Dave, Thanks for the imput, I have only had the 28's on one time since I bought them from you and it was pretty tame stuff. Did you ever get your long trave setup??? Hope to see you again this weekend in Moab.

To fare and to much Money but thanks .

We didn't test that one, but based on the 10 we did test, I'd say your best bet for maximum power would the power commander, so you can remove fuel from the stock curve. If you can't get to a dyno to test it, though, I'd run the stock curve. Adding more fuel will reduce power with your pipe, most likely. But, I can let you know what all I have tomorrow, if you're really stuck on having one.

Adding a pipe does not richin the mixture, It leans it, You will need to add fuel when you put a pipe on :!: .

That's the theory, but the stock AFR's of the RZR are too rich to begin with, so after adding the pipe, we still pulled fuel out of the curves to maximize power.

I found the same with a Suzuki EFI with a new pipe. Initial setup on the Dyno was fine, added the pipe and the ratio was too rich. Talked to a guy at BUB that was running the Dyno and he said it's pretty common

Leave now! And, it's only Money Really, all these RZR guys breaking down in Moab will need all the help and expertise they can find

I am thinking I want to run spacers on this trip. $105/pair... Ouch! Anyone have some Rhino wheel spacers they want to sell?

Spacers? What do you need spacers for????

What is really weired is that all ATVs and all UTVs must meet federal emissions standards like lawn equipment before they can be sold now so if they are to rich they could not pass :?: , That is really weired :?: , That would mean that the stock system would be less restrictive then the aftermarket system, When you move more air through the engine you need to compensate with more fuel, That means the engine would have leaned out to do that, In every race car i have dealt with when we take the exhaust off the header collectors we had to go up in jetting to compensate, That is the reason when you go up in altitude the older carburated cars start to run way to rich because of the lack of air, as for the Polaris and your Suzuki It may be because the the ECU and the T-map sensor gets confused and starts adding to much fuel to the fuel map because of the aftermarket system, That would be the only answer to this question, After all They do not have an O2 sensor seeing what is coming out of the engine to compensate, The ecu's aren't smart enough :idea:, Any how this thread was not meant for auto shop 101 and I will stop babbling on this .

More bravery of course

RANGERDALEXP · 2008-11-10 20:30:26

Hey guys good luck in MOAB and For Badley you will need thoughs spacers to keep up with the Polarises "Just Kidding", I know were there is a set but i do not think the owner will be to happy with his Rhino is up on blocks , Have a good and safe trip guys and girls :!: .

I don't disagree with you, but we just tested 10 different pipes with fuel controllers and had to decrease fuel on every single one at certain points in the curve and only on the better pipes had to add some fuel to compensate for the additional flow. We'll have all the PC curves available soon on our website.

Sounds really good, It is something else that they would and could get away with running an engine that rich and the EPA would O.K. it, My 2001 XR650R has smog on it and Honda had to sell the go fast kit on the side to put it back to what it should be, It is A New intake and a high flow exhaust tip and a bigger jet to rich en it along with removable panels at the filter box, it still has the smog equipment on it that is required, My 2005 Ranger XP ran so lean that the plugs were showing white, The SP ecu took care of that problem and the 2006 and the 2007 we had to add fuel with the fuel controller with the stock exhaust and even more with the exhaust Modifications.
