R609 Turbocater
Installation Instructions
A. Thermocouple Installation:
The thermocouple mounts into a ¼” pipe thread. If the exhaust manifold is already drilled and tapped, install the
thermocouple at that location. If none I provided, make a ¾” hole in the exhaust pipe not more than 6” below the
exhaust manifold to exhaust pipe connection and weld the R680 bushing into the exhaust pipe (note that the bushing
should not be installed backwards, the thermocouple will only install into one side of the bushing).
B. Leadwire Installation:
The R660 leadwire assembly and the thermocouple are supplied with screw and ring terminals for assembly
convenience. Connect the longer red leadwire to the red thermocouple wire and the shorter yellow leadwire to the
yellow thermocouple wire with the screws and nuts provided. Cover these connections with the protective sleeves
provided. Route the other end of the R660 leadwire assembly to the turbocator, making sure the leadwire is clear of
obstructions that might cut or otherwise damage it. (If it should become necessary to replace any of the terminal
ends, use only crimp or clamp types. NEVER solder terminals to the wires.
C. Turbo-Boost Airline Installation:
Install the 1/8” tube fitting supplied with the kit into the engine intake manifold tapped opening, and connect one end
of the 1/8” nylon tubing to the fitting. Route the other end of the nylon tubing to the turbocator, making certain it is
routed away from sharp edges and hot spots and that no kinks are made in the line.
D. Turbocator Installation:
The turbocator requires a 3” mounting hole.
Remove the dampening wire across the meter
terminals. Install the 1/8” pipe coupling and the
1/8” tube fitting to the pressure gauge side of the
turbocator. Mount the turbocator through the
instrument panel or use a mounting bracket at the
desired position. Connect the light wires to the
existing instrument light switch (12 VDC).
Connect the R660 leadwire to the meter
terminals, making sure that the yellow leadwire is
connected to the positive (+) terminal and the red
leadwire is connect to the other terminal. (If the
leadwires are connected backwards, the
pyrometer will read backwards). Connect the
nylon tube to the 1/8” tub fitting. Check the
boost-air system for tightness after the engine has
been started.
Notes:
1. If the pyrometer is slow or erratic, check the leadwires and thermocouple with an ohmmeter for continuity and
check the leadwires for resistance (wire resistance is 0.23 ohms per foot per wire). Check also for oil, grease, or
looseness at the terminals. The connections must be clean and tight.
2. The pyrometer is calibrated for use with 6 to 15 foot leadwires.
3. When properly installed, the accuracy of the system will be within 2% at 1200°F under average operating
conditions.
