4m40 max boost 6 bar max , as i increase the fueling ( namely the boost compensator) the boost presure increases proportionaly as i increase the fuel level. 8 pajero 4m40 that has the wastegate spaced by 3mm and turn the fueling down i can get 0. I'm wondering how much boost people are pulling through there 4M40t. A 'Compensator' is designed to modify the pump in a 3D fashion dependant on this extra flow/pressure the turbo provides. 9 bar? This bleeds boost into the vaccum source supplying the VNT actuator. I've spaced the wastegate about 3-4 mm and blocked the PSV at the back of the manifold. 9 psi) for the 4M40 and 161 kPa (23. Boost Compensators - With turbocharged engines we have vastly different amounts of airflow on boost to what we have off boost. 5 bar and has now been set at 1 bar. Currently the van is running 17psi. That got me thinking though. Any tips on tuning or how hard it is to do yourself or should I send to a diesel specialist? On the 4x4wire forum there was a member who boasted about the high boost pressures he ran on is 2.

What is the max safe psi I can run on stock fueling? Ive been told that it is safe to wind up boost to 11-12psi as the car has a overboost valve on back of exhaust manifold that kicks in at 14psi apparently. I've been considering removing the valve and just adding a manual boost controller to keep me at 14psi in these situations. For what it is worth, my Max Elery manual states that the waste gate actuator should start to move at 96 kPa (13. it doesn't have fuel delivery adjustments. 3 psi) for the 4M41. it doesn't have fuel delivery adjustments I've been considering removing the valve and just adding a manual boost controller to keep me at 14psi in these situations. He had no need to adjust anything to do with the fueling, just the turbo boost which had been boosting to 0.
