propane injection...who uses it?

the dr kit is pressure activated at 12 psi as well. according to the thread about it in their forums.

That's my point, the DR kit is activated at 12psi at that point it is ON full blast regulated only by the jet size installed. The deisel truck is variable based on PSI. More boost more propane. I think this is better.

oh ok i gotcha, yea that does sound a little bit better

mitgsx · May 30, 2002

Why doesn't someone here just buy diesel performance kit and give feed back. I am debating on propane or a FMIC. I think both would be great, but the way I see it propane would allow more boost by higher octane, more fuel and even cooler intake temps.

eyebrowski · May 30, 2002

the reason i liked the powershot better than the dr kit is b/c of the proportional propane shot to boost pressure.

can i use n20 at the same time as the propane? or can i only use one type of injection at a time?

mitgsx · May 30, 2002

I am just wondering how well it can be controlled? I don't really want a small amount of propane at 5 psi, but I would like it to come on at a set boost pressure and go proportional after that. I think that this would be the dream kit. Now it has me thinking, if you could hook up a pressure switch to the powershot 2000 kit?

import power on · May 30, 2002

The powershot I think is the way to go. The DR is on or off and you pick a jet size like with Nitrous.

But since you are introducing more fuel I would think it would be better to inject it proportionate with boost levels. This is what the Powershot does.

I contacted Powershot about there system here is what they said:

Thank you for inquiring about the Powershot 2000 propane injection system for turbo diesel engines and for the link information.

If the engine has a turbo or supercharger, the Powershot system, which is a variable flow rate system, monitored and controlled by the boost pressure of the engine, will work on it. Propane on a gas engine, helps to control detonation. The tank on a passenger car application would be very small only about a 1-2 gallon tank, (5#) and would have to be mounted, either under the vehicle, in a vented to the lower atmosphere trunk space or in a vapor box.

If you have any further questions or would like any additional information, please do not hesitate to contact me at 800-606-0858.

Again, thank you for your interest.

Sounds like it would work good to me.

I am setting up to be a dealer for Powershot. It is much better than on or off, it is totaly continuously variable. I should have prices soon

Since it comes out as a gas, could you not inject it before the turbo and get a super cooling effect with it going through your turbo and then the intercooler? with it coming out at -40 degrees and all... it shouldnt mess up the blades like if water is injected before the tubro,,, what do you think?

90tsi · Jun 8, 2002

it'd just super heat the propane, and may actually cause pre-ignition of the propane. i mean what is the point of cooling off the compressor blades?? the earlies i could see spraying it is in the lower intercooler pipe. but really it won't really cool off the air that much, you may as well let the intercooler do its work.

mitgsx · Jun 8, 2002

Yeah, let the IC do it's work first. What ever your intake temps are going to be at the TB, they are going to be colder and more dense with some propane. I like the higher octane for the street concept, and cheap too!

I'm hella down and ready to run propane injection, I was soo hooked on SMC's alky kit. I almost bought it. Then I saw dynamicracing com out with this propane injection. First I thought it was a joke and the car woud explode, but man it you tihnk about it it totally makes since and MAV you made a great point, and i wish people would stop thinking this shiz is NOS and start to realize ALL WE ARE TRYING TO DO IS COOL THE AIR CHARGE. Hello people common sense, cold dense air makes hp.
I have one question about all this, is running an open BOV ganna propose a problem. I mean in theory we would be dumping excess propane in the engine bay which see temps of around 200 degrees. humm.... sounds like a problem to me, can someone answer it?

import power on · Jun 16, 2002

I am gettting the system factory tuned/adjusted for my setup this coming week. I will post the outcome. I also am a dealer now and will be selling them.

Better than DR cause this unit it VARIABLE and adjustable.

ss68and66 · Jun 16, 2002

Import Power on you are a dealer of propane injection? Do you have any pics of your set up as well as information on what it includes and how your system works? I am very curious if it's as good as dynamics I might be able to steer a few other people your way (me and a group of friends were lookin to purchase a dynamic racing kit.)

All the more info you can provide would be greatly appriciated

I am a dealer for http://www.dieselperformanceproducts.com/

They are making them special for us Turbo Gas cars. They have a long history in Diesel Turbo trucks. I am talking about getting 700+ lbs of torque with just a chip and Propane.

They take Your motor type, cruise psi, max psi, Est HP and custom calibrate the system for you so that is works out of the box. It is still tuneable to get it just right for you if you wish.

DR's is ON at a pre dtermined PSI. Set it at 16psi, it comes on 100%, stray away from 16psi (lower) and it is off. ON-OFF. This system is variable with the PSI just like your Fuel system. AWSOME! MOnitors tank pressure and keeps it 100% constant for a smooth reliable setup.

I was talking it over with a friend of mine this evening. He owns a VR4 also and is interested in a Dynamic Racing kit. HE was wondering "what if" the preset amound of propane in the dynamic Racing kit is enough to supply a car with, say 12-22 psi, i mean is there really that much of a difference in the amount of propane being dumped into the engine? If a 1.5lb bottle is enough (I tihnk that is what the size is on the small bottle DY sells in there kit) to last for a month or two then this system can't be dumping that much gas, and varying the propane injecting amound can't be that great of a power gain. I mean we aren't dealing with nitromethane here. And we aren't injecting stupid amounds in the engine to begin with. Is it possible to calculate the amount of propane needed to suffecently lower knock to say zero at given psi's. Translated can we calculate how much propane is needed for each psi increase of boost?

import power on · Jun 16, 2002

Yes, it is a big difference. Why shoot 100% at 14psi when you really only need 50%? Same reason you wouldn't want a NON variable fuel supply. Pressure rises as manifold pressure rises. More need, more gas. Same goes for propane, more need, more propane. Why waste it dumping only one set amount on at only 16psi+ when you can vary it?

import power on · Jun 20, 2002

Getting the kit in tomorrow. Just picked up the 5# bottle

GOT my 5# propane tank from Home Depot today. $27.99 You may be able to find something cheaper but I did not feel like shopping around in this heat to save a few bucks.

Here she is:

In car. It is so tight under the seat ledge I can't get it out without folding down the seats. It can move a bit side to side so I will make an aluminum brace for that.
