Monoposto at Mallory Park, August 2010 – Race from Tristan Cliffe on Vimeo.

Not a good weekend really. Our problems started on Friday when the switch for the tail lift on the truck burnt out in the heavy rain, so we had to resort to touch wires together by hand to operate it. This was the first time we were going to use the truck at a race meeting, so we knew there were going to be issues related to it, but we weren’t expecting to have such fundamental failures… Oh well, you live and learn, and we can fix it in time for Oulton (which, at the time of writing, is only a few days away!).
At the circuit on the damp Sunday, I qualified in 3rd, missing out on the front row for the first time this year due mainly, I suspect, to traffic on the final two laps when the drying track was at its quickest. The ever present misfire reared its head again too, although I don’t think it’s costing much more than a tenth per lap (although that is no excuse). We are hopeful of getting the misfire problems sorted out, and we are attempting to discuss the matter with the people that made and mapped the ECU. However, a good race was still on the cards, until the throttle bodies failed for a second time in two meetings, leaving us with no throttle – the throttle shaft that links both throttle bodies together broke up. Clearly not strong enough, and a new design is in progress. Laughably, the throttle body manufacturer even tried to suggest it was the driver or the track that was causing their product to break. We’ve since offered to let them inspect the installation and the setup of the throttle cable before Oulton Park – although I’ve been triple checking the throttle cable and the pedal stops since Mallory last year.
Rounds 7 and 8 of the 2010 Monoposto championship are at Mallory Park, a track that so far seems to suit our Dallara, although I never felt especially comfortable there in the Reynard. This is probably because the Dallara is a much stiffer car, and remains more composed in long, high speed corners like Gerards.
Last year, it was our 2nd meeting with the car (we skipped Anglesey), and was the scene of our first victory and first pole position with the car – although Timms’ engine blow up removed an element of competition that weekend! However, the pole time was bang on the lap record, so I’m confident Jeremy would have had to work hard to beat it. Unfortunately, we also had a throttle cable failure in the subsequent race, and couldn’t capitalise on that form…

I was due to go to Mallory Park on the 14th April 2010 to assist Lenny Coleman, who purchased our championship winning Reynard 883 late last year, get used to his new steed, advising him on how to get the best out of the car, and to get the setup to his liking. Having someone on hand who knows the car, and how it reacts to various setup changes is a big help, and part of the Reynard sale deal was to be present at his first test.
However, as I was going, we decided that is wasn’t that much more effort or expense to take our Dallara with us and give it a brief shakedown test to make sure that the problems we suffered at Brands Hatch last month were cured. Leaving home at 5am was a bit of a drag, and confirmed for me why we now stay overnight at race circuits!!! The testing fee was also pretty reasonably, at £102, which made the decision is little easier to swallow…
MoreAnyway, Mallory Park… A double header weekend in the paddock that resembles Beruit on a particularly bad day, but we did get to camp next to one of three lakes situated inside the circuit. No swan attacks or even mosquito plagues, which is always a good thing. We arrived on Saturday evening, and whilst Martin, Andrew and I unloaded the car, awning and equipment ready for Sunday and Monday, Emma found a suitable spot for the tents and put them up. Before we knew it the car was safely in bed in the awning, and we were clambering into our tents hoping for some luck and some nice weather.
I awoke, as usual, quite a long time after the rest of the team, to the smell of frying bacon (and the taunts about mine going into the lake), and once fed and watered we got ready for scrutineering and signing on, both of which were fairly uneventful. At signing on we we asked to supply either £5 or a chocolate bar for a Marshals Fund, and as I didn’t happen to have chocolate on me had to cough up the fiver. At which point there was some entrepreneurial discussions about buying Mars Bars for 80p from the burger stands and selling them to unwitting competitors in the signing on queue for £4, thus making a healthy profit (a rarity in club motorsport). Sadly, none of us had the gumption (or the initial capital) to set up this business, which was a shame.
In just over a week we’ll be setting up camp in the wonderfully archaic paddock of Mallory Park for our second meeting of the year, rounds 5 and 6 of the 2009 Monoposto Racing Club championship.
For various reasons we were not able to attend the Anglesey meeting (rounds 3 and 4) – the event coincided with the anniversary of the death of my brother, and it would have been unfair on my parents to race on the same date when they worry enough as it is. But we’ve also had a few car problems (that we probably could have solved if we’d needed to) relating to the clutch release cylinder and the fuelling.
We’ve changed our clutch to a Superclutch one from the original AP clutch, which we hope will improve our starts and low speed driving in the paddock or assembly area. But the slave cylinder piston, which was seized when we bought the car (another example of the standard the car had been kept by the previous owner), was quite heavily scored. Whilst we sleeved it for Snetterton, it seems the fix was only a short term on. A proper fix has now been achieved by having the piston hard chromed and ground so the o-rings have a lovely surface to seal on. Fitting better sizes of o-rings should also help!
The fuelling is, we think, related to the high g-forces the car generates. At 2.5g, a figure we saw regularly at Snetterton, the fuel in the float chambers is assuming angles they were not designed to cope with, and we believe it’s causing the car to run lean. This usually manifests itself as a misfire out of the corner which isn’t good for corner exit speed. A number of fixes have been employed, but we won’t know how well they improve the situation until practice at Mallory.
