I actually believe phone GPS is how Hammer canadian track calculates their 1/8mi times. Or did he run an 1/8 kilometer track?

That's not quite true since my car covers a 1/4 mile in the 1/8 mile. It's without precedence

Ahahaahahahahahahahhahaahhahahahahahaha.
If you're relying on a phone app for quarter mile numbers, just give up while you're ahead.

You have to take it to the track to figure that out. The new Mustangs have timers built in. My girlfriends car was off .2 tenths in the 1/8th and dead on the mph.

I used a G-Force on and off the track before and it was off by a tenth (read I went a .1 faster than what I really did) in a 1/4 mile run.

The slower the car, the more accurate it is.

You mean G-Tech right? Those in my opinion are accurate. My bro has the first gen one and he verified with track times they are almost dead on. The MPH reading 2-3 high though.

Yes, G-Tech is the correct name.

Guys I just downloaded the "Race My Shiz" app and apparently topping off my power steering reservoir gained me a full second in the quarter. With no other changes, I'm going 10.80s at 124 in the 1/4.

Good pass! You have 10.5s in it for sure with a better 60ft.

Good kill. I like how the track was like 'lol app, you can't match me' and then downshifted and left it in the dust.

Throw some octane booster, a tornado, and some helium in the tires you'll be cracking into the high 8's .
