With our turbo in place, we configured the Procharger air-to-air intercooler.




Of course, a turbo LS motor is no good without a turbo, so we set up the 6.0-liter with a system capable of making plenty of power. Starting with a pair of stock truck manifolds, we reversed them, then joined the exhaust using a custom 2.5-inch Y-pipe from JFAB. The Y-pipe was built to accept any turbo flange using a 3-inch v-band adapter. We installed a T4 flange for this testing. The Y-pipe also featured provisions for a pair of TurboSmart, Gen-V wastegates and a single pressure sensor to monitor back-pressure before the turbo. The boost was supplied by a single BorgWarner S480 turbo that featured a billet 80mm wheel. Capable of supporting over 1,200 horsepower, the S480 also featured a standard compressor housing, a 92mm turbine wheel, and 1.25 AR exhaust housing. The boost was fed through a high-flow, Procharger air-to-air intercooler with 3.5-inch inlet and outlets. The discharge tubing also featured a single Race Port blow-off valve from TurboSmart. The Nitrous Express N-Tercooler, was installed onto the front side of the intercooler core to allow the dedicated fan to help blow the nitrous through the core.

The discharge tube also featured a Race Port blow-off valve from Turbosmart.


All that wonderful boost was fed through a Dorman LS6 intake manifold from Summit Racing. Note also the Wilson fuel rails and Holley 120-pound injectors.
