I recently bought some software for the Iphone called Dynolicious, this software basically measures the G-Forces that the car produces and calculates them in to acceleration speeds.. I don't know how it works in great detail, but many people have suggested that its pretty accurate.. Everyones knows that when manufactures quote performance figures they do so in such a way that the parts soon wear out, for example when testing the 2.2 vx220 they started in 2nd gear and I believe the clutch lasted 5 or so attempts before it was useless. Interestingly tho the Iphone software can read out by 0.25seconds up to 0.65seconds as proven here

Ok here are some of the 0-70 tests I ran.

Test 1



Results (in seconds)
0-10 MPH - 0.97
0-20 MPH - 1.87
0-30 MPH - 2.96
0-40 MPH - 3.84
0-50 MPH - 5.04
0-60 MPH - 6.63
0-70 MPH - 8.44

30-70 MPH - 5.48
30-50 MPH - 2.08
50-70 MPH - 3.40

Max Acceleration - 0.62 G's

Test 2



Results (in seconds)
0-10 MPH - 0.94
0-20 MPH - 1.73
0-30 MPH - 2.63
0-40 MPH - 3.82
0-50 MPH - 5.16
0-60 MPH - 7.41
0-70 MPH - 9.52

30-70 MPH - 6.89
30-50 MPH - 2.53
50-70 MPH - 4.36

Max Acceleration - 0.65 G's

Test 3



Results (in seconds)
0-10 MPH - 0.60
0-20 MPH - 1.31
0-30 MPH - 2.18
0-40 MPH - 3.25
0-50 MPH - 4.53
0-60 MPH - 6.22
0-70 MPH - 8.12

30-70 MPH - 5.94
30-50 MPH - 2.35
50-70 MPH - 3.59

Max Acceleration - 0.92 G's

Test 4



Results (in seconds)
0-10 MPH - 0.63
0-20 MPH - 1.36
0-30 MPH - 2.26
0-40 MPH - 3.35
0-50 MPH - 4.69
0-60 MPH - 6.49
0-70 MPH - 8.45

30-70 MPH - 6.19
30-50 MPH - 2.43
50-70 MPH - 3.76

Max Acceleration - 0.92 G's

Note* tests 1 and 2 were done on separate days
Note** tests 3 and 4 were done on the same day but inc passenger
Note*** all 4 tests were done starting from 1st gear and on a flat surface

At the moment the performance of my 2.2 is not too bad, the Achilles heel at the moment is having to change to 3rd gear to hit 60 which a remap should sort by taking the rev limiter to just under 7000rpm, my rolling times suffered with having a passenger with me in tests 3 and 4, but still managed to get better 0-60 times due to me trying a tad harder.

be interesting to see a comparrison of results against proper timing gear as opposed to what id call a gimick
