Bucky Lasek has been a customer of COBB Tuning for a number of years now. A true gearhead at heart, he loves being behind the wheel and enjoys being able to blow off a bit of steam when necessary. Being a driver for Subaru Rally Team USA, Subaru is obviously in his blood. He recently paid our COBB Tuning SoCal shop a visit to bump up the power output of his 2012 STI.
Bucky’s goal with his 2012 STI was to show what the car is capable of with the budget of an average enthusiast in mind. Simple is the name of the game here, every bolt-on part has a purpose. The car is equipped with a coilover suspension kit, upgraded swaybars, and basic bolt-on performance pieces to increase airflow through the engine. This is a car Bucky can take his kids to school in, enjoy a bit of spirited driving in the canyons outside of LA, or beat on at the road course. He originally came in a few years ago to have the car custom tuned on the stock turbo utilizing the COBB Accessport. The car made 321 hp and 364 ft/lb on a 50/50 blend of ACN91 and 100 octane fuel with an upgraded exhaust manifold, turboback exhaust, fuel pump, and intake.
Recently, Bucky approached us looking to step up the power of his STI. The car already had great low-end torque, he was simply looking to add more mid and high-end power to back up that torque. After a consultation with the crew at COBB Tuning SoCal, a short list of modifications was established to reach Bucky’s power goal.
- Blouch Dominator 1.5XT-R turbocharger
- COBB 1300cc Fuel Injectors
- COBB Fuel Pressure Regulator Kit
- COBB 3-port Electronic Boost Control Solenoid
- Accessport V3 Upgrade
All of that would be tied together with custom tuning on three fuel types – 91 octane, 91/100 octane blend, and E85. With the convenience of the Accessport, Bucky is able to switch between these maps in no time at all depending on the fuel in the tank.
When all said and done, Jon Hebbeln of COBB Tuning SoCal was able to squeeze out 431 hp and 445 ft/lb with the new setup on E85 fuel. For the every day driving on ACN91 fuel, the car is making 362 hp and 378 ft/lb and the 50/50 blend of 91/100 octane is putting out 385 hp and 406 ft/lb. As you can see, with the addition of just a few parts, the car has really waken up. The use of E85 allows a tuner to be much more aggressive with timing and boost.
