Inside a V8 Engine at Idle Speed

[ITRIEDEL]

Throw a penny in the cylinder...

[midgetmayo]

Very cool video. LOVE it!

[LookItsRiceCake]

Sounds like a steam engine.

[WARFOX101]

Stick your hand in there.

[guily6669]

Damn the pistons already look nasty at 800 rpm...

[bigdog8517]

Awesome video.

[pacerman265]

It's alive.....

[NZDC69]

That's an Oldsmobile engine right? Judging from just the rocker arm bridges and the water pump it looks like it.

[BigMaxTube]

@NZDC69 Its a GM engine from way back in 1974. Sold here in Australia under the "Holden" brand, I'm not familiar with Oldsmobile, but if Oldmobile is related to GM, then there could be a link. BTW, Holden also used Chev 350 engines back then around that time too. Thanks for looking and commenting.

[AKhellbindeR]

great video

[monaco74]

aaahhhh. I need a cigarette now.

[peanuts2105]

this looks nuts but imagine an F1 engine doing 18,000rpm!!

[fredmarx1917]

Really cool idea. Thanks for the video.

[bluejay148]

sounds almost like an diesel engine when doing that lol



[sammonsrandall]

Cool vid man smart cause I hear the vfd noise so u can modulate the speed

[MrEghatch123]

WOW!!!!!!!!!!!!!!

[1990BayBoy]

Dont forget to set timing! and what about cam break in???

haha but thats neat

[200103511]

OMG this video is bloody awesome!!!!!!

[Chyne20]

I always wonder wut it looked and sound like... I bet my engine be sayin damn muthafucka slow down!!!!

[tbird1028]

chugga chugga choo chhoololl

[Commando303X]

How are you running it with no oil?

[seapeddler]

The old pedestal rockers are likely more reliable than some roller rockers.

[doubleboost]

makes nice music

[tunastrike11]

old red motor man those old stanard rockers are crap.

[gerbilPROJECT]

kewl.

[sertox12345]

its miss 1 2

[Mysticlambo]

i had no idea that cylinders compress and fire that fast at idle... wow. cool video dude!

[TradeMark2003]

very cool video thanks for posting

[aclsalrfp]

There's your problem, half the motor is missing. Cool video.

[chevywhereitsat87]

very very cool :)

[Renesiz]

Oh, would'nt it be awesome if you could start the motor like this, running only on one side?

[TheV8mann]

this is th idle speed¿ 1:50 ,, is very fast, I was think that the idle speed was more slow, like when the video starts..

[traxxasmaxx33]

@TheV8mann 600-800 RPM for an engine at idle is normal.

[chillincruisin]

isnt that amazing how fast its going at just idle speed? i mean imagine whats going on at 5 or 6k rpms.

[4g63jojo]

its kool how even tho there is no combustion occurring u can still hear the V8 sound

[wakwak350]

i love bang a mole

[seelder]

how does it do this wothout the oil going everywhere

[CactusBobsPlace]

201 thumbs up  .

[beefymeef]

HEY! its like whack a mole!!!

[2s7a2m7]

Nice!

[Enemyofreali7y]

That is SO COOL. Amazing..

[21Jimmy86]

Was that piston slap I could hear?

[JSFER2]

Good old pushrod

[guitargod66]

VERY AWESOME

[RacinJasonInTexas]

pretty darn neat.... nice job

[DWOODY12]

wow this video is very cool!!! I;m doing marine diesel machanics course and i'm deff. going to get my teacher to show this to the class A++ on the vid for sure man!

[BigMaxTube]

@DWOODY12 Thanks for the feedback. This is not my usual profession, I did it to learn something new for myself... by all means, use it it in your class as you please. Let me know how it goes. Cheers! Max

[DWOODY12]

@BigMaxTube They loved it, how are you cranking this engine over anyways air compressor or somethijg? lol

[BigMaxTube]

@DWOODY12 Very pleased to hear that your class enjoyed my vid. It was driven with an electric motor. See my other post of the same engine with no heads @1000RPM. You can see the electric drive motor there. Cheers!

[xMoNzTa]

i am only in tenth grade and i basically know alot about engines. i hope to do a science project but i dont think it would be appropaite to use gas in the combustion and spark plugs, what else can i use. anyways pretty cool.

[BigMaxTube]

@xMoNzTa I'd recomend getting yourself an old 4 stroke horizontal shaft engine to play with. Find someone to help you that has some experience, pull it apart to see how it works.. the best way to learn is to do! Have fun.

