Shell v power racing 100 ron woohoo
Shell V-Power Out Performs The Others!
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 an 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, limited testing of Aviation Fuel (Av Gas) was also carried out. Initial results showed that V-Power Racing was superior in its detonation resistance and able to make more power than the tested Av Gas.

omfg look at the torque and hp increases just from the fuel Zmg!!1

Good read but the fact of the matter...
Is that there is no reason why the results achieved with the Motec ECU couldn't be achieved with the factory ECU. They could have modified the factory ECU using ECUTEK or open source reflashing tools to get similar results. Of course the Motec procedure is much easier and data logging capabilities are better (I know this being an ex-Autronic owner with a Subaru STI Spec C), but it is important to understand this is not something only a Motec ECU can do.
Interesting that Shell V Power makes such a big difference at 20PSI especially at maximum volumetric efficiency (35lbft of torque) - shows that at peak cylinder pressures the superior octane rating of Shell V Power is significantly more detonation resistant.
The other important aspect that is not mentioned is whether or not they modified fuel mixtures. If they did, they could have run a reasonably lean AFR (e.g. 12:1) which would been reasonably OK with V Power but would have caused issues with 98RON fuel.
P.S. Sykotoy, did you manage to scan in that dyno plot?
