I totally forgot I was arguing with an engineer...*Math bomb*
In general, I'd assume lab tests run a far more efficient cooling system. Think about it, changes in air temperature not only affect the airs ability to disapate heat, but the change in air density also matters. Air density also comes into play when you deal with altitude etc. Even the little insignificant things, like bugs and rocks getting into the radiator fins can make a difference in cooling efficiency over 30,000 miles. A/C systems also make a huge difference. Not only does the engine get loaded by the compressor, but the A/C condenser gets first dibs on fresh air.One other thing I do wonder about, is the cooling system.
On a test stand in a lab, the engine can get supplied with however much coolant it needs to run at full power and stay at the correct operating temperature.
In a car, I don't know if the cooling system can transfer and dissipate all the heat the engine makes when it is running under a full power, full load condition.
That's where I'm from!! Good ol Pocono Mountain. You familiar with Brodheadsville at all? My step-mom's family are the Kinsley's and own the grocery store there. I was there a couple of weeks ago when I had just gotten my Caliber and learned quickly about which gear has best ratio/power lol. And learned how to heel/toe shift better because we're known of our curvy roads up there.The CVT automatically changes gear ratios as needed to get the best performance.
On a particular hill in the Pocono Mountains that I frequently drive, when going down that hill the engine is running at 1500RPM going up it's running at 3000RPM - in both cases, I'm traveling at 50MPH.
This demonstrates that our engines always need the correct transmission gear ratio to get the performance you need. They probably are a little too fussy in this regard.
Hi Cheekyboy21,Actually our cars is ready to change from Cvt to manual
I just bought the full backage of the gear. ( Ecu , stick , clucht , wires , gearbox ) t
I bought it from crashing caliber with 1.8L Engine and my engine is 2.0L
I tried it with out i change the Ecu,but the car won't go more than 2500 Rpm.
I havn't got any problem on swapping the manual transimssion.you just need to remove the Cvt and then u put the manual.
But there are more wire comes on Cvt transimission so i had to tight and keep it away,coz i dont want to cut it out.
