Fuel injector & max duty cycle
Hi everybody
I just joined this forum. Could anyone tell me what is the max duty cycle of a fuel injector? What is the max duty cycle of the fuel injectors of my Evo IV 1996 (Japan local version)?
If I boost to 1.3 bar, should I change the fuel injectors?
Thank you!

Hi
On Evo 5/6/7/8, the injectors are 560cc/min, on the 4 I think they are a little smaller, 540 or 520, but I'm not sure.
Maximum duty cycle is obviously 100%, but maximum recommended is 80%.
At 1.3 bars, you are still below 80% on 560s. They are ok up to about 1.5 bars with standard fuel pressure.
