I know. Only comparing to something that may have similarities in weight/speed and thinking gains would be in higher rpms.

So there is a power gain & performance gain to be had.
As for the light weight blower rotors....
I'm not too keen on them not applying an abratable coating. The coating provides tighter tolerances and helps with efficiency.
The abratable coating was one of the advancements Eaton made to their blowers as they went through different generation changes.

Hey Guys! I emailed Stiegemeier. And here is what they said, "We are working on it please contact us within the next month." We gonna have to wait next month and find out. Can't wait!
This is prob one of the best setups I could see happening for the m62.. releiveing rotational mass by quite a bit making it easier for revvs and free up some cooler air... There is a lot of potential .. but It does need the coating for reliability of less heat soak and ect.
Correct, but replacing the stock shafts with neutral balance shafts will free up about 10hp or so.

I hope they end up putting the coating though, if they dont you'd likely see a loss of boost with them compared to stock. Especially for anyone running over 15psi.
How? Neutrals are heavier than the stock ones. They're really just there for people who arent man enough to do the delete.

What I have stated has been told to me by a GM Engineer as well.
and no in most cases neutrals are lighter than the stock shafts.
I was speaking of the ZZP lightweight neutrals fwiw. I didn't think anyone used the GM shafts since they are heavier than stock.

$300 seems reasonable for the lighter rotors, but its not like they are just drilling holes in them and calling it good. Seems like a fair amount of time would be tied up in this job... Test, disassemble, machine, balance, assemble, test, possibly parts, oil and shipping. I see it being over $400.
