Roush Mustang GT605

500 horsepower under the hood may have been impressive back when Ford and Shelby launched the Shelby GT500 last year and is still nothing to be sneezed at but with more and more cars hitting the 600 hp mark Roush and FRT (Ford Racing Technologies) set out to rectify the hp output. Jack Roush was impressed with the 500hp 5.4 liter V8 found in the Mustang but said: “We thought we could get a little more out of that engine.” And a little more it is, little meaning 105hp!

The additional 105hp are achieved through the new Ford Racing GT500 Supercharger which uses a new TVS roots-style technology improving both airflow and efficiency, where more airflow means more power. This supercharger is the first to use this new technology both in the OE (original equipment) and aftermarket segment. The cold air intake kit considerably reduces pressure drop across the stock air box and filter element. It comes with a high-flow, large 6-inch conical filter and the rotomolded airbox seals to the hood to reduce leakage.

The power boost can be yours for just USD 5,600 from either Ford Racing Technologies or Roush and does not affect the 1-year/12,000 mile drivetrain warranty warranty.
