When it comes to pushing boundaries and setting records, Jeff Hagaman's 2011 Cadillac CTS-V is a shining example. Crafted by Hot Rod Dynamics in Lenoir, North Carolina, this beast was designed to dominate 1/2 mile racing. The journey began by swapping out the factory supercharged 6.2L LSA V8 for a custom-built 427ci (7.0L) LSx V8, engineered by Tim Lynch.

The goal was clear: generate over 1,500 horsepower at the wheels. This monumental task was achieved with the help of two Precision 7274 turbochargers and a sophisticated Holley Dominator engine management system. The power is funneled through an RPM TR-6060 six-speed manual transmission, ensuring every bit of that massive output is effectively transferred to the pavement.

To handle such colossal power, the rear of the CTS-V was completely re-engineered. Hot Rod Dynamics built a custom back-half featuring a four-link rear suspension, a Mark Williams third member, and Hi-Torque axles. This setup not only manages the power but also ensures optimal traction and stability at high speeds.

The results of this extensive modification were immediate and impressive. On its first outing, Jeff Hagaman set a world record by hitting 190.35 mph in the half-mile. With further tuning and practice, there's no doubt this Cadillac CTS-V will continue to shatter expectations and records alike.
