First troubleshooting process question, what changed? The radiator? The radiator is smaller ("stock radiator, while thicker from front to back, by about 1.5 times") and the picture appears to show fans that move air across 60-70% of the radiator.
Harold,
Correct, the radiator changed. That said, we never ran it with the factory radiator as it was unable to hold coolant long enough to try it. I would say your estimate of fan to radiator is correct, however the factory setup did NOT have any fans other than the standard engine fan - which we still have, but it does nothing to push/pull air across the radiator as it is 3' below and 3' behind the radiator.
It's tough to get a feel for how this is setup from the photograph. The radiator is about 5' off the ground, sitting at about a 15 degree angle, such that air gets jammed across it from the roof air scoop. The engine sits backwards, when compared to a 'normal' engine orientation. The engine has the stock fan, but as noted it above, it does little else besides blowing air and presenting an in-your-face body part remover if you are not mindful of said body parts.
Take Care,
