People have been touting the LS1 coils for a LONG time yet they only produce ~60mj. LS2 coils require less dwell time and pump out 125mj. I don't know about the Bosch coils. Still waiting that phonecall back. The reason for the swap is pure experiment. On the Dyno Dave and I would make small changes to the L and pick up BIG gains. There are two reasons for that. The coils aren't pumping out enough power to light the mix, or my engine is just very sensitive to AF's. It could honestly be either one, OR it could even be weak wires. Plan is to build new wires and get on the dyno with the new new injectors. Run her for a baseline then swap the wires. Run her again and see if there is any difference. Swap the coils and use the same brand wires and run her again see if there is a difference in power. Then sell whatever setup I choose as it would be an incredibly sexy, almost bolt on ignition system for anyone with a standalone.

As for the air filter, with your fab skills, I think a single filter with a nice custom box around it would do nicely.

Pros:
1. Quicker replacement / cleaning
2. Easier to build box for it
3. Less "cluttered" engine bay
4. Less weight (you could potentially reduce the piping without affecting performance)

Cons:
1. Less surface area for filtration (correct me if I'm wrong, but it looks like if you measured the two vs the one, two has more surface area)
2. Time... you only have 94 days
3. Single POF (point of failure)

Thats my two cents on it. If it were me, I'd probably keep the twin setup.... for now.

I think for the time being I'm going to keep the twin setup as I can run her just fine with it as is. If there's time, then I'll go and fab up the single setup as I agree, I think it would be a little neater. I'm not sure about a plexi top though, I think getting enough air in there would be a little difficult without cutting up the bulkhead. We'll see, I've got 94 days.
