Pembo- NEw Brighton Stages, Action ShotNew Brighton Promenade Stage - Wirral 7th & 8Th September 2012

It has been several years since I have competed in this rally and thought that a return to the closed public roads was overdue. 2001 saw the 30th anniversary of the event and a special ‘one off’ super special stage was organised. This saw two cars start together and complete two laps of the stage. This made it quite entertaining for the spectators and the drivers too. The super special stage was such a success that they decided to run a longer version of it in 2012 on the Friday evening.

The 2012 event was fully subscribed to within 3 weeks with over 110 cars wanting one on the 90 places. Held over 2 days the area welcomed crews and spectators from all over the country to a unique driving challenge of closed public road 100% tarmac rally.

Friday was the usual noise and safety checks with scrutineering taking place on the Promenade for everyone to see. Roads are not closed until 16:00 so a drive along these public roads before they closed was in order. Any competitor found ‘testing’ prior to the event is instantly disqualified.

The Friday run was in reverse seeding order so car 91 and car 90 ran together for their 4 loops of the New Brighton waterfront. They were able to have their run in daylight starting at 17:15. I was seeded at car 41 which according to the schedule showed a start time of 19:52, just after sunset but enough daylight to drive without the lamp pod on. As with these events it only takes one accident or breakdown and the running order slides. I had not removed the lamp pod and made a decision to leave it on until we left the service area. We checked the time and sure enough we were on the start line at 20:25. Darkness had fallen and the lights were needed. A very disappointing run put us well down the field overnight! Lets hope for a better Saturday!

Before I go into the Saturday report I’d just like to tell people about the car. Some of you will remember the dark blue car, well that has now been weighed in at the scrap yard after a ‘small’ accident at over 100mph on Epynt Military ranges in Wales. This ‘new’ car, known as the red arrow, started life as a 10v quattro and was bought off Ebay for £400 as an MOT failure. Fully stripped and rebuilt from the salvaged parts from the ‘old’ car, plus a few new extras, the car has the following specification.

Previous car

Saturday:

Stage diagramSo onto Saturday! With 10 tough stages in front of us and the temperature rising from early morning it was going to a hot day, perhaps the hottest that the car had ever run in.

For those of you not familiar with the stage rally format, let me explain briefly. You have a strict time schedule to adhere to, so service time is limited and time controls at stage start, stage finish, service in and service out are all times to the minute. If you arrive early or late you get time penalties which are added to your special stage time. The special stages are timed to the second and fastest overall over all of the different stages wins the event. Quite simply, arrive on time everywhere, drive as fast as you can on the stages and then go home!

Stage diagrams are provided by the organisers just prior to the event start. These are roughly drawn sketches that the navigator has to interpret and read out to the driver in the form of instructions or ‘pace notes’. The more accurate these are, the better the driver can read the road and route that lies ahead. An incorrect route will give the crew a ‘stage maximum’ time which puts you way down the field.

 

From of lower than expected position after the Friday run we drove to be where we should have been, in the mid-thirties. The car performed solidly until stage 7 when for no known reason the car refused to tick over and started to cut out on the down changes. Coming into the roundabouts the car stalled with the engine cutting out. This dropped us down the rankings and we finished 48th overall.
