Within the WTAC event there are specialty classes. In 2014 this was the R35 GTR class.

Due to the insane power this new breed of Demo car is making, in excess of 1000 hp, the event organisers decided to give these machines a class of their own to compete against each other.

 The ‘Big Dogs’ rocked up such as HKS and Top Secret, utilising Professional drivers like Nobuteru Taniguchi and Eiji ‘Tarzan’ Yamada.

 The cars were going hard around the Sydney Motorsports Park track, but it is easy to come in too hot to the first hard corner after the main straight, even for a pro like Nob.

As well as the cars on track, there are many vendor stalls with demo cars on display.

The variety of display cars and companies was vast, with everything from Ferrari’s to Datsun 1600 wagon’s on show.

The Individual Throttle Body (ITB) setup on this 1600’s 4 cylinder was quite delicious.

Using rotary engine’s in certain configurations, often allows for a large amount of available room within the engine bay, as shown on this 13B powered RX7 S6.

It is worth noting the blue rectangular decals found on various components were actually a temperature gauge, to keep an eye on component temperature within the bay, very clever.

The full carbon body on this Toyota MR-S from Carbon Plus was overkill, but in the best possible way, such an under-appreciated light weight vehicle, now made even lighter.

The MR-S was in good company on the stand being placed with its Evolution X Mitsubishi lancer counterpart.

A car often seen at events down here in Melbourne, the vehicle seems to be in an ever evolving state.

A very aggressive street car.

On the other end of the spectrum we have this JETT Racing Mitsubishi Eclipse drag car, running a 4G63 with Billet block and engine sized turbo.

More rotary action, this time in Naturally Aspirated (N/A) form, the custom 4 rotor utilising an Injection Perfection ITB setup with outrageous velocity stacks, to provide as much audible bliss as possible. 2015 was truly the year of the quad rotor.

This tidy rig rolled by us on the way in, From Autohaus in Sydney, it was so nice to see a classic porsche in such good condition.

The braking was certainly serious.

Then there are the truly special vehicles that are flown in especially for the spectators.

Vehicles like this F1 Renault v6 powered, flame pumping Peugeot 206 WRC rally car, which put on a show for everyone.

But not many cars on this earth can match the mystique and prestige of the factory built Mazda 767B race car, built to compete at Le Mans for Mazda.

The 767B was powered by the first incarnation of the quad rotor the 13J-M making 450 kw (600 hp)

Watching it drive around the track on two seperate days was a real treat, and the fans certainly appreciated it.

Everytime the car was heard nearing the main straight, the whole crowd went quiet, listening in awe at the beautiful sound from the first of the quad rotor engines flying down the straight and onto the brakes as it entered the first corner, dumping flames and igniting the atmosphere with sound.

What a masterpiece.
