has anyone put an FI rx8 on track?

Sammytcl, would really like to see a list of your mods.

I'm curious about this. What mix were you running in your radiator before?
For racing, I think many would think to go just distilled water and 2 or 3 bottles of Red Line Water Wetter.
Olddragger- 70/30 blend and defi rad coolant(actually works better for me that the redline w.w.)

70/30 distiilled water/ coolant and one bottle of redline w/w. I just switched to the dei radiator coolant. I also put it in my a/w inter cooler---no more foam probs. It has a different inconsistency than redline/rp and the rest i have seen. i also have the mazmart water pump.

what lightweight battery--i tried one but it seemed the electric power steering was pulling it down.
With all that bracing i bet that dang thing vibrates when you hit the rough!
Lol.
My Innovate gave it up in 1 and 1/2 days--what power source did you use?

Yes, it would! Some cars even have that, stock
Of course there are some more practical ways of improving the cooling and not worrying about yet another fluid container to check..

Sure would, but then you have to figure out the extra weight you would be carrying around in the car with you, plus figure out the odds of it breaking and dumping water all around your tires, which would of course happen when you are in a high speed braking zone.

Any turbo rotary is going to be more difficult to keep cool on a road course. Do some research into what us RX7 guys do to manage heat and apply similar steps to the 8.

thats the moonshine waterless coolant...correct?
i have no idea why they call it moonshine. its not some alcoholic brew...
anyways, i understand its a waterless system. so is this more like a light oil type fluid, or some kind of super synthetic 100% ethylene glycol/propylene glycol mix?
what are the benefits other than (if its a propylene/ethylene glycol blend) that it can raise the boiling point. and being waterless, it won't contaminate or corrode metals and create a current draw with age...?
i'm pretty sure the cons with using this is that with higher boiling point, if you're not careful on temp monitoring, severe motor damage can occur if you overheat.
but what motor doesn't sustain damage when overheated?
thanks for ur input,
trochoid

I'm pretty sure the higher boiling point is a pro not a con. Sure you can get the coolant temps higher if you're not careful, and you don't want to be operating in those higher temps continuously, but at least the coolant is still liquid and taking heat away from the engine - giving you an extra "buffer" or time to back off.. Whereas once the coolant boils the heat transfer ability drops off sharply and you can say bye bye to your engine since all that extra heat has nowhere to go....

the temp you see on the gauge is simply the combined coolant temp, it's not representative to what the temperature is at some localized area, such as the hottest spot on the water jacket side of the rotor
by not boiling it stays in contact with this spot and helps carry the heat away, which will increase reliability and engine life
it may even exacerbate a coolant temp build-up issue in a sub-par heat exchanger system because of it's effectiveness, in the end it always comes down to how effective the radiator is, but the bottom line IMO is you're better off with it regardless in a comp/track car because again, the overall coolant temp is not indicative to what's actually happening at the water jacket surface

totally agree Team---if you are tracking etc its a good thing to have---we still even with the good water jacket design around the lead plugs, get the heat stress cracks in the housing around the lead plug hole. Since i do track and running a 70/30 ratio i have been thinking about this for the exact reasons you mention, but i havent decided yet.
Some people just think because this stuff doesnt boil etc then it is ok to run the engine at a hotter temp----wrong---dont do that. Speed Source backs totally off if their coolant temps get to 230F.
It is not just the radiator--although again i totally agree that it is the heart of the system, but it is also the placement and the amount of flow that can get through the radiator. That is somewhat of a problem for the 8. It is fixable.
Going to have to re-review your writeup on the Evans.
