For many classes and national events, both the fuel and often the fuel supplier is specified. In that case, there is no fuel choice. However, for many others such as local bracket racing gasoline setups, that is usually not the case. The selection of gasoline is first dependent on leaded or unleaded. Racecars driven to […]
E85 is examined as a racing fuel. E85 is a combination of ethanol and low octane gasoline. Some racers report more power from E85 than from methanol. On the other hand, when the Indy Car League converted from methanol to straight ethanol, dynamometer tests revealed a reduction in power after the conversion.
A lot of pit buz that cooler fuel runs better. METHANOL VAPOR ISSUE: We found in our methanol publication development that only methanol vapor burns.
Dyno results just in from one of our customers on his new twin turbocharged alcohol Big Block: dyno’d 2,500+ HP at 25 psi boost with a turbo setup capable of 50 psi boost. He reports that the most boost that he is currently seeing in the installation is 35 psi, blowing the tires away on […]
Question: What is pure methanol? Answer: If it is sold as pure methanol, it is supposed to be well over 99% methanol. It is a baseline compound that should behave the same regardless of supplier unless it is mixed with something else such as a top end lube or it is contaminated.
Question: Can methanol be stored for a long period of time? Answer: Methanol absorbs moisture. So if it is stored, it must be in a sealed container. Plastic is microscopically porous and does allow for methanol moisture contamination if it is stored a long time or (in some cases) if the container is dipped in […]
Question: Methanol for both IHRA and NHRA Drag Racing Answer: Both organizations test methanol with different methods. If you have fuel that passes one organization, it may or may not pass the other organization all of the time. I met the fuel check supervisors for both organizations when I was developing 5000 Horsepower on Methanol, […]
Question: Top lube? Answer: Most racers I have talked to have good success with top lube to inhibit corrosion. Some previous info mentioned some accumulation over time. The reason NHRA and IHRA do not allow it in fuel checks is they cannot distinguish between power enhancing additives (illegal) and top lube in their tests. So […]
Question: Can we put an 8-71 blower on a high output, normally aspirated Big Block V-8 with very high compression ratio (15 to 1)? Answer: The detonation can be controlled with enrichment and air to fuel ratio control, theoretically regardless of the compression ratio. However, I am not sure about the mechanical strength of the […]
The following comes from JB in the UK: Just a quick note to say thankyou for producing a fantastic source of information with the Fuel Injection Secrets book.
