HOW TO BUILD A MARCH 83G
CHAPTER 10

Оглавление

In those days, every motor racing team effectively had three engineering disciplines: the design and aerodynamics offices, and race engineering, though the race engineers would be doubling up with working in the design office during the week.

Since then, the industry has mushroomed, and nobody crosses from one department to another. You’ll have, let’s say, 90 people in aerodynamics, another 70 in the design office, and perhaps 30 in race engineering and simulation, the latter being a relatively new area.

Me, I’m known chiefly as an aerodynamicist, but that’s a product of the fact that aerodynamics is the biggest single performance differentiator. Therefore, I tend to spend most of my time looking at aerodynamics, with the mechanical layout a close second, in order to make sure the two complement one another in a package. In fact, my sole interest lies in improving the ability of the car to score points, and what helps me do that is my experience across the disciplines.

Which brings me back to early 1982, when of the three key areas – aerodynamics, mechanical design and race engineering – I only had experience of the first. With Fittipaldi I had been loosely involved in the design of the rear suspension for the axed 1982 car, but not in the detail. I’d been to the track a grand total of once, and that was for a cold test at Donington where I just stood and watched the car do a few shakedown laps. I’d never even worn a set of headphones.

At its simplest level, what a race engineer does is work with the driver to get as much performance from the car as he can. It incorporates basics like issuing instructions to the mechanics on how much fuel to put in and which set of tyres to fit for each outing, as well as ensuring that the set-up is correct depending on the conditions: the weather, of course, but also the track.

The tools the race engineer has at his disposal are what we call the set-up parameters: that’s the front and rear spring rates, the roll bar stiffness, the damper settings, the wing settings, the ride-heights, the camber, caster and toe-in or toe-out of the wheels, gear ratios, etc. It’s all about trying to find the right set-up for the car, the driver – each driver has his own race engineer – and the circuit.

What attracted me to race engineering, besides the chance to learn something new, was the opportunity to combine that with being a designer and an aerodynamicist. I could influence the development of a car based on first-hand knowledge of its performance at the track.

So say, for example, the driver was complaining of a handling problem. In the first instance I could talk to him in a race-engineering capacity and perhaps reduce the problem through the set-up of the car. But with an engineer’s eyes I could also hope to understand whether that problem was inherent to the mechanical design or the aerodynamic characteristics of the car. My understanding of the car would be complete.

So when Peter Mackintosh, having left Fittipaldi to take charge of the March Formula Two team, offered me a job, and that job was the chance to work as a race engineer at the weekends, then in the drawing office during the week as a draughtsman, I was sorely tempted, and probably would have signed immediately if not for the fact that Peter Warr offered me a post at Lotus as an aerodynamicist.

Now I had some real thinking to do. Should I stay in Formula One and go to Lotus, ‘my’ team? Or should I take the opportunity to learn the two missing disciplines in my CV at March, albeit with a drop to the lower categories?

In truth there wasn’t a huge amount of deciding to be done. You might say I’m lacking in sentimentality, but I prefer to think of it as taking a clear-eyed view of the future. I really wanted to add that race-engineering-and-design-draughtsman string to my bow. I chose March.

I began work. Feeling awfully wet behind the ears, and only too aware that I’d be race engineering drivers a few years older than I was, I grew a beard. Peter Mackintosh, the team manager, with no engineering background but lots of experience, was race engineering Corrado Fabi, while Ralph Bellamy, the Aussie veteran engineer who designed the Formula Two car, engineered Johnny Cecotto. I was given the third car, driven by Christian Danner.

My first race of the Formula Two season was at Silverstone, on 21 March 1982. And it was straight in at the deep end, having joined too late to attend any of the pre-season tests. It was raining, so I saw to it that the wet tyres were on and correctly pressured, and I made sure that there was fuel in the car. Simple stuff, I know, but I wanted to at least get through the weekend having got the basics right.

Christian took the lead. He was good in the wet, and he was leading the race with two laps to go when, to our horror, he drew to a stop. His car had run out of fuel.

I got the blame. Christian ranted that I didn’t know what I was doing (partly true), and that I was useless (objection, your honour), and with emotions running high, before he was in possession of all the facts, Christian fired me as his race engineer.

I would later be absolved – it turned out there was a leak – but the damage was done; our relationship was terminal after that first weekend and it appeared my race engineering was, at the very least, on temporary hold. However, to my everlasting gratitude, and for reasons that I have never understood, Johnny suggested we do a swap, with Ralph engineering Christian, and me learning the ropes with Johnny.

