Re: Water vs Methanol : Ultimate Tuning
Looking at the diagram it seems that this may work with a TV Supercharger. Would this make sense for a SC as well? It is not super high boost, peaking at just 10psi on a stock NA motor.
I am running Aquamist jets now and wonder if I can improve atomization. Will running a greater number of jets to achieve the same flow rate improve the atomization? In other words, if I switch from the current 1.2mm and 0.4mm jets to four jets (say two 0.5mm and two 0.4mm) improve atomization by a significant degree? I have some real-estate to work with on the intake tract and can pout four jets, while spacing them apart and keeping them in front of the throttle body. |

Re: Water vs Methanol : Ultimate Tuning
there is a hole in the air filter indeed. the spray is injected right through this hole.
For the tank you mount a check valve in the pressure supply line. Once the container is pressurised, it stays pressurised. 20l or about 5 gallons of compressed are generated by your turbocharger within some 200 Milliseconds for a 300HP air flow. After that you only need to replenish the air replacing the fluid. One example found here http://www.sprayernozzle.com.tw/down.../CTGAZ18BR.pdf sprays 500ml/min (30l/h) using 60l of air per minute or 1l per second at 0.7 bar. At 300Hp your car needs 250l of air per second! The loss is insignificant. The same is valid to fill the container. Hydraulic nozzles are spray nozzles driven by high fluid pressure. It is what most of us are using. Working with not too big pipes (for 300HP, 50mm is still OK), not too bog of a IC and a blow off valve, lag due to a intercooler should be minimal on full chat. I see the simplicity of your approach and plumbing a IC is a lot of work. I also tried just WM injection, but had worse results compared to both CC and water injection. |

I have dual jets now but it is just one very large (1.0 or 1.2) one with one very small one (0.4-B). I also have them mounted at 2 o'clock and 10 o'clock in the same silicon coupler. I was thinking to spread them out and maybe put one in the end of the inverted cone air filter that I have. It would point the nozzle right down the intake tract. |

Re: Water vs Methanol : Ultimate Tuning
Here is an interesting thesis regarding Ethanol and Water injection at different water mixtures providing detailed information.
Thanks to Rotrex for sharing and to Baine Breaux for actually doing it. Full Thesis here : http://etd.lsu.edu/docs/available/et...Thesis2012.pdf I took the time to read it carefully and took notes from it. I am attaching the notes phrased from the thesis itself into a pdf. I am also attaching graphs should anyone make use of them. Last edited by parmas; 23-04-2016 at 06:18 AM. |

Re: Water vs Methanol : Ultimate Tuning
Here another Thesis directly related to internal combustion N/A engine and water injection.
Thanks to Gurveer Jatana for his research. https://espace.cdu.edu.au/eserv/cdu:...3_Jatana_G.pdf Attaching graphs and pictures that attracted me. |
