Underhood temps of 170-180F - normal??
Underhood temps of 170-180F - normal?? I have problem with PS fluid leaking somewhere nad was told it was because it boils. I have front-mount truck mani setup, for now everything is uncoated. I put IAT sensor to the PS reservoir, above driver side manifold, and after idling for some 10 minutes it was reading 175F (with 75F outside temperature). Is this normal, or should I do smth. immediately?
I would gladly do that... And I ordered turbo blanket more than 2 years ago from DrTurbo, and I still don't have neither blanket nor my money...
Actually I was surprised to see that there is no path for hot air to escape from under hood whatsoever :O that's crazy. In the back the hood (TransAm) is sealed to the plastic panel, no wonder underhood temps are almost the same as my water temps :o
I think I will a) remove rubber that seals the hood at the back b) wrap pipes and headers
We'll see how much that will help, for the start

I wouldn't remove that rubber seal, I agree that there needs to be a good path for air to escape especially while driving, but I had a friend who removed that seal and every time it rains he has a new problem, water pools under the hood on the intake and he keeps shorting things out.

Verdad Gallardo good point... if the water is stopped by this rubber and gets to the sides, then I think small 5mm rubber could be used to still direct water sideways but not seal to the hood

there is high presure air at the rear of the hood beofre the screen. you are best geting an extractor hood or fitting some vents to your hood and mount them nearer the front.
First thing would be to control the heat under there and then investigate way to remove any heat thats left over. Also might be worth looking at covering the cold side piping with some reflective tape or something. ight help reduce the amount of heat getting back into the intake air.....

hood has some 2" ~vertical plane at the back, I think cutting vents there would allow good escape path without worries about rain getting to the engine 
will take a look today

you are better to remove the heat closer to the front of the hood. also there is strong airflow over that section which should help 'pull' the hot air out of the engine bay.
Just my thoughts.
