7.3L ECONOLINE VAN performance help

[muns53]

Very cool van!

A 4" turbo-back exhaust and new intake should drop your EGTs pretty well. I know a couple companies that make it for your van for under $400 (aluminized). "Full Boar Exhaust" is one and "Diamond Eye Performance" is another.

You can do-it-yourself a "Tymar" or "NAPA 6637" intake on the van. Check the diesel sites like powerstrokenation and powerstroke.org, etc and you'll get an idea of what's involved. You will have to get creative with tubing bends to fit it under the hood. You could use 4" ID aluminum tubing with rubber gaskets at the bends or 4" ID PVC piping.

I can't find it at the moment, but I know I saw pics of someone who put an intercooler into a 7.3 van. They used a 6.0 superduty intercooler and had to relocate both batteries and the radiator, so it took some doing.

All three of these should decrease your EGTs and improve your mileage.

Keep us posted! I for one am very interested.

I have been running a Pheonix chip on my truck for a while now.
Just last month I was climbing Steven's pass in the truck using stock tune.
EGT was 1000.
I then switched to the 25 HP tow tune.
EGT dropped to 850 and that was on a steeper portion of the grade.
I use this truck to pull a 14k lb 5th wheel camper.
The best tune to use for EGT control (IMO) is the 25hp tune.
You get a little more power than stock tuning, and the EGT drops down by quite a bit.
The other positions on the chip are for more HP.
The 45hp tune gives a lot more power but the EGT pushes 1200 if I let it.
It's only good for short hills.
The 80hp tune is NOT for towing.
