RaggDoll Series oNe is our original powerhouse — a lightning-fast spooling, track-proven hybrid turbocharger. Engineered specifically for the Porsche 718/982 Cayman and Boxster S & GTS 2.5L engines, this unit is built to dominate your favorite canyon route or road course, all while maintaining factory-like drivability.
The RaggDoll Series One delivers over 500 wheel horsepower with the right supporting mods while still offering the fastest spool in its class, hands down. Although it was built to flow over 60 lb/min, we built it to be optimized at 440 to high-400s at the wheels effortlessly, all while keeping intake temps in check. It’s not just about power, especially with our platform it’s about keeping those air intake temperatures down. And one way to do that and make your intercoder work a lot less harder is have the right turbo for the power that you desire.
You track guys asked — we delivered.
The RaggDoll Series oNe was born from motorsport experience and customer demand. It’s the perfect upgrade for S model owners wanting a big performance jump without sacrificing spool or street manners. GTS owners looking to go even further than a 20% increase in power can step up to our Series Two — but if you want maximum punch with the quickest response possible, this is your turbo.
No Guesswork — Just Performance
This is a true plug-and-play VTG turbo upgrade. Simply transfer your OEM wastegate and VTG module (three screws) to the new unit. We do this to avoid damage during shipping and ensure you keep your known-good components — no random electronics, no mystery parts.
Whether you’re setting lap records or chasing down supercars on the freeway, the RaggDoll Series oNe is the lightweight fighter with a heavyweight punch.
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!
