GPL - Kyalami - I wanna be faster!

by Jim » Mon, 02 Apr 2001 13:24:19

I read the "What is the deal with Monaco and going fast?" thread with great
interest, and was hoping some of you could help me out in a similar way, but
this time at Kyalami. I just ran a 12-lap race against the AI there, and I
managed to clock 1.22.xx on five of those laps, the other seven laps being
slower. I've only once managed a 1.21.xx and the Papy time of 1.20.86 seems
very distant....

In the hope of finding out where I can save some time, I snipped out the
replay of my best lap and merged it with the Papy benchmark using GPL
SpyGirl. I'm fine up until the very slow lefthander "Clubhouse Bend" but
then things go to pot through Clubhouse, the Esses and the Hairpin. I take
all of these bends in second gear.

Any magical go-faster advice would be very much appreciated! I'm trying both
the Ferrari and the Lotus with Alison Hine's setups, although I've played
with the gearing a bit as I think she's quicker than me :0)

Cheers
Jim

PS. Links to trackguides would be really helpful if you've got them - so far
I've only been able to find Achim Trensz's guide on Ali's site. Ta.

Kyalami's basic is to always try to exit the corners a gear higher then you
think you should ;-)

Try it, you'll be surprised.

Kyalami is a hard circuit to improve indeed - Papy's time is not that
far away from what the fast people drive, if you constantly drive 1:20
- 1:21 laps you have a good chance of winning races.
I did some 1:19 laps, I got the biggest gain in that fast lefthander
(sunset bend I believe?) drive completely on the right side, even 2
wheels on the grass at the right side, and you can take that corner
fast in 4th gear. Practice practice practice..
Use GPLRA to study where you lose the most time.

Sunset's a righthander on my track map.... do you mean the lefthander after
Barbeque? I've been driving that in third on 50% throttle, might try taking
it up to 4th early and widening the line a bit. Thanks.

  I have to tell you, the program Lap Of The Gods will make you all feel
humble.
It has several laps at Kyalami and the benefits of downforce and huge tires
is immense.
Where we have to slowdown and almost tippytoe through Clubhouse, they were
taking that lefty at much higher speeds.   It was cool to see how closely
the GPL version
matched the LotG track that was filmed 10 years or so later.

Stay left approaching T1 and turn in sharper to take a late apex.
(i.e. don't just follow the groove)  It let's you accelerate smartly
towards T2 instead of tip-toeing through.

The biggest improvement you will see will come from getting better exit
speed.  All the straights are long enough to get a good gain from exit
speed.  Drive the corner on the limit, but slower than you think you need to
go...get your turning done early in the corner (turn in later, yet sharper)
and get on the gas firm and let the car slide to the exit.  Try very hard to
apply the gas at or a little after the apex...don't wait, even if it is just
a little bit of gas, you will still be accelerating.  Once you get your exit
speed pushing to the limits, you will find you can gain some decent time
with late braking and trail braking...but make sure that when you work on
braking later that you don't***up your exit speed...Kyalami is a perfect
track to work on trail braking.  Especially in turn 1 and turn 2.  Send me

aggressive lap I drove at Kyalami that really highlights the trail braking
and getting on the gas hard...I feel is is one of my most intense laps I
have driven.

They changed slightly T2 in the mid 70's I'm almost sure, because of the
poor run-off safety in that corner.  They modified it to a wider radius.

They mentioned that he slowed to about 100 for clubhouse.  I'm thinking "Damn,
I take that in first, must be about 40".  Track was identical, they hardly
slowed at all for Barbeque and the sweep.

I thought the track looked much wider on LOTG than it does in GPL.
Actually, this was true of all the tracks that are in both.  Zandvoort in
particular, looked wider, and the corners looked less sharp on LOTG than
in GPL.  Although they were definitely recognizable.

Setup - haven't got a clue.  I used one of the hotshoe setups and can't
recall which one.

Ist corner (don't know name) - this corner is a gradually reducing
radius so you will need to be gradually bleeding off some speed the
further into the corner you go.  I recall checking my lines through here
and it seems that the wider line - before turn in - appears to give
better speed through the corner.  Exiting is just a case of getting as
much power down without spinning the rear wheels or oversteering the
car.  You may need slight opposite lock here.

Barbeque - not sure about trail braking (never had that privilege), so I
would generally work on braking hard in a straight line and then turning
in.  A strong potential when doing this to spin during turn in or clip
the inside curb.  You will need to work plenty on guaging the best time
to turn and the amount of turn in.  To me this is the 2nd hardest corner
on this track.  I've spun here loads of times.  Exit is very much the
same as for the first corner, though it is slightly off camber I believe
and so it is easy to run too wide and onto the rough stuff if you're not
careful.

