What's the deal with all of the heat discussions going on RH? Anybody who knows anything about internal combustion engines knows that even a NA engine on full song will glow a set of headers cherry red-hot. This is a shot of a BMW M engine on full song, no turbos, normally aspirated. Heat is a function of the amount of fuel burned. Surely though, this could not be possible on a 928, not ever, right? And with a supercharger system pumping even more air and fuel it just could not be possible to glow a non-turbo manifold or a set of non-turbo headers cherry red-hot, right? I guess this pictures is just fabricated, because this just can't be possible...only turbo manifolds glow red, right? Steel glows this color at somewhere around 1000 F to 1200 F.
