A 13 row cooler should be adequate to cool most naturally aspirated engines & Turbo up to around 350bhp (FOR TRACK USE) given an installation with good airflow, after this a larger cooler will be required. For road use a 13 row cooler is usually fine for up to appox 400bhp for all but extreme conditions, after this a larger cooler will be required.
Exact cooler size required depends upon: the type of use, ambient temperature, spec of the engine (internal friction, rev range, power etc), airflow through the cooler and over the sump. If you are using your car for any form of track, competition or high performance use then the engine oil will need cooling. The most common cause of competition / high performance engine failure is loss of oil pressure, as the oil heats up it becomes thinner. This lowers the pressure produced by the pump and increases the oil escape from the bearings lowering the overall pressure further still.
Roughly speaking you need about 10psi of oil pressure per 1000rpm. e.g. 7000rpm requires 70psi oil pressure. If the pump cannot meet this demand when the oil is hot/thin engine failure will result - usually in the form of running a crank bearing (death rattle) or throwing a rod through the side of the block! This is especially important on part worn engines - a cooler/thicker oil will give the oil pump a fighting good chance of meeting the demand. On a new or part worn engine if the oil pressure is maintained, the engine isnt over revved or over heated there is no reason for failure.
For track, competition or high preformance use a rough target temperature for the oil is around 100degrees C. Over 100C the oil thins out rapidly and therefore drops the pressure. TURBO SYSTEMS WILL ROCKET THE OIL TEMPERATURE. In very cold/wet weather over cooling of the oil can be avoided by the addition of a thermostat built into the sandwich plate. This oil cooler kit is designed for motorsport use. NO instuctions are included.
