The stoichiometric ratio commonly known as the Air-Fuel Ratio (AFR) is really a ratio from the particles of air to the fuel. As you notice about the chart different fuels have different AFR’s. These ratios represent the amount of air it takes to totally burn the specified fuel. These air fuel ratios are extremely essential for dyno tuning because they are indicators of how rich or lean your engine is. For regular fuel (premium gasoline) Rich is considered to be AFR between 1 and 14.7 and lean is considered to be 14.7 or more. To understand exactly what your air fuel ratio is it is advised to buy an Air/Fuel ratio gauge and wideband sensor that exist within our store.
Octane plays a key role in your performance as it can help you or hurt you tremendously. Most know that the larger the octane rating the more power you may make, but why? Back during the First World War we discovered that tetraethyl lead or (TEL) could be put into gasoline to improve the octane rating. Octane numbers would be the quantity of compression the fuel can take before it combusts without spark. For an example 87 octane will combust naturally without spark before an octane rating of 93. Whenever your fuel combusts without spark it creates knock in the engine which in turn causes lack of power and damages your engine. The reason for higher octane fuels would be to keep your lower that allows you to definitely produce more power. Methanol injection is a quick and easy method of upping your octane rating. The advantages to methanol injection are obvious when you sit down and look at the facts. With methanol injection your engine will see octane ratings of 10-25 points higher. If you are using 93 octane fuel with methanol injection you can observe octane numbers between 103-118. Q16 the industry common racing fuel comes with an octane rating of 116 however it costs $16.40 per gallon. Methanol however is around $3.00 per gallon and it is mixed 50% with water so you would really be getting 2 gallons for the price of one which turns out to be about $1.50 per injected gallon. The same octane rating is achieved for any quarter from the cost and the best part about this is you can regular gasoline at any gas station.
