Sup guys.
Just started my engine after I finish setting up all the fuel lines, SMFU, fuel guages.. and I JUST REPLACED the Walbro 190 to the 255HP! Nice..but ALOT LOUDER! Is there a way I can make it quieter?

Anyway... I want to know if what I see is correct.
Currently, my fuel pressure:
static: 63PSI
idle: 55PSI

are the number right for stock injectors and NO TURBO in?

Also I do'nt konw why, but when I step on the gas pedal (not WOT but up to 3K RPM) the pressure stay at 55PSI... HOW COME? (I have the vaccum connected then)

Shouldn't it go up as I step on the gas?

THanks guys.

someone confirm this!
but I believe that stock fuel pressures are around 45 psi. if you are installing the turbo soon, then keep it at the pressure that it is at now.

your pressure will not rise until the sfmu sees boost, and it will rise proportionately to the amount of boost it gets.

Yeah...45Lbs

Thanks alot..
so idle should be 45PSI, how bout static pressure?
Thanks.
GIL

THanks!
So for my current PSI
Static: 63psi
Idle: 55psi..

Should I leave me?
I will put the turbo on in 1 weeks running 5PSI
and my 330cc injectors..(I want to get them)

So should I change my PSI?
GIl

you've got a couple of minutes don't you?

IMO there is no reason to be cruising around with that pressure if you don't have to. anyways with 330 injectors you will have to lower that pressure.

OK..thanks.
So what should my static PSI should be?
Thanks
Gil

I'm pretty sure that it would be 50lbs. try it out and see what your idle pressure ends up at.
