Piston detonated?

I don't see anything to be too concerned about. How long have you been running E on those injectors? I usually send mine out once a year to get cleaned. Just noticed you're in Jax area too.

The very occasional puff of smoke on start up after sitting for a week but otherwise not at all. Still pulled hard AF on my way home before I checked and then I think the paranoid side of me just immediately freaked out to be honest when I saw it. It's such a quiet motor, even when making power still. And the power feels right if you know what I mean. I'll take a video of it running as soon as I can but no noises or smoke. Compression test was also great on all 8 cylinders.

That would be valve seals. Most of these engines puff at start up. Just nature of the beast. Personally I think it's fine.

I have ID1300x that will be going into the car along with a return style system. For now the fuel system is stock

I’m thinking so too and Mr. Chris Fix himself is also putting my mind at ease

Looks pretty normal to me. In the third photo, that little scratching on it was just me testing out a finger nail to see if it was carbon. It was just a little bit.

That plug looks fine to me. If the strap had been closed up I'd be concerned.

That's fantastic news.....now is the time to button up the fuel system, and make sure you have a properly functioning wideband you can datalog...get that sucker on E85 and let the tuner dial her in. Dial in a pump gas tune.

I wouldn't beat on the car WOT until the above is done. Take full advantage of this second chance. Maybe this motor still has a long life to live.

I currently run dual Zt-3s with the MS3 pnp unit so I’m all about the monitoring. If you see my history, two years ago I blew a motor due to the oil pan being crushed and me not knowing better so this time around I’m being overly careful. And paranoid in this case specifically.

Last night being tired I accidentally turned the motor over/on without the spark plug in the cylinder for half a second and freaked out again thinking I blew it up or hurt it. Mainly because of the noise but just another dumb thing to never do again. Everything was fine but scary for that moment lol. Someone please correct me and tell me if I did in fact royally screw up but so far my research just says it’s a “no-no” and that I was dumb but still ok.

Thank you for the kind words and advice. That is absolutely the plan moving forward. Get the fuel system locked and loaded and then also will get all the intercooler stuff done as a precaution to temps even more. I have everything on hand, just need to install now.

The resolution of those images isn't clear enough to make a fair judgment imo. Could be yes, could be no. Those plugs on the other hand need to be changed out for something in the correct heat range. Tr55 is made for n/a cars. A tr6 would be more ideal.

Based on the pics and then the plugs, I’m gonna say carbon.

Only answer is....

Send it

I just picked up some plugs but will swap them for the TR6s. For some reason I thought the ones I got were good? Thank you for the info. Judging by how it’s running and all the input, I’m going to monitor and keep it going.

This piston came in from a shop that does Hellcats. Would you put this piston back into service?
It’s a shop car not a customers.
I SmoothEd out and ceramic coated it. Personally I would not risk it.

kinda confused by your response...

Bloody thing says file too big to upload. Trust me if you guys could see the picture you would not be running out for a second.

You can click optimize for the resizing. Would love to understand.

There you go! Zoom in...

Detail sucks but you can see the major damage. There’s also scuffs and scrapes in the skirt and ring lands. I coated the skirts with dry film lube after smoothing them out.
I wouldn’t put this back in a daily shut box, never mind a 1,000 + hp race car.
