M113K engine harmonic balancer CL55AMG
Is the Supercharged M113k prone to internal vibration between 2500-4700 ...
even at idle after 2k rpm you can feel engine distortion in the steering wheel etc ...
I get this engine is performance engine but it seems not be smooth through the powerband !
Motor mounts are new and transmitting mount ..
I can see the harmonic balancer somewhat wobbly at idle but everyone says that's typical ...
Maybe we can design an insulator washer under the motor mount ?
TIA. Looking for feedback ...

My crank pulley exploded around 100k miles- there is rubber between the core of the pulley and outer part that engages the belts.... so, maybe? Also, maybe there's a misfire. ALSO, make sure you put loc-tite on the bottom engine mount bolts once they are reinstalled. I had one fall out after installing new mounts. Luckily i was going slow and heard it fall.
Maybe it needs a general tune up (spark plugs, spark plug wires, air fllter). If this happens only when moving, then tires are probably not balanced.
