Introducing real HP gains by Plazmaman - Zero lag , easy no fuss instal , no cutting of body work , instant power gains . This is a bolt on under bonnet kit which sits in the area where the OEM top mount cooler used to sit . A front mounted radiator with thermo fan mounted to it provides all the heat exchange required for this unit . Our initial test vehicle showed inlet temps at 120deg @ 18 psi on a ambient of 30 deg , and after cooling with W2A system air temps were at 39 degs , an astounding 9 deg above ambient , with absolutely no pressure drop . We also found by removing the OEM intercooler , the under bonnet temperatures dropped dramatically as air from the bonnet scoop came filled the engine bay with cooler air . All components are of premium quality and made and tested in house at Plazmaman . This kit is rated at 600 hp capabilty , with the option of 700 and 850 if required at an extra cost .
