Heat Exchanger

Some may ask why change the heat exchanger and not the intercooler itself? Wouldn't it be more beneficial to go directly to the source of the charge air? The simple answer is yes, but at a cost. The stock system cools the intake charge by using a water-to-air intercooler, an expensive piece to engineer. The cooling circuit for the water that feeds the intercooler uses a primary cooler (heat exchanger) and a smaller secondary cooler in front of the passenger side wheel. Through rigorous testing of all 3 of those components and multiple combinations therein, it was discovered that the most effective performance per dollar solution was replacing the heat exchanger with a larger unit.

F80/F82/F83/F87

• 40mm thick Dinan cooler vs. 24mm thick stock cooler
• 60% more core volume & 19% more face area than stock
• 9° average water termperature reduction to the intercooler across the RPM range. Colder water improves intercooler efficiency and allows the intake air to be cooled by an additional 6° average across the RPM range compared to stock
• More Power: Consistent +10 HP / +20 LB-FT of torque on the stock engine tune
• Rubber mounted for vibration isolation
• Significant reduction in tendency to heat soak
• Track tested to ensure consistent performance under extreme conditions
