How much hp/ stock injectors?
How much hp can the stock, 19#, injectors support on the 4.6L V8?
I am starting research for my turbo build and would like to fab everything up and run extremely low boost on the stock fuel system and upgrade the fuel system once everything is up and running.

Well, this good site list the 19# are good to 310 hp max. with a NA motor. There is some good info in the FRPP catalog on how to size injectors based on hp and if NA or FI. Don't have the formula handy.

Awesome, thank you for that link. My question stems from the idea of putting a rear mount turbo on my F150. I want to start off on a very low budget, which is why I dont want to upgrade the fuel system yet. I only plan on running 4-5 psi with a 10:1 fmu.
Thanks

Here is another site with all kinds of calculators in it. Not sure of the HP you're looking at but throw that figure in and might see you will need bigger injectors.
