Keith Black 121 pistons

How much BOOST and HORSEPOWER can the KB 121 Dished pistons handle? They are 28cc dished and say they are suitable for blower turbo applications. With 64cc heads they make 8.6 to 1 compression. They are for a 383ci stroker engine with 5.7 full floating rods. Will they handle 10 or 11 lbs of boost? They are hyperutectic. Thanks
