How does an anti-lag system work? What is an anti-lag system? In the video I explain an additional type of ALS, which uses a bypass valve sending air to the exhaust manifold in order to maintain the boost levels provided by the turbocharger for the engine. This system is present on some models of the Toyota Celica and some models of the Mitsubishi Evolution. Please feel free to rate, comment, and subscribe!

so they do put the blow off valve into the exhaust..
-
Is this the same as a blow-off valve?
-
Solenoids pull in don't they? unless they want to keep it constantly energized when they want the valve closed xP. I'm just bored. Keep up the great videos!

Do I need to alter ignition timing?

So it double as blowoff/diverter valve apparently, but here a question related to that !
Could this (or any other diverter valve system since they probably are always needed the same time as any anti lag) be used with the ignition delay method of anti lag to not only push more air inside the exhaust manifold and increase the turbo pressure, but more importantly, since the ignition delay method is probably already air rich rather than fuel rich, it would probably not increase the combustion to bring fresh air, but can it be then use to cool down exhaust manifold and turbo ?
I guess that it might need to be done with a heat exchanger around the exhaust manifold to avoiding loosing pressure by cooling the exhaust gas too soon and then inside the turbo itself inject it with the hot gas as two gas flow (to avoid premature cooling down of the exhaust gas), so the time the hot gas transfer its temperature to this cold one and loose too much volume, they are already out of the turbo.
I have no idea if this is possible, so as the engineer, what do you think about that ? -
is Air Bypass Valve and Turbo Pressure Solenoid Valve same thing??
-
escort cosworth work different to this, it uses a larger idle valve and alters the spark timing so the combustion happens in the cylinder however the exhaust valve is open slightly so determation also travels down the manifold through the turbo.

Saw a couple of your videos a while ago on trying to find ways to stop turbo lag.. instead of having a waste gate valve on the exhaust, why not have a waste gate valve for the air that's being spoiled up instead? So you would constantly have the exhaust running through the turbo and have it spooled up but not all the air is going to the engine. Then as soon as you hit the throttle, waste gate closes and the spooled up air gets diverted into the intake. Now I understand that one of the major draw backs of this would be increased turbo temperature.. any other major draw back as to why this hasn't been done yet? (To my knowledge). Thanks in advance!
-
a car with antilag with bypass valve does not whistle when releasing the throttle,right?
-
This guy really fucks with my ADHD
-
I searched about 3 hours and finally I understand
-
In the end this ALS does the same to your exhaust manifold and turbo like the Ignition Delay ALS, but you have to install more parts and add weight, Seems unpractical to me
-
All the cars should have this.

seems like the bypass method is not much a difference to the delayed ignition method right? they all produce the same result by creating combustion in the exhaust manifold. So which is better? why people choose one over the other?
-
You're the GREATEST explainer, thank you for the videos.
-
on a car with an ALS system will the wastegate be venting exess pressure and cause the fluttering we hear on the WRC cars or is that surging (fluttering) coming from the turbo compressor itself
-
hi great video, could you make a video on how turbo flutter works and explain that it comes from the turbo compressor when the Thottle body is closed rather than the wastegate? im tired of having to explain to people who dont know this only to get into a debate and have them try to tell me its from the wastegate itself LOL

i love your videos !!!!!!!!!!!
