SC Blades look worn?

[NoRemorse]

I have taken off 2 blowers, and the comparison of the 2 kind of scared me. My blowe looked MUCH more worn on the ends of the blades. I figured it was made taht way to wear in and create tighter tolerances. I was scared after I saw a second blower. My worries have been laid to rest:

To both tighten rotor clearance and reduce friction, one trick Eaton began using with its fifth-generation Roots is to coat each rotor with an abradable powder coating or (APC). During the break-in period, in the first few hundred miles of operation, a small portion of this coating abrades away, leaving the contact areas at the tips of the rotor lobes perfectly matched to each other and able to run extremely close.

I feel soo much better, now you can too!

how many miles were on the two blowers you compared?

The difference in the 2 blowers shouldn't really matter if the abrasion is supposed to occur in only a few hundred miles...

Does one of the cars have a K&N?

Indeed, NR's does. Mine doesn't (and mine is the other one he's seen. Mine's really nice.)

Ive seen em gouged, scratched and rust spots on some kids SS/SC. He's been spraying a 50 shot. I guess the N0² does damage the rotors <or the sulfar?>.

I have a K&N, BUTTTT

I haev seen it off before I had the intake.

It;s just the very tips of the blades are silvery while the rest are flat black.

Our cars are both 06', with similar milage

Have you had to replace the gasket between the sc and the intake?

Nope, why would i? it's reusable, and in great shape

You mean between the s/c and intake manifold, s/c and TB?
