the mahle piston made good reliable block ? in long terms this is better than the new inline pro piston ? anyone have tested this piston on F.I in long term ? wazii ?

 

all frm compatible pistons are mahle.. regardless of what the name is.

After a couple of motors came back with melted pistons I cut a set up, since they pushed the ring pack up to keep from having the 3rd oil ring be in the pin boss these things are only 0.060" thick under the intake valve.. thats too thin, that area of the piston gets too hot and causes preignition or just melts.

Thats the main reason we started going with our quickie sleeved blocks and wiseco pistons. Wiseco's are at least 2x as thick there.

 

so its better to sleeve ? even if you looking for only 450whp +-

 

Noooo, same on the ones I bought? Or only on the N/A ones?

 

Has anyone successfully ran these pistons in a high hp turbo engine?

 

the stock sleeves are plenty strong, it doesnt seem that there is a good piston that will work in the stock sleeves. You have to sleeve to run a different piston.

The pistons I cut up were -7cc




The only set of NA pistons I have had fail were mine at ~14:1 compression on pump gas. Since my 2.4 is almost done I'm still going to run the mahles in this motor and just be a little more 'careful" with it.

 

At that power, I wouldn't touch the block.

 

Hate this information but better to know it now before I start the dyno beating. Any chance Mahle will take care of this? Any idea to contact them?

 

This really has me worried. I just picked up my mahle -11cc 87.25 pistons and my k24 crank and inline pro f24 rods. Should I really drop the money and sleeve the block and just run standard forged pistons?

 

Hmmm... Me too, good to know this now, still time to fix it. Mahle should step up and help us out ASAP.
