Product Description
Dinan High Performance Heat Exchanger for F8X M2 Competition, M3 & M4
Heat is the enemy of performance. Keep temps down and performance will go up as a result of increased efficiency. It's really as simple as that.
In stock trim, testing made it painfully obvious that cooling was going to hold an even more vital role on the F8x (S55) platform to achieve maximum results. The stock cooling system heat soaks after only 3 pulls and allows the engine air intake temperatures (IAT) to rise dangerously. The ECU must then reduce engine power to prevent detonation. With the Dinan high-performance heat exchanger the vehicle does not heat soak even after 7 pulls; more than twice the effectiveness of a stock setup!
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.
Features:
- More Power: Consistent +10 HP / +20 LB-FT of torque on the stock engine tune
- 60% more core volume & 19% more face area than stock
- 40mm thick Dinan cooler vs. 24mm thick stock cooler
- 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
- Significant reduction in tendency to heat soak
- Rubber mounted for vibration isolation
- Track tested to ensure consistent performance under extreme conditions
