2010 Sprint Thread  

260DET

Back before the track closed the exit of Caroussel used to be a WRX graveyard, something about getting a F/R torque shift mid corner, but I believe that sort of 'failure' for our aided car friends is long gone.

260DET

That makes sense but I'm not quite with Harry on the corner advantage, grip is grip wherever I would have thought. I suspect the non pro AWD drivers find it hard to know the limits, I've tried to set my RWD up so it basically understeers but so that can be mostly driven over, if you are keen and want to use the power.

HRD-GTR

grip is grip, that's not the question. AWD doesn't give you more cornering grip only traction out of corners. The higher speed/gear the corner, the less likely a 2WD car is to be traction limited, so less advantage to the AWDs. AWDs have a huge advantage wherever other cars are traction limited. eg in the wet, on dirt, on low speed say 2nd gear corners etc etc 4th and 5th gear corners don't really favour AWDs

Evo's should be quick around Lakeside, no doubt.

I've only driven one around there, an Evo 5, tired engine virtually stock standard, but on 18 inch semis.

Worst thing was the driver's seat was collapsing through right handers and I was falling out of it. I only got to do four laps because the engine shat itself (Had done over 200,000klm).

Anyway, never driven one before or since (and found it terribly one dimensional so I'm not aching to drive another), but I found the power down out of the Caroussel and Hungry to be the big advantage, traction while turning just wasn't an issue, contrary to my car. It was damned nervous through the kink though, probably a suspension issue.

I did a 59.1 in it. Given a proper seat and some time behind the wheel, 57's for certain.

HRD-GTR

yeah, exiting Caroussel is the main advantage for AWDs at Lakeside.
Hungry? I think its more about how much speed you can carry through it rather than power down out of it - its such a short chute into Eastern Loop it doesn really matter. At our sort of power levels a RWD with a decent diff shouldn't have any real traction issue there anyway.
Exiting E.Loop is also a little advantage to AWD, hard to get good power down there in a rwd, but again its only a slight advantage.
Everywhere else - kink, first 3/4 of Carousel, under the bridge, onto the front straight - is no advantage to have AWD IMO. Not at the sort of power levels we're talking about here.

Marlin

For sure, Caroussel is the BIG one, but as mine goes over the camber on Hungry and out of eastern Loop is just wants to slide. It's probably more a reflection of my car being setup for road rallies as opposed to a circuit.
But you are right Harry, 4WD is probably worth one full second out of the Caroussel, much, much less everywhere else.

superdave

Even I have trouble keeping traction out of Hungry

scooby36

i just plant my foot and let my single spinner do its thing. not for long though, 1.5way 4.3 coming soon :]

Evaded Motorsport

Yeah Corolla has no real issue with getting the power down.

Marlin

I wanna get one of the Berry/Newman cars out to Lakeside, either the 34 or 32 Stick the 35, they're too easy.

We will be there for the sprint mate, should be a top event and great opportunity to meet some of the locals.


Make sure you catch up with us, there will be a few 4's/imports there, I'll be in the EVO in my avatar.

Couple of us are camping...and most likely go out for dinner Friday/Saturday nights.

Mounfield Racing

Sounds good mate I know of a few from the Sunny Coast to Maryborough/Hervey Bay area that have also entered. add me to face book if you use it.

260DET

Yeh OK, I have not driven an AWD nor do I want to but would have thought that being able to split drive F/R would be an advantage most anywhere. For example, the really fast RWD cars (including yours) seem to end up getting a tail out attitude under the bridge which involves skill to control but also must lose time compared to if the car was straight. The more power you have with a RWD car the more that happens and the more skill is required to keep the car sort of straight due to rear end loss of grip.

I'm not the only RWD driver who has found that by turning the boost back you can do better times at Lakeside, the less power the more of a go you can have. I'd imagine that is not so much the case with a AWD where your all round grip thresholds should be higher overall. A driver aided AWD should be able to be set up with slight understeer at the limit so you just drive the crap out of it.

HRD-GTR

that's a point. constant AWD would tend to keep the rear in check on bumpy fast corners too. Even moreso if you add AYC. My Legnum with EVO style AWD & AYC was very very hard to unsettle.

Marlin

So effectively what y'all saying is this;
"If you have a 4WD car and you're not faster than the 2WD guys, you're a pussy."

Is that reasonable?

Evaded Motorsport

Yeah I think that is reasonable.

GOT04

6 Mercury Motorsport cars are out tomorrow at Queensland raceway to run a few laps.

3 are the new R35 gtrs, on full slicks.

im back out, it sure has been awhile, got the new engine and gear box in the car and a set of full slicks. its basicly a new car, have to wait and see where the development is needed all over again.

hope to see u boys there, come say hi if u see me!

clutch-monkey

what's the new engine like? less laggy than the previous setup?

GOT04

full boost at 4100rpm

revs are fast from about 2500rpm, dont really have lag anymore. on 19.5psi its got 524hp at the rear wheels.

not to bad. suspension and brakes are still very average.

HRD-GTR

jeezus - that's near as doesn't matter to double my horsepower!
524hp should be about 52.4sec at QR Sprint! hehe

lol

260DET

Yeh and I think cars on slicks should do 52.4 laps at QR Sprint too

superdave

Anyone know who to contact regarding the French day at Lakeside?

HRD-GTR

lol, you're welcome to bolt them on and be dismayed at how little extra performance there is next time we're at the track. I only got 5 tenths from bolting them on, and another 4 tenths from setup changes to suit the tyres. I was expecting 2 or even 3 seconds when I bought them! lol

next time I'll stop buying the cheapest tyres I can find (the reason for buying these slicks) and fork out for DZ03 or A050 which I believe are faster. medium compound slicks are for consistent performance over a race distance, if you want one lap speed you want one of the top line semis. hell I waste the best part of the first 2 laps just getting the tyres working, then you get a lap or two if you're lucky to get it right before you catch traffic.

scooby36

you can dooo it harry.
heres simon going 56 in his big power rb25 sil80

HRD-GTR

IIRC his official times were low 57s, but he prefers to time his runs by stopwatch off his video because he says everyone knows QR's timing system is inaccurate.


edit: found it: ns.com link about his time at QR

Marlin

LOL!

260DET

Yep, video+stopwatch is more accurate than a state of the art electronic timing system

Marlin

MATE, say whatever you want, but I know I've done a 63.5 around Lakeside. I know coz me mate timed me on his phone.

trackattack

Last Circuit Racing day at Lakeside I rented a Dorian, I assume they should be accurate.
They dont rent dorians for the sprints though, already looked into that !

Mounfield Racing

Agree Jeff Dorian timer is the way to go. But in reality, as long as every competitor at a sprint is timed by the same method, does it matter if your doing a 63.4 or a 65. If anyone is that good and that serious, go hire the track for a 1/2 day session, hire a dorian, pay for staff and an ambo to be on duty and go your hardest. If not, don't rag the equipment or method of operation QR have in place for your benefit.

Evaded Motorsport

Agreed, Dorian Timer's are the best way to go (there are other options as well) If you keep a look out you can usually find one for sale somewhere.

HRD-GTR

exactly! its the same for everyone.
not really sure why he felt the need to give himself half a second advantage over everyone else when his official 57.1 is seriously moving anyway!

Marlin

I'm assuming my sarcasm was missed?

Evaded Motorsport

It was noted.

Slav

Will come out next week to QR depending on what work is going on
