Talking 335xi V2 - Datalog - 0-80mph in 8.1 sec

So I did a datalog of a 0-80mph run.

How does it look?

Max Boost : 14.9psi

1st gear Max boost 14.9spi
1st gear Lowest boost 13.3 (redline)

2st gear Max boost 14.7spi
2st gear Lowest boost 13.0 (redline)

3st gear Max boost 14.9spi
3st gear Lowest boost 14.1 (80mph)

Also, correct me if I'm wrong, but it looks like I did 0-80mph in about 8 seconds.

Boost looks good. And I guess since you aren't doing an aggressive launch 0-80 in 8.1 isn't bad but as reference I went to the 1/8th mile drag strip last week and did 1/8 mile in 8.1x @ 88 mph and lots of folks have done faster so I suppose a good 0-80 run would be around 7.5-7.7.

Time-to-speed and time-to-distance are two different things. You can't compare.

Steel,
Its kinda hard to really tell if you did a 0-80 in that time based on the logs. There may be slight lag compared to reality in the log. Best to use a Vbox or track to get an idea of your 0-whatever speed.

If you don't have the sport package, you may be butting against the speed limiter in 4th gear. In a standard 335 (non xi), I recall only being able to rev to ~6000rpm in 4th gear due to the 130mph limiter. So you might want to do the run in 3rd gear.
