Also, we need a to say on our posts if this was on flat ground, incline, or decline.

I agree. A video or log isn't going to be perfect. VBOX would be ideal. BUT I wanted to make this as accessible as possible, so I'm fine with accepting videos and logs. If anything, they aren't any less accurate than all the Airboy/Virtual Dyno posts out there, because that is based off log data as well.

All runs should be done on flat ground. If you want to cheat and do it down a hill I guess no one will be able to stop you, but that's not really the point.

For instance, I have timed 60-90 on my wrx several times, starting at 60mph, and have obtained times from 3.4 sec to 3.9 seconds in consecutive sets of pulls. Who knows if I was starting right at 60 each time, or if my stopwatch was used accurately?

Pulling through 60 is noticeably faster, although with still inconsistent times due to using a stopwatch. Just wanted to clarify the rules here before I add my data.

20g on a 2 liter with 6spd doesn't like being floored from 50... lol

Here's what I posted when I originally did this.

I did it from a 30mph roll so my turbo was spooled up when I hit 50mph. Some might not agree with this, but I think it's the most consistent way. Basically just get from 50-100mph as fast as possible: use whatever gears you'd like, brake boost, start slower and go WOT through 50mph, etc. Just keep it to a flat surface and you're good.
I'll add a comment about this to the original post. Can't wait to see some more results!
