WTFOMGBBQ!!!!!!!!!!!
The electrode was still on the plugs, I don't get it.

BTW head gaskets were fine as well.

whiteout 5.0

did debri enter the flowmaster? that is a sick setup its an auto car isnt it?

samseed101

Any chance something got sucked up in there or forced in there with the turbo setup? How good of a filter / screen were you using? If I had to guess, I would say that it may have been a small metal fragment that broke free from the flowmaster after it was cut open.

5IVE.OH

Yep a small piece of slag was prolly the culprit. It's not bad enough to replace the pistons though # 7 looks like it got the worst of it. Fawk what a **** off.

91lxstang

stupid hair dryer project!

TTGreenSN95

see how it is on top of the pistons,funny its the same on both pistons!!!!looks like he is detonating and burning the pistons up.
need more gas less timing???but then agina what do I know???

5IVE.OH

You know I thought the same thing. But there is also pits on the head as well in the exact same locations. I am running 8* timing with the vacuum advance removed on 91 ocatane. So I really doubt it's detonating.

91 octane thats really low on a turbo motor how much boost?
its just a lil funny how its all in one place not all over the piston???
and its the same on both pistons wierd..
by the way your setup is awsum I love what you did......
and you did it all yourself NICE!!!!!!!!!!!!!!!!

5IVE.OH

7.5lbs of boost and 91 octane is the best you get in dumb *** canada. I should be alright with putting it back together or no? Do I need new slugs?

Suprised that something could stay in there long enough to do that, and not ruin everything else.
