Hi,

Finally got some data.

Ran a few simple tests, in the first half of the graph you can see that I spent a minute driving in a figure of 8, you can see the G Force in the red line transfering from one side of the car to the other as I exit one loop and start the other opposite loop.

In the second half of the graph you can see that I ran some acceleration and braking tests, this is plotted in the pink line, acceleration is above the line and braking below the line, acceleration is about 1 G, braking is about 1.5 G, lateral forces represented by the red line in the figure of 8 loops are getting close to 2G.



Will put more data up on my blog when I have some longer runs and tried a few different set ups with tyres and adding weight.

Duane.

Hi,

Put some G-Force plots up here -

These plots are using worn out yeah racing tyres, I have some new ones using M-Grips on the front and will get some comparison plots with sweeps tomorrow.

I would love to see that!

Send your car over here and we'll document everything from unboxing until it's put in it's grave.
I know it would look very good in slow motion.. Just right before it hits the CURB (not kerb).
If only you pay more attention in school, you would've probably got right.


Let's hear it from you smarty pants..

Kids.. laughing
