Porsche is designing super light pistons which are only possible by means of 3D printing. These light pistons will add a claimed 30 horsepower, but how can something a simple as a piston add that much mo' powah babeh? And why does it require 3D printing?

    Laser metal fusion? 🤔🙄i think you mean sls which stands for selective metal sintering.

    The main thing that kills pistons is detonation. Detonation happens because they want to run pistons close to max compression. Detonation damages piston ring grooves and blows holes through the dome. High RPM piston damage is unlikely because friction would be too high at high RPM which limits RPM.

    no. NO. They arent "changing the piston design". WTF is wrong with you? All they are doing is changing the process by which they are made. GOD you're so dumb.

    So the new pistons will start appearing in the last generation of gas powered engines....I think they need to speed up the process. Oh...electric vehicles as a "Green" alternative are now and will remain a SCAM for years to come. All things considered, an electric vehicle involves the creation of more pollution than a gas powered vehicle at this point. Because of all the additional labor required to make a production electric vehicle and all its component parts.

    You should cover spiros panopoulos from Greece..the guy is a genius..he hold a record with his evo witch the motor broke mid run..he has made carbon pistons that actually work...generally he's a genius.and he plans to built the 2nd car that ever came out from Greece and its going to be a mad hypercar..really check him out

    Hello donut media, i just wont to mension that 3D printed brake callipers, pistons and ext. are first to beeing developed and made like 2 years or more in greece by a guy named spyros panopoulos search him on insta and his company on google you will be amazed and you could even make a very intresting video for him.OH and he is making his own hyper car named CHAOS which is a greek word.
