Squish Band Calculator

Recommended Posts

As per title does anyone know how to calculate squish or have a calculator that can plug some numbers in for me?

 

I've got a strange piston and headgasket combo that I'd just like to play around with before I make a decision

 

Thanks

Thanks Johhny

 

First one doesn't really give squish clearance which is what I'm looking for. A value in mm. Just seems to be a picture at the bottom of the page.

 

Second one looks like it would work though. Does anyone know where I can get the dimensions needed to fill that out? I've got the first 2, head gasket thickness and pin diameter :)

Physically measure it, anything else is risky. You need to understand the implications of how squish affects combustion. A lot depends on combustion chamber shape, piston crown shape and how swirly the inlet ports generate.

 

Okay thanks Chris. I was hoping to find out a rough number so I could then decide whether or not to use some slighlty different pistons that I've picked up. Would have to use a pretty thick headgasket and this combo would probably throw squish figures into a total unknown. So I've no idea whether to ditch the pistons or throw them in over the winter
