The RaggDoll Difference
At RaggDoll Motorsports, we don’t approach turbocharging as a parts catalog exercise.
We treat it like architecture.
Every 1244 Ball Bearing unit is built around:
• Optimized airflow mass with controlled shaft speed
• Surge-resistant, stable compressor behavior
• Balanced turbine drive pressure strategy
• Precision machining and assembly standards
The goal is simple:
Deliver power that feels factory-refined — only magnified.
No drama.
No band-aid tuning.
No compromises in drivability.

Who It’s For
The 1244 Master Turbos are for the McLaren owner who wants:
• A car that pulls harder everywhere
• A setup that supports serious power without sacrificing composure
• Performance that feels as sharp as the chassis looks
• A build that reflects intention — not impulse
If you’re chasing noise and flash, this isn’t it.
If you want control, authority, and execution — welcome.

1244 — Where Airflow, Control, and Execution Align.
Power with Purpose.
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!
