Well how much fuel is my 03 Ford Explorer 4.6 in 5th gear (overdrive) into a 3.73 rear end using when I drive it at 49MPH which is 1500RPMs and it shows it is getting 30MPG?? Steady running…how much HP and torque is it making?
Also same question for a 2000 Mercury Grand Marques, Well how much fuel is 4.6 in 4th gear (overdrive) into a 3.27 rear end using when I drive it at 65MPH which is 1700RPMs and it shows it is getting 30MPG?? Steady running…how much HP and torque is it making?
Same car running a 16.4 A/F ratio gets 35MPG same specs.

Trust me I know what BSFC is.
I'm not going to play this game. Been here and have done it 100 times, probably 20 times on this forum. If I we're to play your game you left something major out... "engine load" I would need to know what it is and it can be measured in kPa, inch/hg or psi I just need one of them to solve for it.
As far as the Mavrick guy. I had the inputs I needed.
Fuel type
Load inch/hg
IAT's
DA
AFR
BSFC load Map for a 302 Ford
Bore
Stroke
Compression Ratio
RPM
Rod length
Ignition timing BTDC
Cd
Transmission type
Anyway, I hope you find what you're looking for and prove me wrong. Like I said I already tested a vapor carburetor on my lawn mower engine. My results were no improvement in fuel consumption. Same EGT's and cylinder temps with the same AFR.
Good Luck
