    I worked with a motorcycle racer years back and they did some extensive studying on airflow vs fuel used and he said that 62 mph was the...

    Welcome to my 09 Esky 6.2L in town driving on e85 I wanted a 10 SP for Xmas but they only had 6 SP last year.

    26 mpg@ 63.. 23 mpg@ 66… level ground 70 gets about 19 it’s aerodynamic drag Never see much about the shutters in the grill !

    I find it interesting that most normal people driving as they normally do, tend to get less MpGs / consume more fuel per unit of time...

    So a 6.2 isn't a 6.2 until WOT. Until that throttle position, it is the same as a 5.3. I tell ya...what a rip off. To pay a premium...

    Put a 6.2 on an engine dyno. See what power it makes at 14.7 afr at 1200 rpm. Record mass air flow and mass rate of fuel flow. Put 5.3...

    Good question @swathdiver . I'm about done with all the engineering classes here overcomplicating things. We have everything from a...

    It feels like I'm living in a real life episode of MYTH BUSTERS......we just need a lab to hash this out. LOL

    My reply was based on you saying that 10 cc of fuel in either engine would make the same power. The AFR can't be the same with 10cc of...

    Now we are getting somewhere. If p is 70 then you can have a 6.2 ( numerator) displacement with higher afr ( denominator) and make...

    If you are maintaining a given power level (like say that 70 hp cruising example) and change any of the terms in either the red or blue...

    Even looking at just the fuel mass flow, it says the same thing: 70hp ( your example) requires a given fuel flow. Ok so make that a...

    In this instance, a ratio of 14.7:1 will never be the same amount of fuel in each cylinder just due to geometry (volume). If you put...

    Engine Power equation See equation on slide 4. nv is VE, Vbdc is engine displacement, AFR is air/fuel ratio. For the power required...
