    • USP Motorsports B5 A4 1.8T hits an impressive 458 wheel horsepower with an upgraded turbo on E85

      Ah the venerable Audi 1.8T. A relatively small turbocharged four-cylinder but easily upgraded and can definitely put out good power for its size. Here is a great example with a 458 wheel horsepower and 390 wheel torque example. USP Motorsports modified this B5 A4 1.8T with a Precision 5857 turbocharger, E85 fuel, and Eurodyne engine management. After custom tuning on a Dynojet the result is what you see in the video below.
