Charge Cooling Data Comparison

B58 Wagner Charge cooling study

The B58 Gen 2 is a solid platform and with simple modifications can make great power.  One of the few weaknesses, though, is the integrated charge cooler.  It is simply unable to keep up with the increasing air temperature coming out of  the turbo as boost levels rise.  This picture shows the Wagner charge cooler on the left, and stock charge cooler on the right.  The green is the air temperature after the cooler; you can see that over a single gear, the stock cooler cannot maintain reasonable air temps.  The Wagner is so much better that over a single gear, temps don't increase at all, and even when compared over multiple gears as shown hear, temps only increase 1c* over a long pull.  Generally, a multi-gear pull would see much higher IAT's than a quick, single gear pull.

Here you can see a Wagner charge cooler before and after dyno; blue is stock charge cooler, and green is the Wagner charge cooler. No other changes, no tuning changes, and the difference will be even larger with optimization.
