No point using S3 rods, if you're going to that trouble just fit some H section versions. Don't think S3 rods are any stronger anyway
It's the torque you want to worry about really, 300lb/ft is said to be an approx limit
Wazzer whats the H section versions?
Ok what about the bam pistons? I know they forged but to what limit could you push them to?
BAM pistons aren't forged.
H beam is a slightly different conrod design to offset the stress field around the point where the webs join the big and little ends. H beam conrods are more resistant to compression by design compared with counterpart I beam conrods.
What power can they handle? As im sure that the bam pistons are stronger than normal pistons aint they?
Any link to the conrods bud?
All 1.8t handle in the region of 280~300 ft-lb depending upon many things, how smooth the map is etc. Although there are variations in different 1.8t engines the weak point still remains the conrods and even though these vary in manufacturing techniques and specifications they are essentially still the weakest part of the engine and all are prone to failing in that region.
BAM pistons are lower compression than those used in the golf variants i.e. AUM, AUQ, AGU etc. this does not necessarily constitute to being more reliable although it does allow more headroom when running more boost. Having said that, the pistons are not a cause for concern, there are many running in the region of 400+ bhp on standard pistons without issues - albeit in the US.
Did you mean a picture showing the standard conrods? Or did you mean a link to a shop with aftermarket conrods? There are many aftermarket options available, integrated engineering, brute, DM, Scat and THS just to name a few all produce forged conrods for the 1.8t engine.
