This is part 2 of a comparison between the Cobb Stage 1 tune and the stock tune (see other video), on the same piece of road.

-Here is the full 1/4 mile time slip on this run, according to the Cobb AP:

60'.............2.562s (pathetic)
330'...........6.232s
0-60mph...5.440s
1/8mi........9.274s@82.019mph
1000'........11.907s
1/4mi.......14.139s @ 101.023 mph

Observations:
(a) Launch: No difference b/w Cobb tune and stock. Either way, the launch is horribly boggy. I tried many different launching methods: full brake torques, mashing pedal, and everything in between. It didn't seem to matter because I always ended up with 2.4-2.5. ECU prevents hard launches as a safeguard to protect the CVT. Nevertheless it should do better than 2.5 seconds to 60ft, which is a little pathetic. If the launch can be improved, the CVT WRX has great potential. If the 60ft time would have been something normal, like 2.0 seconds, the low-14 second 1/4 mile in this video would have been in the low-13's, which would be quite impressive for a 2L car in nearly stock form.

(b) 0-60mph time improved from stock by about 0.4s, from 5.8s to 5.4s. Considering the inability to launch, this is quite good. For example, if you take away the launch from a manual wrx (and just mash the pedal from a stop), you are looking at a high-6 or low-7 second 0-60 time.

(c) 1/4 mile time improved by about 0.7s, from 14.8s to 14.1s.
The most noticeable improvement occurred from 80-100 mph....notice how the rpms are locked at 5500 rpms, while the MPH increase -a very cool feature of the CVT.

(d) WRX CVT vs 2.5GT: This 17 WRX CVT would lose a standing 1/4 mile race to my (automatic) 2009 Impreza 2.5GT w/ Cobb Stage 2 tune (which ran 13.7@100mph). However, in a rolling race, I think this 17 WRX would win. The 2.5GT had a much stronger 3k rpm launch (see my 2.5 GT videos), but the CVT pulls better on the top end (despite being 0.5 liters down).
