This one should be fun... I figure there will be less cars than usual out on the track that day if it's a Porsche only event....

Thanks for setting it up Fred.

Sounds like it will be a blast. It's gonna be hot hot hot.... in more ways than one! :-)

Man I wish I had your guys TT brakes!!!!

You could flush the brake fluid with high temp stuff like ATE. If you don't like the feel of your brakes you could swap pads for something with a bit more bite. I think Thill also has high octane fuel. You could time it so your tank is nearly empty when you get there and fill up on the high octane stuff. Bring a torque wrench and check your wheel bolts before every session. Basically the same stuff you did with your 300zx.

Thanks !! So, ATE is the brake fluid replacement of choice for high temp situations ? Sorry for my ignorance, but do you have an explicit description of the brake fluid (full name, or is ATE sufficient?) Just like Motul has a bunch of lines, I'd like to know what is recommended specifically for the 996TT's.

Similarly, the brake pads.... what are the recommended ones and trade-offs advantages.

Thanks,

Andy

P.S. Yes, T-hill does have 100 octane, at least the last time I was there (2001). The last thing I want to hear is detonation, so I look at the 100 octane as 'insurance'.

pig4bill

I just mentioned ATE as a generic example of high temp brake fluid. You know Motul, and I've never hear of problems in Porsches with it, so you may as well use something you're familiar with.

As for brake pad specifics, you'd probably find your answer in a search.

mooty

yes, ATE is enough description. if the shop don't know it, you should run from that shop asap.

motul 600 and AP racing fluids are both fine. i used all three types with no prob in 993, 996.

I do suggest runing half tank 100 octane unleaded and half 91.....that way minimizing power loss due to timing retard..

AndyW

Will timing retard because of higher octane levels in the gas ?

mooty

i think in general you want more advanced timing until you reach detonation pt. higher octane will be harder/slower to detonate. so hi octane fuel should allow more advanced timing, in theory anyway.

AndyW

I agree with your theory. My question was maybe a misinterpretation of the previous post. I was wondering if the 996TT had an octane detect->change timing algorithm somewhere.

It would be contrary to what I would think would be what you would WANT. Higher octane=more stable fuel=less likely detonation therefore, you can probably be more aggressive with the timing.

That was why I was asking.

:-)

mooty

ah, gotcha.

Hmm...

looks like my car may not make this event....

Also since the mixture is more stable and harder to detonate under these conditions, a high voltage ignition system, or at least one in proper working order, is important to ignite the mixture. Most of our cars are fine in this regard. Just make sure you have good plugs, and in the case of older cars a good coil and fresh cap and rotor....
