Cross posting here, maybe someone else is running an ATI damper. Did not get a response in the NA forum.

I got around to installing my super damper on my engine, once it was pressed all the way on I could see the crank key isn't large enough to completely fill the entire keyway. It went on smoothly without much fighting.

Will this be a problem? I imagine it will be fine since its a press-fit but wanted an opinion.

I don't feel any increased vibration or see any wobble but I only took it for a short test drive. I'm hoping this will be some insurance against a blown oil pump.

Thanks
