Cars The Cummins 12V turbodiesel engine that was available in through Dodge Ram three-quarter-ton and one-ton trucks has seen wide use among performance enthusiasts. The 12V is a strong engine that is capable of withstanding substantial horsepower and torque increases over stock. One way to increase the power is to raise the boost pressure. Boost is the intake air pressure as supplied by the turbocharger, and more boost equals more power. The factory utilized a wastegate to limit boost to 22 psi lbs per square inch , but it is a simple matter to block the wastegate vacuum line to achieve up to 40 psi boost. Moderately ChallengingInstructions Things You’ll Need Cars Vehicles have a multitude of different options that can be placed in an engine to boost performance, including a turbocharger. The turbocharger is an accessory that houses many different sub-assemblies, like the wastegate solenoid.
Boost Control Systems Explained….. Part 2
Completely modular, it can be installed as a vent-to-atmosphere BOV or re-circulating diverter valve. This universal package can be outfitted to most any application utilizing our interchangeable mounting flange system. By design, it is a pull-type valve only. It operates in a normally open condition. This means that it is designed to remain open under vacuum conditions. For maximum performance and reliability, it is recommended to install the Synchronic BOV in a re-circulated configuration with the discharge between the MAF sensor and turbocharger inlet.
Feb 21, · More importantly how was the vacuum line that ran to the gate? I have seen people pop a vacuum line off a wastegate, overboost, and blow their motor. Same with goes for the ebay Tial .

Power Adder Tech: Properly Sizing Blowoff Valves And Wastegates
The great thing about the Hallman Evolution Boost Controller kit is that you can adjust your boost from inside the car. This is really great for setting your initial boost for the very first time. Now you can set your boost within a minute or two and never stop the car.
A turbo system’s wastegate is like a sentry constantly pacing the boundaries, keeping the flow of boost in check. It prevents the turbo from overboosting by bleeding off exhaust gases, or more.
I just completed adjusting the wastegate, and wanted to share my technique for others who may be looking to do the same thing. While I did find the info I needed here, it was literally hours of searching to find all the pieces of the puzzle for me to complete this. I am hoping this post will put all the info in 1 place to make it easier for all.
The wastegate is a mechanical safety designed to limit the amount of boost from your turbo. Sure, boost is great – after all it’s what the turbo is designed to create – but too much boost can be detrimental to your engine. It is generally stated that a stock OM can safely handle only up to about 15 psi of boost – and only for short periods of time at this pressure. The stock wategates were set at about This essentially stops the turbo from being able to deliver any more than The reason for checking and adjusting the wastegate is that over time, the spring which keeps the wastegate flap closed gets weak.
When new, the spring had enough tension to keep the wastegate closed until the pressure reached about As it ages and gets weak, it begins to open at lower pressures. This dumps the precious boost your turbo is making right out the tailpipe.

I tried adjusting the valve some today and the first adjustment it shakily and struggled to 12psi, the second adjustment it held solid on 12psi but struggled even more. I removed the BC and ran the wastegate to the turbo and it spiked to 9, but held 8 steady no struggling. I then ran the wastegate with no vacuum source and it wanted to boost high and happy.
Ive checked the BC out and its clean as can be, the spring isnt broke, the ball is on the bottom of the spring, the wastegate vacuum line was on the side of the valve, and the engine source was on the bottom. The source came from a line going to the tree, the stinger dual pison bov also is coming from the wall, and I verified the boost readings from an Autometer cobalt gauge which is teed off the line that is hooked to the bov.

Here are several potential causes of limp mode on a TDI. The turbo is a vacuum modulated device. When more vacuum is placed on the actuator, the turbo develops more boost. By modulating the amount of vacuum the turbo actuator gets, the ECU is able to control boost pressure. When the ECU cannot control boost pressure, the actual boost deviates from the specified boost.
When this occurs, the ECU reduces fueling and requested boost to ensure that the turbo is not damaged. We will now cover the potential causes of this situation. Some of these procedures may exceed your level of mechanical competency, and should be left to an expert with a strong TDI background. Cause 1 boost leaks.
A boost leak is a hole in the intake track between the intake manifold and the compressor outlet of the turbo. This portion of the intake is under pressure when the engine is loaded. If there is a hole in this part of the intake track, boost pressure will leak out, and the MAP sensor boost sensor that sends a signal to the ECU reporting boost will not be able to accurately report on the turbo’s behavior.
Not making full boost
In Part 1, we describe the basics on how your boost control system works and the components involved. Some of the diagrams in Part 1 were common items found on stock turbocharged engines, and some only found on aftermarket turbo systems. In both setups, its possible get more boost from your turbo, than the wastegate spring pressure.
Mar 15, · vacuum hose and external wastegate Posted by gsx20g, Mar 13, Mar 13, #1. gsx20g Proven but I do know that the top port of the wastegate on a Tial is designed to keep the wastegate closed on an electronic setup. Yes, but if I had a dual solenoid boost controller, I’d hook the top port up to fully maximize spool up.

Sep 05, · For the Tial Wastegate, hook up the bottom port to a boost controller (leave the top port open). On the other end of the boost controller connect it to a boost source (either a nipple on the turbo’s compressor and a nipple on the J-pipe).
Resurc vs atmospheric Contributed by: These valves save our forced induction components in a way that most users may over look. Other terms you may hear or read about that are essentially the same thing to Blow Off Valve, are recirc valves, diverter valve, bypass valves, or the abbreviation BOV. Why we have blow off valves? These valves open whenever there is enough boost pressure in the intake pipes, and vacuum from the intake manifold.
Essentially, these valves operate every time the throttle is opening enough to create boost pressure, and then backed off to create vacuum. When this valve opens it releases the pressurized air in the intake piping either back to the turbo intake piping or vents it to the atmosphere. The reason this is important is because if that pressurized air is not allowed to escape once the throttle butterfly closes, then the air will apply pressure on the turbo or superchargers compressor wheel putting un-wanted stress on it.
While this stress is very small, over time it can cause added wear to the bearings and cause the unit to fail prematurely. Another great benefit of a BOV, other than adding longevity and reliability to your set-up, is that it can help maintain turbine speeds in-between shifts adding a performance enhancement as well to the vehicle.
There are not many modifications one can do to an engine that can give them reliability and POWER, so a BOV should be an essential component on your list if running a turbocharger or centrifugal blower. The reason for this is that the MAF has already accounted for the air that is in the intake manifold, and if it was allowed to escape to the atmosphere, the car would run overly rich due to the fact that the ECU still believes that the air is in the intake tract.
A bonus to running a re-circulated BOV is that the air being re-circulated can be brought back into the turbochargers intake pipe at a location and angle so that the air pressure is forced directly onto the compressor wheel. This will aid even more in helping to keep the turbo spooled up and running in-between shifts, or times when you are quickly on and off the gas pedal.
