APPLICATION. I guess some don't get it, the application is the answer. All pistons are designed and engineered for different applications. Hypers were designed for street performance engines. Will withstand the heat and abuse of street use. Require less clearance, therefore are quieter. Plus high wear resistance = more street miles.
If a little boost is used, and is still primarily a street engine. Try the 4032 alloy a little more ductile than hyper but a forging.
For racing a 2618 alloy is offered. Hi ductility, requires more clearance because it has a higher expansion rate. These pistons can be machined for your application. Icon now offers an Extreme duty 2618 piston. Which are being run by Jeff Lutz.