Jusket Sweep - get as wide as you can deal with (2 wheels on the grass
even) and then tap the brakes and throw that car towards the apex trying
not to clip the inside.  Get the power down as early as possible, but
remember, too much power will have you sliding off to the right onto the
grass.  If this happens then ease off the gas and straighten the car
out.  As long as you get the front and back right-side wheels both on
the grass together then you should get away with it.  Obviously it's
better to avoid this if at all possible though.

Sunset - I personally prefer to take a line a car width inside the
darker driving line when approaching this corner and then aim at the
inside of the corner whilst braking.  It's a long corner so, even after
the major braking has been done pre-corner, it is not necessary to do
all of it and you can bleed off some speed as you are in the corner
itself.  Exiting, I am normally in 2nd, but sometimes prefer to snatch
an early 3rd in order to avoid wheelspin.  Also, I'm sure that this is
one corner where getting the power down has to be done at the right
moment.  You have to learn when the car feels more like it's going to
keep a good inside line when you apply the power, otherwise I've found
myself having to back off for fear of drifting too wide.  Hard to
explain this but I'll give it a shot.  When going through longer corners
the car is very rarely just set solid.  If you look at the nose you can
generally see some oscillation from left to right and back again as the
front springs compress and uncompress back and forth.  What I discovered
was that, at Sunset for instance, if I waited for the left front to be
uncompressing whilst the right front was compressing - almost as if the
car was being rolled to the inside of the corner - and I then got the
power down at this precise moment, then the car was more likely to take
a line that steered/pulled towards the inside of the corner instead of
pushing away from the corner.  As a result I could get more power out of
the corner because I wasn't having to back off as much.  Has anyone else
noticed this?

Clubhouse - braking hard from 4th to first and take as wide a line when
approaching the corner as possible.  Find a braking point that allows
you to brake real hard, but not too late so that you overshoot.  You
really want to be attacking this corner as much as you can confidently
do so.  If you feel the back end starting to come around then let off
the brake just to balance the car again, at which point you should be
into the corner anyway and if done quickly enough you won't be carrying
much more speed than you would normally, so you can still get the nose
into the corner without too much problem.  It is not a major deal to
avoid the back end stepping out completely.  In fact this can help get
the car around the corner quicker than normal, though generally it's
just a case of getting as good a speed through here whilst hugging the
inside of the corner and not drifting wide.  Exiting, you really have to
wait, wait, wait - much longer that you would imagine - before you can
hit the gas.  Also slight opposite lock to avoid any oversteer.

Esses (if that's what they're called) - Hardest part for me to get
right.  The car really wants to turn in too much here.  As a result,
I've spun way too many times.  It's a real 'balancing' act.  I brake in
a straight line and then turn in once all braking's done.  I feel that I
should be going quicker here, but if I do that then I'm going too wide
for the second part so it's best to keep to the inside.  Although there
appears to be a small section of straight before the right-hand part
it's almost not worth trying to accelerate any as it'll only push the
car wide.  Get the nose into the corner early and then you should be
able to accelerate out early - and I mean full throttle - if you're not
carrying too much speed at the beginning of the corner and drifting
wide.

Leeukop - Attack, attack, attack.  Find a good braking point (you don't
want to overshoot) and then brake hard followed by throwing the car into
the corner (almost literally) and bleeding off some more speed.  If
you're speed's good then the only thing you'll have to worry about is
oversteer.  If things look like they're getting outta shape then a quick
turn of the front wheels towards the corner should settle them down
again.  Avoid drifting wide at all costs.  You'll lose too much time.
Power out in 2nd or 3rd - whichever you're most comfortable with - and
be aware of oversteer here aswell.  Also, the car should be right on the
outside of the track by the time you've hit the straight otherwise
you're either turning too much or not accelerating early or hard enough.

Ok then, what's my best here?  Just for info's sake of course and to
show that I have at sometime had a decent understanding of how to go
fast. :) 1:19.01.

Thanks to everyone for all your help, I'm now at 1:21.57 having put in over
80 laps since starting this thread... I managed 6 consecutive 1.21.xx laps
once, which was satisfying in a way but then I can't get lower than 1:21.57
so it's irritating too!

Think I need to get Leeukop sorted properly as the GPL SpyGirl combination
of my fastest lap with the Papy one shows that I was *ahead* whilst braking
for Leeukop but somehow very very slow out of it..... sob!

Cheers
Jim

PS. The World Superbikes have been racing at Kyalami this weekend just gone,
saw some of the racing on Eurosport and that track looks very different from
how it did in '67!
