Default 997 Turbo on the road again
Hi all
April this year I blew up my engine on the German AutoBahn.
The repair was done by myself except machining activities
Begin this week I made my first testdrive.
The pics starts with a parking place near the Autobahn and finishes with the repaired engine build-in


dismantling







Rebuild

difficult to say but probable root cause is a broken connecting -rod bolt

Nice pics. Haven’t seen a mezger blown up like that before. Too much boost/ torque? Assuming it was not stock?

Maybe too much boost/tq at the low/mid range?

The mods are:
exhaust
intercoolers
DME mapping
other turbo's (don't know what turbo pressure)
fuel pressure
air filter.

It is not said that they caused the failure
