S550 Underhood Temp ideas

[gqneon]

So I want to lower my underhood temps. What can I do without destroying my hood or killing airflow through my intercooler/radiator?

Does removing the hood mat lower the temps underhood at all? (And will it damage the paint or anything on either side since I'm assuming it's there to insulate the metal on the hood?)

I was thinking a grill delete might help but I don't like that a vandal would have full access to the intercooler / front area when it's parked. Plus wouldn't that only help when rolling?

What has worked for ya'll?

Grill delete would help but if you don't want to do that you could dremel out a few holes in the stock grill. Possibly a better radiator like Mishimoto may help. The hood mat won't damage the paint, it is a fire retardant.

The air that goes in needs to get out, thereby creating through flow of air. This is not an easy thing to do without cutting holes in the hood and even then it can be marginal unless you pick the right negative pressure zone. Cramming more air into the engine bay just increases the air pressure in there if it can't get out and can actually hurt rad throughflow. A bigger radiator may help the engine if it's overheating but it's the thermostat that determines when the rad comes into play so a cooler thermostat may help more.

Why do you want to lower the temp? And by how much? You could try shimming the hinges to raise the rear of the hood and increase throughflow, this has been known to work.

Or, removing the rubber weatherstrip at the rear of the hood that is attached to the cowl. I have no idea if it works. But it has been suggested on here before.

I swear my temps have been a bit lower since removing that, although I have no empirical evidence as I'm too lazy to actually do a before and after test. But I definitely noticed that I don't hit 200* CHT as often as before where it was always above.

That will help tremendously, especially if you have another heat exchanger blocking the flow of air through there. And yes it will most likely only help when moving, but do you happen to race around at parking lot speeds? Personally I care about my engine temps when I'm barreling down the straight at WOT and 130mph...not when I'm putting around in the parking lot.

For help there, you should be running one of those fan heat exchangers if they make them for your application. But this will only help with IAT temps, not necessarily CHT.

We all did that with our CtsV’s and it did help.

I had my weatherstrip removed for a short time while my aftermarket hood was being painted. I removed the rubber weatherstrip and washer nozzles to be ready for my new hood install. The OEM hood seemed to shake on the highway with it removed and temps were the same with or without it.

Need a vented hood or at least a raised cowl hood (which will flow air over your windshield when you're moving, if designed right). Vented hoods also help reduce lift on the front of the car on account of the air damming up in the engine bay... in which case it's forced out of the bottom of the car. Not a huge difference, I'm sure, but it does. You may opt to cut out the "fake-ish" hood vents these cars have and put real vents there. Or not worry about it because it's not really a problem after you start moving.

The trackspec replacement hood vents should help, alongside their upcoming GT4-styled center vent. I just installed these on my car this weekend but won't be out on the track until next spring to really test.

Wow, Those look great, Anyone use these ??

Remove the coping, battery cover, and rubber weather strip.
Track a Whippled 15 and this was worth 10-15 F.
Makes huge difference in stop go traffic.
Sitting idle, the hot air coming out the gap is crazy.

To remove coping, loosen nut on wiper arms only a turn or two, put wood under arm to support, tap hammer or wood mallet on top of nut forcing shaft down out of arm.

I wish there is actually a vent towards the back of the hood above the engine so the heat gets pulled out around the engine instead of in front of the engine.

Also curious about this. Looks great.

Not many yet. They just released. The photos are from my car.
