Westach Gauges Installed - Readings

[RJOL]

Just finished installing my Westach EGT/Boost and Fuel Pressure gauges and thought I'd pass on the readings.



This is a totally stock 2001 CTD with just over 15,000 miles on it. The EGT probe was installed pre-turbo; the Fuel Pressure sender was installed on the injector fuel inlet banjo bolt, using the tapped bolt from Geno's to replace the stock bolt; the Boost gauge was installed using the 3/4" manifold port, just aft of the fuel filter, with a 3/4" to 1/8" NPT reducer.



All wires and boost hose were routed through the large rubber grommet in the firewall near the stearing column. They run up the driver's sidewall and into the dual Auto Meter pillar mount.



Here are the post installation readings:



Idle: 13 FP; 0-1 Boost; 200 EGT



Steady 65: 9 FP; 3-4 Boost; 500-600 EGT



WOT on a small hill (in 5th): 7-8 FP; Monmentary 17-18 Boost; 700-800 EGT



Boost never goes above 18... and bleeds down rapidly to about 9-10 as truck accelerates.



I'm planning a trip, over the mountains, in September, and will report on the readings, while towing an 11,000lb fifth wheel, if significant.



Hope this is helpful...

Fuel Pressure

RJOL,



Readings sound just about right, how many miles on the fuel filter, pressure might be just a bit low?

Dave,



Just replaced the fuel filter at 15000. Wanted to install the FP gauge just after that, so I would have a good baseline. If the pressure starts to drop, in a few more thousand miles, I'll consider changing the filter again.

Newly Installed Westach Fuel Pressure Readings

I just installed a Westach Fuel Pressure Gauge today. My readings unfortunately were not even that high.



Idle is consistently at 9 PSI

Normal Driving is about 7 PSI

WOT Thottle will bring it down to 3 PSI



Not exactly what I would like to see!!! Maybe the ground wire connection is not as good as it should be, causing the gauge to read low (wishful thinking).



My fuel filter was replaced just 2000 miles ago
