Re: Air Box relocation

if you totally relocate it youll loose performance the farther your air has to travel thru pipeing the more itll hurt you . if your trying to solve the dust in the intake problem the link i posted completely fixes the problem

Re: Air Box relocation

ohiotodd...I don't think RZR owners realize the affect that a DIY snorkel or any modification to the OEM airbox has on performance. I see owners with 8-10 combined feet of extra pipe and is surely hurting performance and also the engine by trapping heat. I also don't think they realize that it takes a lot to pull the right amount of needed air into the engine through all that large diameter pipe.

I think the better idea if any is to build a new air box like EHS did with top vents, but first measure and match the total airspace of the OEM setup and duplicate it as much as possible with minor improvements for airflow.

Just imagine having a ShopVac with the short normal length hose...this provides the best suction power and performance...adding two more extension tubes would considerably cut the suction (CFM) probably by 4 times and you would also hear the difference in the speed of the motor.

I realize that everyone is wanting to keep dirt, dust and water out and not have limits on where they go with their machine, but they can't expect the same performance or more performance from the OEM setup.

I enjoy riding the river where I live, but just stay out of the water that would get to my butt level when riding. That's just my preference...For the guys that love the deep stuff and mud I think as straight a shot as can be achieved with minimal length is best.

if you use the set up i showed its only gonna suck water if your sucking water as its a sealed system for the motor and cvt and it pulls air at your neck level so if its drowning you will to and splashes wont matter as the outerware cover is water repelent

you are exactly right but ive givin up on telling people that cuz they dont want to hear it or cant understand how the snorkels or moving the airbox farther hurts perfomance so i dont really bother anymore and yes ehs has the problem solved the box is completely sealed off from underbed air and the cvt exhaust is moved up the cvt intake is filtered and it comes with a bracket that rotates the airfilter canister so the intake is shortened and straight plus moves the canister closer to the thottle body so the boot cant come of anymore and supplies more air to the motor than it can possiblely use the air is so much more volume and such less restriction that just putting it on alone and changeing nothing else raised my idle 500 rpm thats unrestricted air i was also able to turn my dobeck up a good bit as well im completely satisfied

Re: Air Box relocation

Yep...Spot On!

Restriction is not always a bad thing! It's Often an "Engineered Thing"..!(Grin)

I worked with a guy that has been in the snowmobile and ATV industry since it started and he had me build the best laid out airbox mod that I could figure out and guess what...As soon as he put it on the flow bench it failed horribly! It was Way off...I had matched the volume within 5 percent, but the velocities were shot. All it did was "Puddle" air. Once we made the enhancements it just wan't worth the work and it wasn't something cheap and easy.

The nicer looking one that I have seen is the Cyclone setup with the snorkel. I've used that exact setup before in another application and I know it works very well.

Re: Air Box relocation

If you use any solution that keeps the stock intake box between the seats you also accept that the engine air intake must compete with the CVT fan for the same air source. As the engine spins faster it needs more air--just as the CVT fan spins faster it must draw more air. Does the CVT fan win and starve the engine for air? I dunno for sure but it sure seems likely to me. Is it engineered to work best this way or is it a production compromise to save space or money? I'm betting the engineers lost this round to the bean counters.

The EHS box (AND snorkels) separate the 2 air consumers. Some snorkelers report they feel a small performance boost.

Yah, but you can't say the product is good. The IDEA is good. Most of the application is good. But like anything else, there are problem areas, and Polaris has done a TERRIBLE job of customer support, from the factory right down to the dealers (in many cases).
BUT. And it's a big but.
The commitment by the Owners and users to find ways around the factory and dealers, and then to take their hard won experience and share it with others via this forum, IS UNPARALLELED.
Without this forum, and the (mainly) wonderful guys and gals sharing their experiences, I would have dumped my RZR by now, just from sheer exasperation with the dealers and factory.
I don't generally post a lot, but I read EVERYTHING that is posted, and I thank everyone who wants to help us develop great rides, in spite of how useless Polaris is.
Thank God there are people prepared to put their dough on the line developing new components to help us work around the POS Polaris garbage.
And that's all I have to say about that.

Re: Air Box relocation

RZRARMY do u think that if you increase the filter size for increased air flow you off set the length of pipe for the snorkel?

Re: Air Box relocation

I would answer Yes to that question, but it would be hard to figure out to be exact. I do think you have enough room to get away with a small amount of restriction loss. Are you doing anything with the exhaust or fuel mapping? This is just a question I have because of what you are wanting to do with a more free flowing intake.

Re: Air Box relocation

Weel...good question. I just started a new thread about my intake fix that tells alot but i with the Box i installed I have noticed alot of extra power. raced a buddy on a stock RZR and smoked him. No doubt fixed my dirt problem. I think I am going with a Gibson exhaust and a dynojet power commander III USB. The controler was recommended by "Cordachine" because it was highly programable. Fuel controlers are not my area but it sounds like what i would want. Something to calculate my increase in air flow AND a new pipe, not just a pipe My only concern with a controler is what are the long term effects on my engine. I have no idea.
