I'll start by saying that I don't own a rzr yet but working deligentily at getting one. Two of my co-workers have rzr-s' and I have spent seat time in them quite a bit. When I buy it will be a 2010 s, either 2/4 seat, haven't decided which yet? The area I will ride locally is quite hilly and I noticed on both that they seem to need a little more power in the bottom/mid area to assist in transitioning from the bottom to top of these hills. Most of the common mods seen listed by vendors remind me of the mustang 5.0 parts retailers, everything advertised gives you 5+hp. I'm looking for input of hp mods that have actually worked for you. Not interested in a turbo or BB kit, have no need for turbo power(nowhere near any dunes) nor do I won't to tear into a new engine. Ideally looking for a solid upgrade of 10-12hp for 1500$ or less! Figure I will need to upgrade the clutch but hope to get by with a EPI trail kit or something similar. Figure I will definitely need the upgrades if I go 4 seat.

Not meaning for this to sound as if am slamming vendors or anything! Just dealt with alot of the aforementioned 5.0 mods for customers cars who had bought their own parts without consulting someone in the know! I'm new to this rzr game and have so far seen where people have been somewhat disappointed with bolt on mods they purchased. Would like to learn from other's mistakes! Just hunting for solid advice!

From reading posts on this same subject, I don't think you have many options. You might see a slight gain on a combination of improvements, but I don't think your going to get a mild seat of the pants feeling on hill climbs without going over your limit. Maybe Im wrong, mine is all stock, but I have driven some others with add-ons and they seem the same to me. Looking for someone with other ideas.....

I'm curious Brian,
Did you ever find any of those claims for a mod to make a quick 5+ hp in the Mustang ever ring true? :)

I was going to spend money on mods,but after i saw the price of the mods and everything i think i am going turbo or weber,mods deserve the money but later you are going to see a long list of stuff that you bought for a price of a turbo,but it is your choice in the end MODSvsTURBO.

He is correct, those bolt on mods really are a waste of money, the HP per dollar just doesn't add up. Save up for a turbo or BB kit, or do nothing and save even more money.

I dont think its much different maybe 4 or 5 hp, mostly because of the pistons. He told me the 12.2 pistons for good for about 3 horsepower, so with the big valved head a cam this should be some safe numbers. But I know Darrell could tell you the hp difference and answer any other questions you may have.

Do the 20hp really deserve the money?If your rzr has 30hp 30+20=50 so dose 50hp deserve the money?you could triple your horse power with a turbo 30x3=90, it is your choice at the end, i am now saving for weber or a turbo.

I think everyone is talking about crank HP, not wheel HP.
Stock RZR has about 50HP give or take 3-4HP.

The Holz big bore kit is reported to put out about 70HP I think. A pretty good option for the trail guys in my opinion.

The sand duners will get more bang for the buck from a turbo.

If you are feeling you were feeling a bog,ie not enough power on a trail type hill...let me guess they were climbing in high range? Just use low....might not be real fast but should climb just about any trail hill in low without bogging..you'd loose traction before the engine bogged..
Maybe a good clutch kit...other than that...leave the bolt on's IMO...

BTW the turbo isn't just for the Dune guys..I think the turbo is actually great on the trails..I get part throttle boost all the time climbing hills...it is definitely a different machine..in a good way. I can use high on those hills..lol

What about a ZEX Nitrous kit running a 10 shot. Not a lot of money and at that level you should not be going through a lot of gas and if I understand correctly, that level is still pretty safe on the engine without other mods. Anybody have any real world experience with this set up?

Yea was running high range on the hills. Don't think low range would really be a option. Ideally what I need is a middle range ie: a little lower low range, something splitting the current gear ratios, and high range. Yea their were some 5.0 mods that offered great seat of the pants power for the price paid but alot that were not. Like i stated, i'm new to the rzr world and hunting real world op for bolt on mods hp offering. Most have stated that my money would be better saved for a turbo/bb kit, right now neither of those will be possible.

Has anyone tried the S&S air intake system with or without their exhaust and ECU? They claim 4 hp just for the intake. I am also a tight and twisty trail rider and also don't have the cash for a turbo either. Would like 12-20 more hp without breaking the bank!!

Why was low not an option? Too slow? How fast were yall running?

Anyway,A clutch kit can help. I'd call one of the clutch kit companies and tell them what you want to do
I'm guessing You'll likely have to get the engagement rpm up pretty good.
