In very cold climates, a stock ADU will produce approx. 380hp and 500nm. This is well within the safety factors that Porsche used when they picked the rods for this engine.
Members of this forum have ADU's that produce 620nm and 2.2 bar at 3300rpms with stock turbo and rods. In cold climates, those numbers are even higher. They don't bend the rods, since the spark fire when it is supposed to.
034's 440hp 3071 kit is recommended for standard internals.
On the forum I can think of about 5 documented on here with pictures of bent rods.
I know of others off the forum.
The 3071R turbo does not produce as much torque as an RS2 turbo in the lower rev range it does however produce more BHP.
Do not confuse the 2.

The motorsport community knew about this ages ago, and upgraded the ignition on the single coil engines.1995 RS2 on Alcohol (6.8sec 100-200km/h)

The compression stresses on a rod are dependent on max torque, where in the rev range it is produced has little effect. 3071R will produce more max torque than the K24 7200. Max torque produced at low rpm can lead to pre ignition through detonation (more time for each knock event to happen at low rpms). What we have then is failure due to pre ignition, and not from compressive forces from normal combustionLast edited by EspenW; 26 May 2008, 23:18.1995 RS2 on Alcohol (6.8sec 100-200km/h)
