The ELEVATE Volvo C30 T5 Turbo Control Valve (TCV) Boost
Solenoid is designed to deliver consistent, optimal boost pressure for
your vehicle. Utilizing a premium quality, super fast acting, aluminum
bodied valve, our TCV is built to last and provide superior performance.
What is a Turbo Control Valve (TCV)?
In simplest terms, a TCV is an electronically controlled valve that
is controlled by the Engine Control Module (ECM) to manage turbo boost
pressure. It accomplishes this by taking the electrical signal from ECM
and opening/closing a valve which regulates the pressure applied to the
turbo wastegate actuator.
Do I need a new TCV?
The factory TCV is manufactured of plastic and mounted to the
turbocharger housing (a very high heat area). The factory TCV will
likely perform adequately for a length of time on a stock vehicle with
no modifications, but will eventually fail in time as it is a wearing
item (valve constantly opening and closing). On tuned vehicles, greater
demand is placed on the TCV, which may cause a stock TCV to fail
sooner. If your TCV fails, boost will be limited to only 5 to 7psi,
depending on the spring pressure in the wastegate actuator, which
severely limits performance. Those with a Performance Software Tune
which increases boost pressure will benefit from our TCV with more
consistent boost delivery and the long lasting durability that our
What makes the ELEVATE TCV different than others on the market?
Quality, design, testing and fitment. The valve we use is the best
available on the market and is stable over a wide temperature range. We
tested several different iterations of this and other valve types to
determine which is most compatible with the stock engine management
system. This translates to very little "learning" time for the engine
management to adapt to the valve. When energized, our valve responds in
just 4.2 milliseconds and closes in just 2 milliseconds. Our TCV uses
steel, zinc plated hose connections at the valve to prevent leaks or
breakage that is possible with cheap, plastic fittings that fatigue when
exposed to heat. All electrical connections are weather sealed. Our
TCV is mounted up on the firewall with an adjustable aluminum bracket,
keeping the valve away from damaging heat. Our kit includes 54" (137cm)
of US made, high quality black silicone hose. We evaluated cheaper
silicone vacuum hose from several suppliers and found the quality to be
far inferior to the thick walled hose we include.
The ELEVATE Turbo Control Valve is a direct replacement for the factory TCV.
