I know some old race cars in Japan had exposed oil coolers...but they also had well curated tracks that were free of oil-line-popping debris like rock chips, and a spare engine at the ready. Most people driving on the street don’t have that stuff.
Now today it’s kind-of becoming a signature of a ‘Zero Fucks Given’ build. I kinda don’t get it? I mean, sure. You don’t have to give no fucks about being one rock chip away from a dangerous drop in oil pressure that will lead to spun bearings and a sized engine if not taken care of. But how is that good? And why is that a thing you want the world to know about?
