Stand off injectors2

[MrSuperviv]

number 3 is burning lean

[Konigstiger222]

funny to see how the fuel meter in cars go's so sad so quick when u see the fuel jus pissing into the engine lol

[89Notch50]

Doesn't make sense to me. You practically have electric carburetors. What is the purpose of having them so far away?

[Hezath]

@89Notch50 The purpose of having them so far away is that their discharge spray is exposed to more turbulence and just a larger area of the intake charge at once, so the fuel mixes in better and it's marginally better from them being further away from the valve as well, but the main advantage that I see is that the inherent duty cycle problem that comes from a typical injector is reduced. So you get the correct mixtures (basically) but the timing of the introduction isn't up the shit.

[Hezath]

@Hezath Why it's exposed though, is lost on me. I think it should have a box enclosing it all, even if it's see-through or something, then at least you can run an air filter and have some flame-resistance in your engine bay in the case of a backfire out the intake.

[kevracing78]

how's part throttle like?

[91cannibal]

this is badass and want to get ITB's with Stand off injectors but isnt this kinda dangerous? i mean you got open gas there. what if theres a spark? KABOOM!!

[LeCourvoisier]

sacrament que c dur sul gaz mon homme !

[Peckerwood702]

daaaaaaaaamn son

[paulbreor]

that cant be a daily driver

[UmakeMeSYK]

Nice itbs i gues u dont have to clean them as much as those losers who have it injected directly inside the individual throttle body hahahaha nice invention anyways cool :D im guessing u can also tap a nos bottle into those lines? or is that a little to hero ish?

[JuanPapaNicolao]

Holy shit that looks cool as hell im no expert but why not make those intakes variable

[Behigh2000]

the first injector blows more fuel than the other 3 together

[cortlander]

bmw e30 m3 ???

[preludefan]

thats awesome, id like to do the same with my next na build, using a megasquirt ecu- how safe is this setup for road use?

[4lewis20]

Wtf Is THAT !????

[5ive10]

@4lewis20 exactly my thought!! i'm guessing there's the normal fuel delivery underneath the stacks? but look at all that fuel from outside - wow

[emptyomen]

it gets a better air/fuel mixture for combustion....but its really only for cars that are going to be full throttle all the time because with out the suction from the intake youre gunna get a TON of gasoline mist in the bay wich is not a good thing, for obvious reasons.

[sirlonghair]

it's a waterfall center piece for a wedding table at My brothers wedding

[Red97Avenger]

nice secondary injection setup with itbs ! very expensive !!!

[Shazee083]

how you do with a carbs what they put in F1 cars

[Tnesjed]

ok its cool n all but what about it being open to dirt? i mean is there some kinda cover? and id be worried about a fire with open fuel like that or did i miss something

[ice788]

haha yeah, there's a cover for it, it's just showing you how much fuel it sucks in. Like i'm not 100% sure about this, but i just know that wouldn't work so well moving at like 140mph.

[mrchampagne77]

i never new such a thing was out there. whats the point of having the injectors on the out side? besides it looks cool.

[raceguy514]

im not sure for the use but its not all that new its pretty old surprisingly

[Maraud3r43]

its like a new technology carb

[Whipit8rapture]

Well i expect it would give a better chance for the fuel to atomise with the air.

[Rich606]

Bingo. At higher revs the inlet valve is obviously opening and closing very quickly; if the injector is right up close to the inlet port then the fuel has less distance and therefore time to atomise properly. Putting it further away gives better atomisation and combustion at high revs. So the best set-ups have two sets of injectors, one near the port for normal engine speeds and one like this for high speed. Otherwise if you have them too far away fuel can drop out of suspension at low speeds

[Rich606]

The other big advantage is that they look and sound the shit ;-)

[Whipit8rapture]

Now that sounds complicated yet in genius! Will have to investigate further.

[rsnupt82]

better fuel atomization, mixes better with air, more combustion, more power

[jnewbon00]

it allows for short trumpets (high revs) and maintains fuel atomisation at a preset distance from port

[formula88]

I guess it gives the fuel more time to mix with the air. But I'm sure he did it because "it looks cool".......

[mytmousemalibu]

Cool S14 in an E30 BMW

[X291J]

where's the s14?

[mytmousemalibu]

Is this not a 2.3L 4cyl Installed in an E30 model BMW M3? If so, the factory engine designation is an S14. It sure looks like it and judging by what appears to be an E30 strut tower, coolant resivior and Bosch altinator! The non-M3 had a 1.8L M10 4cyl engine in the E30 chassis. But what looks like a short flat black valve cover with chromed acorn nuts looks all S14.

[highdeserthater]

@mytmousemalibu the intake side of the KA24DE is on the other side of the head.

[slydar86]

i dont know about a billion to one. backfires are pretty common, especially on tuned cars with stand alone programable ecus. lots of cars out there with very average tunes. i wouldnt run it on a road car without an airbox.

[nitrousboy0311]

NUMBER 3 IS FUCKED!

