i phone owner's

my son got the newest i phone this weekend,a friend came over to see him while having a few brown pop's looked at the duster,and mentioned we wished we could get it dyno'ed to see what horse power ect it had ( we did not build this car but it was built to drag )the friend then said that he downloaded a program called dynobox for 5 buck's and does everything a dyno mach. does, you just need the weight of the car mount the i phone on the dash with the holder they sell and go. it tells hp. speed in distance ect. he had his car done last year with his car club and it matched the dyno's number's. hope i,ve got a few nice day's this weekend going to get the car's weight take her out and rip and try
ps. the web site is www.car-vs-car.de/dynobox/
it's in german so check it out an'it new tech. great
