Product Details

Description

Garrett Powermax™ direct fit performance charge air cooler for the 2015+ BMW M3 and M4 boasts a 47%
larger core with dual pass coolant flows to help reduce intake manifold temperatures by an average of 10 °F.
CFD-optimized end tanks improve airflow through the core. An average increase of 12.4 horsepower and 4.9 lb-ft of torque was measured during back-to-back dyno pulls. This direct-fit performance intercooler installs in 1.5 hours and reuses the stock bolts, hoses, and clamps.

Performance Dyno Testing

We performed a vehicle dyno test to gather data comparing the OE to the Garrett intercooler. Multiple back-to-back dyno pulls measure intercooler effectiveness by comparing horsepower output, inlet and outlet temps, and OBD II data.

  • The engine gains 12.4 horsepower and 4.9 lb-ft of torque on average after heat soak (10th pull)
  • The engine gains 18.7 horsepower and 6.4 lb-ft of torque at the 15th pull

CFD Optimization

  • The CFD-optimized design allows Garrett engineers to improve flow distribution through the end tanks.
  • The charge air flow shown in the chart depicts air flow per passage
  • The variation is ~7% from the mean flow

Thermal Data

  • Garrett intercooler outlet temp is ~5 °F lower each run before heat soak
  • OE intercooler has 90% instantaneous effectiveness
  • Garrett intercooler has 92% instantaneous effectiveness
  • Garrett intercooler outlet temperature is ~10 °F lower after heat soak
  • At heat soak, outlet temperature drops by 10 °F

OBD II Data

  • After heat soak, charge air flow rate and pressure increase
  • ~2 lb/min higher charge air flow rate after 10th pull
  • ~1.5 psi higher charge air pressure after the 10th run
