I just put in 24lb ford racing injectors w/ a holly fuel pressure regulator in this morning. I was wondering what is the best fuel pressure to run these injectors at? Thanks for your input =)

Need way more specifics on engine mods before anyone can "guesstimate".

 

its a stock remanufactured 350TPI. All i have on it are those injectors and 3" exhaust. Hooker 2055's, super comp catback, strait pipe cat.

 

The 350 TPI's used 22 LB. injectors stock. I'm thinking they were set at around 43 PSI from the factory. I would start around there, and adjust it accordingly. If you don't have a local drag strip around where you can test and tune, you may have to go with the 'ol "seat of the pants" method. My guess would be around 47 PSI, but that's only a guess.

 

It depends if you are running MAF or SD. If MAF, by all means lower it until the injectors flow roughly 22lb/hr. If SD, you have some VE increasing mods which will need more fuel, but I still would say very close to 22lb/hr. The stock PE fueling is overly rich as it is, no sense in richening it up anymore.
