Something cool I learned today, called gas porting, where you drill multiple small holes around the top of the piston. This allows for the rings to expand more than normal, allowing you to use a smaller ring package. This smaller ring package decreases resistance in the engine, less resistance means higher RPM higher RPM means mo' powaaaaaaaa! This is a common tactic in almost every motorsport (example shown is from a small block chevy)

  • Does that mean my engine won't blow if I ignore the danger to the manifold warning?

  • I've sort of known about this for a while but never seen it in use. Seems more interesting than I anticipated when you put things like that though.

  • I think you'd find this engineering quite interesting

    • Thanks. That's very interesting, I had no idea. I need a road car like this! I wonder how many road cars actually do use this technology

    • I'm curious as well, I know motorcycles have used this for years, that's how they are able to Rev to 15,000rpm, but I would think that some high end super cars have used this as well!

  • That would also be very cool. I do also love big capacity low revving engines

  • looks a little better than the last piston you posted...
