AIRTEC Top Mount Intercooler Upgrade for Mini Cooper S R53

Bolt on BHP, by lowering the charge Air temperatures, a remapped car has increased power by ecu changes that raise boost pressure and other parameters, this increase in boost pressure raise intake temps and power loss soon follows, by fitting an up-rated intercooler you lower these intake temps, in turn increasing bhp and making your engine safer

AIRTEC Test results – Tim’s 233.3 bhp (Airtec cooled) Tuned Mini R53 @ Amd rolling road 10th May 2013 – Note, Results below were with bonnet closed on every run.

Fits all Supercharged powered Mini R53 cooper S

Standard Intercooler – Peak power 204.9 bhp & 161.1 Ib/ft
Run 1 -Temperature Into intercooler from charger 150 degree & Out of Intercooler into engine 123 degree
Run 2 -Temperature Into intercooler from charger 152 degree & Out of Intercooler into engine 130 degree
Run 3 -Temperature Into intercooler from charger 155 degree & Out of Intercooler into engine 135 degree
Conclusion – the standard intercooler on a tuned Mini just doesn’t work, most owners know this, here’s the proof for other owners that didn’t know.

Competitors Intercooler 50mm core (Note, this version didn’t have Air diverter scoop) – Peak power 216.0 bhp & 171.4 Ib/ft
Run 1 -Temperature Into intercooler from charger 124 degree & Out of Intercooler into engine 66 degree
Run 2 -Temperature Into intercooler from charger 131 degree & Out of Intercooler into engine 67 degree
Run 3 -Temperature Into intercooler from charger 140 degree & Out of Intercooler into engine 89 degree
Conclusion – This intercooler worked much better than standard, but we feel the 50mm tube and fin core still couldn’t handle highly tuned Mini’s intake temps.

Airtec Intercooler 60mm core – Peak power 233.3.0 bhp & 190.5 Ib/ft
Run 1 -Temperature Into intercooler from charger 130 degree & Out of Intercooler into engine 44 degree
Run 2 -Temperature Into intercooler from charger 137 degree & Out of Intercooler into engine 47 degree
Run 3 -Temperature Into intercooler from charger 149 degree & Out of Intercooler into engine 49 degree
Conclusion – The Airtec 60mm bar and plate core works really well and keeps temps below 50 degree’s
