997 Cup car e-power steering, electric AC compressor and Webasto cabin heater. Very involved to add the heater to the factory system. Needed the WEVO 240 amp alternator to run the electrics.
All because I didn't want any compromises on the engine's output for track use but still be able to use it comfortably on the street.
The engine is the star of the build and is the full on Rothsport Racing 4.0L 993 based one, very close to the Gunterwerks 993s.
For accuracy, the torque Bill showed in his chart is flywheel torque for my engine from the engine dyno tuning.
Wicked is a good description. The acceleration explosion that occurs from 4,500 to 7,500 rpm on the 2700 lb chassis was alarming at first as it happens so quickly.
Fitting the new engine required some systems modifications.
Added a vacuum reservoir (for the brake booster), fuel tank vent filter and oil tank breather.
The engine's MOTEC 600 controller required a full removal of the Motronic wiring and ECU.
A few more build photos after I figured out how to resize them. Engine wiring harness Engine harness with MOTEC 600 1 7/8" primaries headers, GT3 muffler with bypass valves ITBs and Turbo fan housing with CNC impeller
