Has anyone tried the NRS Ceramic seals. If so- what did you clearance them at for an over 550 rwhp car, 3 or 3.5 thousanths?
Did you have to mill the housings to get the correct clearance??
Any other info you would like to share....like did you have any hard hot starting problems or anything else.

Thanks,
John

Please PM me if you don't want anyone your opinion kept private.

 

Stock clearances.
No startup issues and the vacuum was 13 inches with a large street port after break in.
Also, there are a few very ruputable people using these seals from this board. Do search. One for example was just recently started by Crispeed where he posted preliminary reults.

PM Glassman (I think) on this forum. He is the guy from NRS that makes these.

 

Thanks. I've spoken to Sven and have done a lot of research, especially on the aussie rotart forums. It looks like I am going to go with them.
