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.

Works and last
Color: White, Size: 6 Feet, Style: 1-Pack
The product material and length are as described. I haven’t had a problem with this cord yet and have traveled with it quite a bit. It works on my Google phone as well as my iPad. So far it seems to have great durability and it’s easy to use

Reliable cable that checks every box
Color: Black, Size: 6 Feet, Style: 1-Pack
I've been using these and they have been great across the board. Charges fast, the 6 foot length is perfect for reaching an outlet without being right on top of it, and the build quality feels solid and durable. The USB-IF certification gives you peace of mind that it's not going to damage your devices. For an Amazon Basics cable the quality is genuinely impressive and the price makes it a no brainer. Stock up on a few and put them everywhere you need them.

Necessary for some devices
Color: White, Size: 6 Feet, Style: 1-Pack
Necessary for USB-C charging non USB-C compliant devices. Not all devices will charge on a USB-C to USB- C connection. USB-C is a protocol that many devices do not follow but have the same connector.

Continues to exceed expectations
Number of Items: 1
This product blew me away. I was on the skeptical side after reading some of the negative reviews, but I have never had any issues. The charger is very fast and charged my phone in 2 hours from <5%. That's faster than some of my corded chargers. The cord and charger are of very high quality and even withstood my cat biting at it. Unfortunately, it does not include a charging block/usb wall adapter, but as long as you use a block/wall adapter that can support the charger (I used a Samsung fast charging block), it works great. The product will even blink if you are using an incompatible block. The rubber on the bottom of the charger prevents it from sliding around, and the overall appearance is slick and great. The product took less than 1 minute for me to set up and is very easy to use. Overall, it's an amazing product for an amazing price. Regarding some of the negative reviews; I see lots complaining about how hot the product gets. My block and the charger itself did get warm after extended periods of charging, however, there are safeguards that will pause charging if either get too hot. It hasn't gotten hot enough to be worrisome or even activate the safeguards, so I am not concerned about it at all.
