is there a max mph that we can get out of the ranger? just wandering if there is a max mph relitive to rpm and the sheeves.

P.S. I don't need anyone posting that i don't need to go faster or that it is unsafe. Just want some replies from those that have some usefull input. thanx

With the SP ECU I hit the rev limlter at 52 MPH. If the rumors are true about Big Gun ECU with Modded rev limiter that will change.

my deal is this, with the turbo i can hit the rev limiter in 550ft at 44mph. im not sure what a "SAFE" rpm is with turbo. Im experimenting adjustable weights right and im at a total of 81.5g. i think if i am still hiting the rev limiter i need to put more weight at the tip to get more mph. that is why im asking if there is a terminal velocity between rpms and sheeves.

Going that fast is unsafe if polaris wanted it to go that fast they would of made it do it already. Just Kidding so you still need more weight? I think were going to outlet center on sunday if your in call me at the shop.

Im trying to understand here with a turbo your only pulling 44 out of 550.The reason im asking is we are pulling 46 out of 300' on nos and i never hit the rev limiter.is this because your running stock size tires or what air presure are you running i would think it would be a setup issue not a clutch weight issue.And the reason i say this is when i hit the nos she almost stands up. It engages my clutches twice as fast due to aggerssive rpms .I would think your turbo spooling faster should grab them clutches hard.?? i would also think if you backed off your rev limiter and slowly went at the top speed you will answer your own question.I mean by slowly gathering your speed taking the rev limiter out of the game you should find your the max speed of your gearing then.Alls you have to do is figure out how to get there quicker without upsetting your rev limiter.Also some food for thought turbos and superchargers are fast not quick.That is why we run nos on our turbo nitrous ds.too make it quick and fast.The nos is the quick and the turbo is the fast.

You don't need to go any faster, since it sounds like you will never catch me, since the gear change I have no idea what distance it takes but I can cruse at 45mph down sand highway and hit 52mph on the dirt roads and I am no where near the rev limiter, I am also running near stock clutching so you need help.

There is No Replacement For Displacement.

yeah i know, let me see you find someone here in s.cal that knows something about these clutches rather than the kids that work at the dealer. if i back off the gas to about half and try to feather it i can squeeze a few more mph but thats it. my guess would be that something isn't lined up right down there.

I changed the primary spring and put the Team secondary and improved my bottom and Mid but lost some top end performance. Dale from Bikeman recommended changing the Helix in the Secondary over messing with the clutch weights to get my top end back. Dale is pretty sharp on the clutches but I would also love to find a local source here in SoCal.

Yeah, if you call Dale at Bikeman and tell him exactly what you're running and what you want to achieve, he will be able to tell you exactly what you need. Give him 20 minutes of your time. You won't regret it.

I would say yes, there is a terminal speed you can get with any particular gearing. Sounds like you have more than enough motor to pull higher top speeds, you just need to maximize your clutch performance first, then start working on gearing if you are still not satisfied with your top speed. And Dale will be able to modify your clutch setup to match your gearing as you step up.

Going downhill, (okay, a big hill) our ranger would hit the limiter at about 48-49 and would clock 49.2 on the gps(could never quite get that magical 50!). In the real world, it would cruise on level ground at around 44-47 mph, but doesn't have the power to get neer the rev limiter. It's a stock 700, althouch I recentaly put in a sp belt, with 27" tires.

With your increased power, you should be able to hit the rev limiter all the time, and I would expect your top speed to be over the 44 it's supposed to go.

I would guess that you might have one or more of the folling issues:

your clutching is off, which I don't know how to fix.

your belt is worn. On an old ranger we had, just putting in a new belt gave us 3 mph over the worn one. And weren't you having belt slipping problems before? You may have worn the belt.

Belt slipping. I have heard that clutching and sheeves can help with this, but don't know how to fix. I have heard people here talk of the dragonfire belt, but haven't really heard anywhere of anyone really impressed. Just the other day I heard of a new performance belt made with, I believe, carbon fiber, that is supposed to grip better, slip less, run cooler, and last longer. I don't know who makes it, I'll see if I can find out.

You problem may just be what mine usually is-loose nut behind the wheel!

Good luck!

oooooooookkkkkkkkkkk, so what is the top speed stock? new belt gets me 48mph. I think im going as fast as i can with this gearing and rpm because when it hits the rev limiter the front end does come down. It seems that if i didn't have the rev limiter that i could get some good speed. Even after i do feather the gas to pick up a few more mph, Im only feathering it at about 1/2 throttle. So Chuck, what was your top speed before the gears?

Before the gears it was 52mph and bouncing off the hard rev limiter and after the gears it was 52mph and no sign of the rev limiter, Im going to reinstall the tach.

Once I get the tach back in Ill know how far I am from the rev limiter. Who knows how fast it will go when it all gets put back together.
