You broke a set of rostens right ? So you're running I beams ?? Are those the cuttingham onesI'd say it depends on how much torque that you put through the engine.If you plan on running a big or large single then the factory rods might be ok.
If running compounds then mabye consider a rod upgrade.
My old ALH based engine years ago broke 3 out of 4 H-beam rods.
I now use aftermarket I-beam rods with a 3/8" rod bolt.
The funny part was that I had the BEW rods in my old ALH and decided to upgrade to the H-beam rods as I was worried about the BEW rods failing.
It might be possible that the PD rod would take all the power/rpm I could make with only mabye upgrading the rod bolts,who knows ?
I think im gonna go for a i beam designYeah,Cunningham I-beam.They are a heavy rod in comparison to the H beam but that doesn't seem to matter at all.
Nothing available that i know of that is why im considering the effort/risk of making themArent rods available yet for the 3.0 engine ? I see you are custom making them.
Were your rods from Cunningham forged machined or billet machined ? I know they do either orYeah,Cunningham I-beam.They are a heavy rod in comparison to the H beam but that doesn't seem to matter at all.
Thanks for the link - Post 42 is the one I was thinking of, however the whole thread is worth a read for context

I already have upgraded arp2000 bolts for the stock rods
They're the same ones used in the older two liter tfsi m8x50Where did you get bolts from?
If you are interested in them I might sell them cuz I might upgrade to M9 they have never even been torqued
Are they arp2000?Actually I might. I ordered 2.7biturbo bolts but they are bit beefier. I think they are m9 even etka says m8.5. Wanna change? Haha. To me they are useless anyways.
