WESTACH EGT pyrometer boost gauge
I mounted a WESTACH combo gauge EGT/Boost pressure. Westach was great; they even coloured the temperature scale green/yellow/red as per my specs.
K-Probe with 1/8 NPT fitting is pre-turbo in the rear half of the common manifold. Boost fitting threaded into the 1/8 hole in the intake manifold that was closed with a pipe plug. Very convenient.
The stock wire length of the K-Probe is just not long enough to get to the pod. An extension should be ordered with the probe. The boost hose is plenty long.
I did not have time tonight to hook up the gauge lighting and paint the pod. Pod sits on the steering column, attached by a stainless steel worm clamp. Yes, it needs paint.
Turned fuel up; I get boost under load up to 14-15 psi and EGT can climb to 1200. Hauled 4 tons of gravel and having the instrument was interesting.
I was wrong 50% of the time when I "felt" the engine was working hard and thought I was on top of things.
EGT can get real high quickly and I did not even suspect it.
The EGT gauge is a crystal clear pointer...lift the foot a smidgen and watch the EGT drop.
If you are interested, here is some parts info:
- Gauge: 3C86T9; modified to show green colour from 400-1000, yellow from 1000-1200 and red from 1200 to 1800.
- hose and wires 10ft (standard is 7ft)
- matching K- thermocouple 1/8 NPT
- 329-24 resister for 24 volts to run the lights
I dealt with "Pete" from Westach who was nice and knowledgeable.
