Porsche Cayman 987.1 New Dash Gauge Face

Recently I completed a task on my wife’s 06 Cayman S, which was to replace the dash gauge face overlay. As a Christmas present, I had given her an IOU to replace her horrible sticky HVAC control knobs and to replace the faded dash guage face. The replacement of the knobs is done and discussed … Continue reading

83-85 Porsche 944 – Vacuum Hoses

A thread popped up on Rennlist recently regarding vacuum hoses on early cars. The following is not definative but it may help. As an aside, the Y shaped venturi tube is shown in the photos.

Porsche Cayman S – Replace HVAC Control Rocker Switches

I did a job yesterday on the wife’s 2006 Cayman S that went surprisingly well and made a big improvement to the cosmetics of the car.

Horsepower Measurements in Car Using the Speedometer and a Stopwatch

Note that the 944 uses a “transaxle” which is located at the rear of … Continue reading

Porsche 944 Engine Rebuild – First Startup

Porsche 944 Track Car- Upgrades to the Steering

As I originally set up my track car, I had taken the power steering rack that came with the car, removed the hydraulic fluid, and plugged the various openings.

In Part 4, we installed the cam tower. I have so far skipped over items like the oil pan, oil pump, water pump, etc. In the great scheme of things, these could be installed by now. Here are a few pointers. First, we will look at installing the oil pump. When you installed the crankshaft … Continue reading
