So what is the key for
fast hillclimb driving?
Where did you start in
hillclimbing?
I first
started in 1989 in a modified Ford Anglia and drove that for two-to-three
seasons. Then we bought a wrecked Mallock Clubman’s car and repaired and
campaigned that for a couple of seasons. Then from here we moved up to an ex-two
litre Dallara F3 car…a loaned 3.5litre Judd EV powered Lola F3000 car,
obviously modified from the F3000 car to accept the Ex Judd F1 engine. This was
a good car to get used to the sort of performance, slthough it didn’t handle as
well as the current GR55B.
What changes have you
noticed in the last 5 years?
Certainly
when David Gould brought out the DG37, which was based on a RALT F3 chassis,
initially with David Grace with a Cosworth DFR engine, the trend was set for a
much stiffer car. Prior to this the thought had been that a hillclimb car had
to be soft and compliant. If you’ve got a very stiff monocoque (chassis) that
allows you to run stiffer springs, the whole car is therefore a lot stiffer,
which exploits the potential of the tyres a lot more.
Watching the GR55B it seems
to be lifting a front wheel in slower corners. Is that correct?
Yes
that’s possible because it effectively runs quite soft in roll in back, but
very stiff in front so that’s how it loads up the front enough so it makes it
very sharp for good turn-in. Maybe in a slow corner it will pickup a front
wheel, with maybe two-to-three inches of daylight under it at times. The droop
on the front is effectively zero, but of course this is not the case at the
rear.
How do the Judd and NME V8
engines compare?
“Certainly
(the Judd was) different to this 2.65, had a little bit more power, more power
lower down, but in terms of ultimate performance there’s more to be had from
these (the NME V8). Purely the fact that they are just that much more modern
and lighter. The engine itself has lighter internals, so it picks up speed a
lot quicker. The rate of change of rpm is phenomenal.
Yes
certainly that’s partly true, but what you’ve got to remember is that a lot of
what you are feeling is the loss of weight (of the whole car). The current car
is up to 100kg lighter than the earlier generation Gould chassis, helped by
lighter engines, monocoque and gearbox. But I think that a change in tyre
technology, then we’ve been able to use a lot stiffer chassis in general and as
a consequence we are seeing performance gains from that. The chassis is made
very much with weight in mind”.
Martin reported that NME
will be servicing his current engine on his return to the
“NME
will do a leak-down test bore scope it, may have the sump off to have a look at
the crank and what have you. They (the NME V8 engines) are designed for a life
of three seasons.
Is it a gentlemen’s sport?
It’s
still a very genuine sport for friendliness, people want to win in the right
way. Don’t get me wrong, everybody wants to win. People want to be seen to be
winning in the right way, so if your competitor is in trouble and you can help
them out, then you do. Its fiercely competitive on the track, but good socially
off the track.
What is your current budget
for a season?
You’ve
got to look at it in context; our series is seventeen meetings (per season). I
wouldn’t say that we’ve raised the bar at all, that was raised a good few years
ago. There’s a level of expense that if you want to be competitive and in
chance of a win then that’s what you have to go to. We do our best to be
economical with the tyres. This season we had four-to-five pairs of rear tyres
and three pairs of fronts. It would have been very easy to have a new set every
meeting, but then at one thousand pounds per set or more, its just not
possible. Realistically if you don’t count travel expenses then you are looking
at around $30,000 Australian for the season. Any damage and it could get a lot
more expensive. I’d say this would be the minimum if you wanted to be on the
money.
I’ve noticed that
I
don’t think it’s a matter of time, its more a question of when something new
comes out that’s quicker. So if there was nothing built that was quicker for ten
years, then I’m not going to lose money (on his current GR55B). Inevitably
someone will come up with a quicker car, so that’s when all of a sudden a car
will drop its value. So one or more
generations of the current car, then it is going to lose its value.
What is your preparation for
a run?
Make
an effort to leave the paddock with the optimum temperatures; we don’t want to
be too hot by the time we get down to the bottom of the hill. Running down the
hill I’ll have a good look at the track, looking for debris and spills.
Honestly, just get the car set up nicely in the pre-start area, a decent amount
of tyre warming (burnout) and get your head-right, really!
Head-right?
Start
process is different for everybody. I like to do things a certain way and I
don’t like to be sat on the start line waiting for the lights. I like to be
able to go pretty well straight away when I want. But everybody treats the
process a different way. Some see the tyre warming as a bit of a psyching up!
Do you use visualisation
techniques?
Probably
subconsciously you do, but I am not there thinking my way through the run. I
try hard to remember what went wrong the run before and where you can go a bit
faster.
What are you thinking of
during a run?
Certainly
not looking at the corner you are in, you’re at least 50 yards or a good deal
up the road and sort of subconsciously dealing with the bit you are in at the
moment as well as preparing the car for the next bit.
So you come out of a corner
a bit wide and untidy: do you abort the run and save wear and tear, or do you
try to make the time up?
The
temptation is to always try to make the time up. You rarely do and it happened
to me just now. I went over the dipper, the tail got away from me as the car
went light and I was on to it straight away but did not make the time up.
Can you recover mentally
from such an error?
I
think so. I think any error you make, even when you hit the wall, as long as
you know what happened (you can recover). The accidents that seem
psychologically difficult for people is when they genuinely don’t know what
happened.
How are you finding Mt
Panorama?
I
thought we got a good feel for it yesterday. It’s reasonably open, so you are
not faced with lots of blind corners. You can drive it pretty much as you see
it and that’s a big help.
The
trickiest corner, where you start to lose the most time is the first corner
(Forrest Elbow). I think that if you can get that absolutely hooked up and
right then you are going to have a good run.
Do you think there are
different approaches to Mt Panorama?
I
think there’s probably only one correct line. For the first corner; putting
yourself into a position where you can get onto the throttle early. I think it’s
O.K to compromise entry speed for exit speed. So it’s more important to be on
the throttle early, than to go into the corner quicker. Except with the left
handed approach into the dipper, just carry as much speed into there as
possible and try not to brake before you turn in! |
