Product Description
After huge demand, Forge have developed the perfect dump valve solution for the Fiesta ST MK8 and Ford Puma ST, two vehicles that Ford launched without an OEM valve included.
Similar to our early days when Ford released the RS turbo Escort, Forge developed and lead dump valve technology to give the Escort owners the same technology as Cosworth did for the Sierra - with loud whooshes and prolonged turbocharger life, this really is one the favourite modifications for the Ford enthusiasts must have bolt on products.
As the engine does not have a diverter valve fitted as standard, Forge have developed a twin piston dump valve that not only gives you an incredibly loud sound when lifting off the throttle, but also increases the throttle response during gear changes by reducing turbo lag. It has been designed to help the turbocharger maintain its rotational speed ready for when you accelerate, whilst also taking the strain away from the impeller. Without removing this stress from your turbo, it could cause premature failure, especially on tuned engines and modified vehicles.
Our dump valve kit comes with two different rates of springs to accommodate for stock as well as stage 1 boost settings. We also have additional stage two and above springs available to order through our website depending on your vehicles engines modifications, including hybrid turbo conversions.
The Forge Motorsport solution includes all the necessary hardware and step by step instructions for any enthusiast with appropriate garage tools to fit at home within a couple of hours.

The FMINDK38 is the cold air induction system for Ford’s latest generation 1.5-liter 3-cylinder ST engine. Like with all manufacturers in recent times the need to make smaller engines more efficient and more powerful has been an engineer’s top priority, this then creates a problem for the aftermarket manufacturers to improve what is already fitted to the vehicle, nevertheless this hasn’t stopped us at Forge Motorsport. On a tuned vehicle this combination is an essential purchase as the OEM air box is found to be too restrictive to achieve the optimum power figures and smooth power delivery.
This beautifully crafted high flow charge pipe is for the Ford Fiesta ST MK8 and Ford Puma ST. This product has been created over many days and months of dyno testing and road testing to prove the products credentials. The boost pipes are a direct replacement to the original hot-side charge pipe which is rather restrictive especially at the turbo end. FMBP6 was developed to remove these restrictions and now features a smooth and enlarged bore size creating a vast improvement in air flow and a reduction in pressure drop.
Our performance inlet pipe for the Ford Fiesta ST MK8 & Puma ST fits between the air filter and turbo inlet pipe and is a highly visible component of the engine bay, accordingly its available in red, blue, grey and black. Its fully compatible with either the OEM filter box or our intake for this application.

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.

Expert Answers
Hi, I have the FMDV35 fitted to my mk8 fiesta ST and is booked in for a remap and I’ve been told I need the yellow spring fitted can you send me a link for the correct part?
Search for part number FMDVSU110, but please note the yellow is fitted to the valve off the shelf as standard equivalent and the blue spring is supplied loose with each valve kit as an option for tuned engines, yellow being weaker than the blue option.
FMDV35: what's the difference between the blue and yellow spring please, and do you happen to have an example of what this sounds like fitted to a puma ST, thanks.
Please see the boost ranges covered by the blue and yellow springs:
Yellow - 15-23 PSI (1.03-1.59 Bar)
Blue - 23-30 PSI (1.59-2.07 Bar)
And please see FMDV35 dump valve sound file link below.
