Motorplex Tonight

[tinto]

plenty of trial and error I reckon - you definitely got short changed on the two-runs thing!

[kryten2001]

Kryten,

Next time you go try using Manual mode and not Sport Mode. Do a normal take off and if it starts to spin to much shift straight into second. This should help your 60ft time but you just really need to try a few different options.

yeah mate.. It would be good to get a good number of runs in with different techniques.. Problem is the huge amount of time you have to wait between each run, it sucks...

I need to calm the nerves and be more analytical about what I'm doing... Certainly shifting at 5-6,000 rpm rather than waiting for redline would help too....

[chrisgti]

What are you running mate? Pirelli or regualar GTI?

Isaw's car is just normal gti..

Your trap speed is good shows the car is making pretty good power, but I wouldve expected a bit more with the claimed 200kw + atw?

What was your 60ft time? A half decent launch in a GTI should be round the 2.1 2.2 mark.. DSG should be easy I wouldve thought, Launching the manual is a total pain in the ass.

[bwen]

What RPM were you launching at? if you still had stock tyre pressures I wouldn't be launching anything past 2k rpm to be honest, the wheel spin will just slow you down. You trapped a pretty good 104, you definately can get into the 13.7-8 if you had a better launch

yeah that's the problem, really bad launches. 60ft time is 2.9sec on that 14.1 sec run.... Terrible.

2.9 woah mate that is pretty bad... at least you know you've got plenty room to improve.. I thought the k04's were supposed to be nice and linear. Your prob just pscyching yourself out, I cant say I know anything bout dsg but I'd just try driving off the line at idle or whatever and then working your way up from there.

George, you sir are a legend..

I just tried your tip out on a full launch with LC on and TC off, and as soon as the engine started spooling up an the huge wheelspin started, I just dropped it into second...

Just the tiniest bit of wheelspin and it was on its way under boost..... Far far better launch and it didn't bog down or spin one bit..

I guess I'm going back again next Wednesday!

Not mine...... More like nice and parabolic.

I stand corrected.... Times were:

ET - 14.197
Terminal Speed - 104.04mph
Reaction Time - 0.687
60' - 2.552
330' - 6.375
660' - 9.414
660' Speed - 132.40 kmh
1000' - 12.017

Ambient Temp - 15.7 degrees c
Track Temp - 21.9 degrees c
Humidity - 64%

After a few launches tonight using GeorgeS3's technique, I'd be quite upset not be able to shave at least 0.3 - 0.5 seconds off that time.

Next Wednesday night it shall be I guess...

Any tips on how much pressure to let out of the tyres for better grip?.. 20psi sound about right? (too soft?).. I was running it street pressure (34psi if I recall....).. And only take air out the fronts I'm assuming? (less drag on the non driving wheels?)

Yeah was gona ask if you were a bit retarded when you said 2.9.. I'd say 20 is too low, and you'll prob lose a bit of trap speed too. Put 40 plus in the rears.. I think I remember Bug Racer sayin to wind up the rebound on your fronts (help keep the wheels on the ground?) Id say 26 27 round that in the fronts..

and yes you should be upset.. Tarmac tested a stock pirelli 14.1 @ 163km/h

good luck

ta mate I'll give it a crack...

The shifting from 1st to second as soon as the wheels start to spin will make a big difference I'm sure... Now I'll be moving forward rather than spinning and bouncing up + down......

Stiffen the bump , soften the rebound . I think thats how it goes .

24psi in the fronts 40psi in the back

1/4 tank of fuel

and watch the tacho , I know on the street you can hear the engine but its important to keep an eye on the tacho when manual shifting .

As for the end . Its 400m then 400m(might be 600 cant remember , dont know if they include sandtrap or not) to brake . I think you may have left it a little late

yeah I dunno why they can't put a marker or a sign or something to let you know...... I just had it under full throttle until I knew I had to brake...

Almost went off the end on the second run.. Those brembos had to pull me up from about 200km/h pretty damn quick.

[kryten2001]

hey check it out guys, wanna see the front quarter of my car? 5 pictures down....

http://www.motorplex.com.au/news/new...009_10_15.html

Yeah that piece of garbage I was racing caught a lot of attention.

Oh well at least I got the front quarter of my car on the motorplex website.. haha...

[POLARBEAR666]

Well I only managed to get 2 runs in coz some guy in a cortina station wagon blew the guts out of his engine.. Oil all over the track.. 2 hour stoppage....

Too bad for him, looked like it was ready to pull a high 19 for sure.

Anyway I screwed it up pretty bad (never been down the strip before) and had huge wheelspin on my first run, and bad bogging down on the second.

Ran 14.1 @ 168km/h (104.04mph).

Pretty crap quarter time, but the terminal speed wasn't too bad.

I gotta learn how to launch this thing. It's a real beyotch.

I got owned off the line by a stock standard Mazda 6.. It took me half the track to catch up with him - but when I caught him I blew past him going about 30-40km/h faster.

Sucks off the line. Or maybe it's me, I can't drive. Pretty depressing.. I also ate the worst hot dog I've ever had in my life. I'm sure I'll be suffering tomorrow.

Don't stress mate, most FWD and AWD go **** at the track because they put so much track prep down on it to make it sticky for the RWD. This means that instead of a clean launch you get heaps of axle tramp or if you load up enough revs heaps of wheelspin.

Very hard to be as fast as you are normally on the street.

My funniest plex time was a 14.9@105 in my old car....missed 3rd and drove rest of track in 6th lol.
