|Is it ok to mix race gas and pump gas with Brock's maps?|
|Answer / Solution|
The short answer is NO.
Back in the old days, racers would mix higher octane race gas and pump gas to prevent detonation (ping) in race bikes OR because they mistakenly thought they we making their stock bikes faster. Today, we know that the only reason a higher octane ‘race’ fuel is needed would be if you have high compression pistons installed or are using a power adder such as nitrous oxide or turbo charging. Modern sportbikes are designed for a specific (readily available) octane rated pump fuel, usually to 87-91. If you decide to run a higher octane race fuel, let’s use 100 octane as an example, power levels will suffer unless the fuel has been intentionally treated with additional Oxygenates to produce more power from the fuel manufacturer. Even higher octane ratings will produce a corresponding decrease in power, we have noticed 15+ horsepower decreases in stock Hayabusa’s when using 116 octane race fuel. Mixing race fuel with pump fuel not only harms power levels, it disrupts our mapping.
Note: VP’s MR12 is the hottest oxygenated race fuel available today.
You will notice it has an Octane rating of 87. This is the preferred fuel for use with all Brock’s Performance TRACK maps.
