Insane when the traffic is coming head on towards the end.

THAT WAS F***ING AWESOME!!!!!! i want those roads! and that subie!

[newbie101]

did u see that exhaust....pop pop fire....i want fire :eek:

[RS-ti_Andy]

hahah yeah! i want fire too!

does anyone know what an anti-lag system is? i know what anti-lag means, but i don't know what is installed to get rid of lag. no lag is one of the reasons i figured i'd be staying with my stock engine in the legacy...i'd rather have a WRX engine, but not having lag helped me out drive a couple WRXs on a groomed snowmobile trail last weekend.

An ALS system requires an air bypass, and generally this is done in one of two ways. The first method is to use a throttle (http://en.wikipedia.org/wiki/Throttle) air bypass; this may be an external bypass valve or a solenoid (http://en.wikipedia.org/wiki/Solenoid) valve which open up the throttle 12-20 degrees (http://en.wikipedia.org/wiki/Degree_%28angle%29). This allows air to bypass the closed throttle and to reach the engine. The second method is to use a bypass valve which feed charge air directly to the exhaust manifold (http://en.wikipedia.org/wiki/Manifold_%28automotive_engineering%29).
The throttle bypass/throttle solenoid system is combined with ignition (http://en.wikipedia.org/wiki/Ignition_system) retardation and slight fuel enrichment (mainly to provide cooling), typically ignition occur at 35-45° ATDC. This late ignition causes very little expansion of the gas in the cylinder; hence the pressure and temperature will still be very high when the exhaust valve opens. At the same time, the amount of torque delivered to the crankshaft (http://en.wikipedia.org/wiki/Crankshaft) will be very small (just enough to keep the engine running). The higher exhaust pressure and temperature combined with the increased mass flow is enough to keep the turbocharger spinning at high speed thus reducing lag. When the throttle is opened up again the ignition and fuel injection goes back to normal operation. Since many engine components are exposed to very high temperatures during ALS operation and also high pressure pulses, this kind of system is very hard on the engine and turbocharger. For the latter not only the high temperatures are a problem but also the uncontrolled turbo speeds which can quickly destroy the turbocharger. In most applications the ALS is automatically shut down when the coolant reaches a temperature of 110-115°C to prevent overheating.

yes.. i hope shops know how to do this when i geta turbo aplication!

[thatguymike]

I'm sure anti-lag roaming around fremont will be a hit with the cops there;)

i hope you have a bunch of extra turbos

Antilag kills motors dead after a very short time. Don't get it unless you have a stack of motors and turbos lying around.

Cool video, i think someone posted this a few months ago..
