Cobb 09 WRX Stage 2 Results
Here is a quick look at the latest results with our 2009 WRX. Our previous post (http://forums.nasioc.com/forums/show....php?t=1633679) outlined the results of this 09 with just an Accessport Protune. For the next stage, we added a Cobb downpipe combined with the SPT exhaust.
With a bit more boost, and a bit leaner mixture, we extracted 317 lb-ft of torque and 281 whp on Oregon pump 92 octane! Here is a look at the Stage 2 compared to stock. Note this is with the SPT exhaust, which isn't the freest flowing exhaust compared to some aftermarket exhausts. As you can see, the stage 2 setup has a huge torque gain everywhere. If you saw this post without a heading, you would think it is from a Stage 2 STI. Compared to the Stage 1, the addition of the downpipe gave us more torque across the powerband. As typical with the STI, the car responds well to a slightly leaner mixture. Here are two runs in the Stage 2 setup with the higher hp run targeting AFRs around 11.8-11.9 The boost used for the stock, stage 1, and stage 2 runs. Obviously the comparison to a Stage 2 STI in inevitable. This comparison is to an 07 Stage 2 STI with a real 3" aftermarket exhaust, and a bit more boost then the 09 WRX setup. The shape gives you a good idea about the 09 Turbo. It appears the 09 WRX turbo is indeed a VF43 sized turbo with the Legacy/WRX compressor cover. Last but not least, here is a look at the 09 WRX vs the 08 WRX, in stock form. As you can see, the 08 WRX has a torque advantage until about 4000rpm, at which point the 09 WRX takes over and runs all the way to redline. The 09 has more lag then the 08, much like the 08 STI vs the 08 WRX. We are going to add a larger TMIC this week, so look for some more results. Based on the numbers so far, it seems the 09 WRX is a bit underrated at 265 hp. This car is the sleeper of the Subaru lineup. With the longer 5 speed gears, it will give the STIs a significant challenge. Cheers, Jeff Sponaugle Research Caibrator Surgeline Tuning

Oh, and here is a look at this 09 WRX Tune vs my 08 STI last year as Stage 2. This isn't an apples to apple comparison, as I was pushing the 08 STI much harder (more boost), but it does shed some light about the dual AVCS and perhaps the compressor cover effect on spoolup. It seems as though the 08 STI is able to spin up this size turbo just a bit faster.

Nice job guys! I knew these things were beasts! Subaru needs to do something about the STi!
Our older gen STi's are slowly becoming obsolete...we need more power! Kind Regards, Ryan |

So if an 08 owner were to pick up a VF-52 and slap it on... will we be able to load a stg1-stg2 map for an 09 WRX on the 08? or will this require a protune?

I wonder if an FMIC would allow one to hit 300whp.
But this is a Mustang dyno so it reads low right? |

Any info on fuel injectors or fuel pump? Are you guys anywhere closed to maxxed out or did you guys replace them?
If not that's pretty impressive for a midly tuned WRX!! |

impressive, and with the injectors being nearly maxxed out, would that require an upgrade or would that be safe to run with stg 2? Also, any chance of slapping on an after market exhaust, something like a 3"?
