Underdrive damper? I'm looking at getting rid of my underdrive setup that is on there now, the ugly piggybacked mess! So my question is are there any underdriver dampers then?
Looking at Summit I see there are five ATI options listed for LT1's, now if that isn't confusing I don't know what is. Is it worth getting their crank hub, or just get the damper? Is the factory diameter 7.5 so the 6.78 would be underdriven?
I see the ASP one, is that supposed to be run one piece then, it doesn't piggyback? Any issues with it?
Should I go with an ATI, or will an ASP satisfy my needs? It is currently and probably will stay a hotcam motor, so not sure if I really need an ATI?
HELP!
For those who say about charging, well I've had the underdrive pulley on the car for years, without changing out the alternator pulley. I've never had a charging problem.

Good to know you would want their hub also, you would think they would recommend that in the product description or something.
Thanks for the input. I know you race your car all the time Alan, I suppose that should be enough testament to the ASP.
I was really trying to figure out if the ATI was worth the $200+ premium over the ASP for the purpose I wanted to use it for, looks like I'll probably go with the ASP then.
Right now I have I have no idea, maybe the BBK with the stock damper on the front of it, looks hideous.
Parts ordering will commence in a few hours probably. I suppose if there is no huge negative against the ASP that will be the route I take.

Im running the ATI on mine.....I did it just to drop the belt speed I kept frying alternators once a month lol........I'm running the aluminum balancer and hub its amazing the whole setup weighs in just around 5lbs......for spinning weight thats HUGEE!!!! every little bit helps......the ATI is a bit pricy but I'd highly reccomend it......its a perfectly machined and engineered piece and the removable balancer from the hub is nice........also its SFI approved.....my vote is with ATI!!
