HEADER COLLECTOR SCIENCE

[josentexas]

try some try y headers those things are beast

[zanyredonkulous]

i wish when i did my apprenticeship i had a boss like this

[Walshy044]

That was an interesting video, just like your other ones, good job!

[groutaone]

@Walshy044 Thanks for checking it out

[magna59]

Great vid........you missed your vocation. Get the mortar board on & the chalk in the hand & you'll have those on line courses up and running before you can say "....and now for homework......."

[groutaone]

@magna59 Thanks, dang dont remind me of homework, those were not fun days lol

[michaelovitch]

that's a very good experience and really instructive !

thanks !

but (tell me if i'm wrong ) on the engines the extremity of the pipes are closed by the valves.

the strokes are not at the same time and there are counter pressure when the valves close.

the gaz pulse of each stroke is helpful to pull the next but it depends of the length of your pipes and it works good only at a certain rpm.

very good instrucitve and simple example !!!

how do you do the clean transition with your other you : )

[michaelovitch]

@michaelovitch

i've seen a guy doing the same to emty a gas tank

works good.

[groutaone]

@michaelovitch Glad you enjoyed this vid, maybe I have a twin, or maybe not heh heh

[WesternStar4900SA]

One of the coolest videos I've seen, cool stuff!

[groutaone]

@WesternStar4900SA Hey thats good news, glad you enjoyed it.

[pizzaisgood14]

the exaust pipe on just one of those cylinders is larger diameter than the entire exaust system on my car

[groutaone]

@pizzaisgood14 These are 2 1/4, they seem to get the job done though

[vortecroush]

few years back i argued with a guy about how his car needed back pressure to run properly! his argument, why doesn't top fuel dragsters run full exhaust? 100psi boost +90% nitro= no need for back pressure...LOL

[groutaone]

@vortecroush Most competition engines will make max power with open headers however low end power is reduced with that kind of setup. So mufflers are helpful for street engines

[vortecroush]

@groutaone ...it was his daily driver....i just told him it would run really lean without the exhaust. anyway good vid!

[rekjavicxxx]

Really nice simulation vid bro!!! :)

[groutaone]

@rekjavicxxx Thanks for having a look, come back anytime

[TheDieselStop]

That was a really cool class. Thanks for the info,

[groutaone]

@TheDieselStop Best part is no homework after class, thanks for stopping in

[GEARHEADGUY92]

dont forget that there needs to be backpressure

[groutaone]

@GEARHEADGUY92 Would be interesting to simulate a muffler, this simulates an open header compitition engine

[piaceoRS]

Really nice stuff grouta... probabilly i'll work to something with this principle. However... i want your CR.. how can i do???

[groutaone]

@piaceoRS Thanks buddy, interesting stuff huh? I dont think you are the only guy who wants my bike lol

[IHcubcadet]

Wow never would have thought of that. Cool stuff.

[groutaone]

@IHcubcadet I kind of liked to see it happen myself

[seangeron1995]

i didnt get how one of the taped hoses made the water spray up in the main hose?, if i worded that right.

[groutaone]

@seangeron1995 It works on the same principal that makes an airplane fly, when air passes over an object it creates a low pressure and in this case when air at high speed entered the collector via the short hose, water was forced up in the long hose next to it.

[merlyn59]

Thank you my friend for the kind comments. It would be great to meet you in person, see your car / bike run in person and do a little bench racing at some point but I very much respect you privacy and would never impose on you to reveal your schedule.

[merlyn59]

Hey, watch it with the sir stuff, you're making me feel old.. or as we (retired) enlisted types used to say in the military, "Don't call me sir (as in officer), my parents were married." : ) Just kidding...Looking forward to your next vid...really enjoy them, and, your replies (very rare on YouTube!) No need to answer this question but I was a bit curious.... Do you ever run you car at Gimli? I'd really like to see it run in person.

[groutaone]

@merlyn59 I Couldnt help myself, anyone who works on military turbines for 30 years gets a salute from me too. I have run in Gimli but never with this car, however this engine has run there in a 3800 pound (with me) street car, went 10.04 @ 136 pump gas, no bottle, no trans brake, tight converter.

[merlyn59]

Btw...that is one potent motor to go 10.04 in a 3800 lb. car without a bottle! Did you build it yourself?

[groutaone]

@merlyn59 Yes I built it myself with all aftermarket parts, 598 cubic inch

[JTarver420]

very nice demonstration!! Gonna start calling "The Professor" LOL

[groutaone]

@JTarver420 Professor BS, thats me, Thanks for watchin this one

[merlyn59]

Canada's Warren Johnson? He could sure make a Pro Stock fly......

