Paul Walkers Nissan Skyline GT-R R34 - GRIP - Folge 235 - RTL2
Det Müller testet den originalen Nissan Skyline GT-R R34 von Paul Walker
aus Fast & Furious 4. Dies ist der einzige Rennwagen, der von den
ehemaligen acht übrig geblieben ist. Der Besitzer möchte 300.000 Euro
für den Boliden haben.

Nissan Skyline GT-R R33 V-Spec + Toyota Supra - Sound!
I have filmed a Nissan Skyline GT-R R33 V-Spec and a Toyota Supra near by
the Nürburgring. I really like the red color on the Skyline, but I'm not
sure about the carbon hood. Which one do you prefer: Skyline or Supra? Let
me know by leaving a comment behind!

Jessica Barton reaction to 1000hp Supra
Decided to take Jessica Barton for a ride in the Real Street Performance
1050whp Toyota Supra. We know she gets a little scared when she's not the
one driving. When she jumps in the driver seat we can see how the tables
turned! Fun day at TX2K13 in Houston, TX!
Black Intercoolers - Mythbusting Mighty Car Mods
Should you paint your Intercooler black? Does it help to
paint your Intercooler black?
Will painting your Intercooler black increase your cars
performance? No, it will not. The guys at MightyCarMods have made a
fantastic (no sarcasm, it's a great video) video explaining why you should
paint your Intercooler black.
The information they provide is great, but the conclusion is wrong. Let's
take a look at why.

Cold Air Intakes - https://www.youtube.com/watch?v=Hiod1c2Py70
How could heat rejection by convection be improved by adding an insulating
layer? The real answer? It can't. For those of you who haven't checked out
the video, it's fascinating and I highly recommend it. It's actually a
great video, and a well performed test, but it ends with the wrong
Lets talk about radiation and convection for a moment, and why one might
think they should paint their radiator black. It all comes down to
emissivity. Emissivity (on a scale of 0-1) is the rate of radiation that
can be emitted from a surface. In simple terms, how much heat it gives off
Aluminum Foil: E: 0.07,
Black Paint: E: 0.98
The higher the number, the higher the rate of radiation. Blackbody, which
has the highest rate of radiation, has an emissivity of 1.
Black bodies give off the greatest amount of radiation. So one might think
that making an Intercooler
black would improve it's performance, because it would give off more heat.
But this is not the case, because Intercoolers are not designed to
dispose of heat via radiation, but via convection.
Radiation: Does not rely on movement of molecules.
Convection: Does rely on the movement of molecules passing by the hot/cool
object which is giving off heat.
Electronical Stig is correct in his statement that emissivity does not have
to do with convection, but Intercoolers are designed to work off
of convection, not radiation! Why? For starters, because your car moves.
That's also why your radiator has a fan, for when it's stopped it can
supply airflow through it.
If the outlet with no paint has a dT of 100, and the outlet of the black Intercooler has a dT of 97, the
Intercooler with no paint is
rejecting more heat. This means the air inlet temperature of the engine
will be less for a non-painted Intercooler!
In the MightCarMods experiment, the fan was very far away from the Intercooler, meaning airflow was
actually quite low. I would imagine as the fan gets closer, the difference
in temperature between the black and sliver Intercoolers would widen further. Intercoolers are designed for
convection, not radiation. If your car is moving, your Intercooler is going to provide you
better performance with minimal insulation. Aluminum is commonly used
because it rejects heat very quickly under convection A simple example,
touching aluminum foil immediately after pulling it out of the oven. I
would NOT recommend touching aluminum foil painted black directly after
pulling it out of the oven. (Don't touch hot stuff, regardless).
There is not a single car manufacturer which comes with a black Intercooler stock (to my knowledge). Is
this because they don't understand emissivity or how to design an Intercooler? Is it because this a new
secret and now the industry will suddenly change? Absolutely not. Some of
the most brilliant minds are behind automotive engine design, and the
reason Intercoolers are not
painted black is because Intercoolers are meant to reject heat
via convection, not radiation.
- Insulation, hinders convection by adding an additional layer which heat
much travel through, prior to being rejected
- More restrictive, decreases airflow through the Intercooler, preventing proper
- If the Intercooler is
exposed to sunlight, which many are (especially with removed bumpers), the
black Intercooler will absorb
a lot of the heat, where as the aluminum Intercooler actually does a very good
job of reflecting the heat.
- Other hot objects (Exhaust manifold,
engine, turbo, etc.) will put more
radiation into the Intercooler if it is painted black,
heating up the intake charge.
- WARMER AIR INTAKE TEMPERATURE
How much you're going to decrease your performance by is highly dependent
on many factors. In many cases, it may be a small difference, and not worth
noting. The major point is, you will not see an advantage from painting
your Intercooler black,
unless your car never moves, and you don't use convection for cooling the
intake charge. Unfortunately, or fortunately, your car moves, and it cools
the intake charge using convection, so the conclusion.
Do not paint your Intercooler
