anti lag is great, and its generally acheived by retarding the timing so much that the power stroke overlaps the exhaust and creates combustion in the exhaust. so expanding gasses from combustion in the exhaust drive the turbo. I had this conversation the other day and am trying to figure out a cheap way to do it. the main problem is ou need a decent stall to keep the rpm up enough to stay running. I have never used it under 2500rpm and its allways been with AEM EMS systems. but I want ot try to modify a 2 step and some kind of timing retard to accomplish the same........................ anyway thats plenty to type, I may try it out and if I do I will report back on what I did
Just a word of caution when using this on a stock ignition Buick, the waste spark will KILL your pistons and more. The "combustion" created on the exhaust side will happen twice in a revolution and is not good when the exhaust valve is open.
Some GN racers can get away using a 2-step for a while with a coil pack, but I have seen and replaced many pistons and valves because of it.
ah, good call. diddnt even think of that yet. this would be a big issue. hmmm back to the drawing board.
oh and I have never damaged a turbo using a proper anti-lag setup. even on a street car.
