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.

So close!
Size: XX-Large, Color: Navy
This dress exceeded my expectations, but the deal breaker for me is no pockets! I can't believe I missed that. The fabric is impressive for polyester. It seems relatively breathable, and it's a very nice mid weight that flows and drapes well. It is smooth and conceals lumps and bumps. The buttons are well made, and the placket does not gap. I ordered the navy blue and it's exactly as expected. Size XXL is exactly right for me at 48/40/50 and 5'6". It hits about 4" below my knee. I would prefer shorter at the knee for easier to wear as a duster. I wish it had pockets!

Classic dress at a great price
Size: Medium, Color: Black Ivory Geometric
I was shocked, in the best way when I received this dress as the material is thick and heavy. I was looking for a dress that I could take on business trips that was comfortable, stylish and didn't wrinkle. This dress checked all the boxes. It's a classic style that will never go out of style.

Runs smaller than my regular size.
Size: Large, Color: Hot Pink Leafy Floral Ditsy
Medium weight fabric and decent quality. Tight fit across bust and under arms and also waist. I am not a big busted woman although I am not so many inches different from bust to waist (it gapped at waist upon sitting. I had to exchange it for a bigger size. So my experience leads me to belive that this manufacturer sizes smaller than what I would expect from expensive clothing. For the price is a good choice if you remember to go at least one size up from your regular size.
