Heat management (and intercoolers)

[eflyguy]

Having already seen significantly different results from data gathered over relatively small temperature changes, I spent some time looking at the air induction system on the Stinger (GT) tonight. Two hours after a trip to Lowes, a nearby dinner, and a single "spirited" straight-line dash to the closest grocery store, I was almost overwhelmed by the heat when I popped open the hood. Ambient is around 70º F..

So I started a thread on making the fake hood vents functional, and even a small change in airflow can have massive benefits, but I'm wondering what else could be done to reduce overall intake air temperature. Thoughts are along the lines of spraying water over the intercooler, adding electric fans, or just increasing the size with a replacement unit.

Starting this thread just to see what others might have done, or researched, along these lines..

I put in Injen CAI’s a couple weeks ago. Before I had them I would always notice the ambient heat when getting out of the car after the 5 miles drive to and from the grocery, and all longer drives. I haven’t noticed since I put the intakes in. But haven’t done any substantial testing, just what I’ve noticed from experience.

My current thoughts:

Moving to an SRI has the airflow originally enclosed and enroute to the turbos swirling around under the hood some. That may help a bit. The VelossaTech snorkels may help get more air underhood, I suppose. The new intakes being designed by SSR, which are in front of the radiator, still have an enclosed route to the turbo, so I'd expect that wouldn't improve underhood temps.

But I don't think underhood temps are anywhere near as important as intake air temps. And if the intercooler is part of this conversation, it would be the charged air intake temp that's supremely important.

The issue with holes in the hood vents is the obvious rain/snow melt/moisture that will end up dripping into the top of your engine bay.

If you must know, I've been continually trying to mentally model a proper drainage system for if/when I drill out/modify the hood vents to actually vent. Designing a small tray and draining system to the side of the hood is the shortest route, and I've already got ideas on how it would work while still allowing air to escape. It's a similar idea to how many higher end gazebos vent at the top: the rain doesn't get in but the air can still get out. Liquids and gases travel differently, so it is literally possible to have the hoods vent while not having inclement weather enter the engine bay.

My current headache is that none of my mental designs have actually "cleared" the fire blanket properly, and of course I actually DO want that fire blanket there, lol

will an aftermarket intercooler help? anyone has feedback on the ultimate performance intercooler help? does it really improve performance

As i mentioned in a thread late last year heat appears to effect the performance of the Stinger. With most days in summer over 33c and regularly 37c (100f) down here the heat doesn't escape the hood well. Functional hood vents must help, id be first on board if kia approved functional ones. Last summer was crazy. Trees that used to flower in December started coming out in late October.
