But that increase is at lower rpm.   ;)


I just finished reading an article about a 1969 non-Vair musclecar 
with a 400+ cubic inch engine that was retrofitted with state of the 
art electronically controlled fuel injection to compliment it's high 
tech electronic ignition.   Driveability improved as did fuel mileage 
and engine idle and starting, which required only a bump of the key, 
hot or cold.   The car "felt stronger" in city driving.

On the dragstrip, it ran slower than with the carb, and this was with 
an (advertised) 1000 cfm throttle body.   Less top-end 
horsepower.  The performance car magazine made mention of the fact 
that this was "as expected" what with other EFI installations on 
other cars demonstrating similar gains, and losses.

Something about carbs...  ;)
