Anti Lag

[TheToby]

I did some very general reading on anti lag systems and i was wondering, is anyone here running anti lag?
Can anyone inform me in detail about exactly how they work??
thanks!

i COULD search it, but im sure there are some people who havnt heard of it who might find it interesting!

im sure everyone can google it up... even i can

from the site above, its a system that retards the ignition timing to keep the turbo running. So you dont have to wait till the turbo to spool again to get the power you want.

i was wondering.
if you have a standalone ecu, could you set up an anti lag setup and a normal street setup and change between the 2 of them?

[know1]

even if you could would you want to? I read that anti lag systems chew up and spit out exhaust manifolds

keep in mind the wear on the turbo increases since the turbo is spooled NON-STOP

Give Rocket Rally a call. Their rally car has it i beleive. Patr can most likely answer most all of ur questions. I hear he's an expert!

And if you still have cats...it eats those up quicker as well.

We have a bunch of cars with Antilag. You really would not want it on the street. It will wear out your turbo quickly.

To answer your question, yes, with a standlaone EM system you can run anti-lag, something like Autronic, Motec, Link etc.

[TheToby]

oh yeah i wouldnt think about running it on the street.
i was just wondering if you could 'switch' it on and off.

thanks tora!

p.s. how quickly would it wear out a turbo?

[Splinter]

You're gonna get like 8mpg running antilag

It'll ruin your turbo, your cats, your exhaust, and if any cop ever happens to see you with it on, its gonna be an instant VI (flames popping out your exhaust = bad)

who needs an exhaust anyways?!

[RX Renesis]

caless ftw... but even if it's catless it'll destroy the exhaust system? how so?

[FunkMasta]

your exhaust isn't made to have fuel explode in it all the time your engine is running...

It won't destroy your exhaust in 100kms, it will last a long time, unless you have a cat, that will get DEstroyed. Anyways, ALS should be a race only application, not for street.

[patr]

the rally cars all have cats in them. They just last 1000k or so, thats all, and we make them quick-release because we replace them every race or two.

a proper system als doesn't eat up fuel, it actually runs the same fuel, just cuts ignition timing so it hits the turbo unburnt

other als systems have their own injector (which does eat fuel), and there are other types as well

competition cars get 3MPG anyways on boost...

we DO NOT run the als system on tranits/road sections, in order to save the turbo, the car, etc.

manifolds get beat, turbos get beat, exhaust gets beat, and cats wear out fast.

there are many variations on ALS trigerring, but most if not all are switchable. as well, when active, your idle will be around 2000 rpm and most guys who first start out with it crash on slow corners/hairpins because the car goes even when their foot is not on the gas.

Anyone that puts this on a street car is only doing it because they a) dont know the consequences, or b) don't care about the consequences. And they a) dont know what it does and b) dont know why they need it. But most importantly, dont do it with a stock up-pipe or an EGT or front O2 sensor... it will end up in the turbo.

That being said, for proper applications, we set this up all the time.

Hm, interesting.

Paul_S was telling me that he got less than 10mpg when his ALS was turned on

I would have thought that having an increased idle would significantly affect fuel consumption

[patr]

with SOME systems, holding throttle at 3000 rpm with ALS off ~= fuel used as with ALS on at 3000 rpm

others use dedicated injectors and/or add extra fuel for cooling effect, etc.

it all depends on how you set it up. if you are worried about mileage, ALS should not be on your list of items to have. Like I said, 3MPG on the throttle.

[Splinter]

I think if you're worried about mileage, a performance built subaru is not on your list of things to have

Im just saying that its another reason you wouldnt want to drive around with it on.

get ready to go through turbos like a baby goes through diapers.

[Chp_Stix]

it kills turbos and it isnt easy to just turn on and off the reason rally cars go bang bang when they are in nuetral.... it is dumping gas no spark gas gets hot spools turbo and you have boost but it kills turbos big time

patr already descibed it in detail...I'd take his word boys.

[Chp_Stix]

i didnt read it through, so then i answered and looked up saw patr and was like NM he got it.... hehe reading>me

It's not practical (or legal) for the streets here, although it seems to be pretty popular in Australia for some reason...
