Project 718 Cayman T: Part 4 – Track Day Baselines

  • Khiem Dinh

At Streets of Willow, I pulled nearly identical G’s as I did at PECLA.

On the stock alignment, the edges of the front tires take a beating.

The rear tires are not as bad as the stock alignment does have a bit more camber in the rear.

I’ve never had cross-drilled rotors before. There is a bit of pad material built up in them.

The race-gas concentrate is doing the job of keeping knock away as show by zero adjustment on the ‘Ignition map RON dependent’. The ‘K010’ exhaust temperature is pre-catalyst and ‘K014’ is post-catalyst. The catalyst has thermal mass, so it acts like a capacitor which is why the temperature of the exhaust post-catalyst is more stable. The exhaust temperature drops between 100C-150C going through the turbine wheel of the turbocharger, so we can estimate that exhaust temperature pre-turbo is in the 950C-1000C range. Peak exhaust gas temperatures limits are typically 980C for grocery getter everyday gasoline turbo engines and 1050C for performance engines.

    Using the Launch X431, it’s hidden somewhere under Porsche Stability Management which I think is under DCM. I had to actually use the search bar using the term ‘PTV’ to find it.
