We are all done for when we stop trying to do something because someone tells us that it won't work. Edison said he found a lot of ways NOT to make a light bulb befor he found the right way. SO everybody that trys a different approach is narrowing down the other ways until the best way is found. i'll drink to that,your 100% right

Well said, points to ya topgunn.

It was more than I thought.
You also have to remember, if you were to double your speed you need quadruple the power, so each MPH faster you go the bigger the mirrors become.

The wind resistance difference of the mirrors at 55 and then going 1 mph faster to 56 is not much compared to the wind resistance of the mirrors at 75 and then going 1 mph faster to 76.

After what I read recently, I'd bet if I made the same trip at no faster that 45 mph (the minimum speed for high gear to kick in) I might have gotten up to 30 mpg.

BYW guys, I almost NEVER carry anything other than a spare tire.

I hauled a trailer and a heavy duty mower last weekend and on Tuesday Grammy wants her pine tree in the back yard cut down and hauled away.

You are right about drag increasing, IIRC it increases at square of speed. If you could keep the air from going under your pickup you would probably increase your mileage as well.

FWIW we had a 95 psd (3.55's) that made 21mpg pulling a 30' 5er thru Yellowstone park cruising around 45mph all day long.

Gene:

The only thing I want to clarify here is that what I mentioned in my last post is not MY theory... just a regurgitation of the explanations I've read from others who proposed the theory related to why there are supposed to be lower EGT's when injecting HHO into the PSD intake system.

[tradergem]

I thought that the reason for the lower EGTs was because the HHO burning in the combustion chamber caused more of the diesel to also burn inside the combustion chamber therefore releasing more heat inside the combustion chamber before exiting into the exhaust? Does incompletely burned diesel continue to burn inside the exhaust manifolds?

I thing the effects of HHO are small but many.

A little extra fuel, a little water, a little steam clean action,.... etc

Hydrogen and oxygen burn at 8000 FT/SEC. Technically thats an explosion not a burn. It's like igniting all of the fuel in the cylinder in in less than a second. By the time the exhaust valve opens, all of the fuel is consumed and only the byproducts are pushed out of the cylinder.

Anyone using hydrogen with bio...?

I used to fly on the KC-135A model air refueling tanker; we used water injection when we needed to launch with heavy gross weights; older B-52 bombers did as well. At a certain point of throttle run-up the engines were injected with de-mineralized water (it all depended on outside air temperature & water temperature). You talk about diesel smoke...whoa I'm telling you day would turn into night. This lasted for just a couple minutes during the take-off sequence.

We lost some great vets when the water system failed during a critical phase of flight, i.e. loss of power, not enough airspeed plus too close to the ground.....well you get the picture. V/r Les

Thats really something.

I cant imagine what a wild ride that'd be.

Love the B52s....solid design and still going strong after over 50 years of service. I'm a sucker for old machines that serve that well and that long.

Just a little story to illustrate how wild that ride can be:

Some time ago (actually a long time ago) I was privileged to work on the BUFF as an engine mechanic and later as an engine recovery crew chief.
Part of our function was to run engines after maintenance for checkout, and this included testing the water injection system. Our check list included three critical items....making sure the chocks were in place, setting the parking brakes, and having a firetruck on standby. (The firetruck would motor out to the flight line and park facing the aircraft some 70- 100 feet in front of the nose). Actual testing would then be to run the engines at 80% power, then hit the water switch.

All well and good. So here comes this hotshot recovery chief, (no, not me!),
who proceeds to run all 8 engines up to 80%, and hit the water. Only thing was he skipped one item in the check list- the parking brakes. When the water hit, the aircraft literally jumped the chocks, and by the time he got the water off, the throttles back, and the brakes on. the aircraft was nose to nose with the firetruck. Needless to say the fire crew had to clean the truck of what the crewchief was knee deep in.

Hahaha!!

That sounds like great fun!

Sometimes i wish i woulda done something exciting like that....