[groutaone]

@joe13694 No problem, it was a fun vid to make

[vipermech]

Just emagine the potential if you added the neutron deflerctor to the end of the collector. Hmm.

[groutaone]

@vipermech Id try one but Iam fresh out lol

[HobbieZones]

Very interesting and informative.

[groutaone]

@HobbieZones Thank you

[ziggassedup]

Good vid bro...I was waiting for the explanation on the order the pipes are situated at the collector...as in the order the cylinders fire...there is another little trick a mate showed me to make MORE power...It involves a small exhaust leak....so to speak.

[groutaone]

@ziggassedup Thanks my friend, yes theres much more to talk about on this subject, may make another vid on this

[buckinjeep258]

Awesome vid, I was thinking about headers and what i could do to mine to pull more power just last week, thanks great vid!

[groutaone]

@buckinjeep258 Glad you enjoyed this vid

[merlyn59]

Very interesting and informative. I've worked with turbine engines on high performance military aircraft for 30 + years and I am very familiar with the characteristics of convergant / divergant ducts and how they affect engine intake / compression / exhaust / thrust but this is the best illustration I've yet seen re: recip. engine exhaust flow characteristics. Next challenge: Any advice on two stroke expansion chamber design and construction? Thanks again,,,great vids.

[groutaone]

@merlyn59 Well thank you very much sir, other than testing two stroke pipes on a dyno Iam not sure how I would test them, but hey who knows whats next, thanks again

[belizetj]

Great vid man!

[groutaone]

@belizetj thanks

[vitolizer]

Derby people would love to see this! Thanks for the vid!

[groutaone]

@vitolizer Ya I kind of thought of those guys when I made this vid, they run 8 stacks and thats it

[Ls3guy]

cool video

[groutaone]

@Ls3guy Thanks

[sbartasek]

I think that's the first time I've heard of the Bernoulli effect. Like everyone else said, wow I had no idea they'd make that much of a difference! Any idea how much of a difference the length of the pipe after the collector makes?

[groutaone]

@sbartasek not sure how much but it all makes a difference

[MrMadkaw400]

yeah no dought i didnt know ...but very cool

[MrMadkaw400]

that is very cool stuff mr wizard.....ha..ha no but fo real thats cool

[groutaone]

@MrMadkaw400 You know I had no idea the collector would work that well, I thought it would help but wow!

[540merlin]

Possibly your best video to date. Fascinating information shown in an easily understood manner. And I like the "Oh, so now you want my help" thrown in - I laughed. Great job.

[groutaone]

@540merlin Hey my big block friend has arrived, well thanks so much for your comment, glad you got a kick out of it

[YamahaBeast41210]

wow, that was interesting! Never new that it helped like that. Loved the science behind this video though. Another Great Video(:

[groutaone]

@YamahaBeast41210 Thanks for checking it out

[groutaone]

@dl650stromer  Thanks , glad you enjoyed it

[yzkx711]

you should compare manifolds to headers too

[RamblinAround]

Great explanation......well done!

[groutaone]

@RamblinAround  Thanks Jeff

[kerobinsonii]

Excellent video ! 

[groutaone]

@kerobinsonii thanks

[edzgarage]

I took a header once on my motorcycle... Ouch! lol

That's pretty good explanation Buddy! Do you tune the collectors for certain engine sizes and power needs?

[groutaone]

@edzgarage Ya I bet that was a fast blister you got that sucks. Yes picking the right size pipe and collector for the application will help power, most will error on the big size

[KristofSX]

woohoo that's awesome, never thought that it works that way ! great vid

[groutaone]

@KristofSX Thanks, I didnt think it would work as well as it did until I saw it happen

[cornholio114]

More videos like this PLEASE

[groutaone]

@cornholio114 I've givin it some thought over the last few weeks and I think I would like to start making more tech vids

[cornholio114]

@groutaone Thankyou!!

[theGHETTOMAN1]

Awesome bro! *thumbs up* Best explination I've heard someone say! ; D LMAO I painted a truck frame with tremclad that way! 2 nail holes in the small paint can lid, short chunk of gasline off an old tank and basicly shoot the air from a blow gun at 90 degrees across the tip of the tube. use smallest tubing possible and I bet you'll freak at how well it works! I know I was shocked..and died laughin.. heehee

[groutaone]

@theGHETTOMAN1 Ha ha thanks man, I can imagine your system working and that would be kinda funny

[ndiboomer]

Nice real-world example of bernoulli's principle!

Wikipedia has a nice page on this.

