07 WRX Wagon, 64k miles
Stock trans. - gears, clutch, flywheel.
VF43, DW 750cc injectors, STi tmic, Invidia catless 3" exhaust, Cobb Tuning SF itake, tuned by Sean Ivey. Made 321awhp / 343awtq @ 21psi.
Clutch slips in 4th at WOT in low RPMs. Otherwise it's fine. If you're going to be on a stock 5 speed, don't shift much below 2,500 RPMs. Lower RPMs = more load on your clutch / trans = shorter life span. Barring 6,500 RPM dumps, no-lift shifts, and other completely unnecessary driving habits on the street, the stock drivetrain will handle the power no problem.
EDIT: looked at the dyno sheet again, max boost was 21psi.
