LOL, im the same way...might have to look into one of those

j/k, but i cant see w/o my googles.

 

Isspro has another pyrometer with post turbo color coding as well.




From my understanding of Banks location for the thermocouple the second one would be correct in that application.

 

My tranny guy - highly regarded in the Charleston, SC area, pulled my Banks Trans Commander out of the loop when he rebuilt my tranny a couple months ago. He simply does not like those units - he increased line pressure internally in my rebuild, as well as doing some other nice upgrades in the gear box. I guess if you are not having the tranny torn into then there really is no other way to increase hydraulic pressure than to use an external controller.

 

banks mounts the thermocouple pre-turbo. but it is within 6 inches of the turbo, instead of in the manifolds.

 

The no power pyrometer works just like the using the glow plugs to super tune the engine does.

All the pyrometer does is change the millivolts to a temperature reading.

Most of the old Isspro pyrometers used in large diesels had no power going to them except for the lighting.

 

I have a VDO pyro that came with my ATS 088 kit (used). It too is powered only by the thermocouple except for the lighting.

Just out of curiousity, what sort of boost are you guys getting with those banks turbos (and at what RPM?)?

 

FYI- they call that a "short sweep" gauge

 

At high altitudes, I used to see up to 12 psi. At sea level, it depends on load but generally 8-10 max with grain wagons hooked up. Usually no more than 6-8 solo. I have never turned my fuel back up from when I lived at 5000 feet, which could account for that. Within a couple of weeks, I will be installing a 4-inch system on the truck as a test, spliced into the 3-inch downpipe as far forward as we can get (the turbo outlet is 3-inch). Four inches is probably more than the truck can use but at least a bigger system thatn it needs doesn't hurt a TD like it can an NA. I will also be able to get it on the dyno again soon thereafter, but I doubt I'll see anything. By the way, I am no longer going to upgrade to 3.55s. I have another, much newer, truck that gets better GAS mileage and I drive that one on trips now. I haven't minded paying 90 cents a gallon less and getting 16 or 17 mpg versus 13-14 on the old man.

 

Speaking of which, here's the old man breaking a little snow on our lane and a shot of the old Banks system.

 

Unloaded on a hill I can push around 6 psi if I shift down and stand on it. EGT's never break 1000.

Pulling a load on the same hill (up to around 6k-7k lbs) I can get up into the 10-12 psi range - but can't hold it there too long before the EGT's start getting up into the 1100-1200 range.

Interesting Jim, but your airbox has much more rounded edges and seems a little smaller than mine...

 

Jim, if I'm not mistaken, it looks like that AC is an add on, nicely done.


For boost I am usually maxing at 6-7 psi. For towing, I really don't move that much weight, but I doubt it would have that big a difference, I've taken on 10% grades at full power and see the same results. By RPM, I am under 5 psi below 2000 PRM, at 2500, I can see 7 psi, not sure what would happen at higher RPM, since I never go above 2500 (no need).

I have maxed the fuel out once and got close to 15 psi, but the smoke was ridiculous, so I turned it back down. Now just a slight haze when I tromp on it.

For EGTs, I have noticed similar results. Bear in mind I don't tow a lot of weight, but for cruising at 70 or even 80 MPH with 2-4% grades, it holds steady at 600, and for that 10% grade, maybe 850-900 by the top.

 

David85: The way I recall it, the only way you could get AC on an XL was via a dealer installed kit. I know that my truck's AC is a dealer installed kit. It was pretty inadequate when traveling in Arizona or New Mexico in the summer. Works OK if it's not blistering out. I had a neighbor with a an '86 F250HD 4x4 XLT Lariat and it had a much better AC system. Lots more creature comforts to boot.

 

I see...... that compressor does look familiar. I saw one just like it under the hood of a 2.3L diesel ranger once, that was likely an add on too.

My F250 seems to have come with every factory option, was quite supprised when I realized just how luxurious the 1980s trucks could be.



I added the leather seats, originally it came with a cloth bench seat.

 

Geez, David, it looks like a Bordello in there compared to my truck!
