My 2008 STi Stage 2
2008 Subaru Impreza WRX STi
AEM Cold Air Intake
Tsudo catless downpipe with additional resonator welded in
Tsudo catback exhaust
Tuned at HB Speed on January 24th, 2010.
The old redline was 6500 rpm, the new one is upped to 7250 rpm!
19 lbs of boost tapering down to 15 lbs
11.5 air/fuel ratio
315.8 horsepower at the wheels at ~5600 rpm, tapering down to 285 horsepower at the 7250 rpm redline
336.5 ft-lbs of torque at the wheels at ~3750 rpm, tapering down to 210 ft-lbs of torque at the 7250 rpm redline
A stock 2008 STi on that dyno will push about 230 horsepower to the wheels, so I probably made a 80-85 horsepower gain, which puts me around 380-385 horsepower
