10% ATI Super Dampener and FI?

Would the 10% under-drive version still work good with a FI setup or would I have to stay with the regular version? Just curious as I'm debating what I want to do.

Sure they work, but not really needed. The couple horse power you might gain from it under driving the accessories is rather moot when dealing with the horse power increase from FI. I switched from an underdrive to a normal one when I did the procharger setup. My AC blew cooler, and my electrical system was happier.

If you have a supercharger it will lower your boost I think, will have to compensate with a smaller pulley.

Turbo, won't matter.

Depends on the supercharger type. Procharger for instance uses a third belt and add on pulley, so it is unaffected by the main drive diameter.

Appreciate the input. I was looking into it based on availability, not so much HP wise.

The ATI Performance Products 10% underdrive balancer typically does not have the three holes drilled through the outer skin, that are required to bolt the ProCharger crank pulley on to. You can take it apart and drill the holes out pretty easily, but I thought I'd mention it. Bob
