Water Injection

[Todd T]

well, the PROJECT, got put on hold.



my wife delivered me a beautiful baby girl on friday morning. momma and daughter are both fine. she was 10lbs 2oz.



something else i have found out since then, is that to inject post turbo we need at least 150PSI on the pump. this is to keep the system from backfeeding and to give it enough of a spray to fill the intake tube. it has to have a curtain of spray for the air to pass through, to pick it up and deliver it evenly.



I still intend to inject preturbo using the NOS nozzle and a water alky mix. so my 60PSI sureflo pump should sufice.



i just need to put my baby girl down, and go do it. it's funny the love a father feels for a baby girl, it has to be twice as strong as it did for my son. but we wont tell him that.



thanks for the part # Johnboy and Gonzo.

Pump tec 220# psi pump

Here is a photo of the pump I am using. It is a Pumptec 220# psi

I got it through Northern Wholesale it is on there website at $149. 00. CONGRADULATIONS ON THE NEW ADDITION!!!!!! Hope your experience with a daughter is as good as mine was. She is married ond out on her own. We had some very good times together. . Good luck!

That pump looks beefy enough... that's for darn sure!

Hey Gonzo, do you think i should inject post turbo and go with a high pressure setup?



my thinking is that it will atomize better, keep the after cooler from getting saturated and if i decide to go with NOS down the road, i'll have the nozzle where it needs to be already.



Chris PM'ed me and said he had fairer results going post turbo than with it ahead of the turbo. I think it may have been due to, too low of pressure and possibly the nozzle used.



what do you think?



i'm fabing up a new intake tube from the filter to the turbo out of 5" steel tubing right now. i planned on putting a few fittings in it for sensory input and/or water or other somewhat volatile substances



I thought i could put a nozzle in the tube from the aftercooler to the intake horn for water inj.



I can HIDE the system better there too.

Yes I would agree that the after intercooler would work as well. I the high pressure pump is a must in that appliccation. The ideal nozzle placement would be in the center of the pipe, a cone spray pattern and aligned to spray the direction of the air flow. The more atomised the spray the better. I would much rather have a near fog than droplets. The beauty of injecting into the face of the compressor wheel is there is no question on mixture distribution. It will work with less pressure. However in cold conditions you could have condensation problems. Methanol is very easly vaporised but I am not sure of how easly it is condensed back to liquid.

 

[Todd T]

I dont know the point of condensation either. but i have been doing some research into methanol versus ethanol (denatured alcohol) and they are very close to each other in the catagories i am concerned with. for example meth is 107 octane and eth is 108.



the only concern i see is that in ethanol the BTU/lb air stoichiometric mixture is nearly half that of methanol. in lamens terms, when mixed into air, ethanol is half as hot burning per pound of air. but the cooling effect would be the same.



i really dont think this should concern me though. i need the system to cool my intake charge not for more power. and denatured (wood) alky is readily available in hardware stores.



I dont need this system in cold weather either so condensation is not a concern. + how long do you really think condensation would lay around inside the aftercooler anyway. i think once the system was turned back off the condensation would burn off pretty quik.



the NOS part number Smoker was talking about is 15685.



I am really leaning toward post aftercooler for my system. just in case i decide to use NOS later. my next move with the truck is to put an H2E hybrid on it and NOS would help with the lag time. and maybe give me another 150HP too



I found the pump you are using Gonzo, thanks again for that one. its part #52065 on Northern's web site.



now that i have all the parts the weather is too cold to do anything with it right now. oh well it'll make a good springtime project.



now, who knows anything about Hexadecane (CH3) and where i can get some also some Fischer-Tropsch wax

I have NO idea on the chemical differnces of ethanol and methanol. But I do know that Methanol works very well for me. I agree that the potential of a puddle of alky in the intercooler would evaporate very quickly and be burned in the engine. I have flooded my turbo to the point of having alky dripping out of the compressor housing and the engine consumed it dry in just a few seconds. I however have never puddled into the intake manifold that I know of. I know this would be a very bad thing.

 

[Smoker]

So, has anyone put a system together yet? Thought I would bring this back to the top since the first gen. forum is talking about the same thing.

 

[HoleshotHolset]

Once financial things come back to normal, I plan on buying some sort of setup.



I may just opt for the pre-made one..... works great since someone else already spent some $$ doing the research.
