it isnt for emissions

how can it be for emissions when it doesnt work unless activated by solenoid due to ti being controlled by vac

and why do rs cars pass emission when sas doesnt come on them?

sas is no form of egr or emissions based system

it is secondary air system

it sends excessive pressure back into the exhaust manifold to help turbo stay spooled and also keep it cool at the sae time, but it cannot be active unless ecu settings have been enabled

just becuase thepipes come off the manifold doesnt mean its for emissions, yes exhaust gases go up to the valve but thats it, theres no where else they can go as the other pipe off the valve is on the boost hose and we all know the exhaust gases dont go into the boost hose else all are hoses and throttle and inlet be black inside

Yep, ok, EGR anti-lag is for emissions and SAS is anti-lag. Got it. Every day is a school day on the MLR.

hence my point about not using EGR when talking about anti lag.... EGR is there for emissions (NOx emission) control and has nothing to do with anti lag. Yes, a similar valve is used for SAS system..

SAS is there for anti lag, specifically for grN homologation purposes.

if you do not believe me read the service manual..

I only used it in the original post as I have heard/seen it used to describe a particular ALS configuration, this...

...might explain it though.

I'd still like to see some sort of configuration for "EGR" ALS and understand how it differs to the jacked throttle and fresh air methods!

Egr valve is under the throttle body on models that have it , 7s onwards

There is no such thing as "EGR" ALS !

There is traditional ALS with various ways of passing more air through the TB;
ISCV - GrpN Evos
Throttle jackers
Modified 2nd idle valve - WRC Escort
ALS servo valve - Tibuc
etc

EGR (motorsport) aka SAS
This, I think, operates when ALS is disabled due to low throttle position. The EGR(MS) valve opens and diverts "spare" boosted air to the exhaust manifold. Add bit of fuel and the turbo remains "warm"

My VII RS had SAS before I changed manifold everything in engine bay was same as my IX FQ320 and GT other than Mivec. I still run anti lag tho with a throttle kicker

yeah... but the best detail in the pic is the fact that the turbo is turned around 180 deg and the exhaust goes over the gearbox..
