The 78mm turbocharger has quickly become a favorite among single turbo V-8 enthusiasts, offering an affordable solution for significant horsepower gains across various applications. From single turbo setups pushing into the 9-second range to twin applications reaching the 8s, this turbo consistently delivers impressive results. Capable of supporting over 800 rear-wheel horsepower, the 78mm turbo excels in larger displacement engines, effectively managing back pressure for optimal performance.
Many comparable turbos on the market feature smaller 65mm or less exhaust wheels, severely limiting their potential. Our 78mm turbo boasts a larger 75mm exhaust wheel, perfectly matched to the 78mm compressor wheel. This strategic pairing allows for higher horsepower output while mitigating back pressure and preventing over-spinning. The result is an exceptional upgrade for those looking to surpass the limitations of smaller 65mm exhaust wheel turbos. In terms of price and performance, this turbocharger is unmatched.
