X2 GT, good answer. And an amazing description of how they work. I even learned something. Didn't know the technicals of it, but it makes sense.
We used MSD and Mallory in street/strip cars for the same reason. Acceleration. However, there are hidden benefits that affect mileage and engine wear and tear tho in everyday "Cruising". Far less chance of a misfire, leaving unburnt fuel from a cylinder or two being then blown into the exhaust. When that happens, that fuel is more likely to explode in the exhaust manifold from much hotter gasses and sparks from another cylinder that DID fire correctly. What this does is put a reverse pressure on all the exhuast valves on that bank. Not a good thing. Let alone what you've done to the exhuast. There is thought and theory that when you run these you can run a tad higher compression without the fear of detonation, which also makes sense.
Second advantage is that since you just put fuel into a cylinder and did not get the power from it, mileage suffers. That is common physics.
All in all, put a CD unit in, saves a lot of headaches and is as reliable as the sun.
