Accuracy Pretty accurate computation..Try a smooth rolling start use a gear tall enough so that the system will have enough time to analyze it. A gear that can run up too 100-120kph before revv limit. Don't revv your 1st gear hard, just settle for that tall gear in a low 1500-2000rpm and just puch till revv limit. But before you run. You just have to know how to input the right frontal area, drag coefficient and other stuff. Make sure there is little or no wind when you run it.
Spot on I installed this app in my 10" tablet and compared it with the local racetrack drag strip racing equipment. It is so close that it can be regarded as accurate. (timing was spot on and the speed was 1km/h lower than the timing equipment) I also use the app with my Sony Xperia Z5 compact, but the phone is so slow you cannot use the results.(0-100km/h is over a second slower than the actual time) I guess the processor in the tablet is just superior enough to record accurately. Excellent App.
Able to dyno from any starting speed! If (1) you are able to obtain every value possible for your vehicle, such as frontal area, drag coefficient, accurate weight, and (2) you understand EXACTLY how to operate the program, you can get a decently accurate wheel horsepower (WHP) reading compared to a real dyno pull. The only drawback is that Racedroid currently can't save multiple profiles for different vehicles.
Unbelievably accurate! Last year on a Professional Mustang Dyno in Joliet, IL my car pulled 402 HP and 357 ft-lbs of torque. This app after calibrating had my car at 398 HP and 354 ft-lbs of torque. 1% gap between this free app and very, very, very expensive dyno time! I love it! Wish it could do landscape mode.
I have developed a True hybridturbine air to water Intake system. My car is rated at 252hp 262torque. After i installed my system i couldn't understand all of a sudden I'M smashing alot of the higher performance cars and even taking Ecoboost trucks of the line dam wtf then i found this app it has changed my life. 89.16 HP@330rpms 518.00torque@330 rpm. At a 100 my results were 373hp@4740 rpms 413.00torque@4740 rpms wtf 80 to 120 hp gained and i have invented the holy Grail of air intakes systems thanks.
App works well. Dyno seems very accurate if you put the vehicle's full weight in. Only problem I'm having is the dyno graph seems to stop measuring before redline. I had my foot to the floor until bounced off the limiter but the graph looks like the throttle was let go 1000rpm sooner. So I can't see my actual peak whp.
