So couldn't we say this, both intake makes power. The idea behind the JOEZ is logical and fair, which could outperform the LMS or Fujitsubo. But on the other hand, not by much, or even significant at most.
So in the end, you're not losing power with either, just one makes insignificantly more than the other. So unless you tell me you can feel the 2-5HP difference, it wouldn't really matter? I don't know, I'm just blabbing now, I don't even care that much, haha!

Actually the LMS does lose power, this has already been documented. There have never been reports of the Joe Z intake losing power, I'm simply bringing up a scenario which has not been brought up before that MAY have some effect on it's gains. But we're not comparing the Joe Z to the LMS anyway, we're comparing the Joe-Z to the stock intake.
I think everyone here is in agreement for the most part that the aluminum pipe will get hotter (be it a lot or a little) than the rubber pipe. The debate topic is weather or not the heat would negate the benifits. Some think yes, some think no which is why I'm going to check the temp of the Joe Z setup as soon as I park the car in my driveway after coming home from work. If the temp difference is small, meaning if I can comfortably touch the Joe Z as I was able to do with the stock one, then I'll be convinced enough to use the Joe Z intake over the stock setup.

Here is something else to ponder on with regards to air being heated while flowing through the SHORT intake pipe. Lets take a look at a coolant system. The idea here is that air doesn’t remove heat from aluminum but coolant (Fluid) does.
Now back to another example made earlier with the hair dryer. A hair dryer works like this: The airflow generated by the fan is directed down the barrel of the hairdryer, over AND through the heating element. As the air flows over and through the heated coil, heat rising from the coil warms the air by forced convection. The hot air streams out the end of the barrel. This is how you are going to get any measureable rises in air intake temperature. The key word in this is "FORCED CONVECTION"

If you really want to convince yourself, you better get a temp probe and stick it in near the throttle body opening and compare the stock intake temps vs the JOEZ and see what you get while driving around under various throttle loads.. A simple hand touch of the SHORT pipe won't tell you how much it's affecting the temperature of the RAPIDLY moving air in the pipe.

I understand that, I just want to see if there is a significant difference it temps... If it is a small difference, I am not going to worry about it, i'll know that it isn't enough to cause any power loss. I know it isn't going to tell me how much heat is being transferred to the intake charge but it will give a general idea as to how warm it gets while driving compared to stock.

Metal heats up quick, it also dissappates its heat quick, especially aluminum. So if there is indeed enough air flow around the engine bay when the car is in motion then it shouldn't be a problem. As far as sticking a temp gauge in there, it already has one... We just need a scanning tool to read it. I had a scan tool for my old Pontiac Grand Prix and did extensive testing with different intakes until I found one that gave me the coolest reading from the IAT (Intake air temperature) sensor.
ok... I'm off to work now before I'm late!

* This is the unit I currently use: http://www.rotorsportsracing.com/per...ng/powerfc.htm
In Monitor Mode, the Commander can display up to 10 parameters of data in real time. Monitor Mode can display:
Engine RPM, Ignition Timing, Vehicle Speed, Air Flow Voltage (Pressure Sensor Voltage), Injector Duty Cycle, Boost, Knocking Level, Battery Voltage, Intake Air Temp, Water Temp
Hope this helps clarify/reinforce where I'm acquiring my data for my contribution in this thread.

The air is litterally gone is less than a blink of an eye.. and thats at idle..
When your driving or engine revving the air speed inside the intake is Dramitcally increased.. It can literally suck your arm right off..
The air would probably have to hang around inside the intake for a few seconds in order to absorb heat.

Take the Stillen superchargers. They offer different stages. Stage 1 is usually just the supercharger. Stage 2 is usually the same set-up as Stage 1 but only adds an aluminum intercooler to cool the intake air before going into the intake manifold. Guess which one produces more power? As mentioned before, colder air is MUCH more important in FI applications but the principle is the same with NA engines.
Cooler air regardless of how it gets (intercooler) or stays (less heat soak) cooler will give you more power.
