actually a thing to note, if we got the last corner right our top speed down the straight increased from 140 to 150 :)

I took my Jazz Vti-S CVT & went to Wakefield on July 5 2005 with Circuit Club and managed to set a personal best time of 1m 20.916 seconds!
It was my first time driving and my car was all stock except the fact I did some weight reduction by removing the front passenger & rear seats and spare tyre. (Another thing I did was have a very light load of fuel, I had less than half tank at all times)
I met up with 2 other Jazz drivers, they being Andy and Pete, and met up with another 40 or so other drivers, cars ranging from hotted up Type R’s , HSV Maloo Ute, Skylines through to the Corollas of the late 80’s!
The day started off with open sessions whereby all cars were warming up and testing their gear, the track was still very damp and produced little grip until the track got dryer throughout the morning.
I started off cautiously as the track was still wet and that it was my first time driving on ‘any’ race track. I guess I pushed too hard on the 3rd lap when I understeer, then overcorrected and spun off onto the grass and caused lots of grass and dirt to enter my open window!
Anyway, I completed 5 sessions of about 20minutes, and 2 sessions whereby it was only for a ‘hot lap’ competition. In total, Id say I completed about 45 so laps, and most importantly, the stock brakes and fluid had no fade at all, and the front Dunlop Direzza 101’s 195/50/15 tyres had huge grip for its size and laps travelled, even when the tyres got really hot they still handled excellent. My lap times initially were 1m 25’s and lowered with each session, managing, in my opinion, an excellent time of 1m 20.926s on the 6th and final session.
I was using manual mode in the CVT at all time, mainly with the D in gear, however it was until the end of the day where I realised that using manual mode is S gear is the best!
The desire to gain more speed, to go quicker through each corner, the desire to catch the other Jazz’ers that were on the track meant that I had to practice different techniques to maximise lap times. As the Jazz does not carry a lot of speed into most corners at Wakefield, the tapping of brakes to weight the car for a slight oversteer and the power on the throttle to understeer, meant it was a fine balance of balancing the car just right for each corner and to get the right race line.
I'd exit the last corner at about 80km/hr and managed to hit 145-150km/hr at the end of the straight accelerating all the way right to the braking marker before the 2nd corner........braking hard just at the end of the 1st corner apex, settling the car to enter turn 2 and head up the sweeping right hand hill… it was fun and very go-kart-like to have a go especially in such a stock car.
The main incident for me was when I did lose control at about 100km/hr and ended up skidding backwards facing the oncoming cars. It is amazing IMO how if a car skids when going forward ABS kicks in but when I skidded backwards, the brakes locked and ABS didn’t kick in. Apart from this big skid, the running off in the wet, and the few times I ran off the track on the last corner, it was IMO relatively safe.
Anyway, for all those Jazz drivers, the next track day is coming so I will see you there!!
Ps. Pete is the one to beat, he is damn quick! Andy & I were chasing his times all day long but to no avail.
Man I just HAVE to make it next time....sounds so good!
nope, exhaust is stock.....oh the bottom of the air box isn't put on....or something like that...but no CAI fittedQuote:

oh and pete's cars manual :)
150kg?
Hehehe.. Yep, the rear seats weigh 30kg, spare tyre and tools 10kg, and front passenger seat is 20kg. I left my front seat in as I felt it may be upsetting the car balance too much, but in retrospect I probably wasn't driving hard enough for that to make a difference.Quote:

I guess you can look at weight reduction as 'cheating' but I just see it as a zero cost go-fast mod :rolleyes:
Also, Allan is right -- CVT auto "S" mode is fastest. I always used S mode down the main straight and manual gear changes around the rest of the track, but right at the end I used "S" auto for almost the whole lap and that got me a faster time - I need more track time to test this further!

I'm going next time for sure!!! :)
sorry haven't been on, been busy with other stuff . . .
just read through 3 pages and i can't remember it all, but i'll try.
The day was UNBELIEVABLE!!! It was PERFECT as andy said warm enough with the cool air.
I got down there early about 8.30 I think with my mate shane (rev-tech) and went through all the formalities of signing in. Parked in the open garages and met up with andy and allan.
Before I forget, for the people that asked, the mods to my car are suspension and I’ve cut the bottom of the airbox out hence it sounding a bit “meatier”.
First Shane and I went out for the practice session and the track was very foggy and wet from the night before. We took off down the straight and round the first corner we went easy enough . . . then the fog . . . and I think what I said to Shane at the time was something like “Shit!! Where’s the corner, which way do I go??:confused: ”. Fortunately he could remember as he had been there before and it was a hesitant reply “umm. . . left!:rolleyes: ” and left we went. Completed a couple of laps and started getting faster and faster on about the 5th lap coming around the top of the track about turn 4 I backed off the accelerator and suddenly we both became passengers of the car. Roll oversteered straight off the track. I hadn’t had my suspension settings setup properly as I didn’t know how the jazz would handle so we sought of had a better idea by now. We went off and adjusted it and it was pretty right for the rest of the day.
The rest of the day was awesome. As the track dried up and the day went on the times kept on getting faster. I managed to hassle a skyline for long enough in the first session long enough for him to let me through although prior to that on the main straight I must of looked like a grandma with a walking cane to him :p
Also kept up with an s15 and a couple of integras at different points in the day. But in all fairness if it were pro drivers in my car and those cars in front I think they would have had me for lunch. I also have video footage from session 2 onwards so most of it is on camera with a lot of funny/talking ourselves up/testosterone filled commentary from my co-driver and myself :p :o
I had a lot of problems with my tires more than anything during the day. The car held up absolutely amazingly during the day even though it’s a jazz:honda: ! After about 6 or 7 laps I think the tires heated up and were very slippery. I was watching the footage last night and the tires screeched around every corner more and more as the session went on:thumbdwn:
As for brake fade . . . It was nowhere near as noticeable as the tires as I was braking well past the markers right until the end of each session and even then the drums were managing to lock up the rears on several occasions:thumbsup:
With petrol I turned up with a full tank and did a full days racing. The light came on at the end, HOWEVER when I went to the mobil in Golbourn, I still had a little over 10 LITRES LEFT in the tank. I managed to do 199.7km in the day with 16.7L/100km. A bit above the usual 5.8L/100km:p
Would like to say THANKS and CONGRATS to both allan:thumbsup: :cool: and andy:thumbsup: :cool: for their unbelievably QUICK times in STOCK jazzes making me push myself harder and go faster and faster. And I think I did it for them as well.
Andy I agree with you . . . next time we should be passengers in each others cars to see differences of handling and techniques.
Can’t wait to get out there again. Next time I want to get a sub 1.20 time of some sort and I want to see a session out there that is just Jazzes :D :honda:
Pete :)
P.s. my little brother is down in Canberra atm and when he gets back I’ll get him to do the videos and I’ll host them up when I’m done. Photos will be up soon too.
