u will never get a carb to run 20:1 without it breaking up...
lean burn, small jap cars with wideband o2s are the way to get great mpg. well at least till direct injection come out for gas powered cars.....i can not wait to see what can be done with turbos after that...
oh and as for the high rpm no load vs. low rpm under a tiny bit more load... you guys are forgeting all the loss from drive train and valve train. as well as the oil pump having to pump harder at 6 k than 2 k...
low rpms in top gear (without lugging it) is better for mph. [/thread]
