Harley Turbo

RB Racing's Turbo Harley in full view. You can see the 2 1/2" diameter low restriction turbo discharge tail pipe. The turbo "chops" up the big twin's "potato, potato, potato" sound so well no restrictive mufflers are needed. Dogs may love trucks but turbos hate mufflers. The turbo cross-over or connector pipe is just visible over the RSR "black box" or ECU. The ECU and the intercooler are mounted in a "pod". Flexible black silicone bellows connect one end of the cross-over pipe to the turbo and the intercooler discharge to the inlet plenum, allowing for movement in rubber-mounted FXR/Dyna chassis. Bonneville or boulevard take your choice. The oil spot in the foreground is from a Honda.
