From personal experience: The PTuning kit held up to track use beautifully. I ran the kit with stock radiator and Koyo radiator, as well as the setrab oil cooler that's part of their turbo set up. With stock radiator temperatures were fine upto around 75* ambient temperature. At that point if I continued to push the car the coolant temps would start to get hotter than I wanted (215-219*). I upgraded to the Koyo radiator and the temperatures stayed below 215*. I also learned that by leaving the heat on while tracking you could expect around a 10* difference consistently. Meaning if they peaked previously at 215 then they wouldn't go any higher than 205 while heat on. If you're running the greddy turbo kit then you're more or less out of luck. We had a local running the greddy kit that had upgraded radiator and oil cooler and still couldn't keep temperatures in check. The main problem being the greddy turbo only uses oil for cooling. His oil temps would spike up to 300 quickly and end up shortening his track time each session.

Oil gets to about 100-110 but have now got a oil temp switch in the oil line that I have wired to run a van attached to the oil cooler, I'm happy as long as oil doesn't get over 115-120c. I have literally spent a fortune to get the cooling system right.

Vmount setups seem stupid....the one thing you don't want is air exiting from under the car as it causes lift and a vmount forces it out underneath.

I run a vented bonnet too. I have a build thread on the UK forum so you will see the work I have put in to it.

PTUNING Turbo Kit
PTUNING Front Mount
PTUNING Oil Cooler
Mrsideways 3" Dual Pass Radiator
14" SPAL Fan

I will very closely be monitoring both coolant and oil temps.

Regarding the video you posted, he's clearly taking it easy on his car on Summit Main letting off on the front straight and other areas.

As for as coolant vs distilled water, you can absolutely do that. My car is running mostly distilled water, maybe half gallon of Honda blue, and one bottle of water wetter. I have an oil cooler and Mr.Sideways dualpass radiator (link below) with a single 14inch fan. I don't track my car but I built it to be tracked, daily'd, and beat on. Closes I've done to tracking, which I do plan on changing, is running at the Dragon. Not once did my car come close to overheating while driving it. There is also a guy in town that does track with a P-tuning kit that also has no issues with overheating.

Weight of the cooling system I'm not sure about. If it were by build, I would worry with it and try to loose weight else where. On another note though, being a dedicated track car, you most likely won't have the heater core installed so you'll loose weight there from the core and hoses being gone plus less coolant.

What lap times were you running, and how fast do N/A s2k's usually run? If you're boosted and running 5 seconds slower than N/A cars, saying your car "did well on track" is a bit misleading, because you aren't really pushing it, and that's probably a large part of why you aren't overheating. If you're pushing it, there's simply more heat to get rid of and you haven't tested those limits.

You cannot really make a statement of, "You don't have to have a vmount. I good flowing dual pass with proper air flow will work fine." based on a street car (which is really what you have).
