Fuel comparison tests were performed on three leading brand high octane fuels, Shell V-Power Racing and two Premium 98 Octane fuels (brands X and Y), under strictly controlled conditions. Tests were performed using a current model Mitsubishi Evo IX 2ltr turbocharged engine* mounted to a purpose built engine dynamometer cell. Tests were conducted using the standard Mitsubishi ECU and a MoTeC Plug In M800 ECU. No modifications were made to the engine.
The results of the testing clearly indicated that:
Tuning of engines is required to obtain the maximum benefit from any fuel.
There can be significant performance benefits to the fitting of a MoTeC Engine Control Unit (ECU), even without engine modifications.
Shell V-Power Racing 100 Octane fuel consistently delivered significantly more torque (up to 10.7%) and engine horsepower (up to 4.6%) than other commercially available high octane fuels in the retail market.
In addition, based on limited testing, Aviation Fuel (Av Gas) was also tested.
Initial results showed that V-Power Racing was superior in its detonation resistance and able to make more power than the tested Av Gas.
