I have a couple of questions if I may please. As far as I understand billet pistons are made from extruded billet bar. Then they go directly to cnc machining. But is there a heat treatment process once the chunk of aluminum cutted of the billet bar prior to machining OR the extruded 2618 billet bar already has been heat treated as a raw material in the form of T4, T6 etc ?
Anyone with a CNC Maching Center and a skilled operator can make a piston blank too suit any type of Engine you can dream of, however there is more too it than that, Piston Material, Shape, tolerance, expansion, application not too mention other factors must be taken into consideration. I don't know what this company charges, but What is being shown here is simular too what I used too do as a toolmaker and from where I come from at $200 aud. an hour making something like this is completely out of reach for the average person.
So if this is machined billet then it should not be as strong as an identical forged piston? Therefore why not either use this machined prototype as a retail piston or reduce the forged version's weight even more?
Forged is stronger like for like, yes, although strength at this level is less of a concern as they're both more than capable of full race usage in an A-Series. It's all about small batches, the experimentation and light weight that allows. We can sell the lightweight specials, but they are approaching three times the price due to the batch size and construction. What we learn from the low volume billet designs go into future development of the retail forgings. :)
2:57 unsprung weight, you say? Nobody could correct him? Exactly why I dislike marketing shenanigans. Mate, talk to an engineer before you write the script. It's reciprocating mass that moves under very high accelerations. Lighter yet stronger means reduced bending stresses on piston crown and reduced tensile stresses on conrod.
Back in early 90s good tuners in Poland fitted only omega for their engines. Godden or jawa omega was a standard.
there's no doubt its a very nice quality piston for high RPM.

Now. If they could make a set with gas ports for the SR20 I would be interested in that.
Very interesting!
When are they being sold?
Anything for the R56 Cooper S?
Which one stronger?
@Matthew Cherrington you can forge the billit
Hi, I need billet hypereutectic pistons, do you have them? I'm aiming for 2000HP
is that all your getting from your 950?
How much are a set of rover 3.5 v8 forged pistons?
If you have too ask, you probably can't afford it.

BTW, I'm not saying he's at fault as writing scripts or engineering is most probably not his job or feild
I thought he said un-spun weight.
He said unspun weight, as in conrod and piston are unspun.
@@G53X0Y0Z0 He said unspun! :D
