So I have a set of beautiful and new Mahle 4032 pistons for my project. They are the powerpak pistons with the big piston pin size ( .945") and the Mahle coatings and so on.

I called Mahle and they said the pistons are good to 15psi boost.

What do you guys think? I have heard stories of 4032 pistons breaking in supercharged applications. I would like to be somewhere around 10 lbs of boost for my engine.

Basically I need to know if I should sell these, or if I can use them as they are.

Here is a link to the pistons I have: http://www.us.mahle.com/media/motorsports/hemi-6-4l-web.jpg

Yes, I'd use a good boost controller like AEM.


Truth has no agenda, but those with an agenda make their own truth.
Some of us are so open minded they only see their View

A lot of factors really but people run near 10 on stock pistons, so if tuned properly, should be fine.
