This video is about one of my favourite sounding engine: the Alfa Romeo 2.5 L V6. This engine is quite famous for having powered the insane Alfa Romeo 155 V6 Ti DTM/ITC. The V6 was able to produce 480 hp in its last version at 11900 rpm (!!!) and it was able to reach a top speed of 300 km/h.
In this video you can see four 155 V6 Ti (two 1994 Alfa 155 DTM and two 1996 Alfa 155 ITC) warming up their engine with some scenes focused on the beautiful work of the direct fuel injectors into the individual throttle bodies.

THANKS FOR WATCHING AND SUBSCRIBE!! - ยานยนต์และพาหนะ
Honestly think the 155 might be the best looking sedan ever. Especially compared to anything that came out of the 90's.
Mi vengono i brividi ogni volta che sento questa macchina...
My No1 car, love seeing this thankyou :) :)
+Spencer Spence You're welcome!
A symbol for Italian engine, Great video Bozzy, thanks for Sharing!
What a christmas gift! I love the klasse 1 DTM / ITC cars.
Awesome upload thanks for this one! One of the best sounding race engines around.
+jmcnAr Thank you for watching!
just discovered the sound of this engine and I love it
i just love this car
Jezz! Revs almost as a superbike!
Bozzy! Bet that sounds mental even with the carbon intake box on..
Thanks ..happy christmas man
Grazie!!
+Jeffo Jon J Thank you! Happy Christmas to you too!
I want to see those running on the track just sound sooooooo good
Fabulous.
What a beautifull machine.
queste sono il top...
Wow sounds almost liek a crotch rocket! I love a small pistoned engine!!! Love it so much more with ITB's and stand off injectors!!!! DOPE!
155, one of the greatest cars
if that engine with modern injectors, ecu, etc wow such a beast
High Stress Busso! 😻🇮🇹
That's the first tiem I see injectors mounted outside the intake manifolds
+SpotterJacob Formula 1 technology
+SpotterJacob That's called TBI, or Throttle Body Injection - injector is upstream of the throttle body. Or to some, "pissed off snake", because it has a hiss sound on regular, plano, everyday motors. Mainly one injector for all cylinders. It started in the 80s in America. Costs were the major driving factor behind its implementation. Then it switched over Multi-Port Injection, where there is 1 injector per cylinder, with the injector down stream of the throttle body. Now a higher pressure version is out called Direct Injection - fuel directly injection into the combustion chamber. Costs, fuel economy, emissions, government regulations, and customer overall satisfaction drove all these changes. (Sorry for the history lesson. I'm a gear head, and an electrical engineer.)
+johnnymitz thanks for your explanation. (:
+johnnymitz I enjoyed your history lesson :)
+johnnymitz I enjoyed your history lesson :)
This engine is a masterpeace. Best Race Car ever made.
magnificent
LOVE that red one... =D
I LOVE THIS ENGINE IT MAKES ME AGAHAG
This makes the hair stand on my neck. In a good way :-)
Alfa Romeo N°1 !!!!!
I am like the Alfa Romeo, special car racing.
She's so pretty and sings so beautifully I think I have a crush on this car LOL
I saw this car in the flesh when I visited Frankfurt motor show 1995. I think it's Nicola larini on it
At least 3 different exhaust configuration of this car. The well known 4 exhaust (2-2 each side) with pointed upwards tips. The twin pipes on the right side and the 1 pioe on bith sides. Maybe even more exists. :). Anyway, this car was built by the devil with its own hands. Big favourite. Nice vid.
Devil? Nah this the Lord's work right here! 😂
Beast
3:40 nice!!!
+Senna Love that part too ;)
I'll have one of those road legal please, just wanting to spice up the daily commute...
They are warming up the transmission as well
santa madona the best moments of touring cars
Can somebody explain to me how this engine is built? I heared that the block is from prv v6. What is about the compression, bore, stroke, is it twin spark, 8v or 16v, DOHC? I am really interested in the technology wich is used in the cylinder head.
1 dislike? I don't understand...
He think that it was the download button
So this is direct throttle injection. Would it be better if the primary on these motors were secondary, and they turn on at higher rpm so you have more broader power band? Or that would be too rich and be a waste of fuel? I think it wouldn't because it rev all the way up to 10 or 11k.
It sounds almost like a motorcycle!
That's some sweet engine notes ! :)What does 'ITB' stands for in the Title and what does 'ITC' in the description stands for ??