[pballer2005]

its just the lighting

[quiqueotero07]

asi injectan los F1 :D

[awddorifto]

Its actually very safe. This is the same type of top-feed injectors as F1 and Indycar uses. The risk for intake backfire is almost a billion to one. At the time the intake valves are open, there is no explosion. Its not like an exhaust back fire.

[chapmanmerchant]

#3 is lean

[Bobbess2]

good luck if u have and intake backfire ur fucked

[X291J]

wheres the nitrous?

[pballer2005]

don't need nitrous for an intake backfire

[565Customz]

@Bobbess2 not really

[turbofanman1]

@Bobbess2 yeah wouldnt the combustion exit the throttle body and touch the injector itself? if that happened? like your whole assembly would be torched lol...im a jet mechanic i dont know much about individual throttle bodys or mini carbs as some call them...but as far as im concerned those injectors are totally exposed and looks like the conespray is hitting the edges misting the whole intake side down

[NotYour94Ranger]

@turbofanman1 Even if there was a backfire, the engine induction would suffocate it, kinda like when a jet burps. Too much air volume for a flame front to be maintained.

[zeroswings2]

@Bobbess2 that's with a carburetor... I don't think injectors are that dangerous in that regard. still, an engine fire could happen but I'd have to imagine it'd have to overcome the pressure of the injectors to be anything more than a momentary flame.

[rulecar961]

that doesnt seem like it would be very safe

[viktord1]

damn look at all that fuel man. i bet this thing drinks gas like hell

[Turbojonny5]

I think i have a "hard-on" :P

[TaLoCc]

wtf thatz what bismoto use on his 9 sec insight....sweet

[bikerdude96]

squirt and the fuel tank is gone

[valleyfever]

I have a 2003 Honda CBR600RR. It employs this setup using two injectors per cylinder. 1 low in the throttle body and 1 way above it shooting into it like this. The secondary injectors only come on when throttle angle is 45 degrees+ and engine RPM is above 5500. Honda calls it DSFI (Dual Stage Fuel Injection) Apparently it is F1 technology.. Nice video!

[GazBoffin]

Yeah in laymans terms its called sequential injection, the purpose being (in really high performance setups) that you can retard the timing of the first injector pulse to fire just before the intake valve/s open up, causing the first burst of fuel to vapourise due to the heat, this creates a much more desirable AFR and thus, the second pulse follows, fucking hard to set up from a management point of view, but there are stand alone ems units that cater to that sort of setup.

[marianoaldogaston]

secuential injection is when the injectors open in order and not simultanisly

[jfv65]

BMW touringcar (2002tii) racecars already used similar technology in the early 70's , not with EFi but with MFi: kugelfisher mechanical fuel injection.

They made well over 200hp/litre even back then.

[FuckinShovel]

My e-wang is larger than your e-wang.

cool injector setup btw.

[erinlouise222]

thats a bit insane?

to bad if it decided to back fire

[chiniita1234]

this setup has the same disadvantage as the carb. the traveling distance.. the fuel codensation on the ports ..the inconcestancy of fuel/air mixture so on and so fort.. nice try though

[chiniita1234]

i get wat ur trying to do and i respect that. but the people who made FSI took years of research and development to make it how it is today. im sure they thought about this over-throttle injection ...but ummm arnt u wondering that if theres some fuel condensation on the throttle blades ? would it make a drip effect ? wouldnt that be a gas eater as it is? ...

[sbrdal]

WOW!

[pocock24]

Lol and all the fuels gone

[Micrarwd]

Hi just like to say nice set up you got there, good to innovate rather than imitate (dunno if i spelt that right lol). Would the armchair engineers please stop slaggin these videos off and anyone who actually works with faults on the engine management side of things Knows not to bragg and not to try and diagnose the fault until he/she has seen the fault first hand.

[awddorifto]

Its the fact that these top-feed injectors can atomize the fuel 40% more than a standard injection. They make more power from the same amount of fuel. They are harder to tune, but will maximize the efficiency of the fuel coming in to the runners. And this is better than FSI ...on a performance engine. If FSI was the best for performance, formula 1 would use it...but they dont...they use top-feed injection...look at the video called... Renault F1 Engine

[X291J]

you people are silly

[nsfu19]

can you see that cylinder 3&4 get alot less fuel than cylinder 2&3?

[humantestdummy]

i think it has alittle to do with lighting

[jhaze918]

@X291J its youtube lol

[navdrum001]

man, i dont understand how this is a disirable set up!!? i mean there is alot of chance that the fuel will not make it into the trumpets, also when it rains u could get water in the cylinders (not good) i'm sure i will get a good mix tho, but this surely cant be better than direct injection i.e FSI engines

[killthemall1986]

its the lighting that makes it seem like they arnt injecting the same ammount. what car and motor is in that?

[kimchiR6]

looks like the 1st two are injecting more than the last 2 two?...

[signalxone]

haha damn thats sick. nice to see that kind of setup in action.. what kind of motor/car is this?
