UKGPL Season 16 (2008-9) Novice '65 - Zandvoort (1967) - Jan 20

[Phil Thornton]

Does Zandvoort normally come with no pitwall, cos I can't remember...

Yes.

No

I've never seen one.  Expect Phil is talking about the pit stalls and TM is asking about the equivalent of the Kyalami Armco pit wall that separates the track from the pits.  Zandvoort doesn't have the latter.

Come to think of it, if you are far enough back in the pits you only get straw bales on the right as well.

I am talking about the armco a la Kyalami, since I'd rather not do an "Asbjeurn" and get DSQ'd when making a pit stop in the D1 race, or taking a Stop'n'Go in the Amateurs.

LOL a double negative here.  I was replying yes to your question "Zandvoort does NOT have a pit wall".  So just to clarify, there is no pit wall at Zanty.  Sorry for the confusion LOL.

Appreciate the clear-up Phil.

You're probably braking too late and deep into corners instead of focusing on early acceleration which is where the gain in laptime comes from.  

It is easier said than done though.  I think that I fall into the "too deep into the corner brigade".

How late and how hard I brake affects my rhythm. If I should start my braking earlier, that means I'd need to brake a little softer and over a longer stretch before I release the brake and start accelerating. Else I probably will step on the accelerator too early and need to adjust through the turn and get a bad exit, or I will need to wait too long before I step on the throttle and thus lose too much speed. Another option is that I brake too soft, and get a bad entry and need to recover before I can start getting out of the turn.

Either way, I need to learn two things at the same time, braking earlier, and braking a little softer, but not too soft. That can be a tough task for a driver closing in on 40.

[Asbjeurn Tverberg]

For 65s I tend to use 2/2 front bump/rebound and 2/3 or 3/3 rear bump/rebound with 114-131 N/mm front spring and 184-201 N/mm rear spring. Front ARB usually at 263 N/mm, rear at 280 N/mm. Cambers and pressures to get equal temperature accross the thread. The rest is down to personal preference.

As Jethro said brake less deep, trail brake to make the car turn on entry, accelerate earlier and harder, turning as little as possible.

Hm, my setup says 2/2 front and 1/3 rear on dampers. The springs are pretty soft, 88 N/cm front and 114 rear. The ARB's are set to 158 up front, and 105 at the rear. Everything is pretty soft compared to your "standar" settings. The tyres are perhaps a bit hard, though, 145 kPa both fore and aft. I'm not sure though, 'cause I haven't taken much notice of those numbers in the 65's, only remember that in the 67's I usually lay around 130 kPa. If the tyres are soft too, I'd might as well turn to Jethro's solution.

You're running way too soft imo. try a 2/3 for rear bump/rebound and at least equal arb front and rear. And generally stiffer, especially ARB at least above 200. As for tyres I run 145-159 kPa for 65s, depending on track. The optimal temperature seems to be around 100 degrees, so even with such high pressure most of the time you'd barely reach that.

..................... That can be a tough task for a driver closing in on 40.

Hah!  Bloody youngsters!

Youth is wasted on the young. 

[b_1_rd]

So...brake later and on throttle earlier then! Easy!

If only........!

[Clive Loynes]

Having practiced and practiced...and then practiced a bit more, I have managed to hustle my BT7 to a 1:28.8, which I am right chuffed about.   The car is a dream to drive and I've found a groove that lets me actually enjoy Zandvoort for the first time ever, lap after lap.



But now I find that I have to drive to Scotland tomorrow, on business, so won't be able to do the race.

Bugger it!

Pathetic excuse. Take yer wheel, hope the hotel has Wi-Fi and make the race!

[bernie]

Clive, forget your woes , while yoour up there go for a drive up the A38 . Gaurentee you will forget all about GPL for the duration 

[EvilClive]

Blimey, hope he goes in the right direction!! cos' that same A38 comes right through the centre of Bristol!!!!...could be a long drive ...
and anyway what a cop out..   

 "I can do 1:28's around Zandy and will wup yer asses"
 oops! forgot I can't make the race I HAVE TO GO AWAY ON BUSINESS!!??... how jolly (in)convenient

But wouldn't this make the tyres heat up even more? I tried letting some air out of the wheels, to 131 kPa, and also tried breaking a bit earlier and softer. It seemed like the tyretemps got under control all around. I considered setting the rear dampers to 2/3 instead of 1/3, but was afraid that the tail would be a bit too twitchy. But on afterthought, I don't think that it would be beyond controlable. I got a setup from Geoff, that I will try out tonight. We'll see how that will feel.

[Turkey Machine]

You worry too much about tyre temps Asjbeurn. Bolt on a DB setup without changing it, then work from there.

LOL

Just started snowing in Preston.  Maybe my trip will be cancelled.

Line is so incredibly important through the Hondenvlak-Tunnel Oost-Panoramabocht section! (Or what we in NGPLS used to call Himself Valley, after one of the members, who had a few manouvers when he spun and took out others, like race leaders and such...) If I get the line right, I can keep full throttle through the whole valley, if I don't, I need to lift on the throttle, or the car will lift going over the hills and far away.
