Can anyone state a maximum boost pressure for TD-6 4.2 iTD Patrol and at what rpm this should be achieved?
Thanks

Wayne, it depends a bit how much performance you want. If you are looking for longevity of the engine 13-15 psi seems maximum boost, pre-intercooler, but if you want maximum performance I have seen competition boost up to 25 psi.
The standard of the intercooler may be in question too, at higher boost pressures. The OE one is small to cool that much additional air.
Have you looked at
Outer Limits?

Hard one to answer really and I suspect not an easy one to find out. The discovery may be made when something lets go.
Looking for more Boost???
Looking at my mates patrol the other day, the Turbo set up on it don’t look like the most efficient thing around, I.E Smallish cooler and Small diameter piping= Hot Air charge and restrictive air flow. Running High Boost and high Air temps will shorten the life of the motor.
If you can sort Plumbing and Cooling out then you will gain more power wile keeping the same boost level. I,E You can pick up 12RWKW in a Turbo Falcon just by installing a bigger Intercooler.
The RPM that you make Max boost at will depend on what Turbo you are running and how much boost you are trying to make.

They are very safe with 15-16 psi in standard intercooler trim, with a proper 3" dump pipe [not the cast "supposed" 3" units] and 3" mandrel exhaust, and turbo mods from MTQ, which all help push heat out the exhaust, and a retimed pump and dyno tune, with pyro fitted right after turbo to keep an eye on things normally means around 125 rw kw and 480 ish T N at the
wheels.
Fuel economy usually gets better by around 2 lt per 100km, unless using the extra power.

Thanks mate,
I have a stage 2 upgrade, with a 3" full system.
I was looking at changing the intercooling pipework ASAP.
Any ideas as to what cooler i should replace it with?
