Has anyone every used one of those propane injection kits that boast 60% increase in HP and 60% increase in torque...and big fuel mileage increase?

 

Well, I don't know about 60% increase, but for most vehicles with a turbo you will see at least a 20-25% increase in torque and horsepower. Mileage can be increased about 1-3 mpg.

 

Have you actually tried this....will it hurt the engine at all?

 

I know several guys that have them and I am getting ready to install my own system on my truck. 30-50% increase in Torque on one of these IDI's isn't unreasonable. No it doesn't hurt the engine it's actually good for it. Diesel fuel only burns about 75% in the engine and leaves carbon and junk in the engine which increases wear and tear on the engine. Propane acts like a catalyst which makes the fuel burn 100% so you therefore get more power and fuel mileage. PM me if you have anymore questions.

 

What is the price for a kit like that.. any online shop i can take a look at it??

 

Look up Power Shot 2000 on the net...........

 

I put propane on my 1984 6.9L NA IDI about a month ago and even on the NA it makes a heck of a difference in power! I built my own system similar to Ziggster's system (do a search for his name, should pull up his write-up). Power comes on strong but VERY smooth, no hard hit like nitrous. EGT's on mine only rise approx. 50-100 degrees when the propane is flowing, BUT it keeps my EGT's down lower on long hills than if I run up them with diesel fuel only! It makes the truck accelerate like a gasser when the propane is flowing!

Has anyone out there had any bad experiences with these propane injection kits? Or does anyone think they are a bad idea?

For those that do have them....Do you run them all the time?

 

I'm interested in putting in a system in my 89 250 7.3, tried to find Ziggster's plan online figuring it would be cheaper building one but couldnt find his plan. any help on finding plans to build this would be appreciated.
thanks all

 

i built a propane injectoin system for my truck and it didn't do anything for power. maybe i built it wrong, or my timing is off or something. because all it did was blow more smoke and if you turn the propane up too much it just clatter like a gasser with about 65 degrees timing. i had my fuel turned up about 5/8 turn and i thought it was too much for the propane to do anything, so i turned it back down and it just don't smoke as much. the truck alredy runs 0-60 in 15 seconds, maybe thats all the old ford will do with no turbo! i got 4.10's also. 0-30 time is like 2-3 seconds! that hoe JUMPS. i still want to retard my timing and see if that helps with the propane. i just used a propane bottle with an acetylene regulator and in the intake i put a piece of copper tubing crimped on the end with 3 small holes drilled in it. if you turn the regulator up to about 15 psi, you could turn the key off and the motor would still run about 1500 rpm's!!!!

 

I was going to try something simpler without hooking anything to the throttle like ziggster. If I was real fancy I might use something to switch it on and off without turning the propane bottle valve off every time.

 

89Ford73, maybe you just answered your propane problem! You said that you have 3 small holes in the copper tubing in the air cleaner for the propane to flow through, maybe it just needs to be opened up more. I have 12 - 1/16th" holes in mine and a friend of mine has 14 - 1/8" holes in his and we have both had good results. Might wanna try drilling a few more holes in the tubing to allow for more propane volume to flow (pressure = flow through a restriction).

Just a thought.

Anyone with questions should send a personal message to Powershotone (here on FTE), who makes the 2000 system. He knows it all and can tell you about everyting.
The 2000 is pretty pricey though, running around 800 or something like that. It is also the best kit available though...

 

How often do you need to re-fill the propane tank? Is it practicle to use full time, or do you use it only when towing?

 

hey, does anyone know exactly if when you push the throttle. does the timing advance or retard?? i can't see any way it would advance the timing. the pump turns to the right. the "advance lever" is on the right side of the pump. it pushes the lever to the right on top when you mash the gas. the lever is hinged in the middle and gets pushed to the left on bottom, this turns the internal rack-ring inside the ump to the right. if the pump runs to the right, and the lever pushes it to the right more when the pedal is to the floor. that means that the timing is being retarded when the pedal is on the floor. retarded timing. right or wrong. why is the pump retarding the timing and would it run any better if you made it advance the timing instead of retarding it???? i could be all wrong.
and i will try putting more holes in there. my tube i don't think is long enough to put 12 holes in it! do i put 6 in the front and 6 in the back? it definately makes more noise, but thats it. do your trucks make more noise clatter like when you hit the propane?
