Turbine housing, divided or single?

[Grant Monkhouse]

This is a complete and utter rubbish :Hammer

I inject as much water as the WW2 aero planes did and I have no water leaking out of every orifice :chat

It is an easy science, people just need to get into it, there is a whole forum dedicated to it with some of the smartest minds in this field contributing and posting about it //www.aquamist.com

Honestly Peter it was in one of the pieces if Information through your website, unless I a remembering it wrong? I will check when I have my laptop. To show you.

I will apologise now though if I am wrong.

[Grant Monkhouse]

so rice how much money do we need to give you. for the kit the map and the knowledge?

Email him direct, I think it is a fair price for what you are receiving.

You may have looked at one paragraph where a test was continued on to see just how much water could be administered into an engine :2Confused 150% of the fuel flow has been tested. Some people I know did a thesis on WI on a nautral engine and feed through this amount in their tests too. Long term it can dilute the oil in such massive qty\'s. :Giggle
 
I run anywhere up to 60% at certain loads (over many cars, and almost 2 decades now) and there is never any sign of "water comming out every orifice" or oil contamination.. :evillaugh  These "moderate" ratios are fully proven and acceptable for our applications.:Thumbsup!

[Grant Monkhouse]

Yes that\'s the paragraph I was talking about. Knew I wasn\'t making it up, maybe I should have said it in a different way.

I know it was a test to to see how much they could basically get in there. I know WI on our car systems wouldn\'t do this.

[PGiljevic]

Please excuse me going of tangent but Water Injection just gets me excited :spank

[Grant Monkhouse]

Don\'t worry, I started the topic and like discussion to expand into other things, it\'s good for the learning process

[Turblown]

Water injection does work great, but you need a WELL built system if you are going to run high boost...

[CharlieP]

No one has mentioned  what tips they use!?
I\'m certainly no expert, but chatting to an engine builder, he said that he ran his engine up to 3 bar and didn\'t crack the tips, but the housing, the idea was to keep increasing boost to find the weakest link
Think they were the aviation 2 piece

[suba]

I have never understood WI - though all the knowledge I have is on piston engines, where it is mostly used to stop det in high boost applications - where det can\'t be stopped by retarding the ignition any further.

Mixing methanol and water can increase octane rating of the fuel, but you have to map to it, and in the event of a nozzle failing pop goes the engine....unless you start to run an ECU that can sense the failure and switch to another map...it all starts getting complicated.:Hammer

[PGiljevic]

This "failure" scare campaign pushed by some is just total bullsh7t! :Hammer

FFS it is the most reliable thing on the whole car system (the way I make it) :3gears-lh

I mean if c^nts in 1940 could make aero planes reliable to not fall out of the sky and go pop then you would have to feel pretty hopeless not being able to run a water injection system in 2010 :chat

The simple fact is many more engine go poop running no WI (at far lower power levels) than any do without it she is free and easy horsepower :cool but best thing about it your car WILL run longest of all on WI :Laugh nothing of ANY alternative fuel type can match it :bandit

Water Injection, reduces Peak combustion pressure loads, it increases average pressure BMEP and thus power (it makes more power for less peak stress on the engine), it eliminates detonation, it allows up to 60% power increases without needing to change fuel types, it allows this without needing to increase charge cooling or engine cooling requirements as the water consumed is a total loss coolant (how it was originally discovered in the early 1900\'s)........ it is the best thing ever found in internal combustion engineering, but also the most mis understood and ridiculed by people with no formal qualifications on the subject. For our applications its the NIRVANA of power production, and ironically durability as well.

GET ON IT

lol, someone needs to sig this.

[DR SCHNITZEL]

do you mean a block far from stock?
or an expensive ignition setup

[DR SCHNITZEL]

So at 2.5 bar  up to 60% of fuel volume additional as water.
 

1.6	25%
1.8	30%

 
??
assuming a 10 to 1 afr. accross peak torque and power band ( i know you could tune fuel out but not how much)
 
10 parts air
1 part fuel
.25 (roughly) of a part water
 
at peak torque and power smashed straight into your impeller??
 
thats quite alot of water. I just thought of these calcs in my head. has anyone got a better idea than this which i effectively made up.