Johnny was a cheerful, curly-haired Venezuelan; a real character. He was already a world champion in motorcycle racing, but after some distressing accidents had moved into racing cars. His plan was to prove himself in Formula Two with the aim of progressing into Formula One. That being the case, taking on an inexperienced race engineer was something of a gamble.

But that’s the kind of chap he was; on one occasion he’d noticed that the silencers on my Ducati were rusty and he used his contacts in Ducati to get me a new set. He just had that in him, and I owe him a great deal for giving me a second chance.

What’s more, he was a great driver, and as the season wore on he won at Thruxton and remained competitive for other races. Meanwhile I concentrated on finding my feet, as well as developing an understanding of Johnny and gradually changing the set-up of the car to suit his driving style.

In its simplified form, the essence of motor racing is to link together as quickly as possible the sequence of corners that form all racing tracks. However, all drivers have subtly different styles and all racing cars have different inherent characteristics; changing the set-up is a process that involves customising the car to the individual driver and finding the best relationship between the car and the style of the driver. This involves tweaking the ‘set-up parameters’ mentioned earlier.

As far as springs went, we worked to a system evolved by Ralph: 1600lbs/in on the front and 1500lbs/in on the rear, which was a fairly stiff set-up that we ran on all three cars.

Until, that was, we got to the seventh race, at Pau in the South of France, a street track. Johnny and I walked the track. ‘Christ,’ I said, ‘this is a bumpy track. I think we need to go soft on the springs; get a bit more compliance in the suspension. What do you think: fit the softer springs now, or wait until after the first session?’

Johnny had faith in me. ‘Straightaway,’ he said.

So I went and had a rummage in the truck, found some soft springs and fitted them, taking it down 200lbs/in each end.

The benefit of doing this, of course, is that the car will absorb the bumps more effectively. With stiff springs on a bumpy track, the car tends to leap from bump to bump, meaning the load on the tyres at the contact patch changes too much, causing the car to continually grip and slide between crest and hollow. If you’ve ever driven an overly stiff road car, you’ll know what I mean. You go over a pothole, get shaken about, the car skitters. However, the extra compliance in the softer springs means that the car will change its attitude more, pitching under braking, rolling more in the corners and sinking more as the downforce comes on with speed. This extra movement of the car upsets the aerodynamics with the downforce, and particularly the distribution of downforce between the front and rear axles, changing more than with a stiffly sprung car. It is all about finding the best compromise for a given car at a given circuit.

Johnny practised with the new springs, felt the suspension was still too stiff and so, with Ralph and Peter oblivious to what I was doing, I went and had a second rummage, found even softer springs and fitted those. And then, just in case Ralph and Peter cottoned on and decided to swap springs on their own cars, I hid the remaining soft ones.

With hindsight, that was a very naughty thing to do. Led astray by the lure of competition, I forgot I was employed by the team, not the driver. But Johnny went on to take pole and win the race, something I will guiltily admit was a hugely satisfying result, given the reflected glow for yours truly, and one that perhaps went some way to repaying Johnny’s trust in adopting me.

Towards the end of the year we had three consecutive races in Italy; in Mugello, northern Italy, then Enna in Sicily and finally back up to Misano, which is on the Adriatic Coast. Flying wasn’t so common in those days; we, the mechanics and I, just drove from race to race, and for three weeks we enjoyed a fabulous tour of Italy. Prior to that I’d never travelled further than Scotland; now here I was taking in the Mediterranean sights. We stayed in Rome one night; we took the ferry across to Sicily. It was fabulous.

The Enna race was stinking hot. We all ate watermelon – and all went down with the squits. The theory was that it had been grown in sewage. All I knew was that the whole team was in an awful state for race day, particularly those of us who were working on Johnny’s car – to the point that we managed to get him started and then ran off to sit on the loo for the whole race. If he’d had a problem, he would have had to sort it out himself, because there was nobody in the pits any more!

But apart from that, it was a fabulous season. What’s more, I was learning on the job and proving myself as a race engineer, as the battle between Johnny and his teammate, Corrado, was hard-fought and went right to the wire. And though Corrado won, Johnny’s second place in the championship earned him a spot in Formula One for the following season.

With all that going on, I was also having fun at the drawing board during the week.
