Default EQ - 2010 STI - EQ Stage 2 Block and Heads, ATP GTX3071, TMIC, 91 Octane

This is a car we built recently. He just finished the break-in and came in for the final tune:

Event: Custom Tune/Dyno
Location: Equilibrium Tuning - Fairfield, CA
Ambient Temp: 75 degrees Fahrenheit
Elevation: ~100ft above sea level

Car: 2010 Subaru STI
Tuner: ED @ Equilibrium Tuning
Peak HP at RPM: 338whp @ 6350RPM
Peak Torque at RPM: 335ft-lbs @ 4200RPM
Target Boost: 20psi
Fuel: Cali 91 Octane

Engine/Power Modifications:

EQ Stage 2 Shortblock
EQ Stage 2 Heads (stock cams and valves)
ATP GTX 3071 Turbo with integrated EWG
Process West TMIC
Perrin 3" Inlet
Tomei UEL Headers + UP
EQ 1000cc Injectors
Walbro Fuel Pump
EQ Custom Tune on 91 Octane

This is the first experience I've had with the GTX3071. It seems to make similar power to the GT3076 with slightly better spool. On the street we saw 20psi by 3800RPM in 3rd gear. The car drives very nicely and response feels great all around. Next up is 100 octane or E85 .

*** Standard Dyno Chart Disclaimer ***

This dyno reads low and should be compared to the lower reading mustang dynos. Here are some proven numbers and trap speeds for reference:

Stock 02-05 WRX - 155-165whp
Stock 04-07 STI - 215-220whp
Stock 08-11 STI - 190-200whp

265-275whp - 107-108mph traps
300-310whp - 112-113mph traps
325-335whp - 115-116mph traps
350-360whp - 118-120mph traps
