1) New Bob Weight Calculations in Engine Build Log Book  We've made some significant improvements to the way the Engine Build Log Book deals with the Bob Weight calculation.


This is a free update to any one who owns the Engine Build Log Book.  If you own the standard $249 Log Book, it is a $100 upgrade charge to get the Plus Version, which has some of these Bob Weight features and many other advanced features, like:

If you already own this program and want these latest updates, install the latest version directly over the top of your existing version from the link below

  for the download link to update your existing Engine Build Log Book program.  When asked, select to do a Refresh installation instead of a Complete (typical) installation.

  for more info on the Engine Build Log Book program or to purchase the program.

  for info on upgrading your standard Log Book to the Plus Version.


2) New 0.3 CFM Blowby Sensor for Kart Motors  Since kart motors make much less HP than larger motors, they also make much less blowby.  Therefore, we've added a new 0.3 CFM range to our range of blowby meters available.


Blowby is probably the best indicator of how well the rings are sealing, much better than leakdown or compression.  If you already own a blowby sensor and want to have the range changes, send it in and we can do if for $50.  Standard ranges we have now include 0.3, 1, 3, 6, 12 and 18 CFM.  We've also made special custom ranges of 30 CFM and higher for big blower motors.

  for more info on the Blowby Sensor.  We also offer a data logger for recording and displaying blowby readings and RPM if you want if you do not have a logger for the sensor.


3) New 3500 CFM Air Flow Meter for Dyno DataMite  Some of the highest HP our Dyno DataMites will deal with are the tractor pull guys.  And with all this HP comes very high air flow rates.  To measure 3000+ CFM of air flow and to keep the flow restriction of the flow meter low, and to keep the size of the meter low, we developed a special, high range CFM Flow Meter.
