Post by Keithr0Post by NoddyTrust me. I spent three years competing in Karts after I retired from
drag racing, and while it's the most fun you'll ever have with your
clothes on it will totally destroy the enjoyment you think you'll get
from *any* car :)
Yearh, tried it a few years ago at a "Team bonding" day at Eastern Creek
Raceway in Sydney. They were proper karts, but, obviously, hire units
not top racers. I was a bit shocked at first by how heavy the steering
was, but given how high geared it was that was, I suppose, to be
expected. Out on the track lots of fun, there was one left hand sweeper
where you could hang the back out, and play it with the throttle, well
until, inevitably, I overdid it and spun out.
They're certainly hard work, but incredibly enjoyable.
The Kart I owned was a thing called an "Arrow A9s". They were all the
rage back in the day which was very early 1990's. Don't know if they
still make them, but there's probably a number of them still in service
as they were enormously popular. They were powered by a 100cc Yammy 2
stroke engine made specifically for Kart racing, and they ran direct
drive single ratio gearing with no clutch.
To start the things you would basically run along beside it pushing the
Kart while holding the rear end clear of the ground until you had some
speed up, at which point you'd drop the rear onto the ground to "bump
start" the engine and then jump in the seat as soon as the engine fired
and hit the gas pedal. To shut it off you'd simply stand on the brake
pedal hard enough to bring the thing to a complete stop and stall the
engine.
Sounds pretty pre-historic, but it was easy enough to do and worked
well. Some of the little kids had their Dads do it while they were
sitting in the Kart ready to go. I haven't had anything to do with
Karts in an awfully long time and don't know if that's what they do
today, but it was the "state of the art" back then. Obviously races were
run on a rolling start.
As for performance they were quite impressive. Being direct drive with
only a single gear ratio you had to balance your gearing choice between
straight line speed and acceleration, but on some tracks you could get
moving. The engines were good for 14000rpm, and at a track like Geelong
or Kerang which had exceptionally long straights you could hit 160km/h
pretty easily which is fuck-awful fast with your arse cheeks an inch off
the asphalt.
Post by Keithr0I'd have gone back for more but it was a prick of a place to get to from
where I lived.
I was lucky in that where I lived in Altona there was a track in
Brooklyn which was about 7 minutes drive away. There were also a number
of decent tracks in Victoria back then, with the furthest away being
about an hour & a half away.
It was a period that I really enjoyed as it was *loads* of fun for not a
huge outlay with very little time & expense required between meetings.
The biggest expense was tyres which were under 200 a set back then with
a couple of sets easily lasting me a year or so, and gearsets which were
the most common consumable as they would wear reasonably quickly thanks
to them being made from laser cut aluminium and not being lubricated
while you were on the track as you weren't permitted to run a chain
oiler. Outside of that there was bugger all. 20 litres of fuel would
last you a long week-end.
It was certainly great fun. Hard work, but fun and I thoroughly
recommend anyone avail themselves of driving one if they get the chance.
It'll make your car seem positively hideous by comparison :)
