Individual Throttle Bodies - Wrenchin'

Read about the history, theory and hardware of individual throttle bodies and how to install one in the Wrenchin' section of this month's issue.Individual Throttle Bodies
Often taken for granted, producing power from a naturally aspirated engine is difficult. Simply put, there are fewer options when compared to forced induction applications where, often times, all that's required is more boost and more fuel. To harness ever last bit of power, each part of the system must be scrutinized. Long used by racing engineers for generating more power from all-motor setups, ITBs, (individual throttle bodies) have become all but commonplace within the Honda world. But similar to how different turbochargers and superchargers can differ from one another dramatically, not all ITBs are the same. John Whatley, Nalani Whatley's all-motor drag racing team's crew chief, knows this, as he's tested numerous throttle body configurations as of late. The team's most recent showdown: its current TWM Induction 54mm configuration versus Kinsler Fuel Injection's legendary 62mm ITBs.
