that is much worse than mine.

I am going to put a little piece of hose in, that runs to the underside of the car, as someone has mentioned. I have not noticed anymore coolant lately, but I want to do it as a precaution.

welcome to the Autox Floggers Society W2Rx8, you finally started running hard enough ....

hmm well I did notice that there where some spots even before that autox though? should I maybe go to the 15psi cap and extend the hose? In the past 5 days since cleaning that all off I have checked daily and no new signs of coolant but the temps haven't been to high here yet. Guess there is no alarm to go see the stearlership than?

Had a guy stop me on the road today and he was telling me about how the dealer here replaced his motor in his 04 and how they messed stuff of and blamed it on him.

For those that autocross and are seeing coolant loss (hard street driving and hot climates as well) - I wonder if the MazSport Cooling Mod would be helpful (with or without a larger radiator).

The reason I say this is that when auto-x'ing, you are running the engine real hard without a lot of speed to create good airflow through the radiators, not to mention the too high stock fan activation settings IMHO - in this case Mazsport mod will not only activate the fans at lower temps, but may provide more consistent airflow at the lower speeds seen during auto-x.

This could help keep overall coolant temps lower, thus less coolant system pressure and subsequent overflow - may even get a little more power from the cooler engine temps.

FWIW, while I do not auto-x, it is mighty hot here in the summer and I have not experienced any coolant losses at all.

could have a point for auto -x but I'm positive the mod does nothing on the track at higher speeds . My temp goes up to 101 deg C whether the fans are on full or not .

only problem with that is in autox how would that come under the rules? one thing in the rules is if the book doesn't say you can do it than you can't

it would be an allowed Stock mod for Pro Solo only, you'd have to remove it for regular SCCA autox

20.8.B.2 Exception: Stock category cars are allowed additional and/or alternate
radiator cooling fans. This allowance must not serve any other purpose.

Agreed that it would be much less helpful at tracks (maybe only at slow portions of the track, something like under 40mph). If you have cooling issues there - you need a bigger radiator.

But normal combo city/hwy driving (especially with hot climates) it would help.

Shame about not being within rules of normal auto-x.

well doesn't seem to be anymore of the coolant overflow so far (knock on wood) got an autox coming up on june 30th see if on our small course if I can push it hard enought to do it again.
