urd 7th injector question?

I have a vortec ProCharger stage 6
on my V6 4.0 1gr Fe motor on a Tacoma..
I'm new in this field so I'm about to ask a very stupid dumb question so hook me up with all the answers I like constructive criticism and positive criticism but I could use a little help hook me up with some knowledge if you may..

, so I'm thinking of getting the 7th injector from urd and instead of using fuel I have a bottle of pure oxygen that I'm not using could it be possible and or would it be safe to use pure oxygen for the 7th injector on my air intake?
it will obviously be controlled with acceleration controller.
wondering if this is safe or if this is something potentially a good idea to add horsepower while using 91 + octane fuel.
if I missing anything please ask me questions cuz I would like to have a discussion whether this is safe or a good idea thank you

 

I'll start by disclaiming that I am not an expert on boosted 1GRs, but I do work in engine development and know a bit about combustion science so I'll chime in with what I can. I will also state that there are many, many reasons why I would not recommend O2 injection but Ill just go with the simplest reason of why this wont work like you think it would.

The purpose URD 7th injector as I understand it, is to add extra fuel to the intake air to prevent the engine from going lean at high speed or high boost situations. The reason the engine would lean out in those scenarios is that your fuel injectors cant deliver enough fuel for the amount of air in the combustion chamber. Increasing the O2 concentration in your intake air through oxygen injection would create an even more lean fuel mixture, which will not result in more power. Basically, to gain any advantage of oxygen injection I think you would also need higher flowing injectors.

 

well, injecting pure oxygen into an intake was tried a long time ago by the germans in WWII as a means to improve performance in fighter planes. from what i’ve heard, they burned up a lot of pistons, valves, and heads. it seems things we’re getting too hot.

however, at one point an engineer thought to try mixing some nitrogen with the oxygen, and after some testing they decided on a mixture of 2 parts nitrogen to 1 part oxygen, or N20, better known now days as nitros oxide...

 

Pure oxygen is generally a bad idea. When you increase the percentage of oxygen, strange thing happen. For example Velcro doesn't really burn but expose it to oxygen and it'll burn through metal. This is what lead to the challenger disaster in 1986 (picture below).

Even nitrous is only 33% oxygen. The oxygen doesn't split from the molicule until around 700 deg which I think helps prevent detonation.

20 years ago I tried connecting oxygen to an engine. Even at very low flow rates all I could ever achieve was engine knock.

Yup. Need pictures.

Also, what are you using for tuning?

Is the fuel pump upgraded?

Are the injectors upgraded?

 

Pure o2 would make the engine so lean it would burn valves

 

Methanol injection was commonly used on DSMs back in the day. Probably a better solution.

 

@Torspd asked the important questions above. We need to answer these.

I have spent some time doing a thought experiment about pure oxygen sidestream. Short story long, it led me to conclude than there were many other ways to get a similar effect for the same (or less) money.

However, if you're hard-on to install it, theoretically the 7th injector would work provided the pressure that the injector sees is regulated, but at the same time if you call URD and tell them you want to use it for oxygen sidestream, they'd probably recommend you don't, while using a few expletives and names I shouldn't say here.

If you tuned your engine management very, very carefully, you could make it work. I won't stand up and guarantee good gains over N2O though, or even water/meth injection.

 

Do you have any sources of anyone successfully doing this? I'm very skeptical that it'll work but I would love to see it work.

 

I found a study done on increasing the oxygen of a single cylinder diesel engine. Obviously not the same but it does highlight some aspects like decreasing combustion duration as the percentage of oxygen increases.

One more thing is the quantity. At 5000rpms, (no forced induction) the 4L consumes about 8000L/min of air. To increase the oxygen from 21% to 26%, you'll need about 400L/min of oxygen. An E cylinder which are the types you see old people wheeling around would last about 100 seconds at this flow rate.

 

Again I have to ask why? It’s a truck. You already have the v6. It’s already got a supercharger. Now you want to add more hp? Reality is if you want speed that much you bought the wrong type of vehicle. Sell the Tacoma and get a muscle car. You will get enough for the truck to afford a nice mustang or corvette.

 

okay cool you guys are the best thank you so very much for the knowledge and expertise information that's exactly what I needed to know I had a small and that's exactly what would happen but I just had to ask because I wasn't too sure or had no knowledge or experience in that field but what I've just learned and just read is enough for me to stay away from using oxygen injection so thank you again everyone.
you guys are very smart and very knowledgeable thank you

 

however I am upgrading my fuel injectors and my spark plug ignition I'm going to be running a hot spark and high-flow injectors from urd.

