Lycoming Horizontal Induction Engines
We supply either the 60mm throttle body if you have a sump designed for a carb or an RSA-5 servo,
80mm TB if your sump was designed for an RSA-10 servo. Again, the TPS and throttle arms are already
mounted for you. The 60mm TB snout has a 2.5 inch snout and the 80mm TB has a 3.5 inch ID snout.
Continental O-200 Engines
These use the wide flange 45mm throttle body
Other engines
Engines below 120hp may use our 45mm TB in conjunction with a CNC’d adapter (Jabiru 2200/3300
engines) or bolted directly to a new fabricated or modified stock manifold. All TBs have O-ring sealed
bases and provision for a TPS. Throttle arms are available for vertical, forward or aft facing applications.
10-32 Allen bolts are used to hold the TB to the manifold.
Throttle Position Sensor
If you ordered the TPS option, it will already be installed on your throttle body. Some engines run well
without a TPS. The TPS offers quicker throttle response on most engines from low rpms. Wire color
connections are as follows: Pin 1 orange, Pin 2 blue, Pin 3 white.
MAP Sensor
The MAP sensor may be mounted forward or aft of the firewall. It
should be mounted with the vacuum port facing down to prevent
moisture from collecting inside. Never mount it with the port up.
Join the sensor port to intake manifold or TB ports with 5/32 vacuum
hose. You may tee the MAP sensor hose with MP gauges and fuel
pressure regulator if desired.
