      Fuel Considerations

      • 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.
