Do you hear that whistle?
When it comes to pulling pranks on truck fans, the guys at Armageddon Turbo seemed to have mastered the art. These guys took a brand new 2015 Silverado 1500 and secretly installed an aftermarket Armageddon Twin Turbo system in the truck before taking it in to a Chevy dealer for a service appointment. The Twin-Turbo system is an alternative to supercharging systems and apparently boosts the power in 2014+ GM 5.3L and 6.2L engines to as much as 1200+ hp.
The truck in this video has the 6.2-liter V8 engine and is tuned to make 650 hp at the crank which is 200 hp more than the stock output. Can you guess how the guys at the dealership reacted when they went for a test drive after being told that the truck was making a strange whistling noise? Keep in mind, the truck looks completely stock and is a total sleeper.
