My guess is the test will look something like this:

I would say the initial results are encouraging, already +1'C in 5 minutes that's an increase of 3 degrees C in 5 minutes.

5 minutes later, 13'C. Or increase of 16'C in 10 minutes

5 minutes after that, it reached the desired 22'C (68'F).

-2'C to 22'C in 15 minutes. Oh and this is with out the engine running, since I have an electric coolant pump.

Final test will conclude with a 20 minute measurement, because I am can.
Reading was 27'C after 20 minutes.
That's fast enough, for now....
That test was 3500 watts with out the heater fan going.
This test was also on a fairly mild day that was right about freezing. This winter it could be starting out at 0'F and would take about 15 minutes just to get the engine to where it was freezing.
My guess is it will warm up about 60% faster, if I repeat the test as I did before, but I want to use that heat for other stuff besides just warming the engine up some.
The 5500 watt element is so big because I want to be able to defrost the wind shield, possibly start to warm the contents of the diesel fuel tank and maybe run a second cab heater.
