Installing the Pyrometer
Pre-Turbo
1. Choose the pyrometer location. It should be about 3″
in front of the turbo charger exhaust inlet where all the
exhaust runners of the manifold have come together into a
single pipe. Try to be within 1″ of the 3″ target.
2. Drill a 5 /
16
″ hole into the exhaust system. (See the tool tips
on page 13 for important strategic hints.)
3. Use a 1 /
8
″ pipe tap to thread the hole.
4. Place the pyrometer probe in the hole.
5. Use a 9 /
16
″ wrench to tighten the tapered end of the fitting to
the exhaust downpipe.
6. Use a 5 ⁄
8
″ wrench to tighten the top nut on the pyrometer to
the fitting.
