Been dialing in the clutch on my 2010 Rzr-s Turbo

Here are the specs

im running factory tires and wheels
Team Secondary
65-63-62 Helix
stock polaris belt
Red/yellow primary spring
lime green/silver secondary
super tip adj weights with:
67 base
14 grams on the heel (7 on each side)
2 grams on the mid (1 on each side)
2 grams on the toe (1on each side)
85 total
when i started i originally had
14 on the heel
4 on the mid
4 on the toe
89 total
so last night i removed 1 from the mid and one from the toe and it pulled harder, so i removed 1 more from the mid and one more from the toe i felt it was running pretty good but still was more top end biased so tonight i decided to run it against my friends 2010 Rzr-s that is bone stock

out of the hole he beat the crap out of me and stayed 1-2 rzr lengths in front of me and im seriously going WTF until about 55 it has a distinct "shift" and i start pulling on him hard but we run out of road.. this has me kind of confused but driving his i can tell its in the clutching of mine, so on a flat road he can beat me but when even on my original setup if we went out to sand mountain (little sahara utah) i can make it straight up the valley with 2 people and he has to zig zag riding alone.. so i know i definitely have more power i just need my clutch dialed in right..


my questions are :
am i going in the right direction?
is a belt upgrade needed?
is the belt slipping?

and also any other input is greatly appreciated

what rpms are you seeing?
for dune climbing I adjust mine to shoot up to about 6100-6200 rpm and stay there (just below the soft limiter on my RZR-S).

if your rpms are climbing slowly then you need to adjust.

I take it that isn't the stock helix? I have always run the stock helix, but I know that different helix angles can change how it shifts.

rpms never go over 5400-5500 until about 55mph then it slowly starts pulling into the 6k range

no ive never had a stock helix, i have a 2010 so it came with the rapid reaction secondary, my turbo clutch kit is from bikeman and the helix im running is what they sent with it

Ok, I would take more weight out of the primary and see if you can get the rpm's up.
If that doesn't work, you might want to consider a team roller secondary.

Better clutches like the Rage 3 from STM might be a good upgrade if you want to throw more money at it.

it does have the team roller secondary, im going to try pulling some weight if that doesnt do it i think i may need to go back to the stock helix, anyone care to explain exactly what the stock helix affects?

The angles on the helix change how the clutch shifts in and out. Easier, harder, etc.
You can also get backshift angles and notches for stronger engine braking for going down hill.

ya, your rpms still look a little low...
Where did you get the red/yellow primary spring?
I wonder if it is too heavy. you are already using pretty light weights for a turbo.
what is the engagement rpm? if it is pretty high, I would try a lighter spring. You can't go too light, or it will start to engage at idle.

I was using a red spring from EPI, but running 11psi of boost on a 8.9:1 engine and 89grams of weight with a lime green secondary spring and stock helix. All of my testing was on sand.

the spring is from team it says 35-140?
the point of engagement where the rzr starts to move is about 1500rpms
the only other spring i have besides stock is the yellow polaris spring

how much difference does the sand make?

hmm, on the Team site it says that spring is 35-140 for kawasaki and 56-140 for polaris.
the red spring from EPI I was using is 35-140.
your engagement at 1500 rpm sounds about right.

sand will make a huge difference over hard ground. On hard ground you have a lot more traction.
