Injector size

Post by deleyev »

hello,

i changed my 6 injector.
now I have 4 blue and 2 yellow injector.
What is the injector scalling ?
Normally If I use the OEM fuel pressure ( 3.5bar) The yellow inj have 522cc/min and the blue have 626cc/min.
Can i put this value or i need to put the flow rate at 3bar?

Thank you for your reply

Wow very different values than I understood, I was under the impression red was 290cc, yellow was 380cc, and blue were 420cc. However I am in the US, I'm not sure if the units are different elsewhere. I also plan to upgrade to a 255lph @40psi Deitchwerks DW200 fuel pump in the future and I am curious how I should alter the tune?
