Propane Injection Turbo's

Has anyone ever ran propane injection turbos on a DSM? i have seen the diesel guys do it(for obvious reasons), and i have also seen the Grand National guys run them.

What is a propane injection turbo? I know what a turbo is, and what a propane injection setup is, but not what you mention above :wink: IF you are refering to a propane injection kit, Import Power Online sells the most popular one. I'm personally sick an tired of running race gas, and may try my luck with 93 and propane since I run so fast on pump anyway. The MAF Translator also has an auxiliary fuel compensation knob so I can have it automatically lean out when the propane is activated. I can also set my "low" boost for 20 psi, and high for ~28, with the propane boost switch set to something in the middle, like 24 psi, so when I switch to high boost it automatically activates the proane injection and MAFt compensation. But now I'm just rambling...

Try the Toluene octane booster method yet? I've read a few articles on the subject. Its much cheaper than race gas and no adverse affects on the fuel system. And your local Home Depot has it for fairly cheap. :biggrin: I'm personally gonna use that and an Air/Water IC setup when I get the Galant built. Everybody's so into these huge FMICs , but I think the WRX guys have the right idea. A/W ICs don't require the miles of pipe FMICs do , and A/W IC efficiency is MUCH higher than A/A. Propane sounds kinda like NOS , the cheaters method. Sorry , thats just how I look at it.:cool:

Well what is it? I've never heard of it before.

it is when you set up a propane tank to inject into the motor to be mixed the gas and air mix(like N2O) to reduce knock and detonation.

I reckon that people who are serious & rebuild engines, uprate turbos, etc then use NOS as that extra edge are fair enough - it's the people who do a cheap NOS plmub-in, then think running it on a standard engine is really clever [when really we all know it'll blow up pretty quick] that get my goat :mad:

i am not sure how you form that opion . propanes main purpose is to reduse knock. IMO thats like saying useing higher octane gas oroctane booster(which you recomended in the begining of your response),or a front mount I/C is "cheating". this things were designed for the better health of turbo or high compression motors. i am not trying to start anything because you seem to know what your talking about any other time you post on this board but i am just wondering how you form opion

Yeah , :thefinger them guys........... But I still prefer not using NOS at all. To me its got no place in a true performance motor.

Then why not simply USE another octane boosting method. Plumbing in Propane to reduce knock sounds like a needless and expensive task that something else can more effectively handle. Bigger FMIC's , Water injection , A/W intercoolers ....... can all accomplish the same thing for far less weight and money..........:wink:

Propane is effectively 110 octane. ITs the same thing as when I dump in race fuel (except I use 117 octane) but much less of a pain in the ass with draining the tank at the beginning and end of hte night. Plus with propane its always there, on teh street, and a months worth of it is only 2-3 bucks. I think its pretty slick. The 3s guys have been making tons of power on it for some time now, some GNs too. I think nitrous is a pain in the ass,but when you start looking for nines, the turbo required to do that will often require nitrous to reduce lag enough to get a good et to trap ratio. Not including sick bastards like curt brown though running 9s on a red... :lol:

Air to liquid ICs are ok, but remmeber it takes longer to move heat energy into or out of water than air. then once that heat is in the water, its harder to get rid of it. In my ex's 00 si, the IC had lots of plumbing to get the water up to the front mounted heat exhanger to remove the heat from the water. :wink: Plus the pump, reservior, etc. I'd rather run my 2 short IC pipes than all that BS IMO. In her case it was a solution to a more complex packaging issue, and that is all. Efficiency gets better with some ice water tossed in there, but that doesnt help when i pull up next to her at a light :wink: On a DSM a large FMIC is still the way to go, IMO.

a friend of mine is running alchohol injection into his upper IC pipe..very slick and runs 30psi has spiked 35 and no damage (his car runs in the 9s) he sells kits for 400 and i hear nothing but good about them :icon16: :bigthumb:

Its hard to explain my beleifs in what's cheating and what's not . I used to be of the opinion that anything other than direct bolt-ons (like turbo's) were cheating. Now I'm of the opinion that "fuel enhancers" (such as Nitrous and propane) are considered cheating and needlessly complex to plumb and maintain. Not to mention the extra weight of the tank(s) is completely undesirable. Thats just my opinion :cheers:

Why do you drain the tank at the end of the night? I've never seen anyone do that here. They just mix regular street and race gas all the time and just detune the car accordingly.

