How hot should the engine bay get?

The thread about the recent C5 fire got me thinking about how much hotter the engine bay in my 1LE seems to get compared to my truck and wife's car, and how much longer it retains heat. For example, the car has been parked for almost 2hours in 75F air after a 40 minute drive at normal highway/town conditions and I can't comfortably leave my hand on anything in the engine bay for more than a second or two. So, I was wondering if anyone has ever measured engine bay temps on theirs. I found the link below... not from a C5 but maybe somewhat relevant.

Hex hood vents and ceramic coat your headers if theyre stainless. two best things you can do to reduce engine bay temps

I had a 1979 jeep CJ-5 that was like that, you couldn't even pull the dipstick out because the handle was so hot. I put one of the aluminum billet oil caps on my 2010 and it got so hot I couldn't touch it either after the car got to temperature.
I wonder if my TL1 hood insert helps much.

Mine is the same way. I don't know specific temperatures, but I believe it was designed that way on purpose so the car doesn't need as much time to "warm up" if you choose to go out again only a short time after your previous drive. BMWs are designed this way as well.

Not exactly. Its inherent to the design of the car. Air forced through the rad, makes hotter air blow onto the engine/engine bay and then the pull-fans do it even more. Aluminum block and heads also lets more heat dissipate faster in the engine bay too. The problem is without hood vents or some sort of extractor, theirs a lot of excess heat. The excess heat soaks into your intake tract and that slows the car down as hotter air is less dense and therefore you'll make less power

Contrary to that though, engines run best when they are hot. The hotter the more efficient (up until a point obviously).

right. Hot(operating temp) engine, cold air, best combo

No heat-soak here. I have the TL1 hood insert and removed the drip tray. Heat pours out like a flood ..also when I get home after 90+ temps I pop the hood.

There are plenty of things to obsess over ... This is not one of them

I was thinking about this last night. Went for a drive got home and the car sat for 30-45 min. I then went to check my oil and I couldn't touch the dipstick (billet not stick) without a rag.

The heat was still radiating from the engine bay. Next time I will hit it with a temp fun

We work on just as many vettes as we do camaros(which is a lot!). Vettes have a much higher problem with heat due to the design. Less air flow through the engine bay, the opening is much more restrictive.

Just adding headers to a vette will sometimes cause heating issues. Luckily the camaro is not as a sensitive. Coating the headers as well as a fan adjustment helps out greatly.

As long as it doesn't get as hot as The Stig's you should be fine.

(Too soon?)

Silly question, but is this why people go to the 160 thermostat, or is that for soemthing else?
