    A wet nitrous system is nice because you get the right amount of fuel to go with the added air charge but with a single nozzle wet system, iv heard and seen that they are a little risky to run. The fuel can "puddle" and blow your intake manifold right through the roof, and other types of major damage could be done. Does anyone know if a direct power system would be any safer? Check this system off a S2000 out, http://www.s2ki.com/forums/index.ph...&f=107&t=225232

    to me, it doesnt look that hard to make a direct system like this one, a little drilling, taping, pipe bending, but would it be any safter than a single nozzle in the intake? Is the direct port system just more efficient?

    Direct port Nitrous is safer than fogging, without a doubt. However, by running propane as the fuel add to nitrous, it becomes very safe and effecient as a fogging application. Its the only way I go, and Ive been running Nitrous for over 20 years. Propane is 114 octane, and no chance of a puddle. You can dial in your A/F mixture with the turn of a screw.

    Well i gotta be honest in saying that i had NO idea that you could use propane on a gas motor. I have seen it used on a deisel though. How exactly do you use it? Do you just plumb the propane to the fuel solenoid on the nitrous system? As far as regulating it, do you just turn the valve on the tank? What things do i have to worry about as for as the motor goes? I heard that if your car has many miles on it and is leaking oil into the combustion chamber, that oil will in affect lower the octan of the fuel and cause detonation. is that true? i have a hunch my 90 LS with 195K miles on it is burning some oil but then again, spraying a motor with 195K miles on it isnt probibly the best idea in the world. what worries would someone have when running nitrous? Are you running a simple fogger setup on your Lamborgini similar to the one on the Viper?

    Propane has been used in Nitrous applications since about 96. The propane is jetted in the same way the Nitrous is. If you increase the Nitrous jet, you go up on the propane. I just pulled my dyno's, and the propane jetting for optimum A/F is about 67% of the Nitrous. Example: A nitrous jet of .62 would have a propane jet of .42. No worries on the motor at all. Here is a link to the very best propane systems on the market.

    What kind of car do you have. I saw 1990 LS. Integra LS or? I can help you out with any questions you have. I own an online shop that sells parts for high performance naturally aspirated cars. We basically modify N/A cars and turbocharge them. I have alot of experience with nitrous and have customers I've sold nitrous to. Let me know what you need and I can help you with any questions.

    Its a 90 Lexus LS400 :) My original question was if a direct port system would be any safer than a single nozzle wet system. But then came the topic of propane which seems to be an easy fix. My main concern is sparying a car with 195K miles on it. What would i need to be sure of before spraying the car? What could happen if the motor isnt in tiptop shape? Also, with propane, would i still need to go one step colder on the spark plug?

    No need to go colder on the plug. Also,The propane system is a dry system. You can buy a generic system and add propane. Nitrous express has a good generic setup. Just call Tom at BTR and pick his brain. Even if you dont buy from him, he will educate you on the ease of the system.

    Direct Port is allways safer, I personally know nothing about the whole propane deal, seems interesting however. I wouldn't spray more then a 75 shot on an LS400 if you want to stay on the safe side. I think your spark plugs are okay as is, I personally wouldn't go any colder. I sell alot of turbo kits/nitrous systems to GS300/IS300/SC300's. Since I have the best bang for buck turbo kit out on the market right now, but I'm not sure if I've ever sold any parts to an LS series. I wish you luck with your project however and keep us updated.
