Tracking a 964. Need insight.

Hello

Big misstake; It is vice versa. To hot more pressure, to cool less pressure.

Roland, you must be referring to tire pressures, right? Thanks for the tip. I have an infrared pyrometer with lazer sight. That should come in mighty handy for checking tire temps across the tread.

One more question. Engine undertray on or off. If off, should I also remove the side and rear shields?

This kid's getting way too much advice. I'm going to suffer the same fate that Superman did at autocross...

Bring chalk for the wheels, Tyson. We can both take a stab at getting our pressures sorted out. We can start at 33/31 and fine-tune it from there.

Hello

The most important thing on a race track are the tires. Now they will reflect how you handle them. They also reflect the condition off your car. You should find someone with the same tires and ask him for the "secrets".

keep your ears open as most will tell only 50% and leve the rest in the "air". Also each drivestyle will vary the numbers but perfect drives have mostly similar adjustments.

I´m a undertray believer and as long you like to stay on the track you can leave it on. If you think you will go uprod or offroad better preserve the pristine condition in your garage.

removing the side and rear shield will safe some more wight and will add more turbolence.

As far I see it Jack will be allways ahead off as he has the better car ( Hell I wantet to say the lighter car ). Stay behind him and he has to clean the track for you ( All those slow cars and the dirt on the track ) plus you have less drag and know the way. If you are a good driver you can speed up Jacks topspeed on long straights ( Chu Chu train is coming ) so he also has benefits.

This is why the american racers like the ovals as you can ply with the wind and strategy wind´s.

But first step is walking upright on the race track and train the body to control the car so your brain is free from balast and can think about geting in the fast lane.

Power is nothing without control.
Control starts in the head and not on the pedals or steering wheel.

Have some good shoes for racing and some good for walking. First encounters on the track is to walk around it and "read" the tamac. OK this isn´t usefull for beginners but if you are in the group with some proff they will show and explain more then you will ever see. Also if you walk have a brownbag for unusuall items on the track on hand. Every big piece of dirt, stones or screws, bolts, washers goes in there.
This gives luck to all.

Roland, thanks a bunch. Very useful and entertaining info. My tires aren't ideal for this situation, but I'll make do. I wish I still had the SO-2's on. Well I'm 1hr away from setting off for LA-LA land. Wish me a safe journey! I've got 1100 miles of driving ahead of me. That should give me plenty of feel for the car, don't you think?

Thanks to all for the info!

Wow, you're driving a 2200 round trip to go...driving.

I don't think I'd try that in any other car!

Hello

Just plan to have a set new tires installed for the trip back.

If you overheat your tires they will not be safe for a returntrip.

I'm jealous, Tyson. Not much I can add - I'm sure your in good hands with Jack. I would say only one thing about the brakes: if you can, find a way to continue your cool down lap once you exit the track, touching the brake pedal as little as possible, for another 10 minutes. This will allow air to flow over the roters and pads while they are still hot, extending their life. If you see my buddy Chuck Miller (metallic blue '73S) say hi! Have fun and give Jack a big hello from all of us.
