More Efficiency Billet construction allows aluminum compressor fins to be much thinner than a cast steel alloy wheel, less blade thickness make a greater efficiency range, the more efficient a wheel is the lower the intake temperature. In lower volume turbochargers such as these GT55Rs, choosing a machined wheel reduces the cost per wheel compared to a casting, and allows the turbos to be brought to market rapidly.

For either of these turbos, a cast aluminum wheel using the same dimensions and blade designs would have performed equivalently in most aftermarket applications. In fact, cast compressor wheels are used in the vast majority of the 9 million turbos that are designed, tested and produced each year by Honeywell Turbo Technologies' turbo engineers world-wide.

Billet compressor wheels are available for many popular turbochargers. One place to start is amazon to see what is available for your application. We here at enginebasics. Want to know more about your particular Make and Model vehicle?
