The Austrian Tuner O.CT Oberscheider Tuning (www.oct-tuning.com) presents a new engine upgrade for the Seat Leon Cupra and VW Golf GTI. The standard output can be increased from 200 and 240 horsepower, up to 315 horsepower.

Stage 3 of the O.CT Tuning engine program includes an ECU upgrade and a moderate increase in boost. When combined with the sport exhaust system and racesportcat, the Golf GTI output rises to 270 horsepower, while the Leon Cupra cranks out a whopping 315 horses.

Extensive modifications to the fuel injection system and the air intercooler are a part of the engine upgrade. The O.CT intercooler kit is installed in addition to the stock unit. The result is an improvement in air cooling, which is particularly noticeable in the higher rpm range, where the stock intercooler alone is operating at maximum capacity. The kit also contains specially designed hoses. A special sport exhaust system including a racesportcat was designed especially for the Seat Leon Cupra and VW Golf GTI to reduce back pressure and exhaust temperatures.

The Seat Leon by O.CT Tuning accelerates from 0 to 100 km/h in 5,2 seconds (stock vehicle 6,2 seconds), challenging potent sports cars such as Porsche. Top speed is 265 km/h (stock vehicle 250 km/h). The values of the GTI are only close behind.

To maintain safety and stability even at these speeds, O.CT Tuning offers coilover suspension with various setups, 19-inch wheels and an 8-piston brake system with 372 mm rotors. A short-shift kit for the manual transmission is also available.

The 8,5 x 19 inch wheels with a 45 mm offset are available in Black Mate, Super Polished (as shown on the Seat Leon photos) and in Bi Color (as shown on the Golf GTI photos).

Under the hood, O.CT carbon platings for the engine, battery and air filter gives the technical components a sportier appearance.
