Hello-

A cast cylinder is actually stronger than a billet cylinder, talk to a proffesional metalurgist

False.

That statement is impossible to make, as you haven't specified _which_ casting alloy (three-digit number) and _which_ forging alloy (four-digit number) you are talking about.

I won't tell you the exact alloy we use in our Nickies, but I will say that after extrusion, the tensile yield is over 400MPa. Additionally, the alloy is pretty ductile and has a relatively high impact resistance.

Porsche used an alloy with a decent amount of silicon in it for their cylinders. All of these have lower strengths than our material. Plus, these alloys tend to be more brittle and less impact resistant, making detonation _much_ more of a potential disaster.

Joe, I ask that you do a little more research before making strong accusions like that. Thank you.