[gabbermaikel]

nice subject, but now get a test setup for a 4 2 1 system, maybe there is a big difference visible

and nice idea how you made a test setup, it shows nice how the difference is

and you just told all those ricers that the biggest exhaust isn't always the best so lets hope the see this video and remove their fart cannon and get a real exhaust that does give them more power

[groutaone]

@gabbermaikel Ya thats just it, size is not where its at here, speed of the spent gases in just the right size pipe is key

[clawdfrawg]

Hoping for more on the subject aswell as runer lenth.

[groutaone]

@clawdfrawg I'll give it some thought and I may do some more

[yourmom922]

awesome video. great job.

[groutaone]

@yourmom922 thank you

[QuattroStig]

That's a great demo explaining exhaust scavenging.

[groutaone]

@QuattroStig thanks

[WhackTheWax]

I did not know that! Thanks. That was cool.

[groutaone]

@WhackTheWax I really didnt know it would work that well, fun to see it happen

[kortt]

cool, you explained that very well. Nice to know the science behind cool stuff.

[groutaone]

@kortt Thanks for checking this one out

[viirus35]

i smell a good business starting lol

[groutaone]

@viirus35 Nah, I got too much stuff on the go as it is, if I do more it would cut into my youtube time lol

[2LateIWon]

great demo!!!

[groutaone]

@2LateIWon Thanks

[happywombatproducts]

wow that;s pretty sweet, thanks for sharing, this summer you should get a TON of helmet cam rides on the 500 ive watched pretty much all of your videos of that beast haha

[groutaone]

@happywombatproducts Thanks, should be a good helping of 500 vids on the way, along with the buggy and other stuff. Groutaone says you never know whats next

[happywombatproducts]

@groutaone haha i just cant get enough of that monster, it's gorgeous! haha and did you figure out what was wrong with the buggy?

[groutaone]

@happywombatproducts I got a box of upgrade ignition parts today so I hope things are gonna happen now

[happywombatproducts]

@groutaone sweet, cant wait to see that thing rip this summer!

[MyAussieDay]

Interesting Thanks for explaining this.

[groutaone]

@MyAussieDay  Had fun, no problem

[daddytech]

I don't get it then what is the function of the back pressure with the economy of a vehicle then if the collector helps pull the spent gas from the manifold? i thought i had that one down pretty well and this kinda blows a hole in the whole theory of back pressure that i had worked out in my head. (dangerous place BTW lol)

[groutaone]

@daddytech Ya this whole test gets a guy thinking

[daddytech]

@groutaone yeah it does and it's got me thinking that i was wrong in some way by telling folks thier cars would run better with at least "SOME" back pressure or it would foul out the plugs quicker now

[805ROADKING]

Excellent demonstration Professor Bernoulli !!☺

[groutaone]

@805ROADKING Captain B says always blow it out your pipe, ha ha thanks buddy

[snakesonaplane2]

you should make a video showing how an exhaust crossover helps

[groutaone]

@snakesonaplane2 Hmm, got me thinking

[snakesonaplane2]

@groutaone i always see guys thinking they don't help or they make the rig sound worse but i've seen firsthand in a number or situation where they improve power throughout the rpm range and they give the exhaust a smoother sound, and even though there are dyno test showing they work, a home test like yours would put a lot of people in there place, this one about collectors was friggin awesome

[pulse0000]

Very interesting.Thanks!

[groutaone]

@pulse0000 Thank you

[markterry95]

is that a house reference there? xD

[markterry95]

really cool, thanks for uploading :D

[groutaone]

@markterry95 No problem, it was a fun video to make

[MagicCadillac]

Well, that's really interesting how that thing is working, that's good to know all that.

[groutaone]

@MagicCadillac I wasnt sure how well it would work till I tried it, sure was interesting

[phill903]

That interesting very cool example of the working of a collector.

Thanks for sharing Thumbs Up !!

[groutaone]

@phill903 Thanks, and thanks for the rate too

[500passwords]

very cool informative video buddy :)

damn guitar players never help . lol

thumbs up from 500

[groutaone]

@500passwords I may be paying the guitar dude too much, may have to hire a new helper, thanks for the rate

[tedhaze1]

hey do you think on a 6 cly motor cycle with after market exhaust with 6 individual pipes is not so good ?sounds awesome but i did here 3 into one on each side would be better?guess you vid kinda answers it

[groutaone]

@tedhaze1 I think a collector is always best

[sirkyar]

AWESOME! really interesting

[groutaone]

@sirkyar thanks man

[thestuffz]

more flow and more sound :D

[groutaone]

@thestuffz Brrap, oh wait thats my dirt bike lol
