19lb or 24lb Injectors

[Jeff Chambers]

Just like a carburetor, the engine will only use what it needs. I'd rather run an injector at 60% duty cycle safely then push it to 95% or higher duty cycle. If the MAF is calibrated properly (or custom tune done), then you'll get the same fuel delivery for a given amount of airflow whether its 19#, 30#, or 42# injectors....assuming you haven't pegged the meter or saturated the injectors. As a matter of fact, if he's planning on a supercharger/turbo on down the line, why not go straight to 42# injectors with a Lightning 90mm MAF now and save getting new later? Buyfordracing.com has a 42#/90mm combo going right now for $349 to your door. Hard to pass up.
