Grooves in the squish area of the combustion chamber
https://www.jeremiahsviolins.com/grooves.htm
Anyone done this? I'm curious. I would love to do this but my car is too nice. |
Ah, I posted about this way back when when it was new, who knows, not me. Someone more clever will have to come along and see. I believe Larry is having this done on his saturn.
However, it might be worth noting that Hondas don't really have quench spaces, at least not D, B, H, or F series Hondas. I haven't seen a K or L taken apart that I know of but I don't they changed their basic head casting. |
This person is a regular contributor at teamswift in the FE forum. I haven't talked to him about this though. What's the supposed mechanism that helps FE?
He mentions the grooves helped reduce ping, which he got by going with a shaved head / increased compression ratio. But, isn't taking material out of the combustion chamber simply reducing the compression ratio again? I admit this one's beyond me. |
the idea of the grooves I think is they help to chanal the flame to the outer edges to help with a faster more compleat burn, and altho the groves will help to reduce compression I doubt, unless he bearly touched the head when he shaved it, that those tiny notches have no way of making up that much volume.