[Bartman1764]

put your penis in it lol

[StreetMagus]

Very nice! Thanks for sharing this and showing this. I've always wondered what it looks like when everything is running.

During what section of the video is the idle? I noticed at the end it was fast, how much rpm was that?

[BigMaxTube]

@StreetMagus the highest speed is only around 800RPM, thats as fast as I could drive it with a 2.2kW electric motor. Cheers mate.

[B744ER]

i know this is probably a stupid question but arent the valves supposed to be where the top of the piston head meets the end of the opened part of the cylinder, well im presuming the cylinder openings is the top of where the piston head would meet the valves and spark plugs?

What are those valve like clicking things then at the top? Stupid question i know but this is an interesting vid nd would like an explanation :P

Cheers ! :)

[B744ER]

@B744ER i think im thinking of a 4 cylinder piston engine, cause the pistons in V engines are in a V shape haha !

[36567brad]

things cammin!

[tinmanDMC]

Coolest video on youtube

[sinisasokolovic]

Sounds cool :)

Like steam locomotive going into redline xD

[raun111]

wow!! always wanted to see one from the inside. thanks !!!

[demariojason]

very cool......still sounds better than a ricer....

[moparmanram1]

cool

[guerillatactix418]

Very very cool.

[SigEpBlue]

Nicely done! A few novice gear-heads think I'm crazy when I tell them the importance of things like accurate ignition timing and valve events. Hopefully, showing them this video will help make my points clear! The speed of everything occurring is simply amazing. Thanks for posting the video.

[loky271]

far out! only 800rpm and that thing looks like it cant physically go much faster! wow just imagine that thing flying at 6000!

[the411is420]

thats pretty cool, i thought the pistons would go down a bit more

[runbusrun]

man! thats so friggn awesome!

[maschinenmeister]

you should have filmed the pistons more accurate

[brety099]

this is really cool

[nykuryu]

i cant believe thats idle speed. imagine 6k or 20k of those indy car engines

[LFiers]

Hi there, I have a 308 V8 and would like to know, what is the optimal idle speed (RPM) that it should at? I have been having issues with my batteries albiet second hand and reconditioned ones that gradually get drained in power within months. This is the third one within a year. I didnt think much of it seeing as I got the batteries cheap but its annoying me now. I think my idle speed is too low at roughly 400-600. Is this sufficient enought o charge the alternator? Thank you.

[BigMaxTube]

@LFiers Yeah, maybe the alternator output would be low, and I don't think the oil pressure would be too good at only 400RPM

[slinky460]

Wow. Thanks.

[imautuber444]

thats amazing !!!

[MrBenCleaver]

wow you can really hear how the v8 gets it sound! especially on the r/h bank with the head on. Great video man!

[ruigatinho]

amazing...thanks for the upload

[southernclassik]

Just imagine how fast the crankshaft is moving.

[DeeeJayThrash]

Yay power Stroke every 45 degrees

[leckmich0815a]

Can't believe that fuel burns at 8,000 rpm when this shows around 800? It seems the fuel/air mixture burns in microseconds *wondering*

[arcanacelestia]

Many years ago I worked as a Steam Engine Driver (Fireman) on Rhodesia Railways, and I am astonished to hear how the engine in this video sounds EXACTLY like a Steam Engine. Wow!

[nafism6969]

damn. one loose screw and ur gone!

[AJGohard]

MUSIC TO MY EARS

[bigsonarn]

faster!

[Rawr454]

800? By God, Imagine 8000!

[moore96impala]

Oh i loved it i always wanted to see how a engine rolls with everything off of it!!! Thanks for the video man.

[marcusarelius23]

Excellent demonstration, thanks man.

[lindmark1234]

this is cool how a motor works!

[GhostXoP]

actual rpm? those pistons are actually going at idle speed of a car? at the beginning how many rpm is that?

[justlikejebus]

253 or 308?

[BigMaxTube]

It's a 253. The 308s have held their value well, and as a 'just for fun project', I could only afford a 253. Parts are all cheap and still easy to get. The 308's are apparently much better performers, but that didn't concern me for this project. Thanks for commenting.

[onboc302]

@BigMaxTube very cool

[Znitso]

I was sort of waiting for the engine to fire up there at one point (kidding) by the high revs, i would have fell off my chair xD

Awesome video, thanks for making it.

[mffp1]

40 psi oil pressure ! all right , run !

