Tp orange or midnight blue for n/a viper

[Alsim]

In my application I run 49/45 helix and I very like it. It's a monster in the mid and push hard.
My primary is cool but my secondary is little hot with the orange set at 3-2. The midnight blue seams to works well at 6-1 .

Will I have better result on top end and cool deco dart with orange set at 3-1 or 3-0 or keep the midnight blue ?

If you hit the correct rpm on top and held or gained rpm with speed you will gain nothing on top by changing the secondary spring.

I think the orange is too stiff but may be work well set at lower twist with my helix or ....more twist on the midnight blue. Between these 2 springs which are the most efficient for my 49/45 helix ?

I want less heat in the secondary too and lower a bit in rpm

Lonn told me with heavier snow run orange at 3-2, if riding smooth hard pack trails then you can go 3-1. You may want to test it to see if satisfied.

Hi rbell!
Did you tried the midnight blue before ? What did you notice with the orange?

 

[rbell14]

Presently running mid night blue spring at 6-1. Happy with it's performance.

Have not installed the orange yet but will do so within the next week or so.

Tell us what you will see between the two after testing

I tested it at 3-1 today with my wife sit on the barber chair at the rear. They pull hard from 8500 to 8950 and I reached 82 mph in a short stretch in the loose snow. The secondary was cool and primary was warm. I had better result with xtx belt vs gates (8dn).

Alsim, which belt are you running? I'm about to test a new 8jp gates carbon fiber and will then do the secondary spring so I can isolate the changes.
