So, I'm guessing detonation city ruined this motor? More close up pics of the pistons please. I wanna run more boost.
|
No Detonation, just overpowered the rods
EDIT: Battery in camera is dead. Pistons look really good, as well as the rings. He was putting 273hp to the ground. |

Don't say that. That's not what I want to hear. :vash:
I expected the rings to fail first, but they were excellent as well. The worst thing about pistons was a slight bit of carbon build up on one of them. Where's Waldo? |
Meh, I'm gonna tell myself that detonation bent those rods. :) Who's Waldo? What kind of AFR's did he tune for in full boost? I still think detonation did it.....
|
And did it bend all four rods? I can tell two are bent from the pics. Did he have a coolant reroute? When did this happen? At 7K RPMs 25 minutes into a track session or what? What timing map was he running?

Fine Pat, for you piece of mind we will call it detonation. You have never did one of those where's waldo pictures? Note: No signs of detonation were seen. |

Let me know if you need rods as I only have 5 sets left.. I can hook you up and ship them out next week. 270hp is a lot of power for an NB motor in **MY** opinion.

I already have all the parts for the rebuild though. Pat, If it doesn't look like all four rods are bent it is an illusion....they are bent:giggle:. Some more significantly then others. EDIT: Dang it, 300 posts. |
Wow. This really makes me want to measure my rods.

Funny, cause I almost turned up the boost earlier after riding around this morning.

As for the broken motor... that's what you get for using a homosexual fuel rail. |
This is my car and there wasn't any detonation ever much less anywhere near the time we started hearing the cool ticking noises. Bryce and I were driving (Spiritedly) from Houston to Fredricksburg to the Texas Miata Roundup. Bryce did a few 80mph-140mph pulls (maybe I'll get him to pay for half the build);) and when we slowed to exit the freeway we heard the ticking. We were pretty close to BEGi so I called Stef and she told us to bring it by. My Dyno chart is on here somewhere but if I remember correctly at full boost (13psi) my AFRs are around 12.6 I think. Don't quote me. The Gay fuel rail is a new addition and wasn't on the car when the rods bent. Corky told me not to tune past 12psi on stock internals but I insisted on 13psi so I got what I deserved, a BadAss engine build. Don't tell my wife, she still thinks that it was an accident!
|
so this is where I sum up some details:
2003 10:1 compression motor 13 psi 12.6 AFR GT2860 Xede controlling it. also I'll note here that my car pings ever so slightly if I use too aggressive timing at 10 psi... on 93 pump gas... |
could have been bad gas.... or diesel...
|
hurry, everyone in texas blow up their stock motor so hustler can't flex on you. lol
