Evening guys,
I may have found a set of new old stock Mahle forged BnPs, what am I looking for to confirm they are a decent 94mm set? Any distinguishing features to spot?
Cheers. |

Question is, are these any better than the new AA kits and if so are they worth the £300 asking over £180 for AA? |

I've been running the Brazilian-made Mahle 94 mm kit in my street strip Beetle for many years without issue. I have over 200 HP to the wheels and shift at 7800-8000 rpm. No issues with the wrist pin area cracking (like you will sometimes see posted with AA pistons).

Looks genuine. BUT. Beware if the set is produced in 2009 -10 and maybe some of 11. With set from that period I have seen a lot of especially 94 mm cylinders that were up to 4/100 out of round. Not so bad on the other sizes. but worth checking. not much fun in putting an engine together that burns oil and has a lot of blowby because of that.

picture shows that is a 2007 lot, the quality should be excellent. They were genuine Mahle cylinders at that time.

| Cheers guys. Worth 70% more than the AA's? That's the biggy for me... I know people are running the new stuff from AA with good results... |

Correct John.
I was looking for it, but missed that the first time around.

"better", FOR WHAT?
I have personally used Mahle to 28psi boost and 7500 RPMs. I would not use Hypereutectic AAs even to 8psi boost, but that's just me.
Mahle forged are overkill for a majority of applications. IOW, it doesn't make sense to use a $400 P&C set when a $200 set will do just fine most of the time.

Well my current Mahle's have lasted since 1989 when I built this eng, will AA's hold up like that? Currently Im running N/A but as soon as I get the cylinders replaced Im adding fuel injection. After the injection is done I might add a turbo to get back some of what I lost moving to higher altitude unless the injection is enough for me. |

If you are going to turbo I'd definitely go Mahle over AA, but that's me.
