Has anyone tried super squish pistons? Options

[Jeff Nelson]

I can't seem to find anyone who has used the squishies in a type 4. There have been numerous type 1 applications. I know that Jake tried them without much success but that sounds like it was a cam related issue.

One big thing that keeps the type 4 from being a modern 2-valve pushrod engine is the chamber design. It would seem that the super squish piston, if it works as advertised, would address that. I'd love to have an engine that runs on 87 octane California gas but reliably makes 1HP per cubic inch in a daily driver.

I know for a fact that Nickies have been paired with John's Super Squishes and they work excellently together. The type 1 engine that Jake built did have lots of torque vs. flat tops with the SS pistons and did have improved BSFC, but he did have some tuning issues with the cam he chose as was previously mentioned. The engine ended up having the SS pistons replaced with flat top mahle's and retained the Nickies and was sold to one of my customers. That said, 1hp per cu/in is attainable, but at what price?
