Multi valve engines?

Asked by Aug 15, 2015 at 11:00 AM about the 2010 Subaru Outback 2.5i Limited

Question type: General

Do you think that an engine with FOUR VALVES per cylinder would normally outperform a
similarly sized or even larger displacement engine that had only TWO VALVES per
cylinder?    And what's the reason for this and is the one with multiple valves working
easier?

Bob, I knew it was more desirable, but, thanks for sharing this helpful link.---Mark

Bob, another person on this forum who is in the top ten category of car gurus, suggested to me that he would bet that a 2.5 litre Four cylinder engine would actually run cooler and more efficiently that a 2.5 litre Five due to its larger cylinders and better breathing. I thought I'd share this information with you since I know you like to stay informed. Also, see this picture I captured on the net about boxer engines. As you know, knowledge is power.
