A  Boost controller helps in regulating the amount of air pressure applied to the intake manifold of an engine.

The mechanism of boost controlling is made to best of use by modern turbo-charged engines. In these turbocharged vehicles (equipped with digital displays and modern engine management systems), the boost control mechanism employs electronic control to help in easy alteration of the boost pressure.

Manual boost controllers are, however, widely popular across the vehicle owners and come as a superior cost-effective option.

Boost control mechanism

It all starts from waste gate actuator. Attached with a boost control solenoid, waste gate actuator is the point where the boost pressure is sensed first. Evidently, if you alter the pressure on the waste gate actuator, you can effectively control the turbocharger’s boost pressure over a range of values; and program the exact boost profile required by the engine. The idea leads to a boost control Solenoid Valve, placed in line along with the boost sensing hose to the waste gate actuator. The boost control solenoid valve pulses at a controlled frequency, and thereby effectively controlling the bleeding of boost pressure from the actuator.

The higher is the pulsing frequency, the greater is the amount of boost pressure that is bled. The waste gate actuator senses a boost pressure that is lower than the actual boost pressure. And in doing so, it allows for greater boost pressure before the waste gate opens the swing valve.

What to choose – manual or electronic

In the presence of both manual as well as electronic boost controllers, it is up to you to decide which one to go for. You should get the one that fits to your budget and requires an easy installation process.

Now, be it a manual boost controller or one electronically operative; to let your vehicle thrust ahead, all you need is to get is fitted with a boost controller. And if you’re a little confused about what to go about, try surfing internet.

Your little concern towards the boost controller of your car can let you benefit from its enhanced performance.

Normally they are press fitted to the housing
Difficult to remove with out damaging

Scanned my 1990 Mazda RX-7 (Non-turbo) for codes. The code was for my split air Solenoid Valve. What is that, and does it effect my mpg any?

Yes if this component malfunctions it will increase fuel consumption.

I need about 10 battery operated solenoid that had the coil and valve already built in together. I’ve only been able to find the ones that are powered by electricity. I appreciate your help

Here’s one that uses 12vdc @ 250ma but requires water to be under pressure to operate the valve (called "pilot" operated) and won’t work with gravity fed water.

If you’re using a 12v marine or automotive battery this would be the choice if the water pressure is around 50psi. Is this for a Irrigation system?
Asco is a big name brand that carries huge selection of Solenoid ValvValves with coil options that match what power you are using, but not the cheapest.

ok so i need to pass the north carolina emissions and well i failed the first time because of my secondary air injection valve n112. I am having a hell of a time even finding the part, I found it through vw but they want like 160 something plus labor so I’m trying to find out how to do it myself and if anyone knows a good place to find the part cheaper, I would be extreamly thankful.

Go to vwvortex
there are tons of people there that can tell you everything about anything you need to know about any VW… that would be your best bet then askin yahoo answers (its all opinionated hear)

i have a 96 Nissan maxima and wanted to know if egrc Solenoid Valve is the same as the "EGR Valve"?
well i was going to take it out and clean it myself…

Nope.

I own a 2001 nissian pathfinder and my service engine light came on and the code read: p11 31 swirl control Solenoid Valve function. Does anyone know what that does? How much it costs? Or what that means? PLEASE HELP ME PEOPLE!! Thank you!

The Nissan KA engine has butterflies in the intake manifold on each cylinder intake port which induces swirl in the combustion chamber for better vaporization of the fuel/air mixture and better combustion. The butterflies are on a shaft running through the intake manifold and on the end of the manifold there is a lever (aka swirl control valve) controlling the shaft which is activated by a solenoid which is controlled by the ECM. I expect either the shaft is seized and the lever is not functioning or the SCV solenoid controlling the lever is not functioning.

Edit note: I just discovered that the 2001 Pathfinder has a VQ series V6 engine and I don’t know if it has swirl inducing butterflies in the intake manifold as the 4 cylinder KA engines do but I suppose it does if you are getting that diagnostic trouble code.

What year and model vehicle please?

Pneumatic Solenoid Valve, need to get the cover off to make the wires longer.

Depends on the brand. Asco ValvValves have a clip that slides off the top of the coil. Skinner valves have a retainer nut on the top of the coil. The coil slips onto the plunger chamber or tube and the retainer holds it and the cover in place.

Rain Bird produces the best of the best in irrigation control systems. The Rain Bird ESP-4TM 4 Station Indoor controller combines the best features of the ESP Modular controllers with a slim, unobtrusive casing to make a perfect indoor control panel for home landscape irrigation systems. “ESP” means “Extra Simple Programming” and programming this controller is just that. These models are best for home and small business landscapes without more than four zones, and for people who do not plan to expand their irrigation needs. In order to add more stations to this irrigation controller, you would have to install different controllers, or upgrade to a controller with more stations. The ESP-4TM models come with either four, six or eight stations, but they are not modular.
Dual Programming Provides Plant Health
This feature of the Rain Bird ESP-4TM indoor controller allows homeowners to set two completely different programs for use in various areas of the landscape. Areas of sun and shade can be split up, as can lawn areas and flower beds. The two different programs can be customized to meet the watering needs of various micro-climates within your yard. The water budget feature lets the user change watering schedules in times of extreme drought or heavy rains to save water and money, while ensuring plant health. Each station can accommodate one 24VAC, 7VA Solenoid Valve, in addition to a master valve for the system.
So Simple a Homeowner could Operate It
This Rain Bird irrigation control is perfect for landscape installers because it is so easy to teach a homeowner with no previous irrigation experience how to use it. It has a large, easy to read LCD screen and an intuitive programming interface. The battery backup helps maintain the time, date and programs in the event of a power outage so that the entire system does not have to be re-programmed. The controller also has advanced surge protection to keep damage from lightening strikes or man-induced surges from ruining the controller. This keeps costs down by limiting surge transfer from control box to individual valve controllers.
Lots of Features without Complication
The Rain Bird ESP-4TM indoor controller has all of the features of a professional controller with the precision of Rain Bird parts built for much larger systems. The controller has a three year warranty, a five year lithium battery, dual programming capability, advanced surge protection, day of the week watering programming, self-prompting display, manual start/stop capability and more. Along the spectrum of residential/commercial irrigation controllers, this controller falls somewhere in the middle. It is easy enough for a homeowner to use, yet does benefit from attention of a landscape contractor. The automated programming features make it an ideal controller for landscape technicians that oversee several different irrigation systems. Lastly, the fact that the homeowner can control the irrigation system from the comfort of the indoors means the system is more likely to be used, maintained and accessible.
