Hey,
I am looking for some serious advice and experience regarding harmonic dampners for the 2.2. I am building a NA 2.2 for the GLH and has everything lightened internally (crank, rods, pistons, flywheel). It was brought to my attention that at high rpms (7000+), because of the reduced weight, a harmonic balancer on the end of the crank will benefit and reduce high rpm vibrations/reverberations, etc. I have an underdrive pulley (quite small compared to stock pulley) and this apparently increases the vibration problem. I am aiming for 200whp and higher RPM's .. (course use) .. what are your thoughts and experience on this?
Thank you for taking the time,
Francis G.
