    I've used the NGK R plugs on a TON of boosted engines. I can't say what the LS2 coils will support. It would be neat to see how much cylinder pressure they can take before blowing out.

    I actually had the spark jumping three quarters of an inch. Those coils usually like 4.5 of dwell time

    BKR7E gapped at .032" and E85 at 14psi on a 408 SBC so far no issues at 28° timing with LS1 coils and dwell set to 4.3ms.

    I had the spark plug gap at.035 and when I had about 17 pounds of boost I think I was getting miss fires. It felt like the engine couldn't go any faster at 6500 RPM
