Open Class: PSR Tuning Evo 7

Another familiar car at World Time Attack is the PSR tuning backed Evo 7 of Duncan Shiu. This car finished just off the podium in Open Class in 2011 in the hands of George Whenn with Duncan driving the ex- Autoselect GTR.

With the competition stiffer than ever Duncan has spent the past year refining what was already a potent package with wider Fenders, wider tyres and a more refined engine combination.

The engine is a complete Tomei 2.2 deal with oversize valves and solid lifters. The turbo is a custom made Garrett GTX3582 with a HKS 60mmm GT2 wastegate and a 100mm titanium TITAN exhaust. The ECU is a top line MoTeC M800 with a Racepack dash. This setup has proven more than reliable and is continually being refined for “usable” power which equates to faster laps times. An Evo RS 5 speed box fitted with OS close ratio gear set and a ORC twin plate clutch. The diffs are by Ralliart and Kaaz and both the front and rear sub frames are lightweight versions.

Underneath are a set of TEIN Super racing Coil overs that hang off a full set of Nagisa arms front and rear and much time has been spent perfecting the suspension geometry on this car. The sway bars are by Whiteline.

The theme continues with the brakes with a set of topline Brembo monoblock calipers and Performance Friction discs and a full custom made pedal box. The tyres are now the fattest Hankook Ventus Z221 available in 295/30/18 size.
The bodykit is now a full Cyber Evo Voltex deal and Duncan will be out to put it to the test in August, with the fast sweeping Eastern Creek circuit favoring the aero cars without question. Nik Kalis certainly set  the benchmark time in 2011 but there is no question that many will be knocking on his door this year and Duncan would like to be one of them.