[cenochs]

Cool vid!

[xhogansherox]

I can't even imagine a f1 engine, cause they are only aloud to run 18,000 rpm. They used to turn more rpm, but they changed the rules.

[TravvyG]

Sounds like a Steam train lol.

[rallyausofficial]

sounds like ol gordons just pulled out of the station haha

[TravvyG]

lol

[veryslyfox]

how much did you fvck up this engine by running it without oil?

[SkidpadPro]

@veryslyfox Good oil, and no load on the engine.

[dirtrider383]

@veryslyfox thers oil what do u think that gauge is

[bww1972]

It's a good old Aussie V8 4.2 or 5.0 litre.

[scottb953]

Looks like an Oldsmobile engine

[SuckeroftheYear]

very interesting....

[shdwsclan2]

The engine is ancient.....or american....

The distributor is outdated, 2 valves per cylinder only, and valvesprings and by the sound of it there is a delay between the firing cycle....even at high rpm....not well engineered..

[Fast355]

This engine design still kicks most of the other engines to the curb in power production. LS7 Corvette for example.. 505 NET HP and 500 ft/lbs of torque, 2 valves per cylinder, pushrods.

[shdwsclan2]

Unfortunately, here, in the 21st century we use 4 valves/per cylinder and DOHC for superior performance.....why do you thing GM needed a bailout.....

[CSMiller00]

you need a bailout

[LX8VD77]

But GM-H doesnt need a bailout, thats who made this engine......

[OverlyExcitedNewJack]

@Fast355 WOW! 505HP all from just 7 (seven) whole liters of displacement? :o

[veryslyfox]

haha yeah, 505 hp from a 7L engine is total shit, like 1950's technology . Good cars make 90-110 hp per liter. American engines suck ass

[kkage2]

the engine is gigantic... i bet the titanic made a lot of power too...

[moparmadness74dodge]

@shdwsclan2

Large displacement motors usually don't need the extra valves, the idea of using more and smaller valves lends itself better to small engines, (2.0L 4-cyl for example) in that they can still get the flow for high RPM but maintain high velocity at low RPM, a large displacement motor can maintain the 'flow' due to the mass of air moving. We also have 3-valve V-8 (see Ford) and the Mopar Hemi, and Chevy LS motors do well with 2 valves. There are reasons for all types of designs.

[LX8VD77]

shdwsclan2, do you see that there is only one head on the motor, of course its going to sound like it has a delay in the firing cycle.

[halofreak1180]

@shdwsclan2 Atleast it aint a shitty foreign engine. I'd prefer any American made or ancient engine over one who's thottle will stick.

[KooKas2oo8]

That's Toyota, that doesn't apply to all cars not from America -.-

[halofreak1180]

@KooKas2oo8 Brother, in my opinion, it does

[kriegdouch]

ha sounds like its running very cool

[RPDXC]

Very cool!

[cheenusrinu001]

wat is this rotating... horzontally at 2:05

[JeepWrangler1999]

its the distributor. the distributor rotates and activates the spark plugs in a specific order for each cylinder. i dont really know how else to say it

[cheenusrinu001]

ok ok ..... ya i got it man..... i never looked an engine like this b4....

[JeepWrangler1999]

sorry if i sounded like a smartass there. i didn't mean to! =D

[cheenusrinu001]

al right

[naxps]

I have a random urge to go over to you house and try to shove a ball park frank into the cylinders while it's running. I dunno why.

[JohnnyGTR34]

Stick your fist in that cylinder at 800 rpm.

OUUUUUCCHHHH

I never imagined it to go that fast, even at idle speed! It's mind blowing how those parts hold up!!

[petrodin]

what are you running it on? some electric motor? nice to notice that V8 rumble is coming also with only air when there is enough rpm's

[SuperTyphoon]

Wow, this is definitely the best inside engine video ever!

[V8Jagnut]

cool

[Hypertenzion]

Sounds great - And funny with those bubbling sounds :D

[BigMaxTube]

Yep, thanks for your comments, those bubbling sounds are caused by air being purged from the lubrication system... and the regular took-took took-took sound is the fuel pump pumping air.

[DrunkOnCapeCod]

What are you talking about , Cylinder Web ? There isn't a valve cover on either side of the engine dumbass.

One side has a cylinder head on it and the other doesn't.

