How to Install a Manual raise Controller Without Blowing Up Your Engine
Prior to installing any manual raise controller, it is important to have already additional a high flowing exhaust and an aftermarket air intake/ air filter. This will ensure the car is able to breath, and will allow the turbo to spool easier.
It is imperative to have installed an aftermarket raise gauge. Most stock raise gauges are not accurate, already at stock raise levels, and lose further accuracy once stock raise is increased. Without an aftermarket raise gauge you risk damage to the engine from overboosting.
How It Works:
The wastegate actuator determines your stock raise levels. The raise controller interrupts the pressure line that runs into the wastegate actuator, allowing you to increase raise over stock levels.
Find your wastegate actuator which is usually attached to the turbo, unless you are using an external wastegate. The wastegate actuator will have a vacuum line port that runs to a raise source. The raise source is usually either the turbo’s compressor housing, the intercooler pipes, or the intake manifold. This vacuum line is where the manual raise controller will be installed. If there is a T fitting in the vacuum line between the raise source and the wastegate actuator, it will have a separate vacuum line that runs to the raise control solenoid. If you have the T fitting, remove the line that runs to the solenoid, but leave the solenoid plugged in.
The barb on the raise controller that connects to the wastegate actuator will have a small hole drilled into it. It is important to leave this hole open, and never switch the wastegate barb and the raise barb.
raise controllers typically come with approximately 3 feet of vacuum line that you can cut into 2 pieces of desired lengths. The first piece will connect from the raise barb on the controller to your raise source. The second piece will connect from the wastegate barb on the controller to the wastegate vacuum port. Tip: if you have difficulty sliding the vacuum lines onto the barbs, use a little bit of oil to lube the barbs. Block off any open raise supplies with vacuum caps and use cable ties to obtain all vacuum line connections. We recommend using Premium Fuel with all turbo cars, especially once you have increased your stock raise.
Now that the raise controller is installed, it’s time to test the car. We recommend leaving the adjustment knob exactly where it was when you received and installed your MBC when you begin testing. Turning the adjustment knob clockwise increases raise, turning the adjustment knob counterclockwise decreases raise. This step is very important to keep an eye on your raise gauge to make sure you do not overboost and cause any damage to your motor.
excursion your car in an secluded area where you will be able to stop and go several times without interfering with traffic. Slowly press the gas and watch your raise gauge climb. If the raise gauge does not hit your target, increase the raise. If the raise begins to go beyond your target, decline the raise. Repeat the steps as necessary. It typically takes between 5 to 10 adjustments to get the raise exactly on your target. We recommend starting by adjusting the raise knob in 1/2 turn increments, and as you get close to your target you may need to make smaller adjustments. Never adjust more than 1/2 a turn at a time.
Each car has a maximum safe raise level, depending on upgrades to the means and the characteristics of the fuel system, specifically how much fuel your pump and injectors can provide. It is important to research and know what the maximum raise level your specific car can safely run.
This guide serves as a basic starting point for manual raise controller installation. If you have an external wastegate or twin turbo means, the installation technique may vary slightly.
