Mechanical fuel injection is holding its own against EFI and racing carbs in racing. It is simple, lower cost in many applications, and good for fuel pressure increases for more response & power. One recent application tested racing carbs, EFI, and mechanical fuel injection all on the same racing engine. Another recent application tested mechanical fuel injection against racing carbs in a factory developed combination. In both applications, mechanical fuel injection was good for about 5% more horsepower. Fuel pressure is limited in common EFI racing packages. Reduced flow from the venturi’s is a limit in carbs.
This year’s Sacramento AutoRama is a hit. Several new custom cars were on display along with several updated regulars. Various fuel injection setups were displayed. Mechanical fuel injection on autos and boats were my favorite. Check in with the Sacramento Autorama Feb. 17-19. Again, email us at email@example.com if you are attending. We’ll look you up and take pictures.
