Apple names an app for you iphone that allows you to use the i-phones built- in accelerometer to measure drag racing preformance of your vehicle.

*Real- time G's , speed , and distance
* 0 to 60
* Estimated wheel horsepower
* Reaction time with simulated drag tree
* Eighth mile
* Quarter Mile
* Horsepower Chart
and a few others..

according to reviews of the product.. someone rand a 12.83 at the track @ 109 mph and then using the app, it said he ran a 12.85 @ 109 mph

Thats pretty accurate in my opinion.. Has anyone tried this?

My buddy has it on his phone and well be testing it later this week if anyones interested. Ill be posting results from it ha.

 

interesting...watching...

 

fyi - repost

 

i have Dynolicious for my ipod and if you set it up right its very correct. i brought it to the track with me one time last year and it was dead on.

 

thats awesome.. i did hear it has to be mounted well but im not to worried.. im just curious to how accurate it really is.

 

yeah it has to be mounted... you cant just place it on your seat or in a cup holder and expect it to come up with valid numbers. trust me i tried all that stuff lol

 

how accurate was it when you ran it?

 

it was pretty much spot on. once i had it mounted and set up correctly. it wasn't ever off by more then .1 but most of the time it was less then that.

 

awesome

 

I've got dynolicious as well... but haven't used it just yet. still trying to acquire a mount.

 

yes.
old.
repost.

welcome to the internet.

 

repost is fine as long as its not repeatedly in a short period of time.. the orig thread im sure is buried.. how accurate are the HP/TQ compared to a real dyno

 

if it was buried, i would have taken more than a few seconds to search and find threads relevant to it
