Pop your hood, bro

If there is one thing that divides the fans of the Demon Energy D1NZ National Drifting Championship more than any other, it’s the engine choice — V8, RB, JZ, SR, rotary? You can’t sit on the fence, so choose your side!

Walk pit lane at any round of the Demon Energy D1NZ National Drifting Championship and you will not only be greeted by a wash of colourful liveries fighting for your attention — dig a little deeper into the engine bays of the beasts, and you will find a weird and wonderful array of solutions to the same exact problem. Following the worldwide trend/evolution over the past 13 seasons of our national series, power figures have continued to rise, now reaching extraordinary levels. This season, the average power for a Pro-spec car is 471kW, which is why drifting is touted as being the most powerful tin-top motorsport on the planet. Now we’re past the midway point of the season, we decided to take a closer look at the power plants of the front runners. What we found surprised us, as, unlike series overseas — which tend to see not much other than the mighty LS — back home in New Zealand, we do things a little differently and have a wide range of engine choices in our current top 10.

Current D1NZ Pro field engine percentages:
LS: 23.31%
RB: 43.29%
2J: 19.98%
Rotary: 6.66%
1J: 3.33%
VQ: 3.33%

Past DK championship winner stats: 
RB — four times
V8 — three times
SR — four times

Total Pro championship power for 2017: 13,193kW

Average power output for 2017: 471kW
