Pics of my blown motor
One apex seal to break it all, and in the darkness I weep:
as you can see, this is a 2 peice apex seal that was turned into a 3 peice.
Where Is the third peice? Nobody knows, but it sure decided to write a farewell note on my housing. By looking at it I think Pineapple racing gave me a new one, now a new peice of scrap
Oh, well, look at that! This apex seal didn't really want to go, so it felt the need to kiss my rotor goodbye
A wall of car parts
She detonated with no warning. 11:1 AF ratio on the meter, conservative timing, trailing plugs were also disabled, and she spat an apex seal. I'm wondering if I heard detonation, or the apex seal just letting go from a previous ping from an ignition problem that I fixed 3 weeks ago. It only hit 75 on the PFC commander.
I havent even checked to see if my turbos are ok either. *sigh* Nows a time to do a full restoration job on the car.

Sounds like something from lord of the rings: "One apex seal to break it all, and in the darkness I weep"
A few thoughts:
(1) You definitely need to trace down why it blew. Fuel filter? Injector? Fuel Diffusers? Wiring harness problem? If you are running a PFC, resistors?
(2) Water injection is a lifesaver, look into it.
(3) Every time a v8 goes into an rx-7, a kitten dies.

Back on topic: hey dude, I live in San Berardino, right up the road from you. What's up with your luck/setup? It sucks to hear your motor die but **** man, engines don't die for no reason at all.... 11:1 A/F seems kind of aggressive on 12 psi IMHO. Rebuild that focker and have it tuned. Water injection? What are your power goals again..? You don't need that for a "reasonable" street car IMHO.

why did you disable your trailing plugs?

Your rotor is far from gone. The main thing is that your seal grooves are unaffected and still within spec. That small dimple is too small to worry about changing your compression or worrying about hot spots. You avoid hot spots by keeping carbon build-up down. You would be surprised at what can actually be re-used and still provide excellent service life.
