klyfax Posted June 10, 2012 Share Posted June 10, 2012 (edited) Knowing this topic is a month old, I will reply to it. Anti-lag (AL) and Launch Control (LC) is NOT the same. Anti-Lag can melt down an entire engine in seconds, that is why I reply.LC is a system that boost up the turbo when holding still. There are 2 systems. One that uses fuel to control the RPM while doing LC, and one that uses the ignition to control RPM.The one that uses fuel to control RPM, works almost like a normal RPM limiter, set to where ever you want. Gives you full boost around 6000 rpm. The other system, you have, most likely seen, or heard. It gives fuel based on the fuel mapping. But the ignition is set to spark very close, or even in the exhaust stroke, in order to get the explosion to spool up the turbo. And its set to cut some of the sparks, so there is more fuel and air in the exhaust manifold to explode. Its gives you full boost with a TD04 around 2500-3000 rpm. When holding still. And it gives very loud bangs from the exhaust, and a lot of flames. AL is a system that keep the turbo up and running then you release the throttle and starting braking for a turn. When you get out of the turn and give some throttle, the AL system gives you full boost at once. No spooling up the turbo when exiting a turn. It is very very hard on the turbo and the engine. Rally cars uses it, but they have titanium exhaust valves, and jet engine steel in the turbo. Very very costly!When you releases the throttle and hit the brake, the AL system gives a little throttle, gives less fuel than map, and adjust the ignition so the sparks comes in the exhaust stroke. This gives very high pressure in the exhaust manifold, and very high temperature as well. Over 1200 degrees Celsius (2200 degrees Fahrenheit), in the exhaust stroke and the manifold. It melts down regulars turbo's and exhaust valves in seconds. And the rest of the engine is stressed very hard. the pops and flames then they braking is the AL working. Most of the starting cars also uses LC.@1.32 a Ford goes by, the camera man zooms in on the exhaust. The back silencer is glowing red. And that is the back of the exhaust, think about what temperatures the turbo has. That heat is made by the AL system. Very Very hard on the engine. Dont ever use it on a normal road car!!!!!Hope it makes sense... Edited June 10, 2012 by klyfax Quote Link to post Share on other sites
