Unless all the various heat exchangers (radiator, engine oil cooler, ERS coolers etc etc) are exactly the same and split halfway and mirrored on each side then there will be a different transfer of heat from side to side making the air coming our of the back different temps. Therefore it would be useless to do this to compare temps with that idea.itix wrote:I actually think that he/she is right rather there being some weirdness going on. It actually looks a lot like one of their old ones from the pre season testing so quite possibly they are doing evaluation.GM7 wrote:This is surely to compare different temperatures, if the temperatures obtained from the left side are good they choose the smaller engine cover.
