Fd Is Dead Again
#1
My FD is dead again While tuning @ around 6500 in 3rd the rear rotor went. The tuner is well know local tuner and knows what he is doing. Sounds like 2 apex seals are toast, need to do a compression check just for fun. What is weird is the was no knock, running 13.2 A/F and only 1.1-1.2 bar. The timing was 13 with 8 split I believe, have to look a datalogit again. I will be taking the motor apart this week to see what happened, untill then it will be a mystery to me. (Pictures soon) I have though of everything and i can't seem to figure out why it would blow. I have the new mazda 2 piece apexs, and all the toleraces where good when I rebuilt it. (mostly new parts) It was only a mild streetported (ports cleaned up)with opened up exhaust ports.
Was seeing full boost @ 5200 on a t-88 34d, with the 22cm exhaust housing.
Guys have any ideas???

What were your a/f's when you blew it? I know that there's a particular car on Okinawa(not my own) that mysteriously destroys apex seals.
If it's any condolensce to you, my entire wiring harness decided to fuse itself to...itself I've got a serious wiring nightmare going on in my car...but at least the engine's good(for now)

My a/f under boost was 11.1 to 11.4 after looking back at the datalogit.
