JOE-Z intake pipe got extremely hot at the racetrack
I don't know if it was from the vehicle sitting for a bit with the hood up, or if it is just because it is a metal pipe lying right on top of the cylinder head...it was so hot it almost burnt my hand touching it...I was also running the vehicle without the engine cover and the side covers as well, don't know if that affected anything.
Wondering if anyone else has noticed this, and also if an idea like heat-wrap would help keep the pipe cool and prevent it from heating up the cold(er) air from the stock airbox...any other ideas would be much appreciated.

I vote as well ceramic coating the intake pipe itself...
now question is this going into the OEM intake box
or a cone filter w/ some sort of shield (if this, consider wrapping the shield with DEI Gold Foil)
actually for overkill, on top of the ceramic coating, also run the DEI gold foil as well

GUYS…..
FYI: Everything metal in the engine bay is extremely HOT after Driving & Parking....
It will be HOTTER after racing too...
*** Please don't burn your hands by touching HOT parts inside the engine bay..
If you touch the intake pipe while driving the air inside the pipe is always cooler and never has time to heat up..
Since the air is NEVER stagnant...
^^ Please use caution, before attempting the above..
Thank You

Mostly with an OPEN ELEMENT INTAKE Design... which is already sucking in the HOTTER ENGINE BAY Air...
Opposed to the sealed ram air scoop bringing in outside air.
Moral of the story.. Don't touch Metal Parts in the Engine Bay after driving...

It actually was the Mercedes techs at the track who pointed out the temperature of my "cold" air intake pipe, when they were checking the car over after the morning session...I am not in the habit of touching metal parts in a hot engine compartment, but thanks for the comments.
I just wanted to know if anyone else has noticed their intake pipe being that hot, and what we could possibly do to reduce the heat and keep the cold air cold...especially in situations like track events.

I built a dc run a/c compressor and controller system that was wrapped around the entirety of the intake that did quite a good job of cooling the incoming air charge by up to 30 degrees of ambient outside temps.That means ZERO heat soak as well as cooling beyond outside air temps. It was difficult to install, not very easy to maintain and eventually I abandoned the commercialized version of the device because of the cost and level of dfficulty to actually make it work well.
Despite lobux claiming that I wasnt doing anything of benefit and that the temperature drop was being offset by the fact that the motor had to work that much harder to pull the amperage to operate the system, it apparently did work.
Granted, that in a constantly runningin environment ( ie cruising at speed, etc) this may be true, the system's intent and design worked perfectly to allow you to use your idling engine, while waiting for your turn on the track or what not, to keep your intake substantially colder than someone idling their engine without the system. I'm sure you could see the benefit of running the system to maintain a truly cold air intake, and then cutting the power right before your run so that maximum engine output was directed towards the wheels and not towards peripherals. This would allow you to briefly provide an incoming air charge that would be probably 50-80 degrees cooler than your competition, which is an obvious advantage. So does nitrous, but it gets expensive after awhile of constantly refilling your bottle....so it was shelved.
In fact, just the other day I thought of it fondly, as I set there watching my intake temps breach 150 degrees while waiting to run the 1/4 mile and in between runs.....
I have consider a different version of the device that would use a easily obtainable compressed gas(CO2) to affect the same outcome while being safer and cheaper than nitrous, but my time and money has been and will be directed elsewhere for now.

Other than some wrap, there really isn't anything that needs to done to cool the pipes exterior surface..
The Air inside is NEVER there long enough to heat up more than a few degrees compared to the ambient outside temps...
At WOT the air inside the ram air scoop, airbox & pipe is literally SUCKED up quicker than a blink of an eye..!!

I have to disagree, I watched my intake temps at the track the other night and it was 88 degrees outside and my data logging read 105 at its lowest point during the run.
It does drop dramatically from an idle, but still its hotter than just a few degrees off ambient
