Going only by what I can see online it seems that even the FI TT kits and AAM TT kits don’t include Upgraded radiators. This seems to hint that the stock radiator can handle addition horse power well enough for a street application.

If it is true that the stock rad can handle a turbo application, it doesn’t seem too hard to believe a N/A 370z rad could handle the additional load from cooling the oil.

Now a TT 370z with an oil to water exchanger might need a rad upgrade.

TL: DR : If a TT 370 doesn’t require a rad upgrade why cant the stock rad handle cooling the oil?

What radiators are known to leak? (so I can avoid)

I have run into this engine oil heat issue as well. It seems that even with the 34 row coolers we can’t keep our temps down.

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??
