LuckyX2 is an unknown quantity at this point
Well, my dyno was today. Went well, until I started getting what I think was spark blowout around 20psi.

Still, I managed to pull out 404whp and 338ftlbs at only 20psi and 6500rpm. I think that's a pretty good sign that 550-600whp is in there somewhere with 25-30psi and 9k rpm.

Anyway, here's the printout I have that's closest to the 404whp run. I wound up not printing that one amongst scrambling to figure out why spark was cutting out.


The fluctuation is the closed loop boost controller. Never got around to fixing that.


Here's one of my earlier pulls where I was testing just the low lobe so I had the switch point set high at 5k.


Look at that jump in torque when it switches. wow.

Finally, here's a log of the backfires.


You can see AFR is good (12.2) leading into the two lean spikes that were accompanied by backfires so I don't think it was fueling. My guess is spark blowout, I'm gonna check my plugs. Thoughts?
