Our engine compartment is pretty full, lots of stuff in there and not alot of air space. I never thought about it being significantly hotter than any other car, but I don't doubt it. I know there is a practice in the honda community of adding shims to the hood so that the corners of it back towards the windshield are raised of the fenders. They say it keeps it cooler. I don't know if anyone has tried this on an SVX. Plus, I think it looks stupid.
