What more can you ask for when you have luxury combined with state of the art performance? The RGM Supercharged Prado 4.0 is one such vehicle. Modern styling and comfort with the desired horsepower on tap. In our usual professional fashion we have take the Prado a level up by developing a CAD designed supercharged installation, appealing in all senses. The Vortech centrifugal supercharger unit we use is a V2 SC-Trim. This unit is renowned for it’s quite working operation as well as its reliability. It is high pressure oil fed and runs a gravitational oil return to the sump. The charge cooler as well as all other aluminium components have been highly polished. High pressure blue silicon has been employed for boost couplers and other bends. These are secured with Stainless Steel clamps. As the supercharged unit is permanently engaged, the use of the RGM high flow Dump Valve (Recirculation Valve) has been employed to eliminate any surging under light throttle and coasting condition. We have, in this state of the art design used a Liquid charge cooler as opposed to an Air-to-Air intercooler. In extensive testing we have reduced boost air temperature by up to 60 degrees Celsius. An advantage in our installation design utilizing a high quality Setrab cooler, that mounts on the front of the car was that we did not impede on the normal air flow to the radiator. This cooler is also fitted with it’s own 8 inch electrical fan, adding unrestricted airflow to the radiator. This also assist in more effective charge cooling in low speed conditions. The total of the 5.5 litres liquid cooled system is made up of 50% water and 50% Glycol (Anti-freeze).