Air to liquid ICs are ok, but remmeber it takes longer to move heat energy into or out of water than air. then once that heat is in the water, its harder to get rid of it. Not from the systems I've seen on the Scoobies. Heat is easily removed with a small oil-cooler sized external radiator . And heat stays fairly constant on the street , unlike with FMIC's getting heat soaked at stoplights on hot days. In my ex's 00 si, the IC had lots of plumbing to get the water up to the front mounted heat exhanger to remove the heat from the water. :wink: Plus the pump, reservior, etc. I'd rather run my 2 short IC pipes than all that BS IMO. Maybe you would , but I'd rather eliminate the IC and piping altogether and have a small compact unit on the passenger side between the turbo and the intake. It would be easy to heat-shield it from the rest of the engine compartment and is a lot lighter than the biger FMIC's and associated piping In her case it was a solution to a more complex packaging issue, and that is all.

Nice to see this crappy website can't even include the entire post.........:rolleyes: Oh well.

In order to get the full octane of your race fuel you have to drain the pump gas out. OTherwise its just a mix, and it will be different everytime. At the end of the night we pump it back out for two reasons. One is so you arent running lead for the next couple tanks (I go through enough o2 sensors as it is, one per year). The other reason is cost. Race gas is almost 8 bucks a gallon. If I drain it ack out I get 4 of the 5 gallons I put in back out. So each night I go to the track, I only buy one gallon of gas :wink: This is how everyone up here does it. Just put a 6 foot length of fuel hose on the regulator and turn the pump on. The pump will drain the tank in 3 or 4 minutes. But I still think its a pain in the ass.

You can go to the track and only use 1 gallon of gas? And you do this every night? how often do you go? We don't get many track days here , but its an all day thing when we do. Ive never wasted my money buying racegas , so I don't know what it costs. I prefer the Toluene octane booster method....:wink:

I get 5-8 runs a night, and I'll use a gallon. Wed and Fri is street night, last sat of each month is an Import event. Some local guys running more data aquisition equipment than most people would ever want in thier car have tried the toulene/xylene and found its not quite as effective as true race gas. I dont dont mind paying for the good stuff, I just get tired of all the extra time it takes to setup the car to racem then seutp it up for the 2 hour drive home. Between the fuel, fuel and timing setings, air pressure in the tires, boost setting, headlight, rev limits, fussing with the spare tire, etc, its a hassle when you go once or twice a week. Thre times if theres an even that weekend... lol

Yeah , we do T&T nights every Wednesday only. The only real "events" we ever get are IDRC. Nothing else at Bandimere concerns me , I don't waste time or money on spectator only events like Top-Fuel...........:rolleyes:

Same here. I only went to the track once without racing my car, and I hated every single minute of it. :wink:

well it has taken me a while to get pack online...f*ucking computers lol... any way i wasnt exactly sure on how the propane injection setup worked, i do in theory and what it is suppost to allow you to do, but anyway i feel that it is a really easy and cheap way to safley run extremly high boost on pump gas, and as far as RockinWRX's opinion of it being cheating i dont agree with. i get pissed at the people that put nitrous in a totally stock car and think that they are fast, but if he uses an octane boost to achieve the same over all goal isn't he cheating also?? thats just my opinion. i thought it was a cool modification to perform to any car that could actually benefit from it. and wondered if any one made a kit to do with. i think someone listed one earlier. and someone mentioned an alcohol injection into the upper I/C pipe, i assume that is also to prevent detonation/knock?

They did some tests on 3kgt or stealth and got rid of a lot of knock, and were able to rn more boost. they show clips from the datalogger there. There is a pretty big thread on it at either talk or tuners.

And you're of course entitled to your opinion , as am I. I don't consider it cheating if its in the regular gas tank. Its the stand-alone fuel enrichment/NOS/Propane etc fuel systems that I consider cheating. I prefer my engines making straight power with no help from those kind of things. Converting an engine to run propane ALL the time , would be a different story. Then that would considered its primary fuel source. To me it just means a lot more if a car runs 10's WITHOUT NOS or etc , then it would if it does WITH..........:bigthumb:
