Power Wagon injectors, and off highway fuel questions

[Archive]

Hello everybody,I am new to the board and had a few questions. First off, will off road diesel hurt our engines because of the high sulfer content? Or is it the same as the "legal" fuel, only red?
Also, what is the exact Cummins part number of the famous power wagon injectors? What kinda performance gain (horsepower and torque) will I get with these on a stock engine with no muffler? So far it put 125hp to the ground. Later.

Dan,

Actually, off road diesel is much better for our engines because of its raised lubricity and BTU content per volume. THe process used to remove the sulfur also removes some of the lubricity. But there is a catch- if you get caught, it is a he!! of a fine.

Since I don't think we can post part #s, I will email them to you for the PW injectors. Or you can go to Wentland Diesel's website. They have them very reasonable. I have heard of gaining about 40-50 hp, depending on pump settings. They are rated for a marine application at 180 hp, with timing severely retarded in realtion to the pickup app.

Supposedly off road diesel gives better power than the fuel available for highway travel. If you get nailed for having diesel fuel with dye in it you will get fined. I believe this is because the on road stuff is taxed differently than the off road fuel. I'm sure with the push for lower diesel emissions today, that people would frown upon high sulfur fuel being dispensed for highway applications. Some of the logging truckers up here run it when they get a chance and claim more horsepower from it. If you run a tank let us know if you get a significant increase in performance. Just a thought, but has anyone run biodiesel in their trucks(it is made from canola or rapeseed oil) Two cummins trucks at the University of Idaho are presently running on this. It smells like french fries when they go by. The engineering faculty claims that this fuel has almost the same BTU's as #2 diesel.

My truck with the pw's put 242hp and 610 ftlbs to the ground with some other mods. But the new Lucas injectors that BD is selling are much better, but they smoke a little.

Guys: The red fuel is the same stuff as highway fuel, low sulfur content, NO HIGHWAY TAX PAID. Blue (looks green in Fuel) is high sulfur content, and the only one to have any additional lube value. Don't get caught on the highway with red or blue.

I have had the experience of using the dyed, off-road fuel in a 1985 VW Jetta Diesel (turbo, fuel cranked, wastegate shut down) and it sure does have the power with it. I just used because I was on empty and the farm tank was the closest thing. I have even ran a bit in the Cummins, but just on the farm, not on the road. Exhaust smelled a bit different, but I didn't work it hard enough to see if there was any power difference. I have a friend who is a diesel mechanic with 40+ years of experience and he said the high sulfer off-road fuel is better than the cheap crap at most of the filling stations. Currently I run the local Co-op's Diesel RX 9 road fuel and really like it. Never had a gel up yet, even at -26*F. In an engines class at Purdue we did an experiment with corn cooking oil and it had about 85% (I think) of the BTU's that straight diesel fuel has. Soydiesel is even higher. Hope that helps.

Last year I ran some Jet A in my 89. We were sumping some fuel from the tanks of a DC-10 for maintenance, and were going to pay someone $2. 00 per gallon for Haz Mat disposal fee to get rid of the stuff. I put a 55 gal drum of it on a forklift, and raised it up so I could siphon it into my truck. The truck ran good on it, and I could not beat the price (free). In fact, we ran all of our Diesel powered ground support equipment on Jet A, without any additives, and never had a problem.

Well guys, in the last two days the price of fuel here in Vancouver Wa. has went from $1. 79 to $1. 69 a gallon. I can get the red fuel for $1. 40 a gallon, and I am thinking for that little of savings it probably is not worth it. (getting busted!! $$)

As far as the injectors, my engine is stock exept for a k&n, and straight piped stock exaust. I would be happy with a little more horsepower and like 500 foot pounds torque. Would the injectors by themselves make that power on a stock fuel setting? Would I need an EGT gauge?

Later.

Dan,

I think the injectors will net around 230 at the flywheel with a stock setting (or so I have read). It takes a little turn of the screw to get 250. As for a guage, I like to think of it as cheap insurance- $180 for a pyro and boost guage. One more thing- get a 40-50 psi guage. With the PWs and some tweaking, you could top 30 psi under a hard load, even with a stock housing. Throw in a 16 or 14 housing, and it will increase farther yet.

Yeah, I 2nd the injectors. I got over 30 psi unloaded with just the PW's and some pump tuning. Get a different housing and then watch the boost gauge! and the "seat of pants" gauge!

Also, I wonder if my auto trans. will hold up to the extra power? I guess during the gear changes I could lift so I don't slip the trans.

Go with the PWs for modest safe upgrade. I have installed them on one truck without
gauges, but did not feel comfortable doing it. I refused to turn the pump up any more than stock until the customer gets gauges installed. A little pump tuning with a 16cm2 housing and free flowing exhaust should get an easy 230hp, 600 ft. torque. Gauges are a must!

Look to BD for trans upgrades. Modest fuel application from your foot will make the
trans last, but in the long run it WILL have to be upgraded.
