Minimum speed through turn 1 at Phillip Island

[jimnielsen]

For those of you with data loggers - I though it would be instructive to capture some data about the minimum speed that you record after turn 1 and before slowing for southern loop. After Phillip Island this weekend - copy a snapshot of the relevant data and display it here!  Frank and Ray - I know you both have loggers...

I will start the ball rolling with a capture that shows the minimum speed at turn one for a run from my old giulietta (in 2005) and the 155 Q4 ( at Alfa Island 2010 ).

No guesstimates from looking at your speedo....

[Evan Bottcher]

Here's one for me.  Peak at 162kmh on the straight (!), drop to 139kmh.  Clearly in fifth gear the Sud can't accelerate towards turn two, I should do some comparisons in fourth gear.

I should also try driving it quicker - I really am only just breathing on the brakes for confidence before turning in, perhaps I should just glance at them instead...

Evan , I'm the same , nice to get some weight over the front wheels  before you turn in. However this weekend i was thinking of upgrading to a set of
" XL titanium testicles" for turn 1.

Great Evan.. if you look at the speed gap between fastest to slowest - you win so far!!

23 kph for your sud
25 kph for my ex giulietta
76 kph for the 155 Q4 - (need to purchase some of the Titanium XL's)

[Evan Bottcher]

What kind of lateral acceleration were you pulling through there in the Jooly on slicks Jim?  From my data my max is 0.92 but only briefly, mostly around 0.85.  That's on Toyo Rs.

(btw I think 0.85 G is probably pretty lame, and I should be looking for aforementioned XLs - I already have some titanium reinforcement)

[Anthony Miller]

Are those "Titanium Testicles- size XL" available from the same distributer of "HTFU" ?

[jimnielsen]

Evan - in the Giulietta - 1.25g on turn one, but 1.45g on Siberia, southern loop etc. (but this was with the Pirelli slicks). The Q4 is 1.1g at turn one, 1.25 at Siberia, southern loop etc.

I managed to borrow a datalogger for one session in March.  For the record I was running on Robin's 4 year old slicks, which I promptly wore down to the canvas (Thanks Robin!)

Peak of 185.7 km/h (but did manage 190.5 on another lap), and a minimum of 158.6, and it looks like I probably had a slide shortly after that as it dips down again.  Peak lateral G of 1.1 through Turn One.

Jeez it feels a LOT faster than 158km/h through there though....

This is all getting me pretty excited for Sunday.

Sorry, at this stage my data aq only works at home, doesn't work at race tracks. Very frustrating! 
Have re-positioned the unit for this weekend, tested, and all seems good to go. Fingers and toes crossed. Then I will know how fast in, and slowest speed, then I will post it.

[jimnielsen]

you'll need the actual data frank.. not just "jeez I must have been doing 250!!" Attached is some data from Ray P. His is 166.2 speed at turn one and 124.9 minimum.

[Ray Pignataro]

Jim in fairness it was probably raining, a head wind. foot on brakes and no nuts

[Sheldon McIntosh]

Sue seems to do alright with no nuts Ray.  What's her minimum speed, 166.1?

[Paul Gulliver]

Sheldon , I have just picked myself up off the floor . That would have to go very close to the "2010 AROCA QUOTE OF THE YEAR"

[hammer]

Jim,

Just as a matter of interest, were you running the 4.5 final drive or the 4.3 final drive in the Guilietta in that data? The maximum speed doesn't seem quite as quick as I would have expected. Nice a swift through turn one though!

BTW. Guili is getting a top end freshen up for Christmas as it has a leaky head gasket. Qld Alfa comp starts on Feb 20.

Cheers,

Brent

Hi guys,
I will be making my return to sprints this weekend at PI.  I am confident I can beat your minimum speeds quite comfortably.  Might even be able to get it under 120kph!!

Impressed?
Cheers,
Marco
