Ati balancer

My suggestion is if your RPM range is below 8500, the Fluidamper and the Innovators West dampers are much more effective. Once you get over that 8500ish RPM range then the ATI is more effective.
I will look into that. Are the newer Fluidamper's fixed for pulley alignment? The older ones where spaced out about a 1/4in. Never looked into the innovators west. I don't recall seeing them in summit. I have a trick flow one now but it's not marked every 90* and the paint came off with brake clean. The engine really never sees even 7000rpm.
