DNN Intercoolers

The system has been engineered to be as direct a replacement as possible to the stock unit, requiring only minor modifications for a clean, factory-like installation. The increased thermal efficiency provided by the Dinan dual core intercooler will also enhance turbocharger reliability in addition to overall power. On a stock vehicle, power gains can be had from 4000 RPM and beyond (when the car is in boost). In order to achieve the best performance, the intercooler should be paired eith engine tuning as it can provide additional optimization of the intercooler. In particular, with Dinan flash software the power band is extended to be more robust and powerful from 5000 RPM to redline whereas without tuning the bulk of the gains are from 6000 RPM to redline. Greater power gains are achieved with a larger high-performance intercooler. The Dinan dual core intercooler provides a 240% increase in face area along with an equally impressive increase in volume, substantially reducing the pressure drop to 0.8 psi, as well as providing for more efficient heat exchange and more consistent output power. Dinan's unique dual-core design allows 2 separate cores to be working in conjunction with one another at all times. This doubling of resources is directly responsible for a 60% improvement in the delta from charge air temperature to ambient temperature (see diagrams). "Cool down" time is also reduced, enabling the cars to produce full power under varying driving conditions such as stop and go traffic. This leaves the chances of being susceptible to heat soak nearly a thing of the past. Dinan High Performance Dual Core Intercooler - 2012-2016 BMW 2/3/4-.
