BOlt-On Performance
The idea of the Carrera 3.2 Plus exhaust system was, like many good ideas, born over a cup of coffee. When Martin Pedersen of JP Group and Matthias Hoeing of Hoeing Autosport were done discussing dyno results of the newly developed 41mm SSI heat exchangers, they both stared into their coffee mugs and a number of „what if…“ questions emerged…
„What if we made an SSI exhaust system just for the Carrera 3.2? What if the heat exchangers came with a crossover heater pipe that connects seamlessly to the factory Carrera 3.2 heater air ducting? What if this exhaust worked well with the original spec C3.2 engine AND with C3.2 engines modified for performance? What if the user could choose between a version with catalytic converters and one without?“
The SSI Ethos
So, honoring the ethos of SSI founder John Daniels, Martin and Matthias went to work. The two, along with the highly skilled team of craftsmen and technicians at the SSI headquarter in Viborg, Denmark, the input of some industry veterans, and rigorous dyno testing, answered the „what if…“ questions and brought the vision to life.
Specifications
- Conversion of a performance optimized 3.2 litre Carrera engine into a free-flow system. Free-flow allows the engine to breathe giving a increased preformance.
- Ø41mm OD pipework in combination with Ø60mm inflow to the exhaust. This system is specifically engineered to generate increased HP from an enhanced engine.
- Easy Installation. No need to replace the engine tinware as system design allows to fit with standard G-model tinware.
- O2 sensor on both left and right side allowing you a more precise measurements allowing you to optimize preformance.
- All made in AISI304 stainless steel. High quality stainless steel ensures durability of the system. This gives you peace of mind when driving knowing that the system can handle any kind of punishment you throw at it.
- Large tail pipe for an amazing look and sound. Tail pipe outlet Ø70mm for optimizing the sound outlet from the system.
All sets have been on the dyno for extensive testing
The following diagram shows a comparison on an optimized Carrera 3.2 engine between the Hoeing by SSI Carrera 3.2 system and a competitor’s system which is much more expensive, requires intricate installation and, most importantly, has significantly poorer heating performance.
*Horse Power gain is depending on engine condition, fuel, lubricants etc. JP Group or Mathias Höing can not be held responsible for any specific gain valule
„doing it the right way“
Matthias has been building Porsche engines and servicing Porsche race- and sports cars for over 25 years.
