Why Choose a Genuine MAC Valve?
Genuine MAC solenoids are the gold standard for performance tuning. Trusted by tuners around the world, they deliver consistent, reliable performance even under the most demanding conditions.
Pro Tip: ECU Tuning is required after installation to realise the benefits of your boost control solenoid.
Be aware of counterfeits, this the GENUINE article.
PLUMBING:
The diagram below shows suggested plumbing up for both single port wastegates (internal wastegate) and for dual port wastegates (external wastegate eg Tial, Turbosmart, etc). Both plumbing examples are fail-safe so that energizing the solenoid will increase boost. If the valve loses power, boost will drop to the minimum mechanically set pressure.
ELECTRICAL:
One wire connects to a 12 volt source, the other wire is switched ground by an ECU PWM output that can drive 1A or greater.
