im building a 81.5 mm ls vtec and the crank pulley i have has a chip in it and i know that would be bad for the harmonics of the motor so i was looking into a cheaper option then the ati or the fluiddamper and came across this damper on ebay and was wondering what you all think??

interesting i would also like some input on this item as i am in the market for a damper was gonna go ati but after seeing this i might have to try it out

 

I think the ATI units are a little better.

If someone has one of these Pro Dampers I can check the balance on it using a state of the art Sunnen balancing machine

 

i know the ati should be a little better i was just wondering if this was a better alternative then stock but not as good as say a fluid damper or ati

 

 

wonder if it has to be pressed on and off like the ati or fluidamper???? and wonder what the weight is on it compared to the other two

 

is that the one from professional products? had bad experiences with those. bolts backing out, no timing marks, etc...
