may not realise, that track day use is actually more strenuous on the
engine, transmission & brakes than almost any other form of motorsport.
The closest form of motorsport to track day use is actually endurance
racing. I will give you a few examples.
If you were
to sprint or hill climb the car, you would warm the engine in the paddock
to the correct engine & water temperatures, then the engine would
be driven under load for anything between 20 seconds to a maximum of 4
minutes. This may be carried out between 4 and 8 times a day and I am
sure if you do the sums, you will work out that this is not a lot of running.
Apart from the time involved running the engine, the major stress on a
sprint or hillclimb car, is the heat cycles it goes through.
a car, at most club level motorsport, it would consist of between 5 and
20 laps of practice and maybe a 10 - 20 lap race. Most of which would
be less than 20 minutes of running. Obviously, more stressful than sprinting
or hill climbing from its sustained use, but less stressful from the heat
Then we come to track day use. We have many customers who inform us they
use their car for road use and probably a track day once a month. Typical
usage during a track day; you turn up in the morning, do noise check,
then out onto the circuit, drive the car around until you fancy having
a cup of coffee. It could be 20 - 50 laps with no let up. You have your
cup of coffee, maybe even let your friend go out and do another 20 laps,
he brings the car in just long enough for you to change over, then hammer
around the track until lunch time. After lunch a repeat of the morning.
The track day is comparable with 100+ mile races, maybe even getting closer
to a whole club level season in one day. This is often with a car that
has not had sufficient modifications to cope with this kind of treatment.
An endurance car would have bigger brakes, larger cooling ducts, special
tyres, oil coolers and many other up-rated components to cope with the
rigors of this kind of use.
So when you intend on using your car for track days, try to remember how
much stress a track day puts through a car. Try to make your car as ready
as possible, giving it full overhaul before and after the event. Pay particular
attention to the parts, bearing in mind that they have the equivalent
use in one track day as one years road use, therefore may need replacing
after each track day. You must expect your car to require more maintenance
than a car used for sprinting, hill climbing or even normal racing.
