EVO 6 Build up - USA style

The exhaust will be custom built. The tuning will be done off the stock ECU. AND the ANTI-LAG will be turned on
Once the owner is comfortable with that we'll look at bigger turbos. It's very possible that it will go that way.

All Ripped apart
Buschur Standard Intercooler Hugeness. Had to make all my own mounting brackets.
The Intercooler pipe and Intake are a tight squeeze. The master cyclinder for the brakes is REALLY close to the throttle body on the EVO 6. Made for a very tight fit, but it worked. And the intake wants to slam into the hood if it's not aligned just right. But the stock routing SUCKS. The intake comes up by the strut mount normally.

i love the 6's such a great looking car.. well that and I'm partial to the 3's but thats just me...

The ignition timing is retarded with 25-30° or more and the air/fuel mixture is made richer at low throttle opening and low load. With the ignition timing delayed, the air/fuel mixture reaches the exhaust tubes mostly unburned and because the exhaust system’s temperature is higher than the flash point of the air/fuel mix, the unburned fuel explodes in the exhaust tubes. The turbo is accelerated by the increased temperature/pressure and the rotational speed of the turbo is kept high. While ALS is engaged, full boost is available the moment the throttle is opened.

man.. that thing is bad ***.. soo sweet. Im just wondering, lets say if I didnt care about having a road legal evo at all.. and just wanted it for autox. Would I be able to easily have one of these imported to do so?

Each car is different when you import them, and it depends on where you live. But yes you could do a race only car.
This car's anti-lag is sweet because it has the air pluming into the exhaust manifold. That way when the throttle plate is closed the the air is just routed into the manifold. Mix with extra fuel dumped in and hot metal... you get explosions in the manifold that spin the turbo.
Hoping to button things up and take it for a drive tonight. Then I need to do the cams and headstuds this weekend. By next week it should be ready to have the exhaust made and taken in to have the ECU retuned and the Anti-Lag turned ON! Bang-Bang.

also the antilag is not powered by the uncombusted fuel alone, it also needs air. this is when then antilag boses come in, which are fed from the bov purge air. the an alternate meathod of breathing is a throttle kicker, which as previously mentioned keeps the throttle plate open slightly in order to pass air through the head for the misfire combustion.

Anti-lag
From Wikipedia, the free encyclopedia
Jump to: navigation, search
Anti-lag, (often incorrectly called a Misfiring System), is a system used on WRC rally cars to completely eliminate turbo lag. It is a feature of the engine management system. WRC cars are fitted with a class mandated restrictor on the turbocharger inlet and this increases turbo lag significantly. Because of the pressure drop across the restriction, the pressure ratio for a given boost level is much higher and the turbocharger must spin a lot faster to produce the same boost as before.
Anti-lag effectively increases the mass of exhaust fed to the turbocharger. This is typically done by retarding spark timing to a point where most of the combustion happens in the exhaust manifold, typically around 40° ATDC. At the same time more air must be added, this can either be done by the use of a throttle bypass valve or a throttle stop solenoid. When anti-lag is switched on it is typically active when the throttle is closed, and when the throttle is opened the spark timing is resumed to normal.
Exhaust temperatures produced by this system are phenomenal but they can be controlled by varying the amount of fuel injected while anti lag is active; a richer mixture lowers the temperature. Anti-lag is typically only used on race cars because it can shorten the turbocharger service life down to impractical periods for street use. The turbine blade life is drastically reduced, and the entire exhaust system is put into shock, which can lead to explosion or fire. Rally cars generally change turbochargers every chance they get to do so.
As a note, all Subaru Impreza WRX STi (and STI) and Misubishi Lancer Evolutions are equipped with the mechanical components of an Anti Lag System because FIA rules require complete homogulation with street cars ( only until 1998, newer "WRC" class cars do not have true street going versions. By way of example the roadgoing STi on the American market has 2.5L engine which is 25% larger then the engine used by Subaru to rally), the STi sold in Europe has a 2.0L engine like the WRC car. These cars, however, do not carry the computer or software necessary to activate the system, ( the computer software is the chief component of any anti-lag system).
