Last year when i used my car on track and it was it's old spec, after a couple of sessions the water and oil was getting too hot to stay out

It's not a fair comparison - as car runs different management, intercooler and rad which help keep it cooler i think - but it has a 13 row Setrab cooler and the oil temps don't go over 85 degrees all day on track

It does however climb to 100 degrees sat in traffic - which i don't understand why it does that, as it didn't before i fitted the cooler