I'm going to be getting the custom cams and also the internal piston set I was reading up on the forums where a couple of the guys here are doing that same thing and they were able to lay down some good experience and knowledge from their time doing it so it sounds like a good job

 

also I don't want a muscle car or a Corvette I want a nice sports truck I love the way trucks look I like trucks I want a nice racing sport truck..
by the time I'm done finishing my truck with all these so-called stupid mods and everything it might not even look like a Tacoma anymore but that doesn't matter I just want something sick as fuck and I wanted to be different..

you guys will get what you want here soon once I'm getting to build close to done you will have your pictures you will have your entertainment I will even post a video

 

I do have to ask a question I've been trying to figure out how to post videos and post pictures and I can't get it figure it out can someone help me how to post pictures on this website

 

How are you liking the Vortec ProCharger Stage 6? Is there are reason why you didn’t opt for stage 8? It didn’t seem like that much more money for the stage 8 kit. Got any pics of your engine bay? I’m curious how it looks when installed.

 

I didn't realize there was a stage eight and I type the wrong thing there was a typo it is a vortec blue V-5
pulley driven ProCharger

 

I also have that NST 3 piece pulley kit
fully custom.. modified centered intake manifold, port and polished and ported valves black nitride oversized valves with performance spring kit and titanium washer's

everything is blacked out.
I do my own anodized parts.
you can make your own bath by using cloth dye and a vehicle battery charger.
it looks fucking badass
I have true dual exhaust with air injection manifolds.
I also have a exhaust cut off with 2 legal exhaust and my caught offs go to a very short racing pipe that bypasses catalyst and muffler.
at the push of a button

I removed as much metal as I could from the vehicle and the frame itself to do a pretty decent weight reduction.
everything is fiberglass with custom carbon fiber with a chop top roll cage with a custom fastback with a hideaway spoiler,
wide body Axel's With custom flares,
built-in sunroof
everything's been relocated battery computer accessories are all in the back.
I have a black relocated gas tank that's in the bed to make room for my dual exhaust
a full size belly plate for so-called aerodynamics.. lel.
I also have a tundra front subframe swap conversion so I'm using tundra OEM front arm suspension without using aftermarket parts so I can keep my lowered front..
my rear has Austin Martin IRS Axl with disc brakes
possibly doing a rear steering kit for low speeds but not sure yet I'll let you know soon..
there's quite a bit more that I'm leaving out but I also have a tune from Orange virus but probably doing something a little bit more advanced and more serious when I push more power I'm just doing a very simple tune at the moment.
I almost forgot that I have a headlight and brake light swap from different vehicles that I'm not going to say which from cuz I'm going to have you guys guess..
it's looking pretty scary super super spooky, ha!
as you can tell this is going to come out very different and it's what I'm going for trying to build something that nobody else has done something that's completely different from the ordinary I was inspired when I saw those TRD tundras / Tacoma builds that are all slammed and raced out

I wanted to do a V8 motor swap but I figured to stay with the stock motor and just work on that.
if I need more power in the future I am eligible since I have the tundra front subframe already installed I could just throw a big V8 in there but I'll have to tune up the suspension and the transmission and I'll probably have to fabricate the axle again to work with the Austin Martin IRS.

I'm hoping she's going to be very very fast.
the ratio on the Austin Martin axle is 3 point 31 something like that meant for racing so she's going to move very differently from the norm/ it's from a v12 vanquish that can hold up to 650 horsepower stock so she will hold up just fine
liking my other post I have parts from 20 different vehicles and I'm going to make some crazy Frankenstein build to make one interesting truck that's pretty much not going to be a truck anymore but it's going to be what I want.
I'm still deciding on what kind of interior I'm going for I'm going to go all blacked out everything all blacked out the interior is going to have a little bit of gray inside so I haven't gotten my seats yet but that's something I'm not worried about yet.

sorry about the long novel.
last question do you think I should put my steering wheel and seat in the middle and have a super sick wrap around dash.
I've looked into it a little bit and it might be more work than I'm willing to do since I've got all this in the works but still thinking about it going to have two seats in the back.
once I figure out how to post pictures I'm going to put up a few pics of all the parts and products I'm using I took a bunch before I started working on it so I have all the parts all laid out in a nice picture so you guys can see what I'm working with

 

I still need to figure out how to post a picture if anybody can help
