Coil On Plugs that is. Just got these installed. A few guys on Miataturbo.net were building their own COPS using Corolla or GM coils. Savington there makes this Corolla coil plug and play kit fotr the Miata and doesn't charge enough. Anyway, plugged in as advertised, reduced dwell in Megatune to 3.5ms cranking, 2.5ms running and I'm done. Nice to be able to get behind the head for service now.

The intake pipe is temporary. I'm going to make test different intake pipe lengths when I take it to the dyno next week. We have seen that piep length has a huge effect on power. Just switching from the short 8" pipe I ran at Buttonwillow to this nearly 25" pipe boosted midrange but killed everything over 7000. The way this things runs now untuned, I'm starting to think 155whp is possible once dyno tuned.

Oh yeah, Gordon told me my car was spitting flames on every shift when he followed me at Buttonwillow. The thing sounds really angry. It doesn't rev, it barks. Just amazes me that all this is with 100% stock internals.
