Unlock the full potential of your Porsche 718 Cayman or Boxster (2.0T / 2.5T) with the RaggDoll Motorsports MoonShine!! High Pressure E85-600 Race Fuel Pump (HPFP). The stock single-pump system is a known limitation when tuning these engines for high performance. Unlike the dual-pump setups found in 911 Turbo models, the 718 relies on just one — and that’s where this upgrade makes the difference.
This direct-fit fuel pump delivers 33% more volume than stock, supporting advanced power goals without the need for custom wiring, additional controllers, or dual-pump conversions.
The factory HPFP simply can’t keep up when tuning for more boost, timing, or ethanol blends. This results in pressure crashes, lean-outs, or tuning limitations. The MoonShine!! HPFP eliminates those issues, giving your engine the fuel it needs to make consistent, reliable power at higher loads.
While this HPFP upgrade is plug-and-play and works in many setups without tuning, we recommend proper ECU calibration for best results. Upon purchase, your tuner will receive access to calibration files and support from the RaggDoll team to ensure smooth integration and optimal fueling.
Whether you're chasing 400+ WHP on E85 or building a fully-tuned Porsche 718 track monster, the RaggDoll Motorsports MoonShine!! HPFP delivers the volume, safety, and consistency needed to take your build to the next level — all without compromising OEM fitment.
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!
