UHHH Trippy ass rotors? s4 TII? check em out!
Pulled apart some motors this weekend, and found these rotors. s4 TII type -e , came out of my old 10th ae motor..
Im staring at these things and wondering Why the hell they are grainy? The housings were fine, no damage or streaks from the rotors, and its on both rotors. Did they come factory like this? I cant see how both rotors would be damaged, and not the housings, with how the whole rotor is this way? http://i542.photobucket.com/albums/g...7/IMAG0621.jpg http://i542.photobucket.com/albums/g...7/IMAG0619.jpg |
I pulled apart a s5 NA engine and one was smooth and the other was just like your rotors, all grainy.
I think it's normal or part of the machining process???? Idk |
Thats just how the material looks from the factory. Looks like that edge pinched something at some point though.
|
Yea s5 rotors are machined like that, ive seen some variance in a set that were in the same engine, i think they machined them and then balanced them and made the sets, vence the slight difference in some sets
|
its just a machining mark, they needed to change the bit....
|
Yea im just tripped out by it , It came out of a 10th anni, i dont believe it was ever torn apart
|
finishing marks. some rotors are super smooth due to age and use. if you pulled some out of a rebuild they could have hundreds of thousands of miles on them.

strange though, weren't S5 machined and S4 cast? Or was that just the combustion "tub"?
