I've certainly slid on some antifreeze before but usually it's, motor, diff, or trans oil. Fortunately with antifreeze you sometimes see the steam/smoke first before things get really bad.

I'm sure glad the tracks I go to don't have any rules permitting the use of coolant cause at anytime it could be below 30 degrees 6 months out of the year.

 

I have the video if someone wants to host it.

 

Ever had to try and "defrost" a frozen cooling system? I have, not fun.... It's not like you just start the car and let it warm up....

Hmmm, I'm not seeing that worse than someone dumping motor or transmission oil on the track from car problems... Scary, but no one was hurt and no cars damaged.

 

To me, the bigger question (and risk) is wtf is the guy in the red 911 thinking??? He is off track left and decides to come back across the track to get turned around! By doing so he puts himself nearly directly in the path of the spinning WRX. Serious lack of track smarts...

 

That's a different car off the track left (if you pause it). I believe that is the black Porsche you see at the end passing him as he gets back on the track. It's definitely not the red one he almost hits.

 

I've been to 3 driving schools now and I've never heard of a no antifreeze rule. I've even looked through the club's rule book section on driving schools. This is seriously the first time I've heard of tracks or sanctionning bodies having this rule. It makes sence though, at the last event I was at someone dumped coolant on the track, no damage or off track excursions for anyone though.

 

Damn water pumpers

 

Dammnnn he came close to that red porshe, that was almost a lot worse

 

Nah, looks like there are 2 cars off on the left. 1 clearly is the black 911, the color of the 2nd is not visible but given that there are no other vehicles down there it seems reasonable to believe that it was the red 911. Highly unlikely that the red 911 was behind the subie going into the spin.

 

Yes there are two, but if one of them was a bright red Porsche, you'd be able to tell. It looks like 3 cars were off already in front of the Subbie before he got there.

As you said, it wouldn't make any sense for the red Porsche to cross the track to get back on so I would assume one of those two on the left wasn't him. It also seems the Subbie slides far enough that he would have passed the two on the left well before they could get back on the track.

 

I thought it was worth pointing out that the weather prediction for tommorow, October 24th, calls for low temps of 33 and 32 degrees F at Summit Point and VIR respectively.

 

Hmm, good point for those of us who have parked our cars for the winter.

Does anyone have a chart that demonstrates the freezing point of coolant/water mix as a function of mix-ratio/concentration? I have seen the little table that shows freezing points for a 50/50 mix (-35F), as well as 30/70 water/coolant(-67F), but I run 80/20 in the FC right now and was wondering if that is good to around 0F or not (we rarely see single digit temps down here in NC).

If not, then I'll be sure to partially drain the car before Thanksgiving and add more coolant.

Or anyone leaving their car sitting overnight at a track event. I just thought I'd mention it since I got a ration of crap for it earlier in the thread.

I'm probably only running 80/20 water/coolant, but that'll probably get you to zero or so. I admit, I've never found a chart proving it.... looks like 20% (50% to 70%) coolant buys you roughly -30 degress of leway (-35 to -67), SO 70/30 might be theoretically right at zero. I'm not that's exactly how it works though.

 

no water wetter? that kinda sucks
what about NPG?
