What Indy Specility setup are guys running in their 850 Axys turbos. Tried the turbo 3 heavy weights with magnets as follows. 2 in hole 1, holes 2 and 3 full. They weigh 79.4 grams. Red primary, mountain 1 helix and I’m not sure about the secondary spring. The one I had in was all black and 5-1/2” high, not sure if that’s the spring Dan sent last year for the 800 Axys. At 7 psi and 6500’ was over revving. Had to drop to 5 psi and still ran at 8450 rpm. Was I running the right secondary spring? Sled also felt felt a little soft on the bottom end. The 800 axys with the same kit only just the turbo 3 weights at 74 grams ran on the money at 8400 rpm. Thoughts for improving the bottom end and getting back to the 7 psi spring without over revving?
Ok, I have a few updates that should really help people ( update ) or purchase the correct Turbo kits since we now have a lot more to offer as rider abilities vary so much..... And more and more people are entering into the turbo world.
Mountain 1 & 2 helix's are maximum belt bite least experienced riders ( easiest to handle the sled in the trees with these two Helix's )
The Mountain 2 is one of the mildest Helix's we sell.
Mountain 1 Helix is our go to Helix we sell in most kits ( it's for beginner Turbo riders to mid experienced riders.... ( Hill climbers & tree ) not flat area racers.
Here's where things are in to you guys....
Turbo 3
Turbo 4
Turbo Extreme - very aggressive, for above average riders.
Turbo Extreme 2 - is in the works.... Even More bottom end shift speed harder to hang to handle bars down low ( even more track speed then Ext-1 down low ) - but mid-shift to wide open shift speed slows down for more belt bit.
Mountain 2 helix - spring most often used is 140/200
Mountain 1 Helix - spring most often used is 155/222
Turbo 3, & Turbo 4 depends on boost and rider ability.
Turbo Extreme1 - spring most often sold ( Black/Purple )
Turbo Extreme 2 - spring will most likely be 155/222
Our Website is in process of updates to help facilitate these kit updates.
Note of caution....Mountain 2 & Mountain 1 Heliex's are targeted for high elevation ( Climbing & boondocking only ) not drag racing your buddy on flat ground. They have The best belt life...... Neither kit is designed for holding sled wide open on flat ground with stock or lower gearing.
Also Note - Long factory center to center distances can cause the belt to hit the bottom of the driven and cause full throttle belt slipping...... It's always dangerous to hold under geared Turbo sleds wide open throttle on flat ground with little load form low gears...... If you have blowen belts at WOT most often your driven clutch ran out of travel.
Almost all Turbo sleds now days are geared to low......
So before you jump to any of our more aggressive helix's keep in mind that more often then not people would be better off gearing up and running our Turbo 1 Helix..... For maximum belt life and track speed.
Why are there an increasing amount of Helix's choices ?
Because the turbo clutching keeps getting better and people keep are talking to each other and tweeting what they have for there area and elevation and riding style and rider weight.
If you chose to run Polaris stock gearing and you are a fairly aggressive rider you might have to move into more aggressive helix's then the Mountain 1 & Mountain 2
Our Mountian 3, 4 Helix will be getting Re-branded as ( Turbo 3, & Turbo 4 ) and so on,......
Turbo extreme
Clutching will forever be confusing....... And vary center to center distances will always raise hell with trying to figure out .... ( WHY ) your is just a little different to tune then your buddies.
I hope this helps......oh and sorry for this ( we will never post our helix numbers ) and mountain 1,2,3,4 has not logical increase.... I will say this.. our mountain 2 is one of the slowest shifting helix's we sell....Max belt clamping.
Sorry I do not monitor clutching threads all that often..... Reason being..... I do love clutching but you can live on a clutching thread and never be able to sleep again.
So forgive me if I am not back for a while.
Happy Turbo riding !!
And thank you to everyone that runs our kits.
Dan
