Want this question answered?
50psi....... loves it
i run mine at 20psi with an intercooler, stock it 11.5psi. runs fine on 20psi completely stock apart from 2.5" exhaust
Boost is positive pressure in the manifold, so you only see boost when you give the gas pedal heavy load. The best way to check the boost pressure is to connect a vacuum hose to a boost gauge. This will tell you the exact boost pressure when you are in wide open throttle.
I have just fitted a Terrano 3.0 diesel into my Double cab and dont have much boost - max 0.2bar. If I override the system and suck on the wastegate servo then boost increases up to 1.1 bar and goes well. Seems like the wastegate is normally open and needs the extra vacuum to close it and provide the boost needed. I havent done any more development , but need to find out if I can get that vacuum needed from the inlet or if the control system is faulty. Maybe yours is doing the same thing. Drew
boost pressure, as you call it, will not show on gauge,if you have one, while engine is at idle the turbo pressure does not boost but runs all the time according to the revs of engine
Boost pressure is the amount of pressure above normal atmospheric pressure the turbo/supercharger is producing. Can be expressed in PSI (US used) or BAR (mainly outside the US). BAR = (boost pressure) * 14.7 (atmospheric pressure) / 14.7 (atmospheric pressure), an example 8psi of boost equals: 14.7+8/14.7 = 1.54bar
it has a timing chain

A boost gauge in an internal combustion engine has the role of a pressure gauge. The gauge indicates the manifold's air pressure or a turbocharger or supercharger's boost pressure.
It has neither. The Terrano 2004 diesel uses a gear mechanism.
boost is pressure. units of pressure is pounds per square inch(psi), atmospheres (bar), and kilo pascals (kpa)
