here's my share:
Stock water pump:
2 hotlaps at 5+km track (Sepang, ambient air temp around 34C-36C) > max water temp 121C
Remedy water pump:
3 hotlaps at same track > max water temp 114C
5 hotlaps > max water temp 116C
A little bit disappointed, thought it can bring down my temp to below 110C. But good enough to last me 5 laps.
Other cooling mods I have: mazdaspeed bumper, 2 oil coolers, 2 row aluminium radiator. 90/10 distilled/coolant with 2 bottle water wetter, Braile 2317 battery at stock location but took out stock battery box to unblock the hot air from radiator, KS reflash (90C fan full on).
Maybe I have to V-mount the condensor to get more direct cold air to the radiator.

That's a hot day but you're running roasting temps for full throttle long straight application. You've done 250F on a race track. We recommend less then 200F at full throttle at the track. I hope you don't have engine (water seal) damage. Are you running a thermostat of any kind and what type of pulleys (Stock or under-drive)?

Quick question... what coolant/water ratio should I run for a car that may be stored in sub-freezing temps a few days, but only run in 40-50 degrees F? Track and autocross are going to be part of the car's duties?
I am installing the thermostat and pump in the next few days.

The RE-medy parts will not cure a severe cooling problem. They will strongly enhance the cooling and immediately usher the hot water to be exposed to air. The perfect combination is with proper fan control. When it's already reaching those zones I suspect something sinister is at work in the system.

I'm running with AP underdrive pulley.
200F for track day is equal to impossible here as the whether is really hot, the track temperature could be up to 48C but in my car I only see ambient temp 36C.
I have Aluminium radiator, sealed surrounding with foam, KS reflash (Fan full on at 90C).

on Stock thermostat. Was told that the stock thermostat open at 82C, so i guess it is not far compare to RE-medy thermostat.
Radiator is a 42mm 2 core radiator, can't remember the brand though. It's a replica radiator but definitely better than stock, observed that it brought down the temp by a lot compare to stock.
Next trackday I'll try with stock crank pulley instead, see how much it can helps.

I will try the Fujita Engineering (FEED)'s 3 Layer Big radiator soon. Lets see how it hold ups against all the other Radiators.

I am experiencing the same water temperatures reported above (up to 250°F) at the track and I do not want to damage my engine. Currently, I do not have any mods to the cooling system.
Have all the Re-medy stuff (in particular the water pump) been track tested?
And do you ship worldwide? I live in Switzerland
Thank you!!

i have been running the waterpump ever since it came out. works well. With Pauls help (remember this is a system consisting of many parts) i have been able to modify my cooling to where i never see over 200F on the track. I also keep my rpms down which probably helps a lot.

I always shift above 9k rpms on track. Just want to squeeze every bit of it from the renesis.

Well, did the install of the temp+water pump on friday. The thermostat was a pain to get at because of the air pump system, but pretty easy. Flushed the coolant system and of course I burnt the **** out of myself. 
Went with the 70-30 water to coolant ration with a bottle of water wetter.
Anyway...
Friday, cruising at 72mph, coolant was at 176-180. Oil temp 175. Ambient temp, 74.
Pre-pump-thermostat temps were around 200-205 for coolant, and 180 for the oil.
Autocross: Ambient temps were around 67. Cooler helps.
Run 1: Coolant: Pre-run: 180. Post run 205.
Oil: Pre-run: 170. Post run 200.
Run 4: Coolant: Pre-run: 190. Post Run 210. (Highest of the day)
Oil: Pre-run: 200. Post Run 210. (highest again)
Before the mazmart pump+Tstat I was posting coolant temps near 230, and oil close at 220ish.
So, this system over-haul worked very well.
In a side note, this was only my 4th autocross, and I managed to (finally!) win the rookie class! So, maybe the pump comes with performance gains and is lucky....
Overall, pleased with the product. Does what it said it would do.

That's the intended result. We actually did see some hp increase when we tested 2 plus years ago. I don't know that it means anything at all.
Are you running any form of fan control (AP, Racing Beat, Mazsport)?

Yeah, I'm sure its the full combination of everything:
My coolant needed changed anyway, so there is 2-3 degrees. Then I changed to a majority distilled water mix... add 2-3 more degrees. Add water wetter, add 1 more degree. Add the Water pump, 5-6 degrees, add the thermostat, another 4-5 degrees. Combine that with lower ambient temps... and we're at around the 15-17 degrees cooler I am seeing.
I'll see how this works before I add the fan control.
