Hi
I keep reading about green/red/ FP what does it all mean?>

Green means E85? Im confused

 

 

FP means Forced Performance, which is the manufacturer of these turbochargers.
Forced Performance calls their turbochargers FP Green, FP Red, FP Black, and so on. The names also indicates their level of "class" in regards of performance output or the "user's HP goal"
To simplify, the tier for the turbochargers are as followed from lowest power to highest power;

FP 71HTA
FP Green
FP Red
FP Black
FP Zero/Zephyr

Turbochargers has nothing to do with E85, that's all in your fuel pump, fuel injectors, and MAP
