The 2021 model year will bring with it a last-breath update for the current-generation Dodge Durango SRT, with a major addition to the lineup: a new SRT model powered by none other than the supercharged, high-output 6.2L Hellcat V8.

But that model has been in the pipeline for some time now. What if you just can't wait a moment longer? Well, we suppose you could build your own.

One group did just that - sort of. See, instead of just dropping a complete Hellcat motor in a 2018 Dodge Durango SRT and calling it a day, Vector Motorsports modified the bejeebus out of the factory 6.4-liter Hemi V8 and strapped a ProCharger blower onto it.

That choice of supercharger supplier is a notable one, because where the Dodge SRT Hellcat motor uses a positive-displacement twin-screw supercharger, ProCharger specializes in centrifugal-style blowers - superchargers that look sort of like the compressor side of a turbo, but that are driven by belts instead of exhaust gases. Centrifugal superchargers don't tend to have the same immediacy as twin-screw or roots-type blowers; they really need to get spinning before they make any serious boost pressure.

Even still, they're capable of making monster power - up to 615 horsepower at all four wheels, in the case of this Dodge Durango SRT. That's likely well north of 700 crank horsepower.

To make the most of the extra oomph, Vector Motorsports further modified their 2018 Dodge Durango SRT with a full Motion Control Suspension, two-piece brake rotors, and track-savvy wheels and tires. To cope with the extra stress introduced by the supercharger, the engine features a built block with forged VMS rods, pistons, and crank, an upgraded fuel system, and some very open-sounding headers.

This ripping three-row SUV was built for the now-canceled 2020 Tire Rack Brock Yates' One Lap of America, but even though that event had to be called off, the One Lap Eh Team seems to be getting some good use out of it.
