The determination of nozzles & jetting in a new fuel injection setup can be a challenge.
Decreased percentages of nitro richen the racing engine.
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.
Just a note about our test engine for this year. We put our blown alcohol engine back together for nitro testing this year.
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: Different racers get different boost readings
In our drag racing, we did use air to fuel ratio as a controlled value to get the engine into a linear range. That task is an extensive explanation through out writings. The linear range is where the engine is completely predictable. We achieved that very well in our racing.
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: 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 […]
