 Subject: 4.7 performance Q
IP: Logged
Message:
To any one who has played with 4.7 mods and have not got the results they have been looking for. I have been wondering why. I was reading Martys site KRC performance and I see a blurb on injectors, saying that if you swap to lincon navigator injectors that the fuel ratio goes to 12.5 at WOT. Maybe the 4.7 is a little lean at full throttle and needs to be richened to realize perforance out of things like exhaust mods. What do you think? A little help here Bernd would be greatly appeciated.

My interest is peaked, what is the stock injector fuel ratio at WOT?

I do not know the fuel ratio at WOT with the stock injectors. The details I have found thus far are sketchy at best thats why I am here asking for help. Hope I am on the right track.

I have played with additional fuel on the 4.7..... it doesn't like it. More fuel just makes the catalytic convertor have to work harder to burn off the excess fuel. That actually hurts performance in the upper rpm ranges since the convertor can't burn the fuel and allow more air thru it at the same time. The 4.7 doesn't need larger injectors unless you have changed something major. Even at max rpms (6000), the injector usage is only 46%.
