Truck Fest 2013: Smokey Big Rigs Burnouts & Drag Racing Revealed
( http://www.TFLtruck.com ) When you think of a Big Rig Semi...you probably
don't immediately think of drag racing...or do you? This weekend at
Bandimere Speedway just outside of Denver, Colorado hundreds of Big Rig
Semi trucks lined up on the drag strip to see which one is the kind of the
mile high drag strip and which one is the fastest mile high pickup
dragster. Can a big rig run a sub 20 second quarter mile? You bet. Can a
big rig run a sub 15 mile....no problem. Can a Big Rig run a sub 10 second
time? You'll have to watch the video to find out. In another fun and
informative TFLtruck video we see what happens when the Big Rig Semi Trucks
line up behind the Christmas Tree.

Top Fuel Nitro Motorcycle Import vs Harley - Larry "Spiderman" Mcbride 5.83et @ 232mph
Dragbike Live was on location at the Manufacturers Cup Finals held November
12-14 2010 at South Georgia Motorsports Park in Georgia when Top Fuel Nitro
motorcycle legendary drag racer Larry "Spiderman" Mcbride against V-Twin
Top Fuel Harley rider Tommy Grimes aboard the Ray Price Top Fuel Nitro
entry met in the final round. Mcbride ran an incredible 5.830 elapsed time
at 232.75 miles per hour for the win! This was a historic final
round,marking the first time a V-Twin Top Fuel Nitro burner would face off
against an import Top Fuel Nitro Methane injected drag bike.

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
