Nitro

#1
Anybody been crazy enough to try and run around 50% nitro in a flattie? It will take twice the fuel volume of alky to do this. Is there a carb that has large enough passages to handle this?

I don't know about 50%, but on youtube there is a few people claiming to have run it that high. Out here I have seen as high as 30% in a flathead. And they was using a Mikuni carb

The increase in thermo loading useing "yellow engine killer" is bad enough with water cooled engines. A real problem with air cooled engines is to be expected, especially if the % get that high. Yes, dragsters get away with high % but the engines only run for a few seconds.
