Thanks guys,
I did install head studs. I don't know exactly how the propane fumigation effects the engine, but it seems that the propane helps burn the diesel faster, and that should create higher cylinder pressures. There seems to be a good increase in mialage, and power, but I have only run about 1/4 tank of propane so far. I really have not noticed much difference in EGT's. So far all my driving has been without any load. Maybe I will hook up the trailer and see how it works?
Last night raced the truck, and I used the propane at 100%, comming in a 1psi. This is the way the system ships.
I did not get much data, only two time trials before eliminations.
This is what I tried:
With the Edge in 3/3 and the propane, the trucks ET was about the sane as when I ran it without propane last year, but the miles per hour was up.
The truth is that it was just too much power for my stock transmission and turbo. During the run the tack just sat at the govenor speed of about 3,200 RPM through 1,2, and 3rd gear. When I got back I checked the Edge and it was de-fueling also, which it did not do before on level 3.
Anyhow, without a tighter torque converter, it won't help my ETs.
Driving back from the track with the propane still set at 100%, I noticed that it comes on pretty good in stop and go trafic to where you need to be careful not to run up on the car in front of you.
The overhead mialage computer goes nuts when highway driving. It was showing over 50+MPG
In city, stop and go traffic really lowers the the mialage, but I think the combined drive last night still was showing close to 40MPH on the overhead. again, I don't have any real hand calculated numbers for a real comparison.
Anyhow, here is a few pics:
