Can I run 4lb of boost at sea level in my Silber setup on 91 octane non ethanol? If so where do I get the spring? Also what's the most boost I can run at sea level safely with a 50/50 mix of AV? And what boost can I run on 50/50 at 6k feet?
Axys Silber turbo 4lb waste gate spring
- Thread starter Coldestwinter1
- Start date
This is where I bought my 5 psi spring.

Looks like a 3 psi spring is the next step down.
At elevation it seems like most people run 5 psi on pump gas and at 7 psi you need to start blending with AV or race fuel. 80/20 is a good place to start.

Thanks I'm running a 3 now and have a 5&7 I bet they don't make a 4lb spring
You could use an in-line boost controller to get to 4psi. You will need a boost Guage though if you haven't already added one.

Hallman make a good reliable manual boost control.
The 3 pound spring will make 4-4.5 in our application.
I was thinking the same snowmow, if you are going to invest that much money in a turbo why not run at least 7 pounds of boost.
Just so I'm clear I can run 5lbs at 1500'? And if something is not right will the sled kick the det warning before I burn it down?

Yes your det sensor will kick but you won't have any issues at 5 lbs. I ride from my house at times and that's at 1000 feet no issues ever. Call Justin at silber he will tell you what to do. If you're really nervous about it put gallon of AV gas or race every tank but I've ran pump all year at 5 lbs
I would be careful running 5 on pump at that elevation and I dont think these Axys sleds throw the DET code like the Pro did... Well not as easy.
In some cases the pump you buy really does not have enough octane for a stock sled, just be careful.

That's it? Does that boost level come with a skirt? Or a free pass to the transgender bathroom.

I started mixing a gallon of AV at 5 lbs at elevation just to feel good about it but ran whole season from elevation to 8000 ft on 5 lbs and 91 pump never seen a det light thrown or missed a beat.. That's what Justin at silber said to do... Play it safe run 3-4 lbs but if you gunna spend couple grand on boost you should make it worth it!
