Overdriving


It's easy to be excited about getting a new toy, harder to remember that there is work to do.

Jon and Dean Crooke have been working like Hebrew slaves in Egypt to prepare up to 6 karts in time for the launch of season 07. Exacerbating the workload was the banning of fibreglass sidepods for Rotax Max, which was no doubt done in an effort to prevent the sport appearing too professional and sophisticated.

Still, Jon and Dean, those pesky rebels, are determined to make their karts more attractive than something you pick up at a garage sale. So, they endured a flurry of experimental plastic moulding processes, not many of which produced a quality result.

Notwithstanding, a herd of HyperRacers hit Winton on February 9th for some sorting sessions.

My mistake for the day was expecting the Hyper Racer to make me a better driver. I spent a session and a half gyrating wildly with snap oversteer, including some major tankslappers on the way out of bumpy turn 10 (onto the V8 Supercar Pit Straight).

When this happens the automatic reaction is to make "panic changes" to reduce front grip or increase rear grip. Eventually we calmed down and realised two things:

Firstly, pitting next to us was Aus-Superbike champion Adam ‘Krusty’ Fergusson of team DVS Honda. They have loads of data on Winton and he told us that, with a track temp of 58 degrees, the grip levels were hopeless (although his wording was somewhat more emphatic).

Secondly, I learned to drive in an ageing chassis with uneven handling. I had basically taught myself to turn in a little early, trail-braking up to the apex with fistfulls of steering input.

The Hyper doesn't work that way. The steering is very, very light. The inputs have to be subtle. It rewards smooth, fluid driving. Whilst it's fun to play with Schumacher-style aggression, manhandling the machine up to the corner with mega late braking, sometimes you have to return to the textbook.

After spin number...well, I forget how many I had, the former National Formula 2 Champion and Group A Touring Car Endurance driver told me to "stop over-driving". You're never too old for some coaching. It worked.

There were some nasty vibrations, partly from poor front wheel balance with our new brand of tyre, and partly because I had destroyed the brake disc from sliding over kerbs backwards.

Apart from that, I got the hang of this new toy, and it was a joy.

Former Rotax World Masters Champion Mark Wicks, in Dean's '06 chassis, played around on old Dunlops setting some rapid times. I was faster but only as much as I should have been, considering Mark was properly ballasted for Rotax heavy. I was still running au naturel weight. So, all the key indices seem to suggest I am on target. Mark and I spent the rest of the day arguing over who shouldn't be called "Rubens". I dont mind finishing behind someone who is better than me, so I can think of worst things to be called.

To be realistic, and slightly the pessimist, I expect to be no quicker than the old kart on a (very) good day, but much more comfortable.

An optimist would suggest otherwise.
