Dyno testing is usually thought of as only for engines, but dynomometers can come in all shapes and sizes and be used to evaluate performance automotive equipment across the board. From measuring shock valving in terms of compression and rebound, to torture testing engines on Spintron machines, to even testing power adders; dyno testing has a place in nearly all motorsport systems. Dyno testing surely isn’t the same as getting out into the world for R&D, but before most products get the final sign-off to go compete they are put through a battery of scientific tests.
Superchargers, like those offered by Whipple, and all engine components for that matter are subject to huge amounts of abuse when it comes to thrashing a car around the race track, or just the daily grind of commuting and stop and go traffic. It’s no wonder Whipple Superchargers are used on GM for OEM applications like the new COPO Camaro.
Here we see the 2.9-liter W175ax twin-screw supercharger being put through its paces for a grueling 48 hour durability test. This supercharger is designed for the 2010-15 Camaro, boasts 99-percent volumetric efficiency, and according to Whipple, only consumes one horsepower at cruising power demands to maximize fuel-efficiency.
Just like any other part of an engine, superchargers can generate a lot of heat. Spinning at screaming RPMs and compressing air generate a lot of thermal energy. With heat being a universal enemy of engines, keeping this energy in check is key to promoting durability and a long life span. During the test, an infrared thermometer is used to check temperatures across different speeds.
