But you lowered the compression ratio by engraving the numbers!!! Its pretty silly but as long as it doesn't cause any "hot spot" problems then why not...

Tegheim · 12-20-2011, 04:51 PM

Haha, you didn't like it

I have 0.5mm left to cut, this was just a fun test

My5ABaby · 12-21-2011, 02:55 PM

I think having the compression ratio somewhere on there is an excellent idea. Where you put it is up to you... it's different there, but not bad.

I think it's a great idea, but I'd recommend not doing it on any of the combustion chamber surfaces. The edges of those numbers might become localized hot spots, that could lead to pre-det issues.

BTW, Awesome build!

I'm thinking about making my own centerplates, billet of course. And in steel at first. What are the biggest issues that stock centerplate have?
This is just a thought at the moment...

Could I improve the cooling or something else easy? The front and rear would probobly be stock.

Now finally the production has begun for real ... I had never guessed that it would be so much preparation work on these. Do they look simple, but have been scratching my head once or three times ...
On top of all this, a revision of the CAM program take 5-15minutes of the heaviest pieces.
3st roughing 3D pockets from one direction is about 1500kb large program. Times the third Times two ...
Milling time, we will not even go into. It takes time

Very Impressive.

In all honesty, you coul dmake a killing selling high/low compression rotors to the people in the community. To have the same options as the pistion guys would be beautiful.

It's accually kind of fucked up that we don't have aftermarket-rotors with human prising. The piston-guys could pick and choose how ever they want. I also want that without sell my mother.
