This has to be the loudest UPS truck we've ever heard. It's really important to notice during this dyno run how the hand held camera is shaking during one of the pulls. So it may not be quite as insane as the 2,200 hp quad turbocharged V8 we saw on Friday, but it's definitely more streetable, and has up to 100% more Dodge Viper GTS. This sucker is obviously set up for drag racing though following the advice of the video and going to UndergroundRacing.com gets us no additional info on the car. We did dig up pictures of the beast though, and its pretty sick. This almost makes us sad that the Viper is as good as dead these days. How much you want to bet these guys have already rented an oversea container to Poland?
