I usually drive long distances in my line of work, and one thing that usually annoys me during my drives is the accumulation of heat inside the cabin of my Jaguar 2.4, even if the A/C is one. I'm looking for ways to address this problem, and a friend suggested that I get a carpet dashboard cover for my ride. How will getting this cover help address the issue in my car?
A carpet dashboard cover will not directly dissipate the heat inside your cabin, but it will indirectly help to reduce it. The dashboard actually conducts the heat that reaches it through the windshield, and it will reflect the said heat throughout your vehicle cabin, heating other materials that conduct heat—such as leather, plastic, metal, etc. The addition of a dash cover, especially one that is carpeted, will reduce the heat that is reflected inside your ride. A carpeted cover will not conduct and reflect it, so you will feel less heat inside your vehicle. Aside from that, it will actually protect the cover from drying up and cracking under the sun, prolonging its life.
A friend is offering me a radar detector for my ride, but I'm having second thoughts about getting it. Isn't a radar detector illegal? My brother-in-law was fined because of using a similar device that enabled his vehicle to sort of 'hide' from the radar gun.
First off, the device that your brother-in-law installed in his ride was probably a radar jammer, not a radar detector. A radar jammer ‘jams' the radar gun of police officers so that the gun won't get the actual speed reading of the car. Meanwhile, radar detectors simply detect when there is radar used in its range so you will know to keep within the speed limit. With regards to the legality of radar detectors, they are actually legal in some states but illegal in others. To know whether they are legal or not, you must check the rules and regulations in your specific state. If the use of this device is illegal, remember not to install one lest you be fined or given some jail time.
What's all the rave about the new exhaust header tubes these days? A friend has been convincing me to switch the headers of my Jaguar 2.4 to some new headers that he was obsessed with, telling me they offer better performance because of their thinner walls. What's with the thinner walls, and how do they offer better benefits?
The performance benefits provided by exhaust headers with thinner walls can be attributed to two things—their lightweight property and their heat-dissipation ability. Compared to the clunky and heavy built of some exhaust manifolds, exhaust headers with thinner walls are lighter, so the engine has to work a little bit easier because of the reduced weight in the car. Aside from that, the thinner walls allow heat to dissipate faster. This leads to cooler, and therefore denser, air—which then leads to improved engine performance.
