Please post a pic of your spark map so we can asses our level of risk.

Did you melt a piston or throw a rod? I'm really sorry to see you lose an entire weekend, but it looks like you have the skills to rebuild her better than ever.

Thanks guys, I started stripping the spare block today. I'm shooting for a rebuild for the next event. I wasn't detonating so I'm thinking a rod failed.

Here is my spark map. It is based on the one posted by Ben:

Hmm. My spark map is pretty conservative but you are using 6-7 more degrees everywhere in boost. I know I'm leaving a lot on the table when it comes to power, but you might have kicked the table over and stolen the chairs.

I think that's one of the funniest ways to put it. Lol

I'm running about 3 degree less at the same boost level he was running was it blew (150kPa). IIRC the rods are more or less the same, but I have a CR of closer to 8.9 and you have a 9.5:1 cr...

But, I would never be running >9.0:1 AFR...which on your logs posted on mt.net show you were hitting between 9.2 and 8.8:1 in boost.

I really think all that extra fuel was washing down the clyinder walls (so contaminated oil and maybe metal/meatl contact from rings) and increasing pressures caused things to break.

I pulled the plugs. They do not indicate a rich mixture.
