Turbo Heater: How Warm Does It Get?

Decided to copy the turbo heater found on the Facebook pages, here's a complete video of the build, install, and test to see how well it actually heats the cab. I found that at idle with the windows open and 28 degrees outside, the heater increased the cab temperature by 13 degrees. And with the windows closed, the cab temperature increased by 30 degrees sitting still at idle.
