Mount Intercooler for Mini Cooper
key component to any supercharged engine is a high quality intercooler. As air
is compressed a by-product is increased air temperature. The intercooler’s
job is to reduce the temperature of the compressed hot air exiting the supercharger
and entering the engine. The MINI Cooper designers included an intercooler with
your Cooper S that is too small for enthusiasts seeking higher horsepower gains.
Alta Performance air-to-air intercooler is 100% larger than the factory unit.
Our intercooler still fits under the factory hood with no cutting or trimming
even though size is nearly doubled. Overall internal volume is increased by
with your intercooler is a new intercooler air diverter to direct air from the
hood scoop over the surface of the new intercooler. This all metal air diverter
seals to the underside of your hood and directs all of the air entering through
your hood scoop over the entire surface of your intercooler.
Included, as an option for your air diverter, is a water spray jet for extra
cooling in extremely hot conditions. When racing, endurance driving, or driving
on a hot day the water spray jet can douse your intercooler with a cooling spray
of water. As the water evaporates off your intercooler it will increase the
efficiency by over 200%.
“My times on the second day were over a full second faster, so its likely
the "shpritzer" was making a difference.”

water-to-air intercoolers may be an alternative to air-to-air don’t be
fooled by false promises of huge gains over our intercooler.
Expect 4-6 hours for mounting a water to air intercooler style (requires mounting
the core, water lines, water tank, water pump, additional radiator, wiring etc.)
Don’t forget the added maintenance of servicing all those components.
The water pump will draw additional power away from the engine. This causes
an actual loss in power over stock in the lower portions of the rpm band.
Dyno results comparing the air-to-air and water-to-air intercoolers show less
than a 2 hp gain (If any) over our air to air and only at specific rpms! (Note:
our intercooler shows higher gains across the entire rpm band.)
Water to air produces the additional 2hp at 6800-7200 rpm only. While a loss
in hp from stock is noted below 4500 rpm with water to air intercoolers.)
Dyno results on otherwise stock mini cooper s show 7 hp and 5 ft/lbs torque
at the wheels from 2000 rpm to redline and beyond. Modified cars (pulley, intake
and exhaust) produce an additional 9-11 hp and 7-9 ft/lbs torque.
