Static and Dynamic Compression Ratio
(Considers Cam Timing and Rod Ratio)

Click on link:

Cylinder Head Volume (cc)  Cylinder Head Vol (cubic in.)  
Piston Head Volume (cc)  Piston Head Vol (cubic in.)  
Gasket Thickness (in.)  Swept Volume (cubic in.)  
Gasket Bore (in.)  T.D.C. Volume (cubic in.)  
Cylinder Bore Diameter (in.)  Gasket Volume (cubic in.)  
Deck Clearance (in.)Note: Neg. nubmer above deck, Pos. number below deck  Deck Volume (cubic in.)  
Rod Length (in.)   Adjusted Stroke (in.)  
Intake Closing Point (degrees)ABDC @ 0.050 lift plus 15 degrees   DYNAMIC EFFECTIVE COMPRESSION RATIO

I'm hoping that posters will make use of this calculator.,. what compression will I/or do I have, is a question that is asked over and over again on forums.

And then there is this link:

  I hope our younger Gear Heads copy this information. Someday you will be looking for it. Even if you don't build your own engines. Its valuable especially today, with the crappy gas.

That's a good compression ratio calculator, but there's a better (at least for me) alternative in the form of a mobile App. It's available for iOS and Android devices, head over to their website and you'll find the App Store links there as well as other Apps for gearheads and tuners.

The advantage is no need to fire up you Lap or PC, no internet required, 24/7/365, everywhere and lots of engine math no just compression.

Thank you!
