Finally got the JE forged pistons!...As always heres a few pics to keep those who are interested in the loop....


The copper colour is a ceramic coating...




Here you can see the moly coat,thicker oil ring,contact reduction grooves and accumulator grooves(dont ask me accumulator grooves do...somthing about total combustion of the mixture)




From the bottom you can see the different structure against OEM....the JE piston is around 30g lighter than the benz item,which does equate to a decent loss in reciprocating force!




Pistons are off to the engine builders tomorrow..hopfully will get the engine back and in by next weekend!



Interesting coversation for today:
-I met a guy who sevices MB and races a 5.6L 500SEC..he believed "the OEM high pressure cast piston i had would be good for upto 400hp"

-My OEM ECU is not tunable in any way...well i guess thats confirmed!

-My engine balancer was disapointed i had the rods shot peened because he believes the big ends will be warped which will require machining and thus another ballance....

quote for today:
good advise may not always be good advise!
