Hi mate. What you need is a set of 'whites' or 'blues'.
The white injectors will flow at 350ccm using a 3 bar regulator.
Blues will flow the same rate using a 3 bar regulator BUT...using a 3.8 bar regulator will allow the blues to flow 395ccm.
Hope that helps your choice.

Hello Joe,

Unless you have a very high power 940 you won't need more than 350cc injectors.

In point of fact, the standard injectors for the turbo redblocks run at 300cc/min and that's good for 185bhp at the flywheel (at 100% maximum duty cycle and 3 bar fuel pressure) - not ideal as there is no room for hp increase at a later date.

350cc/min injectors run at the ideal 80% max duty cycle, and 3 bar fuel press are good for 215 bhp, and at 100% = 270 horse.

So, basically, over 350cc is just a waste of time, money and effort unless you're making, plan to make over 270 bhp; and you'll create problems that didn't exist to boot!

BTW, Green injectors run at 465cc/min @ 3.8 bar fuel pressure (over 3.5 is not ideal as it puts undue strain on the standard type fuelling system in general) and are good for 285 horse at the 80% max duty cycle - with up to 355 at 100%

Cheers,

T
