2019 Cadillac CTS-V Supercharged LT4

Cadillac | CTS-V : March 13, 2020

Brian brought us his 2019 Cadillac CTS-V for the first round of modifications!

Up first, John strapped her down for some baseline dyno runs to establish our starting point (coming in at 576.90whp & 633.52lbft), then next up the shop, Thomas set the LT4 up with a Roto-Fab, LLC air-intake system, GripTec 2.30″ upper supercharger pulley, a Mightymouse Solutions Mild catch can, Stainless Works 2.00″ primary OD long-tube headers Cerakoted by Detective Coating, MSD Performance spark-plug wires wrapped in Design Engineering, Inc. Protect-a-Boots, C&R Racing 27mm core heat exchanger, and a Lingenfelter Performance Engineering 160° thermostat.

With the mechanical work wrapped in the shop, John strapped her back down for Vlad to perform a custom calibration via HP Tuners. The results? 652.99whp & 668.75lbft on 93 octane, a gain of 76.09whp & 35.23lbft over stock baseline! Killer results for the first round of work, with more to come in the future.
