On The Run Trackday @ winton - 30th August 2008

new PB *1:40.7500s

It was another great day at winton. i finally had a chance to write the blog. kept putting it off since i got addicted to spore (blame shaun)

Session1 - im starting with 28psi cold. i had Qui as my passenger. i was stuck behind Deng / MREVOMR for the first 3 laps. it was quite frustrating as he would go 40kmh around the corner, and on the straight he would accelerate away from me as his car is a lot faster on the straight. at the 4th lap, he came off the track. i only got 2 laps after that and the semis is not even hot yet.
1:55.0900
1:51.8600
1:57.1300
1:42.2600
1:43.4600

Session2 - had Henry, as my passenger. he is interested in 350z and wanted to know how it handle around the track. this time i was doing 'left-right swerve' for the whole 1st lap to warm up the tire coz i notice today for some reason the semis took abit longer to heat up. it did help, but running 33psi still felt abit too high for me.
2:01.8800
1:42.1500
1:41.5000
1:42.4100
1:41.6900
1:42.5300

Session3 - this is the best session for me as this is the only session with no passenger and the track is getting warmer. im running 30psi hot and it starting to feel alot better. i had abit of traffic for few laps, but i managed to get 3 clear lap and did 2 laps of 1:40.7s and 1 lap of 1:41.0s. i found that maybe its time for new semis lol coz i felt the back is quite loose in some part of the track... but then also maybe its probably bcoz i got abit more power now, so i have to be more gentle with the throttle.
1:47.1300
1:53.7000
1:40.7500
1:42.9700
1:41.0500
1:40.7900

My Opinion
anyway, i did 1:40.9 with stock + semis. and now with full exhaust and Plenum Spacer, i only managed to improve only slighty. its more to do with driver error

with the mods, the car pulls alot harder and definitely faster. esp on the top end. but i chickened out and back off earlier on most corner entry and i stayed on the brake abit longer compared to when i did it in stock form. it might take abit of getting used to and hopefully next time i am there i can get a bit faster with this new setup.

im thinking if i can get 1:40.00 flat or even 1:39.999 with this setup then the next time i can start looking into handling upgrade, like swaybar, camber arm, etc.

Conclusion
next time i will try to adjust the braking point. now that i have more power, i can feel that i dont have to hit the corner as hard to be able to reach the same top speed or lap time. so if i enter the corner as hard as when i did in stock, i should be able to go faster right?

NO. for me its not that simple. i didnt enter as hard, coz i didnt feel i can handle it. with the stock form, i think i entered the corner nearing my limit of controlling the car safely around the corner. now with extra power, i have much higher entry speed, if i didnt brake enough, im entering too quick which lead to understeer then oversteer if i didnt handle it correctly. if i brake too much, im too slow around the corner...

i need to find the fine point to slow down just enough but still enter the corner as fast as i did with the stock form.

till next time
