If I am going to be running 475~500 HP what should I do for upgrading my stock fuel system? Will just injectors be good enough? If so; 50's 55's or 60's and where to get them?

 

sal can get the 60s for a good price, i hear injector dude has good deals as well

 

For the level of HP you are planning on running, here is what I recomend.
50# injectors- easiest to tune, and best idle quality
1997 F150 fuel rail
adjustable fuel pressure regulator
pair of 255 fuel pumps

This is what I am running on my truck
any of the tuners can set you up with this setup.

 

With the proper tune up you can have the same idle and driveability quality with the 50's or 55's.

As far as the 60's they can also have these qualities, but they do require a little more tuning...currenty this takes custom tuning d0 to the fact that very few tuners have be using them.

 

At this point do you think that just a set of 50# injectors would work?

 

Well, yes and no! You need to do the 255lph pumps before anything! That will do for you up to about 460RWHP....then if you plan on having more then go with the 55# injectors!!!

 

Go with the injector that your tuner suggests. Some tuners perfer the 55's and some perfer the 50's. I know JLP perfers the 50's. JDM and PSP go with the 55 and 60's. You want to go with the injector your tuner is most comfortable with.
