Product Information

The Force Turbos Polaris 800 VCS Turbo System is the high-performance, zero-compromise turbo solution you have been waiting for. Powered by the VCS (Velocity Control System), we are able to eliminate fuel and air limitations seen in traditional turbo systems. By electronically maintaining and balancing manufacturer stock air, fuel and exhaust velocities we are able to maximize the bottom-end and mid-range response you would expect from a naturally aspirated engine while adding the top-end power of boost.

With its lightweight design, the Polaris 800 VCS Turbo System adds less than 12 pounds.

The installation of the turbo system is simple and doesn’t require any modification of the chassis or re-flashing of the ECU.

Performance Expectations

  • This system will take your snowmobile from approx. 145 hp to approx. 200 hp and above with higher boost levels.


  • Base fuel mapping included. Digital fuel controller tuning required for specific machine setup for optimum functionality.
  • For diagnostics and tuning AFR and Boost gauges recommended.

Boost Level

  • Turbo system comes preset from 3-10 psi with the ability to run up to 12 psi.

Fuel Considerations

  • 91 octance non-ethanol fuel is compatible. Force Turbos recommends running race fuel for more reliable performance.
  • Initial tank following turbo system install: 110 race fuel or equivalent
  • Boost levels from 3-4lbs: 91 Octane with no more than 10% ethanol
  • Boost levels from 5-7lbs: Mix of 50% 91 Octane (no more than 10% ethanol) with 50% 110 race fuel or equivalent
  • Boost levels from 7lbs and up: 110 race fuel or equivalent
  • Anticipate higher octane mixtures required for low elevation systems (from sea level to 3,000 feet)

Depending on boost levels, quality of fuel available, and other factors, the rider can consider experimenting with increased pump fuel ratios as long as you use extreme caution, and look for warning signs.  Indicators and warning signs to look for to ensure your fuel mixture is in an acceptable range for proper engine operation can be: Engine detonation, loss of power, above normal engine temperatures, loose or broken spark plugs cause from detonation and general performance problems.
