Matt-itude Regular Location: Perth, Western Australia Registered: October 2004	Higher RON Fuels: Did you know? Sun, 12 June 2005 09:11 This came to my attention the other day, There is no difference in the calorific value of the different types of RON fuels. This means there is no internal engergy difference between BP Ultimate 98 and normal pump fuel. So if you dyno'd BP Ultimate vs. Regular Unleaded on a stock car there really shouldn't be a difference in torque or power output. The advantage to using a high RON fuel comes in with it having a higher flash point, or a resistance to detonation. This means engines can be run with a higher compression ratios, and can advance the timing to the limit of detonation, and produce much higher peak pressures and temperatures in the combustion chamber which will increase the thermal efficiency, and therefore increase overall torque and poer, compared to regular unleaded. Better performance from BP ultimate? All things staying the same, i don't think so. [Updated on: Sun, 12 June 2005 09:22] [Report message to a moderator]
