installing a flame thrower kit and wondering if this will do harm.... ok so instructions say to tap into "the coil pack" im assuming it only means to do one set of coil packs and from here on when i push the button to kill the ignition from that set of coil packs will this do any harm to my motor as only one side will be firing? i know it will bog my motor down and stall it but i am supposed to release the button right before it stalls out...just wondering if this will do any damage? from what i can understand all that will happen is the car wiull bog down to die as one side will flood with gas and the other side will try fire a few times but bog down too correct? maybe my 02 sensors will get damaged? i dont have cats nor a real "muffler" slp LM....
Wow I love flame thrower kits but they are a pain to get working with an EFI system let alone a multiple coil pack system. When you bought it did you mention it was for an LS1? What kit is it?
With the old distributor systems it was easy. The kill switch stops ALL spark and dumps raw fuel through the engine and out the pipes to be lit by the additional plug(s) in the tail pipe. You just have to rev the engine (to like 5000) and hit the kill switch, the RPM's will fall and you have to get off the switch before the engine stalls. I have no idea how you are going to interrupt the entire ignition system without a fancy relay type circuit. Good luck and post video if you get it working.

yeah i would agree.. pick up a coil at autozone for 15 bucks of whatever an off the shelf coil pack goes for and wire it up with that. Make sure your tips go past your bumper a little ways.. plastic melts easy

First: you will have to kill all the coils to make it work.
Second: the way flame thrower system normally works you would rev the engine and cut the ignition to make the flames come out. This won't work with an injected car because the PCM cuts the fuel while the engine is coasting down to reduce emisions. No fuel = no flames.
Third: the raw fuel in the exhaust will damage the O2 sensors and the cats.
If you want a flame thrower set-up. Go buy a 50 Mercury.

I've seen a few setups on other boards on a late model F-body. But like stated earlier, they had a seperate spark and fuel system to make it work. Sounds like you are over your head on this project though and should move onto something a little less difficult and not against the law. If you decide to try it, make sure you post videos of the destruction. 
I think Ive heard of this working with exhaust systems like the TSP duals and LTs because the spark would ignite the gasses that the cats would have caught. If this works it might be easier because all you need is the spark plug/s at the end of the pipes and you wont have to worry about cutting off fuel. I might be wrong though try giving it a search and see what you find.

+1 on seperate coil and propane. You'd probably only need the coil to fire once, anyways. You could use an old neon transformer and stick a spark plug hooked up to it in the exhaust, too.
