Get yourself a G-Tech Meter. It can tell you quarter mile and 0 - 100km/h times including terminal speed. It will also measure cornering G's, acceleration and decceleration G's. I have one and have found it to be within 2 tenths and 1 mp/h of the quarter mile times I have done at Willowbank. Very cheap to buy on Ebay too.

try braking & accelerating in & out of corners

The only prob with lap times...is waiting to get another chance to drive at the same circuit, and also, there are too many other variables on a lap.

Like track temp, tire temp, driver skill (mine varies a little too much I think), the list goes on...

If I can find a good bit of bitumen off public roads to do my testing - I could test whenever I wanted....that's the concept anyway.

LAPTIMES!

Once the Datto is back together I plan to modify the car in stages, and evaluate the effectiveness of the mods in acceleration, braking and cornering.

To do this I'm thinking up a list of repeatable, objective tests I can do - that will show the difference of one mod to the next.

Here's what I'm thinking so far (without going to a dyno):
Acceleration: 0-100, 0-60,
