I have a 997S and drove Road Atlanta on a very hot day this past summer. Although the brakes remained very good, the pedal did get a bit soft. I have used ATE Blue in a previous 996 C2 and was happy with its track performance. In my GT3, stock fluid was fine.

Does anyone have any experience with ATE Blue in a 997S? Was the softness I saw typical for a very hot day in this car? Thanks!

 

If I recall, the stock fluid in water pumpers is the gold ate fluid. Same stuff as the blue. Already in your car. Anyone recall if I'm correct?

 

I don't know about all that but I've got my brakes apart and want to re-fill with ATE blue.. who's got the hookup for us Rennlisters?

 

Why not use Castrol SRF rather than blue? I use blue in the race car, but SRF in the 996. It is expensive but there is no comparison.

 

+1 for Castrol SRF if you will be on track in those hot, humid conditions.

 

I agree that the Castrol is great but the only issue is to bring along an extra can as I watched a guy ask everyone at WGI this summer for some and everyone there was running ATE Blue/Gold or stock DOT fluid.. On another note we swapped out the stock fluid (I just "lent" them a can of Blue actually) in a Caymen S at Summit Point this summer because (I was told) his fluid was cooking so I doubt Porsche is using ATE to start with... but honestly don't know what came in my 997S.

 

+2 for SRF

 

Motul 600: 98% as good as SRF for 50% of the cost.

 

Not really, check the wet boiling points between the two. You'll see.....

G.

 

Don't put water in your brake fluid reservoir, then.

Problem solved!

 

SRF huh? I'll see if I can find that around here. When I asked the local jobber shops even they gave me the looks of dazzled deer when I asked for ATE blue...

 

You can find it from some of the Rennlist sponsors online. I would think you could find it over on the peninsula though.

 

If when you refer to the gold ate fluid you are refering to the amber colored ATE TYP 200 then I have a question. As long as I have been doing this track DE stuff, almost 10 years now, I have rotated between the ATE Super Blue and the TYP 200 because every supplier said they were the same.

Then last week I was ordering some parts for the Volvo from Volvo supplier IPD and in their catalog they had the boiling point for the ATE TYP 200 at several hundred degrees lower than the Super Blue???? I asked the sales rep on the phone and he confirmed it. Then I saw in one of the Porsche supply catalogs the same old "both are the same, so rotate so you can see the change in color".

Anybody have a can of both the Super Blue and the TYP 200 to see what they have for boiling points? Need to try to remember to check the garage when I get home, but not sure it I have both.

Here is a link to the IPD website about the 2 ATE fluids:

ATE TYP 200 & Super Blue

 

Thanks for the feedback so far. One point to note. I talked to my dealer about the softening pedal and they suggested I go to ATE Super Blue. This dealership has been very supportive of track work to date so I am inclined to believe that the Blue is better/different than the stock fluid.

Anyone else in the hot climate had some pedal softening on the 997S?

 

How much experience do you have on the track?

Is it possible that you are misusing/abusing/overusing the brakes?

I don't mean this as a smart aleck comment/question, but if you are new to track events, it is possible that you are simply inducing the problem with your braking method.

If you are very experienced, maybe there is something wrong with your braking system. I have not heard about too many problems with 996/997 stock brakes that cannot be resolved with new pads/different fluid. For example, if your pads are too thin, you can overheat your brake fluid . . .

No joke about the SRF. That stuff is like miracle fluid. Pricey, but . . .