[MavDude]

I hope you're joking. LOL

[Toasty504]

wooo looka them babies go!!! mmmmmm

[nxmoparmatt84]

that doesn't look like 800 rpm

[xqsnake]

best insider ever :D

thx a lot

[zeroangel25]

Sounds funny XD

[FabriEg6]

nice video !!!!!!!

[gizmo98550]

my man thats pretty neat.. i like the "cutaway" look you have on it

[dvddmc]

Great stuff thanks!

[ATeamOps0391]

that's 800 rpm at 1:50?

[ATCOTractor]

how warm does it get just by turning over??

[BigMaxTube]

If run long enough, it gets fairly warm (too hot to touch for more than a few seconds) It requires around 3hp to get up to idle speed, so this is around 2.2kW being converted to heat.

Thanks for your comment.

[ATCOTractor]

Plus the air is being compresssed so that gets hot.

[BigMaxTube]

Actually, no air is compressed as there are no sparkplugs in the head. So, I suggest that the heat is all due to 2.2kW of heat due to friction. The Nature of the Beast.

[ATCOTractor]

oh right and on the otherside theres no head =]

[F4cPhantomII]

AWSOME !! I love engines !!

[HarrisPerformance]

thats a really good vid, thanks for posting it!

[RockinGuy1994]

That was so cool! How was you spining the motor?

[jtster]

awesome vid thanks for posting

very brave standing infront of the pistons going at that speed imagine if one had shot off :P

[sagar169]

awesome...thanks for posting

[elixier22]

thats amazing that really is

[DaFuckingFusionPR]

just awesome

[fordsforme1]

that was the coolest fucking thing i have ever seen cool

[JAYB18EG8]

dare you to put your hand in one of those cylinders :P

[AgentJayZ]

That is a really strange project , but fascinating to watch.

Even at such a low engine speed, the pistons seem to move impossibly fast.

How do they get done what they gotta do in such a short time?

Makes me want to rev my 5.7L Chev even harder, just to see if it really can do it!

[1976cheby]

@AgentJayZ Yea lets tear our engine up... u probally dont even know how many cubes a 5.7 liter is.... here i tell ya it a 350 small block chevy wanna keep talkin?

[AgentJayZ]

@1976cheby Wow, you're going back a ways... I'm now stuffing propane into an LQ4 364 running a Comp XFI 269. Doug's longies into an X-piped 3", out thru Edelbrocks. HPTuners lets you set the shift points at 6,000rpm... I wake up everyone.

Those old school small blocks can't rev like an LS!

Cheers!

[itsoundzgood]

@1976cheby Dude your an idiot, everyone knows a 5.7 chevy engine is a 350. Plus who gives a shit, if he wants to blow his engine up then let him.

[sniperv25]

when you see all those moving parts, especially the pistons, you realize how much oil is the lifeblood of your engine.

[shungie101]

at the beginning i was like if it can idle that slow... with only that many pistons and for its size... it must be a world record ahah then it sped up

[ryantonykarter1]

wat mm is those valves and how many horsepower are those rocky arms ??????

[mikeyt368712006]

what the hell are you on about

[Ceasar1030]

It most be like standing in front of 4 subwoofers when you were in front of the pistons :P

[blunts069]

crazy as thankyou verry much you have made my day

[PatrickEthan11]

it sounds like a train

[s7jstep1]

thats crazy. and thats only at idle speed. imagine 5000 rpm. awesome video

[aheartattack1]

thats sooo sick!! good job

[thenitro15]

it kinda sounds like a dragster engine loping when they are at idle lol

[thenitro15]

at 1:26 it sounds like its a loping engine

[seek0316]

thats what life is about

[holdengrp3]

It looks like a 308 or 253 cool vid

[jaydnisevil]

1:46 make you appreciate how much stress your engine goes though..

Thats just at just over tick-over (idle) Imagine at 6000rpm.. That ammount of mass flying around inside a little sleeve .. Insane, thanks for that :D

[TEFLONTHADON]

Balance is an amazing thing isn't it xD

[jaydnisevil]

I rekon :D

Imagine if it was just slightly out..

Lol thats partly why I love boxer engines, no need for counterweights :)

The H6 in particular :D

[TEFLONTHADON]

Yup xD those and inline engines. Even those if any balance gets out pieces will start flying.

[tordenkylling100]

1:59

Do not put your fingers in the cylinder! :D

[digitalrailroader]

actually, around 700-800 RPM is just Right for Idle Speed!

[twowheeljunkie101]

cool video, almost sounds like its running for a minute haha
