The PRBs raced with the CAMS NSW Motor Race Championship categories at Wakefield Park on
September 20-21, and some very close finishes were the result. Going in to the round, Chris Barry
was leading in the Series pointscore by a small margin from Stef Versluis and Stuart Shirvington, and
all three runners needed a good weekend to stay in the hunt.

Practice and qualifying
The weather for the weekend was fine and dry, and the track was fast. At the close of the qualifying session it
was Chris Barry on pole very closely followed by Stuart Shirvington, Stefan Versluis, and Tony Blanche. All of
these drivers were within one second of each other. In Class B, Trent Shirvington was a clear leader over
Joshua Versluis, and not far behind some of the Class A cars.

The schedule for the race meeting was generous with track time, with the number of laps to be 16, 14 and 18
for the three races. This would test the general fitness of the drivers and their cars.
Race 1 (16 Laps)
The first race proved to be very exciting. At the front of the race, Chris Barry got a clean start from pole, but
by the end of the first lap, Stuart was in the lead. Chris regained the lead in the following lap and thereafter
was not headed and went on to win. However, he was chased very closely all the way by Stuart and Stef
Versluis, and after 16 laps they were less than one second behind. Stuart registered the fastest lap in the race.

Further back there was a lot of excitement. Tony Blanche and Jos Kroon got past James Dick on the second lap
into fourth and fifth place. Ivan pulled into the pits after three laps, as his car seemed to be off song. Tony
opened up a gap and continued pretty much on his own, until he pulled off into the pits with one lap to go.

Jos continued to lead the following bunch, closely followed by Malcolm Lee, James Dick and Trent Shirvington.
All was well until the tenth lap, when Mal's car suddenly lost power in the fish hook corner, forcing those
behind to go in all directions. Because Jos was ahead of Mal, he was not troubled and went on to take a good
fourth place. Trent spun off the track and was well in last place before he got going again. As a consolation,
he registered the fastest lap for Class B.
All this drama brought out the yellow flags, which were still waving when Chris and Stuart arrived pretty much
side by side. This raised a question in a flag marshalls eyes as to whether Chris or Stuart was overtaking under
yellow flags, and Chris was called to the Stewards after the race to clarify that neither driver had in fact done
so. Mals's problem proved to be problem in the distributor that caused the engine timing to go right off.

Race 2 (14 laps)
Race 2 was the usual reverse grid race. There were only two class B runners in the form of Trent Shirvington
and Joshua Versluis and the intent was that they would get a 28-second start before the Class A cars started.
On this occasion the starters got the timing right, and Trent and Josh headed off while the others waited.
When the Class A cars started, Stuart Shirvington got a very good start from the back row, passing the other
Class A cars around the outside, and was the leading Class A car at the end of the first lap, followed by Jos
Kroon and James Dick. Trent was driving well at the front and slowly opened a gap over Josh.

On lap 6, Malcolm Lee retired with a problem, as his car went off song. It was found that a grub screw on the
throttle body had disappeared, allowing air to by-pass the butterfly on cylinder four.

At the front of the Class A cars, Stuart was driving really hard trying to catch his brother. He succeeded in this
with one lap to go, and went on to take the race win. Trent held on to take second place, 4.6 seconds ahead of
Chris Barry, who was 2.2 seconds ahead of Stef Versluis. Joshua Versluis was fifth ahead of all the other Class
A cars, and registered the fastest lap of Class B. Chris Barry got the fastest lap of Class A.

Race 3 (15 Laps)
The laps for this race were reduced from 18 to 15 because of a delay in the race schedule following an injury to
one of the HQ Holden racers. The grid positions for race three were based on the finishing positions from race
one. So it was Chris Barry on pole and Stuart Shirvington alongside.
Chris led off, but Stuart managed to get past on the first lap. Then it was a close tussle for the next four laps,
with Chris threatening and Stuart driving with both elbows out. Then on the sixth lap, Stuart tried too hard
and spun out on Turn 2. The left Chris in the lead, and he went on to take the win and fastest lap.

A close start to Race 3
Behind these two, Tony Blanche and Stef Verluis were very close all race with Tony mainly leading, apart from
lap 11 when Stef briefly got past. So Tony finally finished second just 0.2 seconds ahead of Stef. James Dick
was fourth, ahead of Stuart Shirvington, who had recovered from the rear of the field after his spin. Then it
was Jos, Ivan and Joshua. Joshua Versluis achieved fastest lap for Class B just ahead of Trent Shirvington.
Trent had pulled off the circuit after 7 laps with oil leaking from below his engine, and Malcolm returned to the
pits on lap 14, with his engine down on power.

The Wrapup
Of the Series contenders, it was a good weekend for Chris Barry who scored two firsts and a second in Div A;
although his Series total looks good for a Series win, he has to drop the pointscore for his worst 3 races which
brings Stuart and Stef much closer, as they have had an occasional problem this year and can drop rounds
where they scored low or zero points. The last column in the table above shows what the points would be if
there were only 5 rounds and the Series was completed.
However, there is still one round to go and all three drivers could win for 2014 after the Shannons Round
scheduled for November 1-2 at Sydney Motorsport Park.
In Div B Josh Versluis has been consistent all year, and his many class wins have ensured he will take out Div B,
but he does not have enough points to challenge the Div A leaders.
Driver of the Meetings was Chris Barry due to his consistency, his two wins and fastest
qualifying/ two race laps.
