Anyone else measuring G force on their Scoob ? Interested to compare results. Result below for my MY95 WRX RA running 23 psi boost (with a few supporting mods )



The dip at 0.8 seconds was wheelspin not a gearchange ! note how much time is lost changing from 4th to 5th almost a full second

that looks like an race technology AP-22 graph.

I've used one on my 97WRX 5dr when it was standard ( 11psi boost), I only kept recorded data for a 3rd gear roll-on, it gave a max of .35g somewhat less than the .5g your showing in 3rd.

I recall max in other gears being around
1st .55g ( .8g if slipping clutch on launch )
2nd .4g
3rd .35g
4th .2g
5th .1g

compare these to the figures on your graph, and you can see how much of a differance there can be between a std scooby and a well modified one.

 

How was the graph produced?

The graph was produced using the software supplied with the AP22.

It can also log power at wheels after entering some weight data and aero and mechanical drag factors (it tells you how to calculate this and it's only required once)

I've also found it very accurate for 1/4 mile and 0 - 100 mph timing.

A great tuning tool
