Just for a recap the engine was turning 7000RPM when the power graph took a nosedive, and the engine made a "funny" noise, those vee shaped grooves are where the wrist pin was sawing though the cylinder!

OMFG. I have tears in my eyes. I hope to never see an engine of mine looking anything remotely like that.
OK, I have an Idea. How about selling pieces to cushion the budget. Since it was my idea, I would like the cylinder. Let me know the price. |

Sorry I like to keep these little trinkets, I didnt take apic, but I noticed a hole punched in the side of the oil pump too. At least we have a coupla extra 930and GT3 oil pumps handy. Thats not my engine, Its my friend Billys' It feels like mine though, I have built that engine myself more than once, and have hours of blood sweat and skinned knuckles invested in the car.. |

Been there with the JEs...
It always happens right at 7K too. They must not have been reinforced skirts. I had it happen to a customers engine last year at the track, cleaned the whole thing out and there were no other issues except plain old piston failure... It doesn't happen often but when it does its serious bad news... Crazy thing is that sometimes I run crazy piston speeds and it doesn't happen... Then on a mild engine it shows up. Now I reinforce all the skirts and use the lightest pins they offer. |
