? ( and i dont mean rain i mean maybe being submerged..this is NH..)
My own personal preferance is my didrty dog clutch kit with adjustable weights, so that is what i would use with turbo. are your guys going to be able to help with weight placement on the arms or am i on my own?


I only ask these because i am researching which turbo to buy. I have no dunes in NH and mostly woody trails so i dont need to go 80 mph all the time. b ut i want to anyways . Im looking for throtle response and serious grunt from lil to full throttle.

Make me a buyer.

Mike

Well that depends on who you ask!

$4,995 gets you the fastest spooling turbo on your RZR. And that I might add, is something no other company will be able to imitate. We don't charge you extra for clutching or a wide-band.

Of course, so have plenty of our customers. The best is when other turbo kit dealers take a ride in one of our RZRs (even our heavy RZR4) after having rode nothing but the competition's turbo RZRs and they say things like "wow, I had no idea there was this much difference" or "this is how a turbo RZR is supposed to drive" or "we'll be selling your kits from now on". Unfortunately a lot of those types comments never make it onto the forums which are dominated by other companies marketing presence. We don't have a dedicated marketing staff, we just have a dedicated engineering staff. That's why we have contracts with the military doing everything from cryogenics to UAVs.

You'd be hard pressed to find accurate, non-biased dyno sheets out there for the various RZR turbo kits. First of all no dyno will read exactly the same as the next and it will be a rare occasion to find two different brand turbo kits running the exact same boost, with the exact same modifications, on the exact same dyno. So unfortunately it's a he said, she said kind of situation with dyno charts. But there is one undeniable fact that even plenty of Polaris technicians out there can confirm and that is the fact that our turbo simply delivers a broader power band and will out-spool any other RZR turbo out there.

Quite a few, hopefully those guys will chime in on this thread. You won't see and worn down spark plug boots, or people having to modify their fuel rail to clear their silicone hoses just to make their turbo kit. Ours bolts right on, doesn't rub on any other parts, has the highest quality components, and you don't even have to tap into the engines oil for the turbo.

We have quite a few guys doing just that. The only thing I would recommend, as with any turbo kit, is to be sure not to kill the engine while it's under water so no mud or water can get backed-up into the turbo itself. As for whether or not our filter will stay clean well take a look at this guys RZR after doing the hair scramble races. Everything but the filter and intercooler is covered in mud:


He took first place by the way


Also if you are looking to go through some real deep stuff check out our Donaldson snorkel kit. You'd be hard pressed to get any water in there:

Absolutely, we'd be happy to help. We have a massive excel spreadsheet showing the results this weight and that spring. we've spent entirely too much time testing different clutch weight/spring/belt combinations. we've even custom ground our own weights for a few customers.

Sounds like no turbo-lag is right up your alley.

Re: Who makes the Best Turbo Kit for the Polaris RZR??

Mike --

I'll make my post short and offer my opinion on the Aerocharger System.

Keep this in mind as you ask HP questions ........ All Turbo kits produce enough HP to bend a stock crank.

As to engineering which is my field -- There kit is 2nd to none.
As far as craftsmanship of their System - Again .. No equal.

I put my money where my mouth is and have now 2 of their kits.

And I believe I'm the 1st one to have an Aerocharged '902. I felt that strongly on sticking with the Polaris motor and their Turbo System.

Like I said - They all make HP .. But -- For my money .. I'll stay with the Aerocharger Turbo System.

Re: Who makes the Best Turbo Kit for the Polaris RZR??

Is their anything else you need to do to the motor internals, or can I just install and go?

Re: Who makes the Best Turbo Kit for the Polaris RZR??

Coming from an mech. engineering backround myself, its the attention to details I notice about this kit paired with the educated support that draws my attention to this Aerocharger system almost daily on this site. Collin, would you happen to have more videos of this system in use? Not that I am doubting any of your claims or statements, just merely entertained by this product.

Check out Sparky's videos. He has clips of everything from hill climbs to building boost in neutral.

Thumbs up Re: Who makes the Best Turbo Kit for the Polaris RZR??

I have a good friend who has one of Collin systems installed on his S and I was honestly very impressed with the quality and fitment of the Aero kit compared to others available... Also he didn't have to tinker with anything, just turned the key and go; not to mention the damn thing was like a little rocket ship!!! Everything looked OEM, which in my opinion is a testament to the true engineering behind Collin's work...

Re: Who makes the Best Turbo Kit for the Polaris RZR??

Whats the word on the stock crankshafts holding up with the low psi setting (I believe 6.5psi)? The more I search, the more common-place damaged crankshafts seams. I plan on going the water cooler route for heat transfer efficiencies, running the dynatech included with the kit (I assume you will have this controller pre-set correct??), and of course running 91 octane fuel at 12.0-12.5 afr. I dont believe you can get any safer than this if one was to go boosted

Im running 11 psi on the stock crank. So far so good.

With the Aerocharger kit I am assuming? I plan on sticking with pump 91-93 so I believe I should be knock free at the 6.5. I wonder what the expected WHP increase is at the 6.5psi?
