max water/meth vs fuel ratio you've been spraying to your engine ?
Hello all,
I've been wondering what is the max water/meth ratio you guys have been able to spray before it starts to loose power The reason i'm wondering this is cause I accidentaly sprayed much more watermeth (50:50) than I though it was set up for and has been able to gain better timing. So I'm actualy spraying 31% of 50:50 water/meth mix and it looks I have room for more. what would be downside of spraying even more ? Could I spray as much as I want until I reach the point it missfire ? for reference : I use ATM an HFS-3 with a 1mm jet . Engine is 1348cc Turbo with 360cc fuel injector Last edited by zakshaker; 24-10-2011 at 06:40 AM. |

It would be interesting how much more watermeth you can add before it blows out the spark.

My own design CDI/Coil on plug system though. On inductive much less than that.

That's a very interesting subject indeed.
I went up to 80% WM50 (standard toyota distributor with NGK iridium grade 8 plugs) without having any missfire. |

There is a diesel Navarra YD25 now running 22 gph 1387.98cc/m. No progressive control, just on/off boost switch
You can check out his math (link to another water meth forum) http://www.alcohol-injection.com/for...html#post17554 http://www.alcohol-injection.com/for...html#post17559 http://www.alcohol-injection.com/for...di-4-3254.html I am using 2 gph or 126 cc/m in a 650cc engine. Can't find anything about my injector size though, so I can't show the math or percentage. Last edited by Dust; 26-10-2011 at 08:24 AM. |

Re: max water/meth ratio you've been spraying to your engine ?
the reason why I was spraying 80% by mistake is cause I accidentaly had the unit working as single stage while I though it was progressive. yes I did a fuel map and changed ignition timing. From what I have been dataloging. the system performed at its best when it was injecting 60% WM50. so this is my next plan
I will try to install 3 jets now 1 pre turbo (0.4mm) 1 after IC (1mm) 1 before throttle (0.6mm) I have posted regarding preturbo jet location : http://www.aquamist.co.uk/vbulletin/...?t=251&page=42 |

Re: max water/meth ratio you've been spraying to your engine ?

I was trying to see the differen from the logged data with and without water. From there, I should be able to see how mch ignition gain and how lean you can run with water injection.
