Each year at PRI, Innovators West [(785) 825-6166; www.innovatorswest.com] seems to always be at the ready with a slew of new dampeners for 4.6-liter engines. Among the latest hotness is this factory-replacement balancer for '03-'04 Cobras. It's designed for use with the OEM crank-support system on Terminator engines, and it really shines when bigger blowers are added. IW also introduced a 15-percent overdrive balancer for Two-, Three-, and Four-Valve engines. The dampener fills the middle void between the company's 10-percent overdrive street unit and the 18-percent wheel that is used for race applications.
