For sure. iPhones are garbage regardless, but your cheapest bet will be to grab an old Android device off of Craigslist or eBay. You don't need data for Torque, and if you do, there's always WiFi. I set up my old Android to keep in my Jeep specifically for Torque Pro and streaming music to my head unit.

 

Bunch of iphone-haters! LOL
I actually like my iphone alot....................But my work phone is a Casio GZ'One, so I don't have any issue running android apps...............

 

I love my iPhone. Work provided me with a 4S. It's been very good to me. But I wouldn't purchase one on my own, far too restrictive.

 

Look at this. See any colder spots in the cooling system?

That's a pretty cool video!

 

I'm ready to believe that there is a big difference between the coolest and hottest places. Even our XJ radiators are dumping an enormous amount of heat. A large portion of the energy used by a piston driven engine goes to heat. I'll hold off posting the % of energy actually pushing the thing down the road, but it ain't high. (I'm sure we have improved from only using 10% of the potential energy in the fuel)

 

Thank a fellow member here, Dumajones, for the video. Seems to me the coolant temp appears pretty much the same, perhaps dispelling all the chatter about where to put temp switches..........

 

Dummy me. I thought it would be allot cooler after going through all those little tubes with massive airflow. It never occurred to me the temp stays about the same. Much thanks.

You know I love you Pete, but come on! you don't need to be educated in physics to know a radiator dumps heat!

(Yes CF, the coolant coming out of the cool side of the radiator is significantly cooler than what went in, if it was not, the whole works would be pointless)

 

Would be interesting to see that thermal video of the rad. Can definitely see the thermal difference in the 2 heater hoses. That's kinda why I re-routed our heater hoses away from the valve cover.....valve train runs hot enough, doesn't need any extra.

 

Agreed. I'll borrow that IR gun again sometime next month. I had time to (in Google advanced search), with "piston engine" and "efficiency" to find this.

>>Modern http://en.wikipedia.org/wiki/Gasoline engines have a maximum thermal efficiency of about 25% to 30% when used to power a car. In other words, even when the engine is operating at its point of maximum thermal efficiency, of the total heat energy released by the http://en.wikipedia.org/wiki/Gasoline consumed, about 70-75% is rejected as heat without being turned into useful work, i.e. turning the crankshaft.[1] Approximately half of this rejected heat is carried away by the exhaust gases, and half passes through the cylinder walls or cylinder head into the engine cooling system, and is passed to the atmosphere via the cooling system radiator.[2] Some of the work generated is also lost as friction, noise, air turbulence, and work used to turn engine equipment and appliances such as http://en.wikipedia.org/wiki/Circulation_pump and the electrical http://en.wikipedia.org/wiki/Alternator, leaving only about 25-30% of the energy released by the fuel consumed available to move the vehicle.

Dumajones will do that for ya.

 

Is that the V-6 ? Does that have the hot inlet on the left? Wait, I get it, those are heater hoses....

 

It's a 4.0. All physics conjecture aside, the coolant stays pretty close to the same as it travels through there at over 5 gallons per minute. That shoots all these hair-brained theories all to crap, eh what?

 

Well, in the name of science I wouldn't mind looking further. 5 gals a minute isn't exactly fast considering the amount or energy goen down. I guess they are suggesting a similar amount going through the coolant as propels the Jeep. There IS an HF here.....maybe I'll buy one of those gadgets for my own.

 

This isn't even that thread, is it?
