As there seems to be a bit of a bun fight going on at the moment in regards to quantifying improvements mods may or may not bring, I thought i'd start a thread helping the less engineering educated among us to rise to the task of actually measuring these changes in a slightly scientific way, or at least with more detail than 'it looks good'.
I'm sure there are people who can help out by offering practical suggestions of ways to measure aspects of performance.
I'll get things rolling by asking, how is a good way (without spending heaps on a dyno) of measuring acceleration on the cheap without too many variables being introduced.
Putting it on a dyno at $250 per hour is not in my budget.
I dont think I'm needing absolute measurements, and relative measurements are fine for my needs. By that I mean I dont need to know that i'm pulling 67.4 kw at the wheels, just that the car is faster or slower with X mod.
Is there any merit in buying a gtech type sensor???
I have my own 50m slightly uphill concrete drag strip on private property so the legalities of trials on the road can be ignored on that strip.
or is it more accurate to whack the trailer on to keep speeds down and pick two fixed points on a hill like two sign posts, hit the first one at 30km/h in 3rd and boot it, recording the speed attained at the second landmark???
