Butler Perrformance V-8 Engine Build - High-Tech, Lightweight, and Ready to Take on the World
The Turbos are fed by one-off headers designed and built by Travis Quillen at Young's Performance. They use a 2-inch primary and a 2.5-inch collector. Though the collector size sounds a bit small, it was purposely built that way to increase exhaust gas velocity to quicken the response of the turbos and build boost quickly. Rodney says that the flow is not restricted by the smallish collectors; the turbo is the only restriction in the exhaust tract. The ignition system consists of an MSD 7AL3 connected to a four-stage boost controller. It works on timers to control boost during every phase of the run. MSD 50-ohm/ft plug wires and NGK 5671-10 plugs round out the system. View Related Article
