Is there a way to partially fill in the recesses in teh rotor faces to raise the compression ratio without spending extreme amounts of money? I have gathered some information by searching but couldnt find a definate answer to whether or not it could be done. I know you would have to have something with the same expansion rate as the rotors. someone suggested bolting a plate in there if you were building a drag motor, but i need it to be reliable for a street car. i would like to put some in my na 12A maybe around 11:1 or a little bit higher. so does anyone know of a way to do this that would work or have any ideas of something that might work? thanks.

 

I would see if the ceramic place will when getting them coated. I would only do 10:1p-10.5:1 or you will have a hard time tuning the engine.

 

By the time you made some and got them balanced and all you may be better off buying Renesis rotors and you will be done with it. Of course the 12a idea won't work but I would never put too much time/money in a 12a anyway.

 

I am running a set in my engine now
