Are they rated based on max HP or max lbs. of boost? I know that the stock Honda fuel rail can handle 300 hp. Does anyone know how much boost I can run on stock injectors with the blue box and a 255 walbro intank? oh, and a b&m fpr.

 

bump

 

anyone?

 

they are 240cc injectors.

go to http://rceng.com
and in their tech section they have a calculator

 

theres alot of answer for this question.... with stock injector and a fmu...around 6-8 psi is safe for it and thats around 150-160hp??

 

10psi max .
i think the 240cc top out of efficencey at like 220whp?
