[White97eclipse]

Im about to get my bottom end built so im going to be turning up the boost! I cant remember what the equation was for lbs-cc... so what boost level would i be good to go to with the 30lb injectors?

30lbs 300cc. i would prob say around 10 12- psi at 80% pressure on the injectors .

the lbs to cc equation is 10.5 x lbs = cc. as for how many psi can you run? that all depends on the turbo. not all turbo's are going to flow the same amount of air at the same psi, which means different turbos will have different fuel needs for the same psi. you need to do an equations with CFM's in it.

no, if you do the equation, they would be 315cc. and im not sure how you just made that psi guess without even know what turbo he's running. he could be running a little RC car turbo with 1/4" piping, running 10-12 psi on that will def. not need 30lbs injectors.

30lb inj's
or
312cc's

EACH inj is good for about 50 hp EACH at 80% duty cycle
