ParticipantJust wondering, what’s the fastest and average lap times for the 80ccs in my-kart races?

I found that I tend to brake much later than Huffiz. This affects my cornering balance and revs thru the corner and onto a good exit. You will note that Huffiz has an excellent exit speed, which makes him formidable on a wider kart performance variance.I, on the other hand am a late braker. This is nothing to shout about, given for me it is easier to know when the kart and I am at the limits. I find it is very difficult for me to brake earlier as I have no reference whether I would be braking too early or at the right point for a good cornering speed. So I am a bit of a on or off type of driver. The problem with late braking is that it is so easy to get it wrong because I tend to be close to the limit… so you would often see me missing my apex when pushing hard. So when I miss apexes, I start going sideways and lose speed. I also will not be able to effectively keep my revs up. I am a bit of a Jacques Villeneuve style of driver. *he he*
[/quote]I have the same problem too, I tend to brake too late and sometimes too early (consistency problem here).
I noticed that because sometimes I find I lose out in exit speed to the karter in front if I don’t get my entry speed correct.
Even Luen said that I brake too late when he was following behind me once before.31 August 2006 at 8:16 am #3088sabelt
ParticipantLooks like you all fast karter likes to tail out before the entry. Would that save much time? For me i rather have smooth line and slight understeer on the exit. No wonder im slow. 🙁

not sure whether that is the fastest why round. tail out on entry is a very fine balance: too much tail, then you lose speed correcting & trying to find traction. but the right amount of tail, then you get the right angle to exit the turn.
smooth is usually better.

You dun need brakes at the last turn. :))
The idea is to maintain speed.
Just before the corner, lift off trottle 50% and slightly pitch the tail so you aim at the exit apex. once the kart is pointing into direction, slam it!
All this apply halfway thru the last corner.
Once u get this right, there’s no need to complain about your kart no power…[/quote]I mean the main straight (is there a back straight?), turn 1. Need big balls to brake late for turn 1.
For the last turn, I am slow there coz I don’t lift off and just drift through the whole corner :p Slow, but fun………..

i once messed up my turn 1 braking points and ended on the sharp kerbs on the exit which cut through the seat. yow!
damn… drifting round the parabolic is fun, but not when you start seeing the tyre barriers on the left heading in your direction at high speed! 🙂

Participantat the end of day, the moral of the story is to buy yourself a personal kart and practise. 🙁 $$$$$ 🙁
Just like Jules was saying, after 3000 laps, you will know what to do.

I just know what is latest braking point and turning point for sake of reference. Of course, I will not force myself to use the points.
At Sepang track, can anyone tell me to tackle turn 4 and 5? After the apex at Turn 4, will you stick to outside of turn 5 and make late turn at Turn 5? Or you go straight towards the apex of Turn 5, making a early turn? Besides Turn 4 and 5, is there anymore tricky corners? It seems that other corners are staright-forward. Anymore I should know? Can anyone help me?

Please correct me if I am wrong. In 80cc coporate kart, the fastest time is 1m 20s. For 100cc and 125cc, it should be 10 to 20 seconds faster.Note: Anyone who has posted to me , please wait for my reply in about 4-6 days. I am a social internet surfer who surf once or twice per week. Anyway, I will certainly reply to those concerned. Thank you for your patience.

Participanthmmmm… the fastest lap for 80cc 1.10″ clocked by one of the k3 karters.
Average for 60~70kg drivers about
80cc average 1.14″
100cc average 1.04″
125cc average 0.57″2 October 2006 at 1:14 am #3137Nohad

ParticipantI’d say the main thing to note is that no matter what kart you are driving – 80cc fun kart, 100cc piston port, Formula A, Rotax Max, 125cc shifter kart – the basics apply to all of them.
Smooth and minimal steering input, smooth getting on and off the brakes, smooth on and off the throttle. Unwind steering as soon as possible after apex, use all the track, get on the power early. These are far more important than getting caught up on how one should be driven differently from the other.
With more power you can throw a kart into slides a bit more mainly because if you get it slightly wrong the penalty isn’t as great as in a slow fun-kart. “Slides” as in barely noticeable oversteer to rotate the kart around a hairpin for example.
As for the curbs at Shah-Alam… there are a few that you can use without problems. Some I’d use only in qualifying or during a race if I really have to push, otherwise in a race it is too much of a risk to the chain to bounce over curbs and it wears down/overheats tyres – of course it depends if there is only a tiny advantage from using a curb or if it can really save you time.
At the Speedway Plus(elite) track more curbs are usable now after partial resurfacing than before, and some have always been usable, and very much worth using. There is still one that really should be avoided though (up-hill right hander that leads into the last section).
At sepang using the curbs is wicked.. the only curbs that don’t really work are the inside curb of the last corner, and maybe the inside curb of the left-hand T2 (or T3 depending on how you count the turns).

ParticipantGreat tips from a champion karter! Some of us are too caught up in doing big slides…..uncle jules also look super smooth when he drives, with fast times to show too.

Which curb at Shah Alam can I use? About Sepang racing lines, can you also answer?Note: Anyone who has posted to me , please wait for my reply in about 4-6 days.

ParticipantIt’s been a good 6 months since I’ve last driven at shah-alam so I might not remember everything correctly… but the last curb out of the chicane can be used, the first two can be run over but they are so big that it’s almost down to luck if you get a lucky bounce that’ll be faster than going around them – so not worth driving over really. Otherwise the slow left-hander going onto the back straight can be driven over – but not much gain to be made – it’s just one you don’t have to watch out for. The last corner can also be cut a tiny bit, but rather stay off it imo :).
I’ve already started on track guides similar to the speedway plus guide for both shah-alam and sepang but it’ll be a few weeks before I get fully into them and post them onto kartingmalaysia.com.
