Heat soak is where you have been driving the car hard, generating a lot of heat in the engine bay. Then sitting still for extended periods of time. Letting that residual heat build up, actually making things hotter. At which causing your IC and other parts to become to hot to efficiently cool the air thus loosing HP.

I was thinking it may be something along those lines. So Turbosocks' functional hood vents would certainly help with heatsoak. I'm leaning towards getting those for the car.

I always thought heatsoak was only directed to a hot intercooler.

the whole point of an intercooler is to cool the air going into the engine. but since the intercooler is small, it can't keep up with cooling the air. and by having a bigger intercooler from either turbosocks or elecblue06, it will keep up with cooling the air. so instead of having a small intercooler which gets hot and stops cooling the air (heatsoak), the bigger intercooler doesn't soak up heat from the hot air going through it or the hot air around it and maintains cooling the air by having more surface to cool the air and being in front of the car rather than where the factory intercooler is located.

I doubt the hood vents will do anything to help the factory intercooler from heat soaking. it will cool down the engine bay a little. but ultimately to prevent heat soak, you will need turbosocks or elecblue06 fmic kit.

Heat soak actually applies ot pretty much any part of the engine bay that would normally perform better at a lower temperature. IE, the intake manifold, throttle body, intake tubing, compressor side of a turbo( though you pretty much can't stop this one) and especially fuel lines. A hot intake manifold and throttle body heat up the air that should have been cooled by the IC through convection, and thus rob some power. One thing you can do to help this (if you don't live in an overly cold area) is to remove the coolant lines that run through the throttle body, which obviously warm up the metal a rather large amount. The intake manifold would be much harder, as you would need to remove it, and shield the bottom with heat reflecting tape to help prevent radiated heat to the manifold itself. Fuel lines, if you want to go through the work, can be sleeved in insulating wraps, like the hightemp silicone coated fiberglass sleeves. Some people will say that all of these things will produce negligible gains, but if you do all of them, and help vent heat from under the hood, it is going to be more efficient, and help make more power. You can't of course fully prevent heat soak, but you can reduce it's effects on the components under the hood.

Heat soak is an over heating engine compartment in general (NAV or Turbo).
Heat soak is a much broader term than just air intake temperatures, it refers to the engine bay's heat situation in general.
How the engine itself absorbs and dissipates heat, how well the coolant system works, and of course how much power the engine makes during all this. All that heat has to go somewhere, mainly into the engine block and the cooling system causing temps to rise and heat absorption to drop. Oil breaks down and viscosity goes down, friction rises, metals fatigue, tolerances grow tighter. Everything in the general area is hot, so the intake air is also very hot, the air is thinner and holds less oxygen, the engine becomes prone to detonation, and the computer retards the timing resulting in a loss of power.
Now in a turbo car this also is affected by the IC being swamped with hotter air than it can handle, and therefore suffers from the last sentence above. The larger the IC, the less this effect is noticed.

The only real way to get over this heat soaking phenomenon is to fit proper air vent (or louvres) in the hood .. the BT/TS air vents are better than nothing, but fall short from a real cooling solution.

For that you'd need to run with the hood off :wink:

So apparently there are differing ideas on what heatsoak is. But in general it sounds like when parts under the hood get too hot to perform efficiently. The hood vents may not be the best answer, but they sound to me like an inexpensive way to help relieve the heat problem.

Heat soak is actually the transference of heat from one onject to another. The inter cooler gets heat soak from the engine bay the radiator for example. I the objects become hot for extended periods try are going ultimately bleed power.

I think one thing we can all agree on is that too much heat will reduce our.............. wait for it..........."Torque of the horse". :haha:

Been dying to use that. If you don't get the joke then check the article linked here: 2014 Hyundai Veloster Turbo - Car news - Zimbio
Lost in translation (gotta love it) :confusion:

"2014 Hyundai Veloster Turbo - Equal to the point of the 2014 Hyundai Veloster Turbo to get 1.6-liter engine that generates 221 hp and 211 pounds couple 2014 Hyundai Veloster Turbo Edition is the best choice between fuel consumption, speed and elegance. On this occasion Engineers 2014 Hyundai Veloster Turbo Turbo was better than the previous model 2013 has. Note that the first issue of 2013 is not about this turbo, why it is held in a second version. The third, in 2014, implemented triple turbo compressor displacement. Of course, there won `t be a triple turbo itself, but use pressure variation of gas separately and not simultaneously. This, in engineering terms means more acceleration."

"As a result, 2014 Hyundai Veloster Turbo is 014 change twice the power and torque of the horse. The 1.6 platform and will of six box they call EcoShift that interact with the driver, so you know, when accompanied change the speed of transfer. In this way, the engineers hope to improve the use of gasoline. Buyers can choose to buy the new 2014 Veloster with manual transmission. The weight is very important for sports cars. This model retains its weight, making it very light and aerodynamic. His rival, the Honda Civic SI has similar properties."

"Of course, the interior offers excellent comfort. The adjustable seat allows the driver to have a better handling car. Offered passengers feel comfortable with the space between the seats and the facilities of the “third” door. 2014 Hyundai Veloster Turbo features a media panel, which can be treated on the wheel. For a little more money, users can enjoy a 5-inch screen and high-quality speakers."

I have not noticed unusually high under-bonnet temperatures of my turbo so I doubt if heatsoak is a major issue (I had a car many years ago which had very, very high temperatures under the bonnet for some reason). I understand what the 2014 model is about and it uses the same pressure-wave variance turbocharging as we will see in Formula One next year. The Korean news release has been put through an internet translator which isn't the right way to do it. I have seen French and Russian translated the same way with similar results, because languages are contextual.
