Ah, here we go. Knew I saw it somewhere around here.

Ah, Rice Racing once again. But then again, it's just one guy. But then again, he's been daily driving and circuit racing with 500rwhp on the same block for 5 years. Or something like that...

 

The problem is, the people who have done it before haven't done it right. Check out this thread for more information.

 

Aquamist's nozzles are not up to the task for optimal atomization. You can ask Larry himself about it if you'd like, he's on the WI forum linked to in my last post.

 

some people are running high $$ turbos.... why risk it. inject just after the IC if you can... if not then just before the TB is where lots put it.

 

HEY guys have you looked at turbobuicks.com on alky injection , also turbo mustang, like snow perfomance .com pretty impressive stuff, I have run alky /water/ Klotz for almost 3 yrs , afraid to go over 15 psi with out it, may change to just alky/Klotz in future. RON check out highly modified 420 hpin this same site how I did the nozzle install pics

 

The people interested in pre-turbo injection are likely to consider the compressor wheel as a wear item. I know I typically don't keep the same turbo on my car for very long (mileage-wise). I think it's silly to say that someone will spend the coin for an expensive turbo and not want to maximize the setup at the expense of a small cost increase.

Besides, as I think I mentioned before, the benefits are the greatest for someone who is already running their compressor off the map. In this case, it's usually a small or stock turbo that either will be upgraded soon or is on it's way out. In my case, I'm planning on trying it because I've otherwise reached the max of the turbo.

 

BOY you guys really lit the fire on this thread, anyway I think none of the available systems come close to what is needed like 500-1000 PSI injection presseures, to atomize the additional what ever you want to inject, so as to make it mix better in the chamber to control burn rate at more precise speed, also the injectors should be closer to the chamber , I know ! then you lose the cooling effect in the manifold conduits. but the best of all would be injectors directly into the chamber, but none of us are ready for that. just thinking ahead. RON

 

No, the best water injection system would be a combination of nozzles at various points of the system. Mine would include one nozzle pre-turbo and either another nozzle pre-throttle body or individual port injection nozzles. I actually had an idea for using fuel injectors, but for a water/meth setup, the system and injectors would have to be designed for alcohol use.

 

Idea. What about N2O injection? You need special insulated braided lines about 12$ a foot a nosel that wont frees at -380F and a container such as foam or anything n20 compliant easily found and a -380 aqua water pump found for 120$

N20 wont have the absorption property’s as water but will basically freeze everything so the air would be at least a 0F temp and the aluminum intake would be chilled and I wouldn’t doubt lower fuel temps.

Mercedes has a nice design where they run there fuel lines through the AC unit to cool the fuel.

 

wouldnt you want the water to be injected before the IAT sensor? that way ANY change that the water has on the intake charge is read by the ecu? makes sense to me. . . thats why mine is in the stock position and the injectors are to be in the throttlebody elbow. . . on my FD.

the fuel injectors are a good idea. . . but itd be a little hard to find the correct size for all of those. . . PLUS you have to make them work via some ecu. . . totally custom IMO.

NOS injected into the intake to cool the intake charge down???
You mean just like a regular NOS "dry" set-up?
You got other things to worry about than just cooling the intake charge down!

lol RETed you have a 1 track minde. GO FAST! I was refering to liquid nitrogen.

N02 I think it is I posted it backwords :-D

 

liquid nitrogen (N2). Ah, iceblue, you crack me up.

edit: Oh, and your air wouldn't be 0F. I would be -321F. Your air would also be liquid at that state.

 

There's always LOx

 

i like watching the guys laugh in unison

 

And it's even a 5X better oxidizer than regular air. Though we should probably replace ordinary gasoline with liquid hydrogen for maximum power efficiency.

 

Well I am not sure how fast it will cure the air but I promise it won’t be liquid. Or one of my computers would have been a solid brick last year. The nozzle would vaporize the N02 and the intake would be chilled with the slow steam of the nozzle vaporizing the N02. This is the exact opposite of water and more along the lines of a reveres pelter plate. N02 would also evaporate rapidly causing it not to effect combustion flame.

I could build the system for probably 350$ or so.

SonicRat what is LOx?

 

Then that woiuldn't be liquid nitrogen. And LOx is liquid oxygen.

 

I always thought it was a bit higher than that. But you have a point, LH2 would go quite well.... (Unless you mean CGH2?)

I'd hate to be rear-ended though!

 

^ Sigh. Maybe I will pull out the equations again and how liquid nitrogen actually works, seeing as you do not seem to know.

Lox sounds interesting.

 

Well, I'm just going on there's 5 times as much oxygen in pure oxygen as in air. Haha.

 

ERRRRR CRASH and the rat goes boom!

 

iceblue, I would love to see what kind of equations you're going to use to show me how liquid nitrogen works.

 

It would be long ones. But I have had a good bit of exsperiance using liquid nitrogen.

 

Go ahead.
