17PSI is my maximum, on track I only have 11PSI.
I don't have good interior pictures for moment.
6x750cc injectors are enought for 650whp, on my old Civic I had 525whp with 4x750cc.The main problem is to keep the fuel pressure in the fuel rail.
If I want to increase my power is to add a inline bosch fuel pump, not the injectors.
Did you add another fuel pump, upgrade your injectors to 1000cc or do anything to your existing fuel pump to get 700rwhp?
I have walbro 255lph fuel pump and 750cc RC injectors and I am running out of fuel at 550rwhp.
