1993 Mazda RX-7 Touring Edition
40mph-70mph Test Results = 4.75 seconds


I did two runs in each direction on what looked like a level stretch of highway. There was little or no wind and the temperature was probably around 68 degrees. The tachometer and speedometer were video taped on each run for precise (frame by frame) analysis on my computer to ensure accurate times. I had about a half a tank of gas. The video footage above is of the fastest run. It's not really very interesting to watch, but it shows what I was working with.


Car Mileage: 126,000

The car is equipped with a Fluidyne radiator and silicone vacuum hoses, but is otherwise stock.
