I've been told the Cg for a 914 is around 16", but this seems high to me, since the pwertrain is so low in the vehicle. I finally got around to measuring it, albeit, somewhat inaccurately.
So, I borrowed some scales, weighed the car, raised one end 10" and weighed it again. This moved 20 pounds.... So, by my crude calculations and crude measurement that puts my Cg at 9.6 inches. Consisdering how low I run the car, seems pretty close to me. The middle of the engine sits at abou 10 inches. Has anyone else measured their Cg???? I'd like to get some confidence in my numbers. |

I haven't gotten around to doing it yet, but thanks for the opportunity to study the math. I think I would need the before and after weights to be more accurate. Assuming a 2000# car with 1000# front and rear to begin with and ending with 1020 rear and 980 front that would shift the cg back about .86". The car raised 10' in the front creates a 5.95 degree angle. My calculator says the cg is about 8.25" above ground level. It's been a long time and right now I'm not sure if the original location of the cg is important. I always thought the cg was pretty close to the centerline of the wheels and and engine. give me the raw data and i'll give it another try (IMG:style_emoticons/default/confused24.gif)
