got a ? can someone explain to me the point of using a rear ceremic bearing and a steel front... i dont get it. i understand the rear is the load bearing but does the front turn the same or slower? and if it does turn the same then is'nt it slowing down the rear?

What's up KOF!! I believe was more of price point. You see the big jump in the dual-ceramic engine price. Not saying that it won't increase the performance cause I know the dual-ceramic will out perform the 1steel 1ceramic. Either way we're getting some really good power out of these lil engines.
so u saying 1 ceramic and 1 steal out proforms 2 steal bearings, and 2 ceramics out proforms them all is this right, i just dont see how the 1 ceramic and one steal make a differance from 2 steal, if the front steal one does'nt spool up as fast as the rear ceramic then whats the advantage of the rear cermamic the front steal is holding it back? also correct me if im wrong does'nt the front smaller bearing have to make 2 rpm's to the rear 1rpm. so if the front has to spin twice as fast wouldnt u want a ceramic more in the front then the rear? sorry dan im off my meds!!!! lol |
Both bearings are on a solid crankshaft so they will both turn the exact same rpm.

It all depends on how big the balls are compared to where they they orbit. If they turn the same rpmīs and speed then the rear balls must be bigger(because they have a greater distance to travel, due to larger diameter). Bigger(larger diameter balls) means moor mass, and ceramic weight are around 1/4 compared to steel (if I donīt remember it wrong). There for if you only want to run one ceramic the rear makes the most difference when it comes to mass, and mass is what takes time to accelerate. :tire: |
I am aware of that, but he said rpm and the rpm is the same.
Well, if you want to get technical, the rpm of the inner race will be the same as the crank rpm for both bearings but the rpm's of the balls themselves will be different (and different in two different planes) depending on the size of the balls and of the races. |

Yes they turn the same rpmīs, but they could turn at different speed. :)

I meant just that, the inner races are in direct contact with the crank so they turn at the same rpm as the crank. But the speed of balls them selfs will differ upon there diameter in relation to the diameters of the inner/outer races where they are in contact. I didn't want to step on any toes, just wanted to help explain. :) Sorry I didn't do a very good job at it! :) |

We are on the same page, I didn't express my self very well, sorry! :)

No, you were fine. Just wanted to explain that I was aware of that, but that wasn't the question I was answering. :D
I realize that I should have been studying harder in school... :rolleyes: I donīt get the messages through in the right way, I miss some in the translation. :nod: |
2011 Flash .12 motors differences????
Whats is the difference between the Flash .12 PTS & PT? Is it just the PTS having a front ceramic bearings. Thanks in advance.:confused:
|
That and a few hundred rpm!

and the pt under plus? anyone have an answer for my last post on which ceramic rear bearing is better the one with more or less balls.. |
also i been told the new head on the flash makes it run alittle hotter if u have the old flash head better to use it..
