I'm pretty sure the Evo VII RS (not sure about other models) has anti-lag as I saw one on sale that included it in the description. Do the european evo VIIIs or japanese evo VIIIs have any form of anti-lag? If so, how could I stick it on my USDM Evo VIII?

ez - people are going to jump in and ask you why you want anti-lag and if you know all the risks. can you let us know up front if you already know or care to hear about the problems with anti-lag, or if all you really want to know how to get an ALS working?

I know most the possible side effects but you can extrapolate if you want. I'm just curious why they have them on the Evo VIIs then? Cuz if they're on those then it must be a mild form of ALS, otherwise I don't see why they would be on a street car. I asked a guy who has one and he said

"If you look at a JDM Evo 7, there is an aluminum bellow piping protruding from the runners on top of the exhaust manifold leading to the intake. The intake diverts air between shifts to the exhaust path of the turbo to help keep the turbo spooled up. The system works especially well with an aftermarket ECU with anti-lag programming.

Not sure why the USDM Evo 8 doesn't have it. Perhaps trying to keep cost down."

i was informed that even if there is an antilag breather set up on them they're not tuned for it and the plumbing isn't fully connected or something. any if you do a search there's many other threads on this and how antilag works and the specifics on what was offered on different model cars.

Wasn't that an aftermarket ALS system included with that VII? I didn't think that antilag was standard on _any_ production evo.

the autronic and i think the aem also has als

it is a form of anti lag, but only a basic setup, nothing like you get with a standalone. all it does is pass a small about of boost into the manifold when you come off the throttle. the theory is right, but you need to do it on a bigger sacale to make any real effect! the good side to this antilag as to bang-bang types is it is much less harmful to the turbo. the best solution is to run the two systems together (hehe). you will have NO lag, and NO turbo after a while!

thanks Chris.

Anti-lag was definitely on the VII, it just wasn't "used". It had to be on for homologation purposes.

'SToker Kit. That's your anti-lag kit right there.

i like how Forester xt is setup, there's absolutely no lag whatsoever on that car.

Would be nice to have a 2 stage N20.

Engage for 0 RPM to 3000 RPM, then another one engages at 5000 RPM onto 7000 RPM.

Direct port, of course with CPU A/F reading/self adjust/knock sensor/auto shot off.

That would be worth the money.

yeah that sounds tight! Or just have one for 0 to 3000 rpms with a big **** turbo to take over 3000 to whenever. We are on the same page. Pwer is king.

well, big turbos boost at 4000 RPM or so and up.

Imagine the dual stage n20. It'll kick in when you launch, then turbo kicks in, then n20 kicks in again.

Man, thinking about that just makes me feel all tingley.

Then have the first stage shut off @ 4000 rpm and have the second shot hit with the bigger turbo from 4000 on. Wow!! Sign me up for plokivos's proposal, as a matter of fact I will take two systems.
