2020 STi 0-60 mph

--------------------------------------------------------- 2020 Subaru WRX STi with just a Cobb stage 1 tune and lighter wheels (18" Motegi 131 traklites), everything else stock. -Accessport Flat-foot shifting set to 6800 rpms (note how revs jump forward during shifts), -Accessport Launch Control: not used, -Accessport data for 0-60 mph and 60 ft times shown at end of video, -Air temp = 58 deg, elevation = sea level, full 1/4 mile run here https://www.youtube.com/watch?v=ivIjyKAn-Oc -------------------------------------------------------------------- EDIT -in light of the comments/complaints about abusing the car: please read below: There are two important details that should be noted in this video before passing judgement: (1) The wheel spin at launch. (2) The flat-foot shifting feature of the Cobb tune. Before continuing, I should note that I have been drag racing since 2001. I don’t say this to "show off," but rather to indicate that I have some racing experience -both with muscle cars and with awd/turbo/4 cyl. Over the years, I’ve made plenty of mistakes…but I’ve also learned from them and learned ways of pushing cars to their limits on the dragstrip, while minimizing the wear/tear of racing. Regarding (1), During high-rpm launches on an awd car like the STi, if the tires instantly hook, all of that energy/momentum in the engine/flywheel has nowhere to go, and will be instantly absorbed by the drivetrain. That "shock" is what breaks things. Additionally, when the tires grab, the RPMs drop quickly, causing the engine to bog and stumble -which will hurt your time. HOWEVER, if the tires break loose and spin (like in this video) it will take most of the load off the drivetrain (energy/momentum is transferred to spinning the wheels instead of absorbed by drivetrain). Unlike RWD muscle cars, a little wheelspin in the STi is actually a good thing: it's easier on the drivetrain, and keeps the engine revs high (preventing bogging/stumbling). It’s a good method that I’ve used a lot with my Evo on the dragstrip (best launches always came with a nice screech off the line). It does take practice/skill to be able to spin the tires on an STi at will. Release the clutch pedal quickly (without dropping it), and simultaneously floor the gas pedal. If you release the clutch too fast, you will bog. Too slow, and you'll smoke the clutch. You want the clutch to hit the tires hard, so they spin. When done correctly, it's not abusive to the clutch at all (same argument about energy transfer holds....). My Evo's clutch lasted for 5 years, and over 100 passes on the dragstrip launching this way. After the run in this video, there was no "burnt clutch" smell whatsoever (a good indicator of whether or not you did it right). The all-season tires and lighter wheels made it a lot easier to break the tires loose. I don't recommend launching with the OEM wheels/tires. The OEM wheels are heavy and the OEM summer tires are sticky (not a good combo). Regarding (2), powershifting or flat-foot shifting refers to holding down the accelerator pedal to the floor through the whole run -even while you shift. Compared to other cars I've raced, this STi is slow...so it's pretty easy to powershift (feels like "slow motion" to me). When enabled in the Cobb tune, the “flat foot shifting" feature momentarily cuts off the ignition when you shift. This takes the load off and reduces wear/tear on the synchronizers in the transmission -like shifting gears with engine off. The idea is similar to old school WOT boxes. My mustang had a faceplated transmission (no synchronizers), but I never tried a WOT box. So I was naturally curious about this Cobb feature. I know (unfortunately) that powershifting kills synchronizers, but the Cobb feature adds a measure of protection, which is why I didn't mind trying it for this video. /End EDIT ------------------------------------------ 0-60 times -Stock: high-4's/low-5's -Cobb stage 1: mid/high-4's -Cobb stage 1 + lighter wheels + A/S tires: low/mid 4's
