I'd like to see some explanation as to how they think they're going to cool that thing. An Ultra with almost no fairing and wide open engine bay runs hot stock. These guys are going to boost the horsepower with performance upgrades, which only makes the twin run even hotter. And this is "Twintwin" is going to work inside a car engine bay? Did I miss something, like the giant propeller they used to cool the radial engines the site refers to?
