Upgraded HPFP, LPFP and Stock Injectors
« on: November 30, 2019, 07:19:49 PM »
Does anyone know the flow rate of the stock injectors?  And does anyone really know if the stock injectors are adequate in keeping up with the additional fuel pressure of the XDI35, XDI60 and DW LPFP?

The stock fuel pumps are a bit under sized so upgrading them you will still see increases.  But to get the most out of the engine you will want to upgrade injectors as well

XDI is releasing injectors as well soon... not sure what they are gonna look like..

Thus far the stock injectors are pretty stout little bastards.

IMHO,

I don't think the injectors are a problem.  From what I have seen they flow more then enough for our power demands.  Pretty sure the engine will give up before you max the injectors completely.  Matt says a drop in fuel pressure is what causes the injectors to stick open. 

If you have the upgraded HPFP and in tank FP you should be fine. 

Now if you are replacing injectors for peace of mind, that is a different matter.

Yeah I was just kicking around the idea of replacing them.  I then wondered if it was actually pushing the stock injectors harder with an upgraded HPFP.  No evidence to say it is but also not enough data/results/reviews of ppl using the upgraded DW injectors.  I think I'll keep my interest on pause until I see what XDI comes up with.

In the meantime would throw in some Chevron with techron fuel injection cleaner inside the tank @ every oil change for good measures.
BG-44K cleaner also works well for the GDI applications..

$6.99 with coupon applied..

You should be able to see injector duty cycle and see if your pushing at 80 or more this will tell if its worth changing or not
