Well, here it is barreling down the highway, with its pair of turbochargers whooshing away while its supercharger whines.
In case you’ve forgotten, the Challenger SRT Hellcat X is a one-off project car from Dodge, built for the folks at Dream Giveaway. They give away two cars at a time (one old, one new) via a raffle draw, with proceeds from the ticket sales donated to charity.
The winner of the crazy Challenger was 71-year-old Dennis Daly of Folsom, California, who ended up buying $110 worth of tickets. He took delivery of the car along with a 1970 Dodge Challenger R/T back in July, but not before Dream Giveaway could show off the car’s performance. You’ll want to turn your speakers up before hitting play.
The likely answer is that the car is running a simpler “series” setup, with the turbocharger outlet feeding into the supercharger inlet. With the stock supercharger being designed for air at atmospheric pressure, the turbos are likely tuned to deliver very mild boost pressure in order to preserve the supercharger and other engine parts.
