Product Description
We recommend servicing your valve every 3 years, or 20,000 miles, whichever comes sooner
The FMDVMCS is a sandwich type adaptor that fits between the existing electrical solenoid and the turbo charger housing on the BMW Mini Cooper S N14 engines 2007/08(R56/57 *), Peugeot 1.6 turbo engines as found in the 207 and GTI , 208 GTI, 307, 308 and Citroen DS3.
On these engines, built into the turbocharger housing, is a bypass facility. This allows charge air to be recirculated around the turbo charger from the boost side back to the intake side. This recirculation path is opened and closed by means of an electrical connection from the engine management, to a solenoid that is mounted on the turbocharger housing. As you accelerate, the turbo charger vanes are spinning and boost pressure is increased, literally blowing into the engine cylinders. Then when you change gear, you take you foot off the accelerator momentarily, select the next gear, and accelerate again. As you take your foot off the accelerator the throttle valve to the engine closes. The problem here is that during this process the turbo is still spinning and the boost pressure that it is producing has no where to go. (This is a bit like putting you hand over a hair dryer so the air cannot get out) What happens at this point is the turbo starts to stall, the spinning vanes slow down (incurring alot of stress) and the boost pressure drops. When you open the throttle valve again by pushing down on the accelerator (demanding more power) the turbo has lost its momentum, boost pressure and there is a pause or a "Lag" before the engine is producing the required power once again.
To combat this loss of power and stress on the turbo, a recirculation or diverter valve is used. On the Mini, when the throttle valve closes, the engine management opens the recirculation route around the turbo. This gives the charge air an alternative route and allows the turbocharger to keep spinning so that when you accelerate again there is no "lag" or waiting period. This system works well and is adopted by nearly all vehicle manufacturers on turbo charged petrol engine applications. The only downside to this system is that a turbo chargers produce heat. (The hot air that leaves a turbo is cooled by passing it through an intercooler before it enters the engine. The cooler the air the more power is produced). By recirculating the hot air back into the intake side of a turbo the temperatures increase. This is where the Blow Off or Dump valve plays its part. By expelling the charge air to atmosphere rather than recirculating it, you do not increase the intake air temperature but you do allow the turbo to keep spinning. The side effect which is unacceptable to most vehicle manufacturers is the noise of the valve expelling the air.
By fitting the FMDVMCS between the existing solenoid and the turbo housing (this involves removing only 3 bolts) the air is re-directed to atmosphere rather than recirculated. It should be noted that the engine management also uses this valve to decrease engine power when necessary. An example of this is by the (DSC) Dynamic Stability Control system. Although you would not normally hear this occurring, when a blow off adaptor is fitted you may well hear the air being expelled when the DSC operates (going too fast around a bend for example).

Do not use aggressive (acidic) car cleaning products, particularly traffic film remover solutions or shampoos to clean your intercooler, radiator, or oil cooler. The use of these products can damage Forge Motorsport cooling systems and invalidate your warranty. These are often found at car washes. A light, warm, soapy solution (free of harsh acidic cleaning compounds) should be used to clean you cooler and thoroughly rinsed away. We recommend that you should inspect your product on a regular basis for bent and/or crushed fins. Any bent fins should be carefully straightened to allow ambient air to pass through the core face. At the time of installing your Forge radiator, an approved coolant must be used and added to the coolant system. Be sure you never mix coolant and always use distilled water.
This warranty does not apply to any defect in the goods arising from fair wear and tear, wilful damage, accident, negligence by you or any third party, use otherwise than as recommended by the supplier, failure to follow the supplier’s instructions, or any alteration or repair carried out without the supplier’s approval.

Expert Answers
Will this fit the 64 plate ds3 ehdi please? Dv9 engine.
Hello , sorry this is not compatible with a diesel engine
Hi does this item fit Peugeot RCZ GT THP 156 1.6 petrol from 2011. Regards
Unfortunately, not, this blow-off spacer will physically fit but will induce engine check lights and potentially put the engine into limp mode. The only blow of valve option we offer for the 156 BHP model is the part number FMDVR60A.
