I'm wanting to get everyone's thoughts on blending 93 AKI non-ethanol pump gas with a blend of methanol and nitromethane. The blend ratio would be 9 gallons of gasoline to 1 gallon of 50/50 methanol/nitromethane blend. (VP Nitro 50-50) The use of this is a max effort NA drag racing engine that rules stipulate the fuel must be 90% gasoline. (free reign otherwise)
Here's my calculations of the effect of this blend. Now I know this may not be the actual result from the blend as different components of the fuel will act in different ways when blended. But, this should at least be ballpark.
BTU/lb of air
Gasoline = 1274
Methanol = 1328
Nitromethane = 2049
Stoichiometric Air/Fuel Ratio
Gasoline = 14.7
Methanol = 6.47
Nitromethane = 1.70
Specific Gravity
Gasoline = 0.745
Methanol = 0.795
Nitromethane = 1.139
Blend Ratio
Gasoline = 90%
Methanol = 5%
Nitromethane = 5%
Oxygen Content
Gasoline = 0%
Methanol = 49%
Nitromethane = 52%
Ballpark Blended Properties
Btu/lb of air = 1316
Stoich AFR = 13.64
Specific Gravity = 0.767
Oxygen Content = 5%
The questions I have are about blending and storage.
Will the methanol / nitromethane blend fully blend with the gasoline?
Could this be blended ahead of time and stored in a sealed container for a few months before use?
The initial idea was to blend 8-10% nitropropane or propylene oxide but those are pretty much impossible to get right now so I'm looking down this path. Any input is appreciated.
