Horsepower Measurements in Car Using the Speedometer and a Stopwatch

Although I wouldn’t take it to the bank for obtaining a hard horsepower number for your car, it could be useful in making A to B comparison … Continue reading

Kevin Gross – Catellus Engineering

I have been worried about the noises coming out of the transaxle on my Porsche 944 track car. Based on his excellent reputation, I decided to remove the transaxle and send it to Kevin Gross at Catellus Engineering for a rebuild. Note that the 944 uses a “transaxle” which is located at the rear of … Continue reading
