Turbo Fuse Boost Controller
The new GFB Turbo Fuse is an important safety
measure against a disaster. As its name suggests, it offers
reliable and effective protection for your turbocharged engine
against over-boosting. Simple to install, it can be fitted to any
turbo car with an existing blow-off or bypass valve in less than a
minute.
How Does It Work
The Turbo Fuse works with the blow-off/bypass valve to relieve
excessive boost pressure when triggered. It does this by shutting
off manifold pressure to the top of the blow-off/bypass valve,
which will subsequently blow open and relieve the boost
pressure.
The Turbo Fuse operates in only two states either on or off.
Unlike ineffective pop-off valves of a bygone era, which simply
comprised of a spring-loaded valve, the Turbo Fuse does
NOT slowly creep open as boost exceeds the trip-point.
The response is instant and complete.
Who should use a Turbo Fuse
A Turbo Fuse can help protect ANY turbo engine.
Over-boosting can occur as a result of a sticking wastegate, popped
or split wastegate hose, a faulty boost controller, or even an
accidental incorrect boost adjustment. Of course, an over-boost
will invariably occur during the times when you shouldnt be
watching a boost gauge. Even worse, a large over-boost can destroy
an engine in less time than it takes to read this sentence.
My car has a factory boost cut anyway why do I need a
Turbo Fuse
Most turbo cars feature an electronic fuel cut that performs a
task similar to the Turbo Fuse. However, in the world of modified
turbo cars, it is common practice to bypass or disable this feature
(through the use of a fuel-cut defender or similar product) in
order to intentionally increase boost for better performance. In
this case, the engine is left unprotected.
In addition, anyone who has unexpectedly hit the factory fuel
cut will know that it can catch you by surprise. The engine loses
all power, which can be merely annoying or downright dangerous
(when overtaking for example). The Turbo Fuse is not as aggressive
in cutting the engine power; it is more like hitting a soft
limiter, which is much safer if it is unexpectedly triggered.
Features
- Protects the engine and turbo against potentially catastrophic
overboost
- Adjustable trigger-point
- Works in conjunction with an existing or supplementary diverter
or TMS valve to reduces boost pressure significantly
once triggered, and resets once the throttle is closed
- Safer than fuel-ignition cut systems engine power is reduced
rather than completely cut when triggered
