There was some discussion on this thread about heat soak that's worth reading...


Otherwise I have to say that I have ZERO data to back up what I'm sharing here. This is simply observations from someone who's been trying to pay attention to every bit of feedback the car's been giving me so far.



The heat from our engine bay fellas. What got me paying attention to it even before I bought it was the wife's car, the IS200t, which is obviously blown. She could run to the store and back, I could run to Atlanta and back (40 miles), and her car would be so much hotter that the V6 accord. Half hour later her car would still be quite warm whereas the honda would be cool to the touch.


So I was paying attention with the N. All but a few times I drove the car, and still to this day with about 1500 miles on it, when I park it, I pop the hood, feel the temps, and let it cool. I was lucky with time off from work and other stuff where I'm able to do this almost every drive, almost all the time in the garage.


My oil temp meter...using the break-in oil the meter would read 4-5 tiny hash marks past 200 at most, but would read that consistently. After my first oil change I noticed the meter being maybe right at 200, or one mark above. The car has, for the last couple days now, been running cooler, by the oil temp meter and by just the feel test when I pop the hood. It's taking less time to cool down.



You know what else I did while changing the oil? Took the engine cover off...:confused: I don't think the temps had anything to do with the oil! I think this cover holds in a lot of heat man! I don't think I'm trippin either!

I took my engine cover off about 3 weeks ago. And your right the engine does hold a lot of heat in with that cover on after you turn the car off. I would go for a spirited drive, and when I came home the engine bay would still be really warm hours after parking it. There's a lot of heat soak around the turbo of course and that is probably where all the heat is coming from. I just leave my cover off unless I'm at a car show or a cars and coffee. My oil hovers right at 200 and stays there. I'm on my 4th oil change and have 7000 miles on mine. I'm also using Mobil 0w30 in mine too. I figure since I change so often Mobil will work just fine. Some guys don't like Mobil, but for me its never been an issue since i change my oil a lot. I like things clean, in and out.

There is some insulation under it, as well as on top of the engine (injectors maybe?) Not sure if this is more for heat or noise.

Does it sound any different with the engine cover off? I always figured that thing was purely for looks

Sounds the exact same, but I did unplug my Sound Generator though also a few days ago. The car sounds so much better. Exhaust coming from the rear like it should, real engine noise. And now I hear what everybody else hears.

Most 4 cylinder turbo charged engines suffer from heat soak. It's not prevalent while in flight so to speak but more so when idling in traffic and when the engine is shut off.

There are remedies available that will help immensely and they are readily available;

https://www.thermotec.com/
https://www.heatshieldproducts.com/
https://www.demon-tweeks.com/se/motorsport/car-preparation/heat-shielding-protection/
https://www.zircotec.com/
https://designengineering.com/

These products will take care of most of the heat soak issues experienced by these engines. It's apparent in data logging, temps are reduced drastically. Another consideration is the installation of an intercooler. The OEM unit does an adequate job, but an aftermarket intercooler will reduce IAT's, as much as 50 degrees or more. It makes a big difference in performance and keeping heat soak at bay. Keep in mind, it won't get rid of it but these additions will help control it dramatically.

Can you tell me more about this Sound Generator? I've never run across anything about it online.
