I did a pocket DYNO using my I-Phone, these are the results, anyone else use this app?
max power = 442 rwhp
0-100kph= 7.46 secs
Car e39 m5
17” x 8” snow tires
Trunk full of cottage crap drinks, sleeping bags etc.
There are more reading but I thought these are the important ones. I am pumped about the numbers not sure how accurate tho!
