World’s quickest custom Subaru BRZ from Accelerated Performance

Accelerated Performance out of Toledo, Ohio claims to have the world’s quickest Subaru BRZ (sister car to the Scion FR-S and Toyota 86 / GT-86). Having run the ¼ mile in 11.3 s at 127 mph this Subaru BRZ appears to be the quickest BRZ / FR-S / Gt-86 in the world.

When Edmunds tested the Subaru BRZ they ran the ¼ mile in 15.3s at 92 mph. How does you lop a full 4 seconds from the ¼ mile and add some 35 mph? Answer: boost (about 20 psi worth) and alcohol (in the form of E85 fuel).

Rated at 200 BHP at the flywheel, a stock Subaru BRZ 2.0-liter flat-4 lays down around 165 WHP (wheel horsepower) on a chassis dyno. Accelerated Performance’s custom BRZ recorded 440 WHP on a Dynapack dyno.

The modifications required to more than double the power are pretty straightforward. Click the links to see more information about these parts in the OctaneNation parts database.

The header is stock–the turbocharger is connected to it through an adapter where it sits behind the engine. A bigger turbo would necessitate a custom exhaust header, greatly increasing the cost and complexity.

A car that runs on E85 is not a viable option for everyone but it does show what’s possible at lowish boost settings. Similar performance could be obtained with a methanol injection system, or a proper build with lower compression pistons on gasoline. The untouched longblock implies they are still running the stock 12.5:1 compression ratio.

Fueling is controlled by a stock ECU combined with a EcuTek Racerom.
