How do I read this helix?

[Fro]

RX-1 helix...my finger is at 0...it has a 3,6,9 also stamped on it. Do you count the holes to the left? If so, why only 4 holes?

 

[Fro]

Also, there are spots that look like you could drill them to get the wrap you need...yes/no?

The inside of your secondary will also be marked with the numbers 1,2 and 3, that way combined with the Helix numbers you mentioned and the spring ends indexed into the proper holes of the Helix and the Secondary you can determine your degrees of spring wrap.​

​

For instance Helix hole 0 and Secondary hole 1 = 10 degrees of wrap​

​

To the extreme end you have Helix hole 9 and Secondary hole 3 = 120 deg of wrap​

​

The wrap degrees determins belt sqeeze which aslo will dictate upshift speed and downshift speed. The lower the degree the faster the upshift, the higher degree the faster the backshift, also if you have too little belt squeeze (low degree of warp) you will have belt slipage. These adjustment will effect your shift RPM as well.​

Most stock sleds usually will run in the range of around 70 (holes 6 and 1), there are too many variables involving Helix's and springs to get too deep into this but that should answer you question I hope.​

Same as any other helix
0=0deg.
3=30deg.
6=60deg.
9=90deg.

Then you look on your secondary where the spring goes,there will be 3 holes marked 1,2,3.
Heres some exmaples:
Helix Hole 3 + Sec. Hole 2= 50deg. wrap
Helix Hole 3 + Sec. Hole 3= 60deg. wrap
Helix Hole 6 + Sec. Hole 1= 70deg. wrap
Helix Hole 6 + Sec. Hole 2= 80deg. wrap
Helix Hole 6 + Sec. Hole 3= 90deg. wrap

I think I was just missing something. So the # next to the hole is it. I was thinking it was a clockwise deal with more options...my bad.

You can drill extra holes in the helix for optional secondary wrapping options but u gotta know what ur doing.

Expert's example is much better than mine! and much easier to read LOL
