Video inside an engine

Pretty cool

I'd like to see the same video except with the timing about 8-10 degrees advanced for what's normal for that particular motor and watch it detonate itself to death. See what the explosion looks like compared to a nice even burn.

Looks like a late model hemi? By the valve angles. Mat have put the camera in the second spark plug hole.

When I was in college we had a see through engine. It had a Pyrex glass cylinder and some crazy looking piston and rings. It was cool to watch it go from a rich to a stoic mixture. Ahh the fun we had with that thing and rc 2 stroke fuel 20% nitro. Lol. It would max the dyno when we cranked the timing up and took all the lash out to get a little extra valve time.

Man, Go Pro always coming out with new attachments

That's amazing! Now I see why the valve train is the weak link

Just wish it would have kept going through the exhaust stroke.
