He Turned His Wife's Daily Driver Into A Grudge Truck! Crew Cab 4x4 Twin Turbo Silverado (Runs 9s)
What happens here
The heart of this drag truck is a meticulously built LS engine. Garry details the engine's specifications: a 5.3L LS block and crankshaft, complemented by robust Scat Rods and Wiesco pistons designed for an 8:1 compression ratio. Ported 243 cylinder heads and a BTR Stage 1 twin-turbo camshaft further optimize engine performance. This setup, combined with rear-mounted twin turbos, delivers impressive power, reportedly peaking around 7000 RPM at approximately 20 PSI of boost. The turbos and a custom intercooler (sourced from a boat) are strategically placed in the truck bed, along with a small fuel cell, all part of a "built out of junk" philosophy born from resourcefulness and tight deadlines for a race.
Goal: Achieve extreme horsepower and torque for drag racing through engine blueprinting and forced induction.
