The new VF620R supercharger system for the E92 2007>2014 M3 V8 features an oversize front water radiator for racers participating in “runway racing”. Often overlooked by designers, cooling systems must be designed with the capacity to sustain full throttle through 4 gears without releasing throttle. It requires tremendous design tolerance not only in the fuel management but also in the charge cooling department.
After extensive data logging with independent thermocouples throughout the air system, VF-Engineers found that upgrading the water cooler radiator kept air temps down through successive gears and not just a dyno pull in a single gear. Analytics can be catered to show benefits of an upgrade, but we put this system to test on 16-19 psi supercharger setups to explore its potential. Positive results meant that we introduced this product immediately for the 6-10psi kits and not just our 17psi fully race built engine kits.
This upgrade is fully compatible for street use kits and available to purchase as an upgrade to replace your existing “street” radiator originally supplied with your VF-Engineering supercharger kit. The radiator shown in the image above is the item described.
