Took of the head last nite and found 3 damaged pistons. On the intake side looks like some small chunks have disappeared from 1,2, and 3. Still have to drop the pan and take them out, but this is the general prognosis. Luckily I have developed a "broken motor fund" over the last year and can make the repairs without too bad a hit.

 

That sucks man. What is your setup like? How do you think you blew it?

 

that sucks, but props for planning ahead! I was in the midst of building my second block when my current let go.

 

what kind of pistons do you have? What are your plans now?

 

those were JE and I'm looking for one now that is taller. If not then I'll stick these back in.

15psi...I was told that at this boost level or higher, total timing should only be around 20 degrees (full boost).

I thought I was pretty safe. VP 103 gas, took it to the dyno for tuning. I'm gonna try and the head to the shop and pull a piston (too busy) today.

 

Any idea how this happend?? Just "out of nowhere" detonation?

 

bad gas.

 

didnt u hear it the popcorn poping in the engine and u could have just let out of it and go retard your timing some more

 

Is it me or has a lot of FI R's been blowing up these past few weeks......
good luck with the rebuild
