I Track mostly down in south Texas at MSR Houston where we have seen track surface temps at 120F-130F at the hottest with 90F summer days. Even on a 55F day I hit 240F oil temp while short shifting to keep temps down.

From what I have read around the forum I would need two 34 row oil coolers just to keep my temps at 240F-260F on a hot day. It Seems to me that the AAM Oil to water cooler would be best in most applications with tracks in the south.

Is there a reason this hasn’t been used more?

P.S. I understand that automotive oil has a goldilocks area around 212F +/- 10F and it seems that air to oil heat exchangers cannot properly cool our oil to anywhere within that range.

TL: DR : Why not use Oil to Water coolers??
