trackaddict on a android.

It is a bit wonky but after a few test runs you get the hang of it.

It will video tape each run. When you are set to go press the record button and it waits for movement to start recording. I had mine flat in the seat.

on my first run it thought I ended the run off the coast of Africa and said my average speed was 1,324,203 mph. but it did capture data through 1/4 mile.

I just downloaded the app.. so do you have to stop it manually at the end of the 1/4 mike or does it do it on its own??
 
It looks like it stops itself at 1/4 mile. I downloaded the raw data to my pc and at 1200 to 1300 feet it stopped recording

I downloaded an app Track Addict and went out to a relatively flat long straight road. the road runs almost due east. The app came back with 26.35 s at 70.2 mph for 1/4 mile. I don't know how accurate the app is? The 1 to 2 shift was about 40 mph and the 2-3 shift was just under 70. I had a stumble at about 50 mph (I think it is a fuel starvation due to fuel heat vapor lock issue like i have at hot idle) but it cleared its self. on the return run same road opposite direction at about 50 the engine kicked and bucked and I let off the gas and it recovered but wasn't happy after that.

What was the rpm? Might it have been lifter pump-up. Your description of not" happy after that" kindof points in that direction.
50mph with 25.5s and 3.23s would be about 5500 with a 904

273 solid lifters, 2.93 rear ratio, 25.8" tires, 1st gear to 40mph = 3840rpm, 2nd gear to 70mph 3978rpm I don't have a tach so the numbers are calculated.
