Piston to wall clearance supertech pistons
Hey folks. I did quite a bit of searching on this and found some varying info.
Per an earlier post by Savington supertech reccomends a .0028” ptw.
I have gathered that this seems a bit “tight” for a performance build.
Savington goes on to say that he uses a .040” for some of his track cars, and even higher on others. Other forum members have used smaller than reccomended .0028” and that was universally frowned upon. Finally a few guys have run between .0030 and .0040”
i am building an engine for street and occasional track events. It will be NA initially and then will receive a rotrex c94. Goal is a modest 300hp.
Is it safe to say .0035” is a nice happy medium for my intended purposes with the supertech alloy? I would like to keep oil consumption minimal and get some good miles out of this build. Oil squirters will be plugged. Any recommendations would be appreciated.
Thank you.

Alright guys. Thanks. The spec is .0028. But that does not take into account a forced induction build. Sure you can boost on the spec but generally I’ve seen over the years that more power and boost tends to use a little bit loser. I was just trying to determine if there was an accepted middle ground for these pistons and moderate. boost. Thanks for the replies.
