Hey everyone this is Eric at EHS Racing I wanted to show the airbox system for the razor we are working on. Its a total replacement aluminum upper box that still utilizes the OEM airbox. The OEM box is relocated which allows for a much more direct intake. Its still in the protoype stage but we should have it ready soon. Here are some pictures

That looks real good. Are you going to post measurements and instructions for us to make our own copy? You posted in the Projects & How-To section...

my only concern is why are you dummping the clutch ex back into the fresh air? its dirty and hot think id keep it going out like stock but now the rest looks great very clean

Could it be the air box has a division? If you open the attachment I circled what appears to me an opening in the box.

wow obie won you have better eyes than me.....i stand corrected now i like it even more than i did

If it indeed has a section for exhausting the clutch case air it's a unit I'd love to have.
I'm a sucker for nicely welded aluminum.
They seem to be into customer service as well.

Hey guys you are correct there is a divider that seperates the intakes from the exhaust. Right now the plan is to fill that divided section with the really awsome foam the same stuff we use for snorkels with our airbox covers. We had just finished that protoype a couple days before the holidays and only played with it for little while. Once we get back were gonna do some more testing then send out some units for customers to test.

We started the build including the guys at the prc forum there will be 5 people getting them at a reduced rate for helping us out making sure everything goes smoothly once we release them. I wouldnt ming doing the same with a couple here, as a thanks for letting us post here.

Some of the other key things with this setup are
The pre-filter is replaceable and its easy, bed removel isnt necessary once installed.

The airbox is rotated which creates a much more direct air route we use 2.5" od 6061 aluminum tubing for all connections. (hooking to the flex tube)

The hinge pin on the airbox and lid is removed and replaced with a spring clip. This makes a much tighter seal between the box and lid.

There is a custom aluminum intake adapter that connects the airbox to top box tubing. This seals much better than the stock tube.




Guy if you want to build one yourself you can call me I will give you some pointers but I warn you this has been a project. There defiinetly wasnt much room to work with.

I'd certainly be up to testing a unit at a discounted price.
If you follow my link, you'll see I like to dabble with aftermarket goodies and the electrical work I do myself.

It seems my signature with my link disappeared, here it is.

LOL Now it's back again but missing in my last post...bizzare.

Any new word on when this is gonna be done? I would like to have one for my rzr project!

I guess he left us for the "other" site.

Hey Guys i havent left the site, just the country for a week and a half im just getting back now. The razor box is pretty much done i have one getting tested by one of the prc guys now and will have 5 more going out early next week for testing. I will still hook a couple people up from here at the discounted rate for testing help. I will get back here either this weekend or the first part of next week.

Retail is going to be $425

EHSRACING - I would consider such a upgrade, but I really want a prefilter on the front. - do you have a option in mind for that?

hey where do we get that flex tube !
