Dynamometer Services

R.A.D.C. Racing Specialties offers Dynamometer services and support staff . When properly supported with experience, the Dynamometer can be the most cost effective tool to any racer, saving endless hours of on-track trial and error testing. Perhaps the Dyanamometer's biggest advantage is the base line it will establish for you in the future tuning and testing, regardless of your car's on-board data acuisition capabilities.

CUSTOM PISTON OPERATIONS

Piston Lightening & Results
The end results of piston lightening are many, but caution is advised: this is an area where expertise, experience, a thorough knowledge of forging alloys, forging processes and exact application understandingis required.

     * Reduced reciprocating weight.
     * Reduced Frictional Horsepower Losses.
     * Reduced levels of consumed energy.
     * Increased combustion cycle piston escape velocity.
     * Proper Application balanced skirt area.
     * Reduced cylinder wall and bearing load.
     * Reduction in engine generated harmonics.
     * Significant static horsepower gains.
     * Less mass weight + less reciprocating weight = measurable increases in engine                                 acceleration capabilities, increased connecting rod-crankshaft-bearing-cylinder-wall life.
     * The Bottom Line: Horsepower - Acceleration - Engine Life.

Stage 1 - 101 Match weight balancing to +/- .25 grams.
Stage 2 - 102 Internal skirt milling (w/0 Balancing)
Stage 3 - 103 Internal skirt milling (with match weight balancing)
Stage 4 - 104 Internal Ring land Area Cut (with match weight balancing)
Stage 5 - 105 External Above Pin Hole Bore (with match weight balancing)
Stage 6 - 106 Internal Under Deck Surface Cut (with match weight balancing)
Stage 7 - 107 External Skirt area to Skirt Side Relief Cut (Recommended for Barrel Skirt of BBC)
