Just picked up a 2011 Gen coupe 2.0t R-spec
Out of the box they're known to overheat on the track, the turbo is cooled via oil and water.

First thing's first, change engine oil, trans fluid, and coolant.
I'm trying to figure out what to buy since the turbo and engine both use the same fluids, i'd need something good enough to make them both happy.

The car gets tracked frequently, so I need to figure out what to do with it.

I was thinking Valvoline 10w-40 for engine oil, full syn. Pennzoil Synchromesh for trans fluid, and no clue for coolant.. any suggestions?
 
^^^Please disregard this poster, that's really bad advice. Use the coolant spec'd by Hyundai, otherwise the results could be quite costly.

You need to know the oil temps on track days in order to determine what is needed. Usually a nice synthetic in a grade one weight heavier is plenty.

I'd agree with you IF (BIG IF) the turbo wasn't cooled via coolant.
Water and very hot turbo isn't a good idea, even if water wetter adds that extra lubrication it'd need.

Right, one weight heavier is 10-40.
I do know that a lot of people run into heating issues, I'm investing in an oil cooler later on but for the time being i'm debating between Rotella syn and Valvoline syn.

Most tracks have outlawed anything but water and tiny amounts of of additives such as WW - any glycols are very slippery if spilled. Please reference the first three words of my original post.

For off-track use you could use whatever Hyundai recommends - last I recall it was 'conventional' silicated green coolant. Personally I would use G-05.

Water has the heat carrying capacity you need. WW is for cavitation protection and lubricating the water pump, not the turbo.
 
Changing oil is likely not going to help with overheating. Sounds like the cooling system is not sufficient. Consider adding another oil cooler or something.
 
Really? Every track i've been to 8+ and counting don't enforce that.
I know when I race in LeMons we're required to run water, but the reason being is LeMons breaks down too often to be cleaning up the track.
 
I don't think the 10w40 is necessary. If your HTHS is too high, the oil is thicker and probably not carrying heat away very quickly.

Do you have an OP gauge?

That's between you and the track, as they set the rules. I wouldn't want to be on the track when someone else had glycol in their cooling system.

Sounds like you're well on your way to moving more heat out of the engine with better heat exchangers.

Excuse me? I'm at HPDE's all over the country every year and I have NEVER been told anything about that "rule".

Source for your valuable info please?
 
Drag strips generally don't like ethylene glycol in the race cars, but I've never been to a road course where they even mention it. I run spring water and purple ice in my Camaro, and spring water and water wetter in my Corvette. I bought a bottle of purple ice about a month ago and it said not to run with distilled water. Curious as to why, I called Royal Purple's tech line, and the guy there said that distilled water causes problems in aluminum radiators and recommended bottled drinking water that has some minerals in it.

I recommend you try straight water and either purple ice or water wetter. These are additives that lower the surface tension of the water, making it more effective in transferring heat. Water itself has higher heat capacity and lower viscosity than ethylene glycol and will transfer more heat out of your engine. Just make sure you have at least a 15 psi radiator cap. This should suppress boiling up to ~250F.

Just as a sort of rhetorical question to your question...why do you think they invented water wetter in the first place? The specific use case is for plain water at the track.

Same. I've never been told this or even seen it written.
 
I believe there is a difference between a "Race Car" and a "Daily Driver" on the track.

For pure race cars yes water is key, and usually required.

But if you have your car you take to work everyday they are not going to enforce water only.

Sure, take your pick. National Auto Sport Association (HDPE's governing body) lists it in their own club codes & regulations, section 15.18:

I could go on, but you get the idea. Ignorance of standing regulations is no excuse for not following them.
