For you people with high output engines: the higher the cylinder head
temperature, the greater the risk of detonation.  I'm not sure if qtc's have
knock sensors, but I've detonated a hole right through a Rabbit head and the
results are NOT pretty!  With all this radiator/cooling talk we've been
having, the problem isn't just blowing head gaskets or warping heads (as if
that weren't bad enough), but more catastrophic problems with high turbo
boost.

I thought you'd want to know,
