Alta Classic Top Mount Intercooler for 02-06 Mini Cooper S
Alta Mini Performance Classic Top Mount Intercooler
Alta Mini Performance Classic Top Mount Intercooler
A 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. The Alta Performance air-to-air intercooler is 100% larger than the factory unit, but it still fits under the factory hood with no cutting or trimming even though size is nearly doubled. Overall internal volume is increased by over 40%. Included 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%. While water-to-air intercoolers may be an alternative to air-to-air don’t be fooled by false promises of huge gains over this 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: Alta's 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 an 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.
