I just had my injectors cleaned and they flowed 490cc/min@ 3 bar, official flow is 503.4cc/min.
490cc/min on a cossie = 490/5 = 98 X 4 = 392, making each bar worth 130, now add boost to 32 psi, oddly enough Fast Ford in September 05, page 56, rated the greys from 450-500, that was written by Alastair Maine.
