All BluePrint prototype and production racing engines are balanced to +/- 2 grams in order to achieve optimal performance and life with minimal vibration, even under racing conditions. Balancing and dyno testing are standard on all of BluePrint's street performance engines.

Performance specialist John Nickel puts the finishing touches on a prototype engine in preparation for break-in and dyno testing. Circle track engines are supplied with left-turn valve covers and oil pan, and incorporate other secrets that have been learned over many years of supplying all types of circle track engines.

All BluePrint race engines are run-in for a minimum of 30 minutes in order to allow rings to seat, bearings to bed in, and to break in the cam and other internal components. During this break-in period dyno specialist Chris Larson carefully monitors oil pressure and temperature, EGT's, fuel flow, coolant temperature, and other data points. Initial ignition timing and carburetor adjustments are made. All dyno testing is done with race fuel for circle track engines so that dyno results best represent what the customer can expect in the field, and all key specs and settings are included in the dyno sheets that accompany every BluePrint performance engine.

BluePrint's DTS dyno's have proved to be very reliable and repeatable, providing consistent results pull after pull. Typically pre-production prototype engines see no fewer than three pulls after break-in, with results logged into a database for on-going reference.

After final dyno testing we learned that we had indeed achieved the horsepower and torque goals we originally targeted.
