can anyone name what injectors these are? Bought a used s/c and just trying to see what i have exactly...

 

The pic looks messed up on my computer but it doesnt look as if the fuel rail has been modified so I would venture to say 42#'ers

 

Find the markings / serial numbers.

 

They look like 39# cobra "blue giant" injectors. Do a search on that, the pics look just like what you have there.

 

They have the right color for being 39# Cobras and the correct connector(USCAR / EV-6) also. BTW, Ford Motorsports rates their injectors at 39.15 fuel pressure so they flow about 50lbs/hr at our 58 PSI. If you are putting them into a nbs Chevy truck you will need to get some USCAR pigtails.

 

why would you take out the 42# injectors that come with the maggie for 39#'ers?

 

The Cobra injectors and the 42#'s flow about the same at the same fuel pressure.
But if you have the Marine injectors already too I would use those instead because
they don't need any adapters/pigtails and no need to raise the fuel rail either. Plus
the dead times from stock to the OEM Marine 42's is almost identical whereas the
Cobra's might need some adjusting for "Battery offset" and "Min/Max pulswidth" etc.
It would some you some money and you could sell the Cobra's to boot.

 

correct.....used in the flex fuel trucks.

what year, make, model, and motor do you have?
