vq35tt with cjm pump and cosworth rails id 1000cc at 20psi what should my psi be at?


Should i run 50psi at idle? and let it go to 70psi when in boost?

 

What is your base pressure set at?

 

I am just asking what ppl run?

 

my aps extream kit did 55 psi

 

...

 

Mine is about 42 PSI

 

I recommend 43.5psi base with no vacuum/boost, which is common/standard 3bar base fuel pressure. This means fuel pres will be in the 30s at idle, and 63.5psi with 20psi boost.

There are a few occasions where I will be intentionally have it higher/lower (such as running high fuel pres on a setup with plenty of fuel volume/pump availability but small injectors), but for a normal setup 43.5psi base fuel pres.

 

I run mine around 40psi also.

 

I'm running a built motor with JWT twins a Walbro 255 and DW 880's with CJM stg 1 FRS and i'm set at about 40-41 psi at idle...

 

what hal said. this is what i run on all my cars. especially if you input "injector flow" in whatever ems you have, you set the pressure at what the flow of your injectors is rated at. if not your injector flow will be incorrect.
jacking up the pressure is (usually) just a band aid. The right components with enough flow won't have this issue.. these aren't honda civics, do it right.

 

i have the t 60-1 kit, 8psi, 380cc injects, stock internals, if i were to get a F.P.R, what should my pressure be set at??
thanks.
