More E85 Magic at COBB Tuning!

E85 Stage2 STI

The corn juice junkies at COBB Tuning Plano wanted to see just what kind of power could be made on an mostly stock STI with just the addition of E85. The test car was a 2005 STI with a stock turbocharger, a turboback exhaust and a high-flow intake. In order to run E85, the fuel system does need to be upgraded and to that end a set of Deatschwerks 850cc injectors were installed, along with a Walbro 255lph fuel pump.

The end results were impressive, 350whp and 412lb/ft of torque! E85 not only cools the combustion chamber allowing tuners to run more timing, but it also carries much of it’s own oxygen into the combustion chamber allowing the production of more power, it also is the equivalent of 105 octane gasoline, again allowing the tuner to be more aggressive with the tune.

The STI was tuned with a COBB Tuning AccessPORT and thanks to the AccessPORT’s ability to carry multiple maps and easily switch between calibrations with the press of a button, this STI is a true flex-fuel car and can be run easily on both gasoline and E85.
