@@blitzwing1 I do it, but not in front of people to smoke them out, non VGT turbos are gonna smoke at low RPM until you’re in boost and doing a heavy takeoff. Now I do it to people who are dickheads and try to cut people off
So , this can be considered as having an automatic EGR, since the exhaust ports are near to the intake, some part of the gasses are being aspired by the engine = what EGR does. So no problem about emissions tests, it can be considered in the range of the VW's engineers.
Doing exactly this is how I warped my valve in under a few minutes then after putting the manifold back on I could hear that valve making noise and now I can hear the lifter tapping noise and I think I have a broken spring or lifter or both along with that messed up valve which is now causing a misfire!

Well that’s basically how we breath anyways, actually we are worse, we use the same nostrils for intake and exhaust, at least engines have separate ports.

@@jankington216 Its not back pressure thats needed for scavenging, its narrow exhaust pipes. Back pressure is just an unwanted side affect of that. Basically narrow exhaust pipes means the exhaust gas will be forced to travel at higher velocity so it exits the tailpipe while still warm, hot gas moves much easier and quicker. Also the higher velocity of gas aids in the scavenging effect. Having an exhaust pipe too wide gives the gases time to form plugs of cool dense air thats hard to push out causing small loss of power from back pressure funnily enough. As one plug is pushed out another is formed, you can sometimes hear it as a "choof choof" sound at the tailpipe of a small car with a big exhaust, you will also probably notice the exhaust gas is not very warm.

Keep in mind changes in back pressure will affect tuning especially for carburetored engines, you can re-tune to match the new exhaust but thats probably where the myth that you need back pressure comes from, since some poeple probably decreased the back pressure, found it ran like shit and blamed it on lack of back pressure, rather than lack of tuning.
@@jankington216 You want vacuum not back pressure. The phenomenon is misunderstood on why a engine runs better with manifolds or headers.

More efficient engines have scavenging, but that has more to do with your cam than exhaust. If your engine relied purely on your piston to push the air out on the 4th stroke it would hardly run because not all the exhaust is leaving the chamber. In most modern engines for a very brief moment the intake valve and exhaust valve are open at the same time. As the exhaust valve is near closed the intake valve will open to push the remaining exhaust gases out using the intake air because in that time period the exhaust has lost most of its vacuum and the piston is near tdc. This is more apparent on turbo charged cars that have been modified and have a 2-step. That fire that shoots out of the exhaust is caused by this, but obviously this is an extreme case.

Some don’t but most do when you’re at the track running high hp 12 valves they use wooden balls the size of base balls to put in the inlet of the turbos or intake just in case the engine starts doing what’s called running away which is where it’s injectors are hung open or something breaks and they can’t stop it
@@xymaryai8283 they're actually less complicated than gasoline engines. If you've never messed with them, they seem very complex, but once you've actually worked with them for a while, they're extremely basic and easy to understand, more so than gas actually...if its getting fuel, its gonna run. No ignition system, so that's one less entire system to worry about. Only the "modern" ones look complicated, and even then, they just look more complex than they actually are, it's all just emissions stuff and sensors (which most are emissions related anyways)...if it's in your way, remove it...trust me it's not worth fighting around something for an hour when it takes 2 minutes to remove completly. engine design has changed very little since the very first one, once you understand that basic principle, they're all the same

and that is how to make your mom proud !!
always fun to do this. the disel injectors are not on the intake, so that why its still getting fuel by "direct injection"
I was just about to ask how he got it started and revving without an intake manifold with a throttlebody, then i remembered diesels dont use throttlebodies
Some don’t but most do when you’re at the track running high hp 12 valves they use wooden balls the size of base balls to put in the inlet of the turbos or intake just in case the engine starts doing what’s called running away which is where it’s injectors are hung open or something breaks and they can’t stop it
@@spartansoff-roadrecovery5058 I believe engine oil leaking into the cylinders is also a common cause of runaways?
@@Wilma5532 you’d be correct 👍
man, diesels are wacky, i gotta learn how they work
@@xymaryai8283 they're actually less complicated than gasoline engines. If you've never messed with them, they seem very complex, but once you've actually worked with them for a while, they're extremely basic and easy to understand, more so than gas actually...if its getting fuel, its gonna run. No ignition system, so that's one less entire system to worry about. Only the "modern" ones look complicated, and even then, they just look more complex than they actually are, it's all just emissions stuff and sensors (which most are emissions related anyways)...if it's in your way, remove it...trust me it's not worth fighting around something for an hour when it takes 2 minutes to remove completly. engine design has changed very little since the very first one, once you understand that basic principle, they're all the same
The best part of the video is just the hose clamp bouncing around
That hose clamp just hangin on for dear life
Start at 0:15 at put it on 0.25x sounds like a sick beat
Sounds like a nice beat when it’s idling
Now hear me out, let's put velocity stacks on the exhaust ports and see wat happens
Guy 1: I Straight piped my ride!
Guy 2: Oh yeah, well I'm running open headers!
This guy: So, no head?
