I think I do have my work cut out for me but I also don't think the smallest engine is always the most fuel efficient. At 65 mph my engine is only turning about 1400 rpms. How fast does a 1.0 liter have to rev with factory gearing at 65 mph? Did you know that double the rpm quadruples the amount of rotational friction an engine experiences? I forgot to mention that I'll also be using reverse flow cooling and a
propylene glycol based coolant that will allow me to run coolant temps at 240 F further increasing atomization and reducing chamber hotspots.
