highest fuel pressure what is the highest you can regulate fuel pressure under boost,. twin walbros and 60 lbs injectors. if i referance the regulater how high can you go. 80psi, 85psi? thanks

More pressure makes up for a lack of injector, but reduces pump output.
I generally recommend that starting w/ 58psi, boost reference to a max of 75psi.
Above this pressure or say 850rwhp, I would consider bigger injectors at lower pressure for best results. With large low impedance injectors, I would start with 43psi base pressure for best results.

I've run 5 bar base pressure with twin walbros and 60lb injectors with no problems. Have not tried higher.

Also remember that the more pressure the pump(s) produce, the higher the temperature of the fuel and pump(s) will get. Both are not good as the high fuel temps can lead to detonation and high pump(s) temps can result in shortened life.
