who out there is anti lag. im looking into set my car up with it but do not know everything I need to think about when doing this. I know its going to run the turbo hotter and the manifold is going to be cooking. what should I do. how are you using it and what ways are you setting it up.
 
I turned mine off. The affects on the turbo is more than just running a little hotter, done often enough you can toast turbos in short order, melt & burn stuff too.
 
I shouldof worded that different im sorry. I mean what precautions are they taking so the turbo and engine will take the abuse of it.
 
Thats the thing. It cant really take prolong use of antilag without doing serious damage. Our cars dont really need antilag either, unless you have turbos in the 67mm+ range, and even then 2 step/preload(or nitrous w/auto) will get you were you need to be.
 
Not sure you can do anything for safety, it's gonna take its toll. By retarding ignition and richening the afr i believe the EGTs skyrocket. But if you minimize the time spent on the line using it....thats gonna help at least. Cooling the turbo by any means necessary will help. Water cooled chra, maybe an external oil cooler with a fan? Just a couple things i can think of to try and dissipate the intense heat it will be subjected to.
Basically you're getting partial combustion outside of the cylinder(s) and in the exh manifold, im sure you know that but just to reiterate: that puts extreme temps and pressure on the mani, hotside of the turbo, the turbine itself and even things like the o2 sensor take more of a beating.

I can only assume you want it for launching a large turbo with manual tranny? Nitrous will do the same thing, faster, and safer.

I've never tried it, im speaking from knowledge i picked up on the forums and reading elsewhere. Keep that in mind.
As Mello said, exh valves can be damaged as well. Anti-lag is awesome if used right but the risks are high when dealing with several thousand dollars in components.

Edit: If its an AT then run a vac pump/check valve hooked up to the brake booster. No need for antilag and possibly not even nitrous to spool it. Just decent brakes.
 
G'day, I run anti-lag on my VR4 rally car. Yes the dump runs hotter and over a year of rallying I have welded cracks in the dump pipe three times. With an Autronic SMC computer it is set to activate at 5000rpms and stay on for 15 secs. It resets each time I reach 5000rpm. I set the amount of bang by opening the throttle plate a little, I have the air idle disconnected and plugged up, to suit me as a driver. With a larger throttle plate opening the bangs are harder and more aggressive on the exhaust. After setting the throttle plate I teach the computer via the TPS where wot is and where closed is. The engine also exhibits rotational idle and it gets stronger with more throttle plate opening. The computer goes TPS closed, but the MAP sensor says there is manifold pressure so you need fuel, the computer says throttle plate closed, no thanks. The engine idles rrump, rrump,rrump. It also pushes the car into corners a bit so I have to brake hard.

^^^Isn't rally where antilag was essentially born/became prolific? I've read that, don't know if its true or not.
 
seems like very unneeded abuse. I will be looking into just tuning for 2 step. I will also be running hx40 manual trans. awd. now on link how do you have the 2 step set. at what rpm/tune/afr/timing. or can I just set the 2 step rpm I want. don't know how involved you can get with the launch settings.
 
You can do just about the same thing without killing your turbo by setting up a 2-step and nlts. Like with ecmlink! But YA I would say anti-lag is more for rally or big turbo drag cars maybe. I wouldn't be worried about using it on a dd/ww. ;)
 
dsmecu.com probably offers the cheapest antilag you can currently buy, and rotational idle for these cars.

I've used both and can say that my turbo was just fine after removing it. No I didn't tear it down to inspect it for damage but I daily drive my car and beat the ever living dog snot out of it every time I drive it. A ball bearing turbo will stand up to antilag better than a journal bearing will so that is something to keep in mind.

I'd like to add that if you're afraid of breaking things and spending money to replace them, you're in the wrong game. Rally teams used to keep spare turbos with them so that when one died they could quickly change it. The turbo and exhaust parts take the majority of the abuse. Another thing to keep in mind is the violent RPM changes are probably not so good for the crank/harmonic balancer. I'm sure something will toast there over time.

The **right way to do antilag is to inject fresh air into the exhaust manifold, retard the timing, and add some fuel.
