maybe iam thinking conventionally, looking at the function of dat balancer shaft, it balances the dynamic circular movement of the crankshaft assembly, to avoid resonance and vibration dat wud also rob power. so, when u remove dis, imo u need to fully balance the whole internal assembly, which will add more to the cost, which is y i said not worth the trouble and cost, since u can spend dat amount of money on sumthing else dat can provide more power ie turbo, management. i dunno if the tuner posted in dis thread rebalance the engine dynamically but from my pov, u need to perform dat especially if u wanna make power in the higher end of the revv. at least dats my opinion, like i said ive never seen the need to perform dis. the best dat i can think of is to lighten the shaft and rebalance the whole assembly.
maybe i got the wrong idea on the true function of the balancer shaft?
