Historically, other
supercharger designs haven't produced much power on Harley-Davidsons due to
the high parasitic load and hot charge air temperatures they produce.
These hot temperatures not only result in less air density, they rob power
by forcing the reduction of ignition timing. Turbochargers are able to
utilize air to air intercooling and have efficient compressors, but are
subject to extreme heat transfer from their exhaust interface and generate
substantial exhaust back pressure. |
Intercooled ProCharger systems
are the fundamental solution- not only is less heat added when the air is
compressed, less heat is absorbed from the engine and exhaust and the
majority of the remaining heat is removed through an intercooler. Cool
charge air temperatures reduce exposure to detonation and are the key to
maximizing power and engine longevity. ProCharger is the first and
only intercooled centrifugal supercharger system for Harley-Davidsons, and
the only power adder able to deliver these benefits. |
