This is what happens with you hit the factor rev limiter. Not only is the #8 piston cracked, you can also see part of #2 ringland is missing. Note to self - stay off of the factory rev limiter! Better note to self - eliminate the factory rev limiter all together with the PMS and use an ignition rev limiter.
A compression test showed 75 psi when this happened.
This is what happens when you disconnect the FMU troubleshooting and not revving past 5000 rpms, and regap the plugs at the same time. You run out of fuel at 5500rpms. #1 cylinder goes very lean and you end up with a hole in the piston. Note to self - do one thing at a time!
A compression test showed 0 psi when this happened. Haha... hmmmm...not funny.
The cylinder wall was not happy with these rings gouging into it.
Another view of my see-though piston. This is not a good preformance option even though the piston is lighter now!
Here is a picture of where some of the piston ended up... that would be sputtered on the rod! the rest of the piston ended up in the oil and went through the whole engine trashing the oil pump as well. The filter didn't stop too much. I guess the rpms had the oil pressure high enough to have the bypass opened.
