ok.. so i hooked my fmu back up and i figured out how to reduce belt slippage.. so now im getting 14-15psi... my 370cc's and sard fpr are on their way and I was wondering what fuel pressure i should adjust it to at idle? also as for the fmu do I have to change anything on it? thx in advance.

 

I've read that the base should be at 34 psi

 

I believe BlackCat is correct. My Fuel Pressure gauge does read 34psi at startup/idle.


What size disc do you currently have in the FMU??

 

do u have a intank fuel pump??

 

Kinda OT, but for only 7psi's on 3.6" pulley, what size disc should we install? Heard 8:1 is stock from the V2 kit, but tune's a bit rich.

Conceptually, I thought the larger the disc size, more fuel pressure is produced by the fmu on boost, then afr would get richer. Am I right? If so, then for my intended 7psi, can I safely use a 6:1 disc? Thanks.
