Pistons for turbo engine

[fordperson]

Now that I think of it I might as well try to get Mahle pistons, does anyone know where is a place that sells em retail? (most of the places on their websites sell only larger quanities)

"BMW Motorsport are using Mahle Motorsport pistons in their racing engines (like their F1 engine), just like the VW-Audi Group (Le Mans, GT, WRC), Ferrari, Toyota, Renault, Peugeot and Citroen are."

There is 3 company's that stamp piston blanks and Mahle isn't one on them. Mahle only machines them. Each of the above car mfg's has Mahle machine the piston's to there specs. as they do other companys. BMW is using Mahle pistons as well as other mfg. pistons in there engines.

"With turbocharged engines there is usually a need for hard anodized ring grooves."

With turbocharged engines it much better to alloy "TIBOR" with lead free, no copper in the aluminum than it is to anodize the aluminum.

As for who uses what depends on who cuts the best deal. I'd say I run Coke Cola in my car if they payed me enough.
I'd also piss on a spark plug if it cut 1/10 off my times.

Like usually you don't have a clue what you talk about!

Mahle Motorsport machine their racing pistons in Fellbach outside Stuttgart in Germany. Forgings are produced elsewhere within the Mahle group.

There are different materials used in "racing" pistons, ranging from RR58 to high silicone alloys. Some are also made in an anuminum matrix composite with up to 30% SiC or AlBe, those are however not forged.
Anodized ring lands will introduce a higher hardness/surface strength in all aluminum pistons.

I could care less where Mahle pistons are machined, and I'll tell you for fact, Mahle does not have a forging plant within the Mahle group. We (I) use to forge the blanks for Mahle before we sold out to Alcoa Aluminum.
As I have a Master degree in Metallurgy I'll tell you point blank, you have no idea what makes up the chemistry of the aluminum for pistons.
I'm also well aware what anodizing does to aluminum.
Being your so up to date with metallurgy what is tibor?
Why is vacuum investment casting as good as some types of forgings?
Why are forged aluminum parts heat treated after forging?
