Specialty repairs are not offered at your average repair shop because most repairs of this nature require factory training, specific tools, extensive experience and a unique knowledge to execute them properly. Excelerate Performance has brought all of these requirements together into one shop so that your specialty repair doesn't become especially disastrous.


The purpose of the intermediate shaft is to drive the camshafts indirectly off the crankshaft. By using an intermediate shaft, the speed of the chains are reduced, which is better for chain life. This basic design was used throughout the entire lifespan of the aircooled six-cylinder Mezger engine used through 1998. The inclusion of an intermediate shaft which drives the camshafts indirectly off the crankshaft has been a mainstay of the horizontally-opposed flat 6 engine utilized by Porsche. Unfortunately, due to how the crankcase was designed, there are no internal oil passages from which pressurized engine oil can be used to lubricate a plain bearing on the side closest to the flywheel


Exceperate Performance happens to specialize in the 996/997.1 model Porsche in particular. We find the reason behind this is, they are becoming more readily available and can be had in a reasonable price range. At this age though, they are starting to require more repair work and have accrued higher maintenance costs. These variables also opens up doors to becoming more accessible to those who modify their cars. Tuning upgrades are common because just by altering the programming you can reach a substantially higher than stock output. When you mix more power, with old parts with an unknown repair history, you can expect to see greater volume of failure. The turbochargers are a mechanical part and when requesting nearly double the boost pressure, they can fail. The turbochargers life expectancy is highly dependent on good clean oil too. We cannot stress on the maintenance factor enough. The 996/997.1 911 Turbo models came with Borg Warner manufactured K16 or K24 turbochargers depending on trim package. We are well versed in replacing the factory turbochargers, exchanging for their hybrid replacement variants or Tial Sport upgrades. So whatever it is you need, we can help with that.


This page will be updated in the future to update information and add services specific to Porsche. If you would like to see something added or have ideas, we would like to hear from you.
