Five Of 2017’s Baddest Chassis Dyno Runs From Down Under!

We all know that Aussies love their horsepower almost as much as we do. To that end, Fullboost compiled a video of five of their favorite dyno runs from 2017, and surprisingly, they are a mixture of different engine sizes and configurations. However, they all do have one thing in common – they are all turbocharged, and all make big power.

The first vehicle featured is a Holden VK Calais which has had the original Holden V8 tossed in the bin (to use their vernacular) and replaced with a 388 cubic-inch LSX-based engine put together by the team at Powerhouse Engines. With 18 psi of boost pressure from a BorgWarner S484 turbocharger on board, the 275 radial-shod street car makes an impressive 812 horsepower to the rollers through a ‘Glide transmission.

Next up is a ’99 Skyline with a stock crank and a Precision 68/70 turbocharger. While that might seem unimpressive to begin with, the little 2.6-liter inline six is pressurized to almost four times atmospheric pressure to make a wild 841 horsepower. For those keeping track that’s more power than the first LS, with 2.5 times less displacement.

An even smaller engine, a Mazda 13B rotary, is featured next, which has an advertised displacement of only 1.3 liters from its two rotors. While the method of displacement calculation on a rotary is a topic of hot discussion, there’s no arguing the fact that this one makes over 1,000 horsepower on methanol, thanks to a massive Garrett GTX55 turbocharger cramming 47 psi of boost into the Wankel engine, while shooting flames higher than the roofline of the car at the end of its dyno runs.

The second-to-highest performer of the video is an interesting mix of parts. Starting with a Nissan RB30 block, a stroker crank brings displacement to 3.2 liters, then the engine is topped off with the head from an RB26 engine. Fueled by E85 ethanol and force-fed by an 88mm Precision turbo at 40 psi, the franken-engine makes a whopping 1,142 horsepower at the rear tires.

The big boy of the video is none other than a good-ol’ American Blue Oval V8 sitting in an Australian Ford XW Falcon. The 427 Windsor uses a Dart block and a set of CHI heads to suck down boost from a pair of Precision 88mm turbochargers. Through a two-speed, the car puts down a whopping 2,052.9 peak horsepower at the end of its dyno runs.

While American V8s bookend the video, with Japanese engines taking middle three spots, it is quite interesting to see the different turbocharged combinations making serious horsepower when tuned by Australian hands. It’s nearly five minutes of chassis-dyno insanity…check it out!
