Precision News Update: New CEA 66mm Turbine Wheel - 6266 / 6766

ok everyone please refer to the "update" at the end of the first post. We were mistaken. The "CEA" 66mm turbine wheel is not billet machined like the "CEA" compressor wheels. However, it IS made differently than the standard 65 wheel was, and offers many of the same benefits that their billet compressor wheels offer over their cast compressor wheels. For example, in the photos below, pay special attention to the thickness of the blades the the snout. Much like the CEA Compressor wheels, less material is used, thinner blades, thinner snout means less room taken up by metal, more room taken up by air, and a lighter wheel with less mass.

Any idea if it is a different material then their older wheels?
The blade thickness at the root of the blade is there to increase strength and stiffness. I wonder how well these will hold up in low-cycle and high-cycle fatigue load conditions.
Lots of badass turbo technology coming out lately. FWIW, one of the biggest changes between the Mitsubishi TD and TD-H turbine wheel families was blade thickness and they reported a signifigant improvement in turbine efficiency, flow rate, and transient response when reducing blade thickness.
Next up was blade to housing clearances. We need a sacrificial surface on the turbine housing so wheel clearances can be minimized…

I am glad I sold my 6765 that I picked up a few month ago.... I wanted to go with a 6262 but I was feeling the need for a few more ponies and I think this is the Answer. Now if I can just decide if I am going to install my MAP "Top Mount" or Stick with the ETS EL Setup I have on the Car right now.... WHY IS LIFE SO HARD SOMETIMES....
