Yeah, once the engine's out of the car.

Water does use up space. A nozzle spraying too much could easily overcompress the chambers.

You sound like me - talking through what-if scenarios and trying to reverse engineer the situation to identify the problem. I've been doing that for the last week.

That's what I'm leaning towards right now, except e85 is basically non-existant in SoCal. There's a 76 station not too far away that sells 100 octane at the pump.

I've always been against using meth because the few times something goes wrong, it goes wrong big time.

Probably not, but like Shiv said above, meth has major benefits at the track. I'm most attracted to the cooling aspects. If I do keep using it I'll make some or all of the following changes:
- locate meth tank in trunk (isolate line and pump from the engine heat)
- more restrictive nozzle
- lower max boost
- different tune???

Can you explain a little more, Mofo? I don't understand how that would cause engine failure unless you mean all the coolant leaked out and the engine overheated. I'm confident this wasn't the case since there was no fluid leaking of any kind.

I wish, but I wouldn't have wanted to have my laptop out on the track with me anyway since it was a road course.

Sorry for your bad experience. Sometimes running street cars on tracks can be a learning process.

I don't want to start a war, but since I genuinely don't know, what kind of additional failsafes are available besides a FSB with an integrated tune like the JB4? I thought the PROcede operated on the same basic principle.

Is there anyway to identify the root cause, even after the head is lifted? By that I mean, if it is a cracked piston, what caused it to crack, etc?

Me either - this last week has been agonizing waiting for answers. I'm not even sure my clutch is toast as it could just be the master cylinder. I just figured that given the situation, I might as well start with a new clutch to match the new engine. I'm just glad I really liked this car to begin with.

Dunno yet, but I plan on taking lots of pictures to try and help others learn from my misfortune.
