    So recently stumbled across this thread. I recently had my motor built and had a stock size ATI damper installed because i thought it was better than the stock balancer. I am running a procharger stage 2 D1SC. So would i assume it would be better to switch back to the stock balancer with the procharger pulley that piggybacks on top of the stock balancer. Car has not been tuned yet so no WOT pulls. Still putting break in miles on the motor. Also the built motor is an MMR 1000 so i'm not planning to make more than 850-900 whp. @ProChargerTECH what do you think?

    I’m running an ATI with no problems and would recommend it over stock. The key is a proper install.

    Yep. People having issues with ati balancer is likely install issue. I've had ati balancer for almost 20k miles. Rev to over 8k. Ati balancers are on everything in motorsports. They are in every nascar car. Think about it.

    Yea I never even knew this was an issue until recently. Perhaps I will have the shop that built my motor double check the install of the balancer just to be safe before I get tuned.

    I'd imagine 99.9% of engine failures attributed to having an ATI on were due to installation error.

    With that being said, I had a lengthy conversation with Ford Performance technicians before ordering my aluminator and was advised the stock aluminator balancer would be fine for my whipple setup spinning to 8,000 rpm.

    And yet FP runs an ATI balancer on their Cobra Jet. Sure it's fine for you but he may have been just trying save you some money and not trying to imply the ATI was a bad balancer.

    ATI balancer requires installer to take measurements of the crank snout, and hone to spec before install. Most people don't do this causing undue stress on the crank snout. Some get away with it, and some loose there crank. It has nothing to due with the quality of ATI balancers really.

    I had my built motor and trans installed at D Mark Performance in Arlington Heights. I have a remote tune from Lund so I will likely be going back there to rent the dyno, assuming he has it fixed by the spring (it's currently down). If not there is another shop in New Lenox called Geared Up Motorsports that I have had work done in the past on my car, and they are also a good shop.
