Holden Engine Efficiency

[Cheap6]

While power output will increase with engine speeds above maximum torque, an engine will always be most efficient where it generates maximum torque. It might be interesting to calculate the BMEP at maximum torque for each of those engines and see if the ranking changes.

Ah the '66. From the era of free-love and 'shroom smorgasbords. Fluffy was built with the right to answer for nothing, least of all efficiency, only to be concerned with opulence and indulgence.

Why you no thread Ari?

no im serious, am i doing something wrong here?

BMEP = kW x 1200/litres x rpm

bmep = 216 x 1200/7.4 x 4000

I get 8.75 for yours.

259200 / 29600 = 8.75

math is stupid

math is stupid

well technically going by the formula im getting in the hundreds of thousands.

you know. division before multiplication.

BRACKETS people. use them dammit!

now stage 2. lets look at pure maths and how it interacts with the world around us
lets see if somehow we can relate that to an engine and its efficiency for better accuracy

The BMEP is based around design efficiency, not fuel efficiency.
