Does anyone have a graph of various fuel injectors and what they flow at various fuel pressures(Bar)? I put in some 19lbs fuel injectors in my car, and with the stock 3 bar FRP, it runs super rich. So I'm wondering if it is safe to throw in a 2.5 Bar FPR? I remember seeing a flow chart of the injectors, but I can't find it now...

try this:
Very useful chart. -
19# injectors are way to big for that engine unless you've made major changes in the mass flow through the engine (read FI). And unless you'd done some serious engine mods (head porting and cams and a free flow exhaust) there's no performance advantage to injectors with a greater flow rate that stock. Even then, 17# injectors would be more than enough.
Rather than trying to fix a bad choice by diddling with fuel pressure (which will have an adverse affect on atomization), you'd be better off to revert to stock injectors.The car makes it possible, but the driver makes it happen.

oh wonderful. well I only replaced the fuel injectors becasue the ones in there fell apart and were complete garbage. So I guess I should probably buy some smaller injectors?sigpicComment

I thought you could run 19# injectors in an m42 without a major mpg changeComment
