Gotcha, and when you say start to move you mean off of midscale correct? Because it does move from cold to midscale after running a bit. When you pinned it did it still pull strong with nearly 11,000lbs. in tow?
Yea moving off the mid line. Power is not an issue at all. Truck pulls strong no problem. On ramps, grades etc. No problem. Just gets hot if you're on it for too long and making a bunch of boost.
Thank you so much for sharing that info.
Unfortinatly thermodynamics get in your way. In order to have an AC unit cool anything there has to be energy generated for heat removal. Air conditioners dont cool air, they remove heat, that requires a ton of energy, and the best AC unit on the planet doesnt hold a candle to a twin turbo V6. This is why you turn off your AC when you climb, which doesnt really matter with the Powerboost because the AC compressor is electronic. An additional AC compressor and evap would make the engine hotter.Thank you so much for sharing that info.
What we need is an Air conditioning expert to plumb in an additional AC compressor and evaporator coil for engine cooling. Switch operated for heavy load conditions. Power we have and it's cooling we need. The management systems won't care as long as the engine temp stays within operating limits. The more I think about it, the more I think it can work.
Water misting the rad increases its efficiency. It's neither 'fooling' nor voodoo -- it simply allows more heat to be removed from the coolant. The truck would be none the wiser that it's getting a bump in cooling capacity via water or a larger rad. The issue is heat transfer -- the ability for the cooling system to remove heat from the components it cools. There isn't a "yeah, but" to go along with it. The engine and trans temp are a function of the cooling system's ability to transfer it to the atmosphere -- and cooling down the coolant will cool down the components on its loop thus removing heat from the components.
Yeah, it's such a niche issue in very specific situations, often involving exceeding the 'large vehicle' speed limits. Some people want to maintain 70 mph up hill in the desert with 8 tons of mass (guilty). Amazing that simply going the speed from the dark evil govt mandated times of 55 mph, makes it all go away. People often forget the days of extreme motor vehicle tyranny when 55 was the federal mandated max speed. Now you can get pulled over for doing 80 due to obstructing trafficNo argument that sprayin water on the radiator and the Intercooler would extract considerably more heat from the cooling stack.
But I'm waiting for the manufacturer to equip the truck with the necessary apparatus.
