Re: Interesting article about Billet vs. Cast wheels
As far as I have heard, the reason why the billet wheels end to be more efficient is the newer more efficient design of the compressor wheels.
They say they are also easier to be made because cast tooling is expensive, but yet they charge more for the billet wheel. That part I don't understand.
