Compression Ratio Calculations

These 2.2 Liter Porsche cylinder heads were originally cast in Nov/Dec of 1969.  That's right, 1969!!!  It's quite possible that over the last 40+ years someone has done something that would change the original measurements regarding the CC volume.  The upside... you can easily calculate C/R for the engine build once you have a few key numbers.  A little tinted soapy water, an accurate measuring device, a piece of custom fit plexiglass and voila!!! you have the ability to verify assumptions.  I'd encourage all the homebuilders out there to take the extra time to perform this operation to ensure you have the numbers you expect.  As always, BreitWerks is here to help, give us a call.  321-806-8664
