My busas stock geared would be turning 4k @ 80mph.
My zx10 turns 5k (stock geared) to go 80 mph.
Which is using less gas, the bigger motor turning slower than the smaller motor turning 1k faster?

wihtout going into details, BSFC (brake specific fuel consumption) is the most efficient at the engines torque peak.

Lowest fuel consumption is commonly found at the highest vacuum peak.
 
well if you just go by the math part..

The Busa is burning more fuel IF A/F ratio is identical..

Busa needs to turn about 3846 RPM to match (all via the math part)

now factor in the loads to work out A/F? good luck...


If train A leaves station C at 3PM and Train B leaves staion 4 at 4PM. what color are your socks?
