Stock twist

[apexgt4life]

I have a 15 and 18 stock vipers. What is the stock settings for secondary twist and or what should i set at.

I feel they were both set different stock?

I think 15 was at 2 and 6

18 was at 1 and something as my mark rubbed off

If I remember correctly 70 degrees is stock setting.

 

[apexgt4life]

So 1 and 6?

Guees im confused on all the numbers on

 

[Yamajon1]

Yes.

 

[apexgt4life]

Ok any other input. One appears to be set at. 6 and 2

That would be 1 step tighter, 80 degrees. Lower settings will let the secondary open quicker loading the engine a little more and dropping RPM slightly. Higher settings the secondary opens slower and you may see slightly higher RPM

2 -14 Vipers and 2 - 16 Vipers all set at 6-1 from the factory and still today with TPI big Venom kits or Schmidt Bros kit.

That would be 1 step tighter, 80 degrees. Lower settings will let the secondary open quicker loading the engine a little more and dropping RPM slightly. Higher settings the secondary opens slower and you may see slightly higher RPM

Is there are chart on what settings equal what degree? Or is it specific to manufacturer or model?
