Just to note, antilag in rally cars is significantly different that “antilag” on most lower end ECU’s that guys will use for launch. The rally systems are not just retarding timing. They’re a full air bypass system where the turbo cold charge will actually recirculate into the exhaust and fuel will be added normally by retarding timing and then a secondary ignition is used in most cases. It’s a very advanced system and really really cool. It’s now being used in Formula Drift as well for those that don’t follow either. Worth noting because I think your info was a bit misleading.

And remember guys, it is always best to use all of the above limiters on a cold start for maximum results ;)

[CrazyDutchguys]

yeah i have a question
So how do i replace my piston return springs?

[VoidSixx]

Also good to emphasise something between 2-step vs Anti-lag


Yes, 2-step *can* build boost, but it isn't designed to, it's only a side effect. Anti-lag is purely for building/maintaining boost, and will maintain higher boost pressures than 2-step is capable of.

The car community needed this video so badly...

[v.e.]

2:41 Where can I get one of those crazy inflatables? Too funny! Every turbo car should come with one as standard equipment. LOL

[pcandmacturorials]

That Turbo panda at 2:40 is fuckking GOLD Hahahahahahha

1000 HP Supra Anti-Lag FLAMES Turbo SOUND
every supra video ever

[drewkuze]

good expalnation and it was cool to see an hp logic clip at the end

[MrIdidyourmother]

For the love of the car gods, please make a video on afterfires and backfires. Probably one of the biggest mistakes made in youtube comments.

[TractionAndTarmac]

@2:35 THAT WAS MY VIDEO! LMFAOO I GOT MY NAME IN THE DESCRIPTION!!!! LMFAOO

[chris_purves]

All those lovely NOISES just need to fit turbo to my Bluebird now...

It isn't ignition in the hot exhaust, it's ignited by the after fire of the following cylinder otherwise on older cars without all this electrical stuff in them, if you reved it and then turned off the ignition there'd be a constant stream of flames, instead there's just one pop when you turn the ignition back on. The hot exhaust merely flashes the hydrocarbon fuel into a vapour making it much easier to ignite.

If a hot exhaust ignites fuel vapour you'll get a constant stream of flame from down the pipe which will make a very characteristic whoosing noise where as after fire ignition makes a pop or bang. An example of exhaust ignition would be some high end lambo's where you can see that blue flame on the exhaust sometimes under acceleration. That flame also contains a lot of very hot oxygen.

I just realized that I think backfire is when fuel accidentally combusts into the intake of an engine when experiencing bad valve timing or valve float or something like that

A word of warning using the Bee-r or any other ignition cut that uses the same method of cutting ignition which is to ground out the coil and stopping the spark
But the spark has to come oui of the coil regardles as the Bee-r cuts in the middle of a cycle causing a random spark at any point in the cycle.
If you like your engine and don't like DETONATION and your engines lifespan being reduced then take note.
Also If you do use the Bee-r, make sure you have a straight through exhaust as large restrictive silencers tend to explode when full of fuel in them.

What about hard cut limiters or "popcorn" limiters on a diesel engine? Would the risk of damage be the same? I heard it can be bad for the timing belt.

[cobaltlukather]

where did that panda video clip at 2:41 come from?

[TheGolive]

I still can't understand what causes the exhaust pop up when you shift up in new cars like A45 amg and RS3 and the golf R and other RS cars

[Daddimirr]

Ignition cut deadass sounds like a jake brake but with fuel

[dasboseimbusch]

1:16 Damn, that's a beautiful camshaft.
