When building or modifying an engine for all-out racing, street/strip performance, trailer towing, or most any application, there are many variables to consider. One critical variable is the Compression Ratio or CR. Compression ratio is the amount of “squeeze” the piston puts on the air fuel ratio before it lights  the fire.  And, more importantly, it is the amount of expansion or “push” these hot, high pressure, combusted gases put on the piston.  The more amount of expansion, the more amount of heat and pressure energy can be extracted from each combustion event.

Top speed racing is very much like drag racing, but just on a very long track.  In drag racing, it is power to weight ratio which typically determines your performance.  However, when the track is very long, and your vehicle spends much more time at high speed, it is power to drag ratio which is more important.  By drag, I mean primarily aerodynamic drag or wind resistance.  In addition to aerodynamic drag, there is rolling resistance from tires, driveline losses, but the higher the speed, the larger the aerodynamic component of overall drag.

Have you ever gone to a track that you haven’t been to in a while and you can’t remember the setup that worked so well last time?  Or, what was that change you made 2 weeks ago that fixed a “push” on corner entry?  Or, exactly when did you go to the stiffer shocks on the front?  If you’re like most racers, you just expect you will remember it.  Or, if your one step better, you right it down somewhere.  But now that piece of paper is lost, or you can’t really make out what your notes mean.
