Diesel water-methanol injection

Have any of the members installed water-methanol injection on their diesel MH? There are a great number of kits available that are supposed to reduce EGT and increase HP/fuel economy. Most of the kits have good reviews on truck installations however I can't find any MH reviews.

I would be interested in any responses to water-methanol. I think it would be a very good mod to do. I have a couple of friends that have done this to their pickups. Works great.

What ever the set up would be on a similar motor in a semi would work with our MH's. Lots of places to put the containers to hold the methanol.

I think that the hardest part will be to run the wiring. Since everything is enclosed in the body ect. However that could be over come with some PVC or electricians pipe and running it under the length of the MH to the dash area for protection.

I am sure you will get some response like why mess up a good stock motor, or the factory sets up the motors for optimum performance. Well all the hot rodder's in us know better. Factory motors are set up for optimum performance based on legal, liability, & warranty issues and not performance.

Don't you think that Cummins, International and all the other diesel engine manufacturers would be using such technology it that worked? There was a big thing several years ago about water injection and the propane. All the talked died out and I never heard any success stories.
I do know I would not want to experiment with my multi-thousands of dollar engine of something I heard might work on the internet.

I went another route with a Banks system. I plan to help improve it a little more when I need a new exhaust and that will be to increase the air flow in and out to larger size piping and filter. I have used acetone in the fuel and am happy with the results in all my vehicles. I am sure you might get some improvement but the cost of methanol to results ratio would be my concern.

coming from a diesel truck background, it's been done many times and as stated, the mfg's tune to the level of 'get it good until out of warranty' then it's their issue

have tuned every car/truck/motorcycle, etc. I've had the last 30 years...
some within 5k miles off the showroom floor (except for my newest - still breaking it in first)
as long as not taken to the extreme and driven in full race mode all day every day, it's perfectly safe...

FYI, before I do methanol though, I'd investigate air intake and exhaust as any engine is just an air pump at the base level - so better flow in and out will help...

then I'd look at tuning - MANY success stories...
While banks has been around a while, there are better solutions elsewhere.
IMHO and others - banks has a MUCH better marketing dept than engineering dept
there's more to be had for less money out there !

make SURE you read up on the ratios... some wont use anything but water in the fear that too much methanol WILL create problems...

but, tuning for better power with the same or better mpg is a good thing !

do a google search for some of the deezle forums to research the results...

Who does the reviews - writers needing to fill some column inches, or owners needing to justify their spending.

Better to see if you can find any peer-reviewed scientific results and see what they say.

Also have a look at Fuel saving - a professional engineer's view and see what Tony has to say on the subject.

My view is that if these methods were actually cost effective every engine manufacturer in the world would be fitting them as an easy way to meet performance and emission requirements. Even if one manufacturer used them it would be a sign that there might be something in it.

bottom line on performance increasing systems, if they are legit, they will have dyno charts showing base line numbers and then with the system in use. as to the water and methanol there hase been dyno tests. one of the performance books autozone, pepboys, etc. carried was performance with economy(was by the same publisher that had how to rebuild small block chevys, how to hot rod small block chevys, they have books on fords chevys chryslers). it had water, water and methanol. tests with dyno runs. (it's been awhile sence i'v read it, but it's a [lace to look.) this book dealt with gas engines. good luck and let us know things work out.

I'm a new member interested in an old subject. Did you ever try the injection? If so what was your opinion on the mod? Like you I have checked out the truck injection kits all seem to have great reviews. At this point can not a lot of input on motor homes.

That would certainly be my question...these stock engines crank out plenty of torque and HP for what I need.

Then the mods are not for you. Why even waste your time reading and replying if you already are happy with what you have?

I would rather have a propane injection system than water. FAQ for Diesel Performance Products Propane Injection Systems, Gas and Diesel Engines
