A while ago I installed a cool app on my iphone. It's called Pocketdyno and it lets you dyno your car by using your phone. The way it works is that you install the phone in a solid mount so the motion sensors can measure the acceleration forces. The app then gives a lot of info like: 0-25 km/h, 0-50 km/h, 0-100 km/h, 0-150 km/h, 60ft, 1/8 mile and 1/4 mile (speed and time) and max g-force.
So last weekend I did a few runs and got the following results:
1st run: 0-100 km/h in 7,50s ; 1/8 mile: 10,03s @ 119,67 km/h
2nd run: 0-100 km/h in 7,32s ; 1/8 mile: 10,06s @ 123,00 km/h ; 1/4 mile: 15,20s @ 155.29 km/h
3rd run: 0-100 km/h in 7,45s ; 1/8 mile: 10,03s @ 120,42 km/h ; 1/4 mile: 15,32s @ 150.14 km/h
4th run: 0-100 km/h in 7,40s ; 1/8 mile: 10,05s @ 120,86 km/h ; 1/4 mile: 15,33s @ 150.45 km/h
Grip was a bit of an issue since the car is now on its winter tyres. I already had a lot of wheel spin when lauching with 2000 rpm. So the times could have been better, but the speeds look ok though.
