7875 T4 Turbocharger

The On3 Performance 7875 T4 Turbocharger has become a popular upgrade for V-8 engines seeking enhanced performance, offering a balance of affordability and high-horsepower capability. It is designed to support over 800 rear-wheel horsepower, making it suitable for larger displacement engines where managing exhaust back pressure is crucial for optimal performance. This turbocharger features a 78mm compressor wheel on the cold side with a .80 A/R and a 4-inch inlet with a 2.5-inch outlet. The exhaust side boasts a 75mm exducer with a T4 flange and a .96 A/R housing, featuring a 3.0-inch V-band outlet. This combination, particularly the larger 75mm exhaust wheel, is a key differentiator from other turbos in its class which often use smaller 65mm exhaust wheels, allowing for increased horsepower potential and better control over turbocharger speed. On3 Performance highlights the reliability and power potential of this turbocharger, noting its use in both daily drivers and performance vehicles. For instance, their own 2002 GT, equipped with a smaller 70mm unit, has accumulated over 20,000 miles of daily driving and track use. To ensure the longevity of the turbocharger, the manufacturer recommends using a 1/8" feed line and a 5/8" return line, emphasizing the importance of proper sizing to prevent damage. This turbocharger is presented as a significant upgrade for those already maxing out On3's 76mm turbocharger with a 65mm exhaust wheel. The company claims to offer superior value at its price point compared to other options on the market.
