so your saying you want to sit at a light backfiring and shooting flames but you don't want to have to rev the car to build boost. are you under the impression that this is what anti lag will do for you.

 

The way I understand it is that you can have antilag to varying degrees. Some of the lower budget guys I race with set theirs to run ~8psi when off the throttle or about 1/2 the boost at WOT. You can get more aggressive with the timing/fueling and get the turbo to spool a bit further, but even the aggressive setups that I've seen locally don't have the turbo making more than 12psi or so when off throttle. Keep in mind these guys also use a launch control feature, so at the starting line they're banging the rev limiter at 5k and are making boost. The real time savings from anti-lag comes from being able to pull out of each and every corner on the race course.

Basically...if you're wanting to race (and have a better chance at winning), you'll want to rev the car up...even if you are using antilag. The car and the turbo were designed to be revved so have fun winding it out (at a track).

i think he has been watching too many Internet videos. anti lag is for race cars you would look like an absolute *** driving around like that. i dont think it is possible with the stock ecu. don't get your panties in a bunch i know the difference between anti lag ,a two step and nlts mod. damn how did i get drawn to this, i must be tired.

 

I was thinking along the same lines. The only foks I know running ALS are all on aftermarket standalone ECUs.

he's saying he wants 30psi of boost at 100rpm

i'm saying, this guy needs to go to back to school

 

When at 12psi for antilag setup on the evo what rpm would the car be idiling at. Will the car be backfiring alot while idling?

 

..

 

Nah.

 

i'm sorry man, i don't mean to offend you, but this thread is a train wreck.


the fact that you're even asking this question, means you have no clue how antilag works or is controlled. you should google it, read up all that you can, then come back and ask some coherent questions.

 

I guess the whole rpm thing skipped my mind. It kind of has turned into a train wreck.

 

p.s. you don't have true antilag system armed at all times.

 

I know. Only if you have money to replace parts often.

 

Are you kidding me??! I went to the WRC Germany race a month back and the Evos running anti-lag sound literally like machine guns while just idling with the anit-lag on. Not only does it sound like a machine gun, it's as loud as one.

Also, you know that power = (f)torque, rpm. That would mean power is a function of torque and rpm. If you want to use english units, hp = (tq(ft-lbs) x rpms)/5252. torque itself is a function of rpm. ****, I'll just get to the poinit, even with 10psi of boost at idle, you're probably still only making like 30hp. You NEED REVS to make power.

Go do a search on anti-lag in rally cars and you'll learn a lot. Oh yeah, the WRC teams replace their turbos after every race weekend.

 

rev limter is real anti-lag. Real anti lag will destroy your turbo. All jdm come wiht real anti-lag piping mounted on the exhaust manifold.

 

Real Antilag is ignition based not fuel cut based. Log your car on the 2 step and you will see the only reason ignition timing is pulled is becuase of a little knock. 2 step it with racegas in the tank and the timing stays well positive (depending on tune) in the teen range.

The 2 types of "real" antilag are Hardware based and purely ECU (like AEM and Autronic to name a few).
