How much boost are these head gaskets supposed to take?? Are you confident that this won't happen again if you simply replace the head gaskets?

you said the coolant got in through the air intake, coolant dont compress and it has to go somewhere. if you didnt break a rod or any other mechanical damage from trying to compress water then you sould be able to clean it up and be fine with new gaskets. if the gasket blew and that caused the coolant then thats a different story

Bxx and Saar helped me figure this one out. AFR before detonation was low 13s. The target AFR is 12.5.

The way I tuned, I set the un-tuned area of the map (>3psi) to be very rich (lower than 12.5AFR). Then a program called VE Analyzer Live makes adjustments to the VE table while driving using feedback from the WBo2. It updates the table on the Megasquirt every 5 seconds. My guess is that it dropped a VE number too low and within that 5 second window, I had a pre-detonation. If not pre-detonation, just some insanely high cylinder temps. I think robert called it when he said it detonated off of the metal on the head gasket.

I could spend 150 bones on the MLS headgaskets.

I could get them in any thickness. I would want thicker gaskets to lower my compression ratio. They also take 2 weeks...

Or OEM replacements are $50....

Now I'm sure you read the entire 30 some pages of my build thread and know that I had to use the 3100 upper intake manifold so I could use a cable driven throttle body...

You did read the whole thing right?

The minute you put any 3100 part on the motor, it'* a major FAIL. I believe it'* all that intake manifold'* fault.

I read some....of it.
