"RAM AIR" or Over The Radiator (OTR) SYSTEMS
The first thing you must understand about this type of system is that "Ram Air" is a marketing phrase. Ram air theory simply does not work in this application. OTR systems do provide as straight a path as is possible to the intake manifold though by ditching the stock intake configuration and doing exactly what the name suggests, they go directly over the radiator. This approach is outstanding from a restriction reduction stand point. Vararam is the best known manufacturer of these types of systems.
The OTR design typically produces solid gains top end gains. However, installation of this type of system requires that the radiator be leaned back which is not ideal for engine cooling. In a race application this can become a big problem but for the typical street car it is not as big of an issue. Also, the placement of the intake opening above the radiator can lead to heat soak and high IATs at low RPMs. Those are the two big things to keep in mind when considering a OTR system.
