A customer/friend had us install a APS DR725 Front Mount (largest available)
and Aquamist 2d water injection System.
The STi 2.5 short block with stock WRX heads, compression around 8.8:1
running 12 degree of timing along with extrude-a-hone exhaust manifolds.
UTEC is the engine management system utilized on this car.
The previous dyno tune netted 333 whp & 340 ft-lbs @ 20 psi
the turbo spooled around 2800~2900 rpm.
and the post install tune netted 375 whp & 394 ft-lbs @ 23 psi
with 17 degree of timing. Even with the gi-normus fmic the turbo
spooled at 3200~3400 rpm.
will post dyno plots when I get back to the shop.
