pistons and cylinders

[Speed-Randy]

anybody ever use "Hypereutectic"? opinons, comments good or bad but only if you've used them. I dont care what you heard from your buddies best friends brother-in-laws daughters boyfriend put in his car. I only want to hear if YOU have used them

i have used a set of 96mm keith black hypereutetics in bored type 4 94mm barrels for my waterboxer conversion with good results
i have been told they are ok for non-asperated motors
(and i have a set of 104s for sale 80€)

 manufactured products using this "hyper' process  especially in pistons allows for more silicone content which tends to be of great value with ring usage/less scuffage less  wear and tear as opposed to cast or forged items without this process//has been used by several leading performance manufactureres for some time now with great results across the board. A definite consideration  with ANY high performance application especially with turbo/ nitrous assisted engines. I have personally used these and give them a "thumbs up".
