Om617 boost controller. There were many variants. As the speed increases, the Flyweights, connected to the Ok, short and simple. It will be operated by a WOT switch on the valve cover linkage to My question is, do I need to reconnect any of the overboost control? I have a boost pressure gauge and an exhaust temperature gauge to monitor the engine. We don't care enough about performance with this car to change any . This kit uses 12AN fittings Your max power isn't increased (much), but the increase in power from idle up to ~4000 RPM is extremely significant. This is a thread for information known about the OM617 and performance predictions we can make based on that information. This is just an FYI post relating to the ability to fuel and boost a stock OM617. This seller provided an exceptionally clear description, with photos and words, of the brake booster for sale. I asked questions before I purchased it, and the seller provided quick and This installation kit eases the install of the HE221 (T25) Holset turbos on a Mercedes om617. It makes the OM617 behave like it's supercharged. With the addition of intake air flow volume at different levels of boost, I can calculate the air/fuel ratio at any point on the fuel curve based on the boost pressure. After that is adjusting the ALDA. The ALDA limits the max available Fuel when there is no boost pressure from the Turbo. Navigating the rabbit Guys, Just out of curiosity, how much power could one squeeze out of the 617 while keeping it relatively reliable? I'm not talking about stripping it down to the block, boring out cylinders, and generally When the Throttle Lever is moved to increase engine speed, the Throttle Tension is increased and the Rack is pushed forward, (increasing fuel). It is purely an emissions device to prevent/minimize the emission of black smoke, Other than the OM617, I'm pretty novice to Merc diesels, and that's not to say I know a whole lot about the OM617. If it's not high enough, crack the valve open a little then do another run and note any difference. If I don't need any of the Start by closing the valve all the way then make a run to determine your boost level. Your max power isn't increased (much), but the increase in power from idle up to ~4000 RPM is extremely significant. I am only making 6 pounds of boost does anyone know of When the control lever is in the idle position, the effect is approximately zero. So, Im running an OM617 from an 81 merc sedan and it has the alda turned up to MAX, and the boost Car is 1983 300CD with 1985 300D OM617 engine. You MUST understand this system to properly tune a 1978 to 1985 turbo diesel for maximum performance! When any part of the overboost protection system fails, your turbo diesel engine can I'm working on an electric valve that will route the actuator air through a manual ball-and-spring boost controller. While I cannot deny that the om617 is extremely reliable, it is still a classic car and not without it's issues. I looked up what was involved to build a MBC and this is a cross post from STD for anyone interested in a high power OM617 and what goes into building one Hello i don't post a great deal here. So it seems like an easy thing to install would be a manual boost controller and then I could fine tune the boost to never go above 12 psi. Just This is a picture of the Agens-bv VNT OM617 turbo kit + with a Dieselmeken 7. 5mm injection pump applied into Bjorn’s Mercedes G during the Super Karpata Trophy 2022 . It makes the OM617 behave I believe the max stock boost is 12 psi. HE200 5cm² - This is the best turbo for a stock pump.
