Ok, so my question is if i have say 14:1 compression and am at say half throttle, would my compression be equal to an engine with 7:1 compression at full throttle?
Now I'm asking this question in relation to this idea I had. I was thinking if i could run alcohol at anything over say 75% throttle and gas under that then i could run really high compression and also possibly avoid the contamination and rust issues with alcohol.
Heres how it would work. You have 2 fuel tanks, one gas one alcohol. Your gas tank uses the stock pump and the alcohol tank uses a really good pump. The line from the alcohol pump has an adjustable fuel regulator and you set it to something like 100psi. Idk the exact psi you would use but you would want it so that you get the correct A/F ratio with gas and with alcohol using the same ecu settings. This would prolly be the hardest part.
Then the two fuel lines merge into one then go into the fuel rail. Where they merge is a gate type thing that will only let one go through, so if the gas is going through the alcohol is shut off and vica-versa. Whichever line has more pressure is the one that goes through.
Then the only thing left is you make a switch so that the alcohol pump is turned on at 75% throttle and voila ur running alcohol when the dynamic compression gets high and gas when its lower!
Let me know what you think
