propane...

[salTy]

Well, new injectors would be a safety precaution but the whole setup is really just a supplement to your fuel system. By injecting propane you can slip by upgrading the injectors and rely on the fuel property of the propane itself. Just remember that you are lowering the intake charge AND adding a higher octane fuel. Be sure to have a high flow pump, AFPR, and logger.

As for tank size I'd stick with a 1.5 gallon Vp. tank (which you can get from Lowes, Home depot, whatever.) And a vapor box would be nice (if you could find one large enough to house the tank). The way we setup it up was to make our own small enclosure out of aluminium and ABS plastic and ran a silicone hose to the outside of the car via the little drain plug whole underneath the wiper fluid reservoir.

I just got my kit today. I will post pics of the kit itself later tonight.

From what I recall on the Talon Digest a few years back, water has the added ability to keep your combustion chambers clean. This works in the same way that 'steam cleaning' works. It removes some carbon depsosits on the pistons, valves, and cc walls. Water, however, does NOT increase your octane rating. It simply cools the mixture enough for you to run more boost. It is not a fuel. Propane is a fuel, and due to its high octance rating and cool temperatures as a phase change occurs, may be better suited for the type of driving we do. Each has its pros/cons. Please correct me if I'm inaccurate in any of these ramblings.

Well this post is already 3 pages and is about propane injection so I think if you want to post about water inj. bring up an old post or start a new one. Believe me I could ramble about whatever but lets keep this post in check.

I feel like throwing my chair across the room because I won't be able to get this stuff for a long time. AND I WANT TO BE ONE OF THE FIRST TO HAVE IT !!!!

What about running this propane system with NOS? I figure if at all possible neither could be put at max potentional but how would they interact together? This whole propane thing is VERY new to me I just heard about it a couple weeks ago and am very interested, how ever I love the little extra kick you get with NOS.

The question is why? Why would you want the headache of trying to tune 2 additional adders? Just run N2O and be done with it. It is a time tested proven product.

Sort of like this?

It can and has been done but I find it in no way practical for our DSMs. Not to mention the negative effects of blowing yourself up. Remember that a compressed fuel (propane) and an oxidizer (nitrous) is a good recipe for blowd up car.

I know I left it at work last night. but I will have pics if my camera battery doesn't run out. I don't have it installed yet (still need a tank) but I can show you the pics of the parts that make it all work.

Cmon John...Pics!

I will expect this to be installed by the time I complete my move across country! Leaving AZ on the 22nd getting to MD on the 25th

What Happened? Pics? Install?

Oh, and nice sig pic

 

[talonted_one]

I have been following this thread wit a lot of intrest and all i have to say is


...L2RTSiAWD you are killing me here.

I am so ready to do this all I am waiting for is an unbiased review for this system.

 

[red91tsiawd]

i've been waiting for a review on this kit from john for awhile now, if its still as good as he said it would be "mr propane" will be getting a call real soon

 

[dave92tsi]

where are the pictures of the setup??

 

[L2RTSiAWD]

Well My car has been having so many nagging issues I haven't put it on yet. I promise I will take pics of kit tonight.

I have had the biggest boost leak so I have to pull the intake manifold off again. As soon as this leak is fixed I will be boosting right,idling right and then installing propane.

Ok guys, I mentioned this over on DSMtalk, and I am SERIOUSLY surprised no one ever touches on this idea.

What about Water Injection and Propane? IPO says Propane is so much better than water, and that water has its limits, but my understanding is that water lowers temps allowing for higher boost, and propane slightly cools the intake charge but allows much higher octane and a slight increase in fuel. The combination of these two almost seems to go hand in hand, and yet I never hear a single person speak of both of them.

Water costs virtually nothing to buy, even the blue washer fluid which is a 50/50 mix of water and alky is only 97 cents a gallon. One gallon should definately last you a full tank of gas if not more. Propane if it costs 2 bucks to fill a tank (where the hell are you filling your tanks for that cheap?) along with water would virtually cost NOTHING. I would love to see 22psi on the street with 93oct and a 16g. I have read reviews on WI and it definately seems possible as people are hitting 20+psi on a big 16g with minimal mods just like mine, with the added benefit of propane's higher octane and more fuel that seems like an extremely achievable goal. This propane kit is 300 shipped, a home made (nicely done, not ghetto rigged) WI kit can cost only 150 very easily (I have about 4 saved links to home made kits by DSMers that are actually very nice and very thought out). So for 450 total and about 3 bucks here and there you can have an absolute beast. Now I want to hear your thoughts.

 

[L2RTSiAWD]

My thought is If I can run 25psi on my L2R on the street(which will snap a rod) I don't need water injection. If I have a built motor and I can run 27-30psi on propane and pump gas why do I need water?

 

[16g-95gsx]

First off, I dont have an L2R, not many people do. We run about 18psi on the street with a small 16g like mine. Therefore we have ALOT of room to work with here .

i have been running propane for a while now and posted in a review at dsmtalk. it would be worth your while to read through it...i have provided some numbers. http://www.dsmtalk.com/forums/showthread.php?threadid=65627&perpage=25&pagenumber=3

(same screen name)
feel free to email or PM me with any questions, i am pretty familiar with this thing by now.

It took my like 30 minutes to read through this whole thread, ... Just a few quick points I havent heard mentioned yet.

When using water injection, you are displacing combustable mixture with water. So at some point of adding more water you reach a point of diminishing return. I think Propanes main advantage is that you are not displacing fuel with water, but with another fuel.

Turbo Diesels have been using propane injection for a long time now. Its been around a while and is proven. They dont make 1000 ft/lbs out of those motors by eating wheaties everyday Propane injection is good stuff. The more data I see for DSMs the happier I will be. I plan to try this out at some point.
