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?

I'm not sure what kind of car you're trying to ultimately end up with but I know what I my goals were. This is or could be pertinent to what you are doing. Its a fine line, when building a modified 914 (or any car), between maintaining the integrity of the original car or basically building a race car/tube frame.

I certainly wanted a floor pan car that was comfortable enough to drive on the street, maintain a virtually stock GT appearance, and finally, have a level of performance to run the tails of a modern Cup car. Difficult to say the least. My wing and splitter come off in a matter of minutes but I like them on...so on they stay.

I like what I see you doing but I just don't know what the end-game is or will be - time will tell.

Here was my finished product - nothing really denoting it is a highly developed 600 hp well mannered car. Allots going on under the skin...

I look forward to seeing your solutions and ideas vetted out...not that I can help you in the least but if I can be helpful, shoot me a PM.

PS: One more thing, at the end of the day, safety is king and takes priority over comfort and aesthetics - it isn't everyone's cup of tea, but suits my palate just fine.

Cheers!
