ensuring legal cars

[tderonne]

I was reminded a week or so ago that the Club has a non-teardown procedure for checking transmission ratios. I had completely ignored that (blame being old) so this is going to the top of my potential "write paper on" list (e.g., for the ARRC and IT Fest).

Large performance potential + easy parts cheat on VWs + cheap protest = UH OH

I've done it at Waterford. Simply roll the car in gear a certain number of engine revolutions (1 or 2). Do it for two or three gears. The ratio of the distances traveled matches the ratio between the gears involved. Won't tell you exactly what ratios are in there, but it's the relative gearing that's important anyway. Takes a few folks to push it in gear, but it works out very accurately.
