Manufactured by RaggDoll Motorsports with billet aluminum, this blow-off valve guarantees superior quality and durability compared to factory plastic valves, eliminating common issues such as cracking and leaking.
The RaggDoll Motorsports valve features a lightweight, two-piece piston made of brass and aluminum, resulting in optimal responsiveness. Carefully engineered springs make these valves the most responsive in their class.
With a compact design and the ability to fit a wide range of turbos, from stock to any of our larger upgraded RaggDoll turbos, installation of the RaggDoll Motorsports blow-off valve is quick and easy. The valve comes with the option to run as a full recirculating valve or a partial open-atmosphere valve, allowing you to customize the setup to suit your specific application and give your Cayman/Boxster 718 (982) a little more character. Installation after engine cover removal is near effortless.

Whether you prefer a quiet ride or want to turn heads with that turbo sound, Raggdoll’s blow off valve will exceed your expectations.
Liza & most of the time Vince is amazing...lol. Nah, kidding, these guys are awesome folks to deal with. I purchased their Stage 2 turbo, turbo inlet, intercooler, engine tune, and high pressure fuel pump for my 2018 2.5L Boxster GTS and they're products and service have been top notch throughout the entire process.
Raggdoll Motorsports set up two dyno sessions for my Porsche Turbo S. The Porsche touts a 4.0-liter built engine and head work facilitated by Sam at ByDesign. Also has the XR ByDesign turbo kit with all the supporting mods. The first session the PDK kept transitioning out of manual mode. During the second session a boost leak at the throttle body boot ended the session early. We managed 812 hp on a Mustang dyno at only 20 psi of boost.
The people behind RaggDoll Motorsports have been in the game for a very long time and really know their stuff. They have a passion for modifying cars and are enthusiasts before anything else.
I purchased a RENNEN turbocharger for my 718 T. I had a special request, which was to get the turbine housing coated with Swain Tech white lightning thermal barrier coating and RaggDoll accommodated without hesitation even though it was something new for their team.
Hey All! Shout out to Liza and @Raggdolls718. Amazing customer service, product knowledge and a top quality product. Liza went out her way to accommodate my tight timeframe and the level communication and level of detail shared was amazing.
I purchased the Raggdoll Series One turbocharger upgrade and the turbo inlet upgrade from RMS for my Porsche 718 Cayman GTS and was very pleased with both the products and the customer service from RMS!
