How much hp can 22lb injectors withstand? I have many upgrades that I am putting on and would like to know if the sock injectors out of my will be able to handle them.

-355
-AFR 180cc heads
-1.5 roller rockers
-FIRST tpi intake
-Hooker 2055 headers
-adjustable fuel regulator
-LT4 hotcam 218/228 duration

22lb injectors?
or should I upgrade to 28-30lb injectors?

 

Will need to know what hp your looking at. 22lb are good to about 300hp. You have an AFR so if you bump the psi at the rail to 58 they will flow 25lb but you might not to go that route. Bosch injectors are good up to and above 6/Bar. 24's will handle about 350hp

 

well from what I've seen on other builds with similar upgrades I should be pushing round 390hp. so I should definitely bump it up but would I need to get something other than just injectors to make it work? I think that I'm going to get 30lb injectors
