What are you using as a base load? Even the value I had posted on my Jeep is probably way too low and should be closer to 5,000.

A rough guestimate for just the internal friction overhead would be 1000 for a 4 cyl, 1500 for a 6, and 2000 for an 8.

Some more guestimates
When the fan is on that adds 100-150w
Ignition/engine management 20-150w
Lights 200w
