914 Chassis Stiffness, want input on chassis stiffness measurements Options

[Curbandgutter]

I want to check the stiffness of the 914 chassis two ways: the flexural stiffness (as in measure the shock tower movement as you lift it from the middle), and the torsional stiffness ( measuring the shock tower movement as you lift three wheels).

Then I want to input a 914 chassis into a 3d structural software that I use. I will design a tube chassis and check the flexural and torsional stifness with different tubing and thickness layouts.

Then construct the tube chassis and compare the real world results.

I want input from others as to how they would go about doing this. Or maybe give me some pointers. Or maybe someone already knows the factory stiffness?

What do you think?

It's been done. Most recently by anklebiter. Search for his build thread here.

I read the entire 52 pages and did not find any mention of what the flexural and torsional stiffness are? Did I miss something. The anklebiter biter build is where I got my inspiration to do a 914. I've owned two 914's one a 70 sixer and the other a 73 2.0 liter. Been away from the 914 world for 25 years now. But I'm back wiser, more patient and with 25 years of experience as a professional engineer. I used to do custom body work, rebuild engines and welding before I became an engineer. I figure I can do a pretty good job now. I recently bought a 74 and plan on tubing it, flaring it, speedster look, with an 8 cylinder (something small, high winding, light and with 180 degree headers). I will start a build thread soon. However, back to my original post.......
