Early and late Injector differences

[Jonny944CS]

Following on from a conversation with Mike (A9XXC) at this weekends post classic event:

I found this on Fr Wilks website regarding the difference between the pre/post 85.5 units.

The units are rated at different pressures - could this mean the later rail runs at a lower pressure? Also the resistance and equivalent flow rates are slightly different.

I'm not sure how relevant this is to your 2.7 issue Mike, but it sounds like mixing a late rail with early injector may give slightly different fueling.

Thanks for that - relevant for my 2.5 certainly.

Need to do some checking on the 2.7!

Thanks
