Yeah, I'm not sure. Just pulling from old notes when I was trying a bunch of springs. I'm sure Knapp will chime in.

Deleting post so people don't get bad info as Mike has posted the correct numbers on page 3.

Someone else can help you more than me I'm sure. Just remember the primary and secondary fight each other. Making a change to one has an impact on the other. For example... Let's say your secondary is way off and does not open at a reasonable rate. (Stiff spring with high degree wrap) Your RPM's...

lighter twist will lower rpm but also decrease side pressure. I doubt you are actually slipping the primary, but I'm not an expert. I'd go up and down 10 degrees on the secondary and see what belt temps tell you. As for Dalton.. They have a nice chart on their site that is helpful to compare rates.

Sounds like you are close and have a belt temp gauge. Why not play with secondary and watch belt temps? Keep in mind any changes will change RPM. Weaker primary spring = lower rpm, but so does same primary spring and heavier weights. I'd increase and decrease the secondary by 10 degrees at a...

I like the one from barn of parts.

Yeah, stock 8JP. Bought the sled used though so anything is possible before we owned it.

2014 Viper with ~4k miles. The movable sheave has some wear. I'm surprised with the lower miles but it's clearly wore. How much is enough to really affect the shift? This is my daughters sled so don't need top performance.

Hmmm so why mess with an adjustable regulator? Somehow is self adjusts for ~200 hp difference?

That’s what I don’t follow. At the same pressure how is more fuel delivered?

I see Hurricane offers a pump upgrade with a new regulator but it's not adjustable. They say it's good to 500hp and is designed to run at stock pressure. I don't follow the logic. What am I missing...

Yeah that's why I was asking how you did on snow. You must have made a bunch of runs with the snow we had.

@Doc Harley How did you do on snow?

If the sensor is not reading it will go back to the default tune. If the sensor is reading but not accurate, there would be no programmatic way the tune would know without another source to go off of.

What mods do you have to your sled?
