Turning up fuel screw

[cody mapes]

I have a 94 7.3 factory turbo with a zf5
I wanna turn up the fuel screw for some more power
Do I need a egt gauge?even if I only turn it maybe one or 2 flats

 

[IDIBOBS]

YES. You should always have an egt gauge. Things can go hot very very quickly.

 

[IDIBRONCO]

You should have one even without a turbo.

I probably should stay out of this one but after 50 years of turning wrenches off and on and being around farmers for many of those years and farming myself for over twenty years I have heard many say I want a few more ponies. Usually the most successful at getting those results went out and bought the tractor or truck rated for the HP that they wanted. The ones who turned up the screw usually ended up needing repairs sooner than later.

On 40 year old engines that parts are getting harder to find I personally would try and get as much life out of things as I could. I also have a 94 factory turbo and most of the time I pull a trailer with 150 gallons of red diesel to my fields to fuel tractor or combine. Truck does fine and certainly has more power than the 300K mile 300 6 that it replaced. If I thought I needed more power yet I would find a power stroke but that is just me. And yes back in the day when these trucks were new and I worked in a truck shop I turned up many a screw because that is what the customer wanted.

2 flats is a lot more fuel. Without a gauge you are gambling every time you really open the throttle for an extended period. EGT gauges are much cheaper and easier to install than R&R-ing an engine. I don't have the same turbo as you but I found 1-1.5 flats to be plenty of extra fuel for a daily driver/work truck that's not trying to leave a smoky trail everywhere. Drill a hole in the driver side exhaust manifold towards the firewall. Start with a small drill bit to make a pilot hole, then finish with the proper size bit for whatever size threads you'll be tapping. Grease the bits to capture the shavings then vacuum and/or use a magnet to clean the hole out as best as possible since you don't want metal through the turbo.

As others have said, you should undoubtedly get an EGT gauge.

I would say 2 flats max, if it’s stock otherwise.

With an intercooler and high flow exhaust you should be able to max it out.

Sorry for the derail op.
Hit the stickies, first, then add a pyro.
The reason why they did not put one in is $$$
So TheyJust detuned them to be idiot proof

Been a minute but you made me remember this

You suggest I put the probe in

Thanks for the details

Egt gage

Auber egt gage. How is this wired up? I’m not too great on electrical.

Pyrometer placement

Where is the best place to take EGT readings on the 7.3? The truck currently has a Pyro and the probe is just after the Y-pipe. I get why it was place here but it seems way to far away from the cylinder to be of any use. I have always drilled a manifold? Tapped and installed there on turbo...

New to the IDI? Buying a used one? Read on....

The following is a primer on what to look for in a used Ford truck or van, powered by the 1983 to 1987 6.9 and 1987 to 1994 7.3 IDI (Non-Powerstroke) engine. Obviously any vehicle purchase should include an inspection for the obvious signs of trouble. Leaks, squeaks, obvious damage, bad...
