supercharger fmu question help

[mat82284]

i have the whole kit but the fmu i bought it from someone and he didnt send the fmu its on the way now but can i install this without it or will it mess up my car???

ya you have to have it unless you run a FPR i believe?

 

[mat82284]

whats fpr???

Fuel Pressure Regulator.

 

[mat82284]

i have a stock fuel pressure regulator but thats all i know. i have a 92 mustang 19lb injectors

 

[88stangmangt]

ya but that is non-adjustable and isnt worth $hit. you will be fine with the FMU.

Dont run it without the FMU, wait till it comes.

 

[mat82284]

i guess ill wait but if i installed it can i use the stock belt to run it with out running the supercharger i seen this pic

 

[88stangmangt]

ya that would work some people do that for winter or when it is hott.

 

[mat82284]

if i just got fuel injectors how do i know what size to get instead of useing fmu i would rather upgrade anyways should i get 30lb or more??? im going to run it at 6psi for now but may up to 9 later later on.

If you are using stock long block than the 30# injectors will be good up to 9 psi.
