UTV's and ATV's general discussion.

This battery BS is derailing an otherwise nice thread (and I regret contributing to it, though I did try to relate information without attacking anyone.)

I respectfully suggest we all give it a rest and discontinues the pissing match... or start a new thread to debate how temperature affects battery capacity.

Some of the Polaris models used to freewheel below a certain speed so the “trick” was to touch the gas to keep the RPMs up and keep the engine brake engaged.

Yeah, it was avoiding exactly that that made me cross the Polaris line off my list. Such a counter-intuitive driving mode: "I need to go slower, so I'll step on the gas" is just not a natural reaction when I'm putting along down a hill and the driveline suddenly shifts into freewheel. I wanted something more predictable in it's response. I could eventually get used to it myself, but I'm not the only one driving my machines.

Glad to hear Polaris is at least offering an option that addresses this. @deserteagle71 , do you know if they offer it on all models, or is it just an option on their higher end machines?

I've got two antique Coot ATVs that do that. They originally shipped with a Tecumseh engine that idled around 800 RPM, so the comet clutches were set to engage somewhere around 1000 RPM. I bought one of them where the previous owner had replaced the drive part of the clutch/CVT system with one from a snowmobile of a similar era. It looked the same, but it was set up to engage up around 1800 RPM. The brake system is weak on these units. I got quite a surprise when I took it out for a spin and the clutch released at half speed, rather than close to idle. Fortunately, the worm gear drive system still provided a bit of drag. I did still smack a tree when it first let go on a steep, winding section of trail.

I have a 2018 Polaris Ranger XP1000, it came stock with the EBS, and you do not have to step on the gas to engage the braking, you only have to lift your foot and it slows down very quickly. I do see on the Ranger 570, that EBS is not provided and would be an option. It appears to be a standard feature on the higher end models.

I don't know just which models have it and which don't. Our new Ranger XP1000 the County bought for our Search and Rescue unit does not. I subscribe to a UTV magazine that regularly tests all kinds of side by sides and quads and they regularly talk about the lack of engine braking in various Polaris units...also how they don't have actual 4wd, only AWD which only activates the front drivetrain if the rear wheels are turning faster (spinning) than the front. Here is an excerpt from a test they just did on a fancy new RZR 1000:

John, I have almost bought 2-3 coots over the years. Last one had a small diesel conversion that made you slightly nauseous due to vibration

They are fun, quirky little vehicles. And you can really freak a passenger out by driving it into a pond: It just does not look like an amphibious ATV.

Ya, stuck with the Rokon, Quadractors and trikes

I got enough issues

Intercoolers are used on turbocharged or supercharged engines because the compressed air rises in temperature. Cool it a bit and once again one can get more air mass in the combustion chamber.

Actually, intercoolers are used between two power adders, be they turbos or superchargers, but usually its a turbo followed by a supercharger.

Bottom line, as the name strongly suggests, an intercooler goes between the two. Otherwise it's a charge air cooler.

Did you post about your Quadractor on here before? Ever since I was a kid. I thought they were incredibly interesting.

Where are you from? I'd love to see your collection, if I'm ever in your area.

I’m sure I did!
