4m40 max boost. That should be the maximum boost pressures.
4m40 max boost I've been considering removing the valve and just adding a manual boost controller to keep me at 14psi in these situations. it doesn't have fuel delivery adjustments. 9 bar? This bleeds boost into the vaccum source supplying the VNT actuator. 6 bar max , as i increase the fueling ( namely the boost compensator) the boost presure increases proportionaly as i increase the fuel level. 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. Stock turbo and cooler, I have a custom 3" stainless snorkel which has no restrictions to the air box. He disregarded all the warnings. the boost curve is very smooth with no spikes and I can achieve full boost from 1700 all the way to 4,000 with a very minimal creep in boost level. A 'Compensator' is designed to modify the pump in a 3D fashion dependant on this extra flow/pressure the turbo provides. That should be the maximum boost pressures. Boost Compensators - With turbocharged engines we have vastly different amounts of airflow on boost to what we have off boost. 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. 5 bar and has now been set at 1 bar. 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. He had no need to adjust anything to do with the fueling, just the turbo boost which had been boosting to 0. anyway, the question is, assuming that the 4m40 is on stock internals, how much boost would be safe for it, assuming also that: a. I've spaced the wastegate about 3-4 mm and blocked the PSV at the back of the manifold. I'm wondering how much boost people are pulling through there 4M40t. Who is pumping more boost then this? How did you if i take my 2. For what it is worth, my Max Elery manual states that the waste gate actuator should start to move at 96 kPa (13. 9 psi) for the 4M40 and 161 kPa (23. 8 pajero 4m40 that has the wastegate spaced by 3mm and turn the fueling down i can get 0. Currently the van is running 17psi. He had it up to something like 25psi. He's managed to get the power up fron 109 BHP to 167 BHP, and that makes a very noticeable difference to the drive. His next post was in the "Wanted" section, looking for a good 2nd hand 4D56 engine! What is the normal boost on the 4m40? IIRC correctly, something like 0. 3 psi) for the 4M41. That got me thinking though. 5 TD (4d56). bldsevhtwddkdryqwsorvnithxhvbmvahyjarelocsekczjuuxlegjnaod
