The 2009 CTS-V marked a significant leap forward for Cadillac, injecting high-performance DNA into their luxury sedan lineup. For enthusiasts seeking to push the boundaries even further, the aftermarket offers a treasure trove of upgrades. This article delves into the journey of modifying a 2009 CTS-V, transforming it from a potent stock machine into a true drag strip contender, all while maintaining its street-driveability.
Initially, even with minimal modifications, the 2009 CTS-V showcases impressive potential. Equipped with just an A6 transmission with a 2.55 upper pulley and an 8.6 lower pulley, ID850 injectors, E85 fuel, and a tune by Formato, this car achieved a 10.49-second quarter-mile at 133.6 mph. Remarkably, these results were obtained on stock factory rims, drag radial tires, stock exhaust manifolds with hollowed catalytic converters, a stock heat exchanger, and without any weight reduction. The 6.2L supercharged V8, even with these bolt-ons and running on E70 fuel in hot, humid conditions, dynoed at a formidable 624 whp and 640 wtq on drag radials. This setup demonstrates that even with basic upgrades, the 2009 CTS-V’s robust foundation allows for substantial power increases and track performance improvements.
Pushing the envelope further, the next stage of modifications involved more significant internal engine work and supporting upgrades. Formato heads, a BT3 camshaft, a Formato ice tank, a Varimax pump, and comprehensive porting – including the cylinder heads and supercharger – were installed, again tuned by Formato. This more aggressive setup, still running on E85 (E72), resulted in a dyno figure of 747 whp and 730 wtq on drag radials. At the track, this transformed the car into a sub-10.1-second machine, achieving a best of 10.08 seconds at 139.5 mph. Even with a less-than-ideal 1.51 60-foot time due to tire spin on stock 19-inch wheels with MT SS tires and E68 fuel, the car demonstrated its immense potential. Notably, these runs were still conducted with no weight reduction and with the car driven to the track in street trim, emphasizing the “run it like I drive it every time” philosophy.
These real-world examples highlight the incredible capability of the 2009 CTS-V platform. From simple bolt-ons to more extensive engine modifications, the car responds exceptionally well to upgrades, delivering consistent and impressive performance gains both on the dyno and at the drag strip. For those looking to maximize the potential of their 2009 CTS-V, these modifications serve as a testament to what’s achievable while retaining the car’s street-friendly character.
