Make the new RX8 rotor also 7-8 CR, and we have a wonderful rotor for
turbo engine.
Cheers, Petri
Is that a castable alloy? I assume you mean 7-8% Chrome.
Good idea. We can sell them to the RX8 engine people with a lower
compression ratio for turbo charging. The current 10:1 RX8 rotors
are really unsuitable for turbo charging.
My old buddy Herb Adams showed me some SS racing car spindles
he had cast in Silicon Valley CA. They looked real nice.
I think they were the lost wax process.
Maybe we can talk Larry into machining a rotor pattern and
core boxes.

When I did R&D at Howmett Turbine Components Corp the normal super allow
was 78% Nickel, 20% Chrome. It was a very castable alloy. It made high
grade stainless steel look like warm butter. All the hip implants and
such the Doctors call Stainless steel are actually the NiCr alloy. The
same stuff is used for the sighting system in the M1 Abrams. We sold the
ingots for $100 a pound in 1985 and if we did not have the physical
properties correct per ASTM before the customer did their (usually air
melt) casting, we bought them back at $300 per pound. We would not ship
unless the chemistry (x-ray spectrograph) was right.
This gave a whole new meaning to "Investment casting" LOL !!

I just figured out what "CR" meant in Petri's message duh!!
"CR" is Compression Ratio. I thought he was talking about
the alloy.
