Experimental Weights

There is no Venturi effect. It was posted more for humor. Sometimes people will focus on irrelevant info instead of perfecting the basics. I'm all for good discussion, I love things that make me think. I love testing most of all. I will say don't take any ones word for anything. If you have the ability to test, TEST! What sounds correct in theory or looks correct on paper does not always translate into gains in PWD. The first few years of racing I didn't try a lot of things because of the "Already tried that, it doesn't work" When I started giving things a test for myself I found a lot of things that didn't work for others actually worked for me. Don't get sucked into the Venturi, Perfect the basics and then mess with the other stuff.

Crash, thanks for the answer. However I was never good at math. I am more of a visual learner.

Help me understand if you can.

If we have 3 elevations, A (weight high in the car), B (final elevation once the car reaches the flat section), and C (weight low in the car).

The difference of elevation A and C will always remain constant, correct? This constant difference will remain consistent even when the car reaches the flat section of the track, correct?

So the weight falls the same distance does it not?



Upon thinking about this again, maybe what you are saying is that the low weight will fall a longer distance not a greater elevation change? Much like a shorter WB car is allowed to fall a longer distance before the car starts to transition? Or is it related to the position of the weight while on the ramp slope?

Upon edit: ok, so I was typing while the other responses posted. The link to Randy's test was very helpful. One thing I did not see was how long his track was. So we don't know if it had a long or short flat section?
