I've been curious to what would happen if one would use all three (prop., water/meth, and nitrous) all at the same time? Will the kill the engine? Open up a time warp? What?
Just thinkin out loud.

Probably depends on a few things - what are you trying to do? Improve mileage? Lower EGT's? Boost performance? Lower the cost of operations? All the above?

Any one of the above should be able to do most of what you want by themselves... except for lowering your EGT's - that's the domain of water/meth.

I always take the approach of deciding what problem you're wanting to solve... then looking for the most appropriate solution. If it calls for multiple solutions, it'll probably become apparent.

If you carelessly combine all of the above, you could cause a rift in the space/time continuum, so I would probably avoid that... :D

Interesting. Thanks!

Now say one is on the strip and opens up on everything on the way down?:eek:

Well, somebody who knows these engines better than I will need to weigh in on the topic. I would assume your engine would be toast unless you have a well built high performance engine (stronger pistons, rods, heads, head bolts, etc., etc., etc.)... but what do I know?

I read you can only use water meth until it gets about 0 outside? Is this true? If it is, Im considering putting both kits on my truck. Water meth use in the summer and Propane for the winter. That could be done easily enough? Couldn't it?

Hmmm... that's interesting. Since they (whoever that is) recommend you use windshield washer fluid - and in the winter you typically use the higher level methanol stuff (some of which will withstand -25 degrees) - I would have thought you could use it under 0 degrees. I still don't have a w/m system yet (drat!), but I'd be interested to hear more about this too...

You can use water injection until 0 degrees, because that is when water freezes, you can use water meth until if freezes, or becomes so vicious it doesn't flow. I know labonte and others have suggested only using up to 20 or 25% methanol when using propane or nitrous, so whatever 25% meth and 75% water freezes at should be your cutoff point, until it thaws in the engine bay.

So propane is supose to raise EGTs when used. Im guessing that depends on how much you pump in also? I was thinking for winter use in very cold weather that it would be good to use propane unless towing and under very heavy loads? We all know that Diesels get worse mileage in the winter months. Propane kit sales were slowing down when fuel was about $1.50 cheaper because propane was too close to Diesel pricing making it too expensive to run both. Now that Diesel is going to easily be $5.00 a gallon this winter and propane is $2.20 a gallon now. People are going to start putting those 750 gallon propane tanks like I have n my yard and getting them filled during the summer months and finding a way to fill there tanks off it because propane is $1.00 more in winter months.

The other thing is even though water meth cools egts, it only adds 1-3 mpg and some guys on this site are saying they are getting over 30 mpg with there propane. Some are saying real high numbers when not towing?
That is why Im considering putting on my propane kit when Im not towing and for long trips. 30+ mpg, how can you beat that? At a 1 to 4 propane to fuel ratio how long will the average tank last? I would like to do the math and see what kind of savings if any it would be using propane. One guys said just a dime a gallon. if that true then its not worth it. I found washer fluid (consentrate) for $1.00 a gallon from a trucking company. It has to be mixed with 50% water for a -20 rating. So the meth content is high and then its my choise on what ratio meth I want to run. That makes it .50 a gallon once mixed. So for $3.50 I could fill that snow kits 7 gallon tank that they say will last 1,000 miles if not towing. Thats much cheaper but only a additional 1-3 mpg dont forget. What to do what to do?

Couple of clarifications here. First, water freezes at zero degrees C/32 degrees F - so let's stick to F. Dan Labonte has repeatedly recommended WalMart SuperTech, which is rated for -25 degrees F... but according to Dan that stuff is 38% meth, which is too much meth when using either propane or nitrous.

So... with a cutoff of 25% meth, that figures out to be somewhere near -7 degrees F (-21C). 20% meth figures out to somewhere near zero F (~-18C). Looks like that's where the zero degrees F came from.

There is a guy on the propane injection topic above this one claiming he is running straight propane and getting 60 mpg at 65 mph on level ground. He figures he is saving about a dime per mile not per gallon over straight #2 fuel? Could this be true??? If so why are we all not doing this?

Because he's substituting one fuel for another. Typically, for every gallon of diesel he burns, he's burning +/- 4 gallons of propane. So you have propane to buy, the kit to buy and install, and then you have to find a vehicle-certified propane tank and install it. There are plenty of stories of guys finding vehicle propane tanks for a hundred bucks or less (some even free), but that's atypical. IIRC, the typical cost for setting your truck up for propane is about $1000.

If you don't mind permanently affixing a propane cylinder to the inside of your truck bed, then it's probably not a bad idea. The other thing to consider is that today he may be saving a dime a mile; when diesel falls back again (and it will some day... jut not today or tomorrow) or when propane closes the price differential, then the savings are not near as attractive.

And in reality, you're not saving anything until you recoup your cost of installation, which with a grand in investment and saving a dime a mile would be 10k miles. Obviously you'd be truly saving money much faster if you could buy the kit cheap, get a killer deal on the tank, and buy your propane in bulk, so you might be able to pay for the mod in as little as half that (or better). It is attractive; I'm just hesitant to strap a propane tank in my truck bed.

If #2 prices stay high, I may have to reconsider...

... At a 1 to 4 propane to fuel ratio how long will the average tank last?... \

IIRC The guys at ATS said that their kit will typically last 3 tanks of diesel for one tank of propane...Of course driving conditions and PSI play a roll. Again, IIRC...
