The P trim should work fine, but would the Q trim be better? The extra $150 it will cost for the Q trim would not be an issue at all in the grand scheme of things. Now if the P trim would be better than the Q trim it's a different story. I've just always been told that with a ported motor that the Q trim is the type to go with. Just wanting to make sure I get the best of what I need.

^^bump^^



Anyone have an answer to my question from the last post??

I would go with the clipped P trim in a 1.15 housing on a briged 13b. The only reason I would go for the Q trim housing was if it was going on a ported 20b, and you basically can't go over the 1.32 P trim. I seem to remember Crispeed running a 1.32 P trim hot side on his 9.2 second car. Something about the old turbonetics Qtrim wheels comming apart.

I have heard here and there about ceramic turbines. Anyone had experience with those or knows anything? They are suposed to speel really fast and handle heat very well.



PS:

just got my issue of popular science, they made diamonds artificialy. Wait thats that the good part. The good part is they are going to go for 5$ per 2 carats!! At that rate we can afford to make a solid diamond turbo, LOL ^^ you know what they say, diamonds last forever https://www.nopistons.com/forums/pub...#>/biggrin.png

also P trim wheels are cheaper, so when you start chucking peices of apex seals threw them the turbo doesn't cost as much to overhaul...

I 've handed gotta see an update, b/c I had a 2 week unexpected hospital stay, but Igy, how are the twins coming along? Sorry....

they do all that but they do get destroyed if a particle were to hit it and crack it. once you compromise it's structural integrity the wheel will break. unfortunately, on a rotary it's not unlikely to break an apex seal and spit it out the exhaust port. you can just say goodbye to a very expensive turbine wheel.