+شاديل اشانالي ITC = International Turing Championship
ITB stands for Individual Throttle Bodies
individual trottle bodies
ind fab design novo
Lancia Delta HF und 155 sind meine Favs und immer ein unicat auf der Strasse,ähnlich wie gut aussehende alte Skylines oder Supras.Ich hab bei Fiat/Lancia/Alfa. Techniker gelernt ;)
Ua auch Puch G und MAN.
Ps; mir fehlt a bissal der Lancia Stratos.
Orgasmic sound!
💛🧡
Porn to my ears, thanks bozzy
+Distortion1971 No problem!
ALFA ROMEO
That's it's only source of fuel?
Mostro
Curious injection system. Like a cross between carbs and injectors. Looks like you'd get petrol spraying everywhere, looks like a fire hazard waiting to happen.
+AndreiTupolev Individual throttle bodies with stand off injectors, quite common in racing. Even if it was to ignite, which i doubt is a problem, the airflow into the engine would simply suck it back in!
This is a very common setup with F1 engines and the like
+AndreiTupolev Theoretically the farther you can get the injector, the better atomization of air/fuel mixture you get. Or something like that.
+ap2pat but better injectors allow better atomization so direct injection can have much better atomization than a system like Tbi. Also the design of the manifolds and heads plays a large role in atomization in carbed, Tbi, and multiport injection
sjpro1 Oh yea Direct Injection is the obvious future no doubt.
MADE IN ITALY!!!!
No in France, this engine is the PRV, sorry.
@@dohcjaubert6816 solo angolazione delle bancate e distanza dei cilindri, ma il motore e costruito da zero dall Alfa Romeo
Shower injectors
Can someone explain what is happening here? Is that literally the fuel being shot in?
+TastyChevelle Those are fuel injectors, if you watch carefully you can see how they pulse in time with the engine.
y tambien suena parecido al venturi 600lm
Cioè non ho capito: ma quelli sono veramente gli iniettori della benzina??????
+adrian Certo, spruzzano sulle valvole a farfalla, nel video però molta benzina va sprecata xchè le valvole sono più chiuse che aperte, ma in gara essendo sempre aperte non si spreca quasi niente. E' una tecnologia che veniva adottata in F1 all'epoca
Franco96 GTA
Interessante. E' strano perchè così da vedere sembrano troppo poco efficenti. Grazie per la risposta :)
+adrian eh sì, anche a me sembravano poco efficienti ma molti esperti di Alfa mi hanno assicurato che per l'epoca era il top, oltre che spettacolare
this car is 4wd?
rwd
drink drink driiiink ieeeeeeeeeeeee !!!!
Isn't 155 using the 3.0?or I'm wrong💆
This is a DTM version so it's a 2.5
Giù le mani 3:14
Who clicked the dislike button it’s a Mercede’s Sunday Fan.
2:56 it's spilling fuel all over. that's a fire hazard
Canavar
Surely that cant be fuel being injected? Seems very inefficient or even dangerous
Is this kind of injection common for race cars? Doesn't look very precise.
+Boni Hollóssy No. I don't think there is much benefit. Maybe cooling effect due to fuel injection before the cylinder?
Because Racecar No idea. What would it cool down? The air going in?
+Boni Hollóssy As far as I know it helps with fuel atomisation. At high revs there may not be enough time for the fuel droplets to atomise into small mist. There is more time if the injectors are farther away from the cylinders.
The Renault V10 F1 engine had the same setup. If they used it then there has to be a benefit over standard fuel injection. These are piezo injectors so maybe it's for higher pressures.
+Boni Hollóssy Motorcycles sometimes has a similar arrangement where the "showerhead" injectors high up in the intake run at very high rpms for better fuel atomisation, while injectors closer to the valves handle lower speed duties.
the videio would be geat if it wasnt the valve leaking

Oh my...how much fuel was wasted on these engines!
+Peter M Do you see fuel going anywhere but in the motor? These stand off injectors are quite common and give a better atomization of air/fuel mixture. It is more wasteful than a street car for sure but not so much because of the stand off injectors.
ap2pat
I do of course, thats why I mentioned it. Fuel condenses on the horns than evaporates. Means some fuel gone waste. I shouldn't have point it out, since it's clearly visible on the video.
Evaporates where? It just casually drifts off? The motor is making a constant vacuum....
ap2pat
Ok then. Have a nice christmas!
+Peter M I think its good to also realise that a race engine is at most times in full throttle with the butterfly's opened or partially opened and not like this near idle
