Yes, I guess there's the inevitable compromise, too much heat in summer od not enough in winter. This reminds me of the noticeable difference in the induction systems in terms of heating of the manifolds. Milder-mannered road cars, at least when carburettors were the norm, have quite a lot of heating (via cooling system and even electric) to aid smooth running in all ambient and drivng conditions and aid emmission control eventually. Where performance was the watch-word, there was probably a lot less to keep the density of the air/ful mixture up. Interesting, I wonder since multi-point injection has become ubiquitous, if there is a difference here?

Doesn't say that in the manual
