mac pulleys for A 95 gt !!!!!!!!!
 

are they any good and what kind of hp can i expect i can get them for 70 dollars

About the same as March or BBK style pulleys. If you dyno your car before and after, you would probably see a 6 HP gain to the wheels on your max HP but going up the RPMS you could see a max of 9 to 10 HP.

9-10 hp sounds about right, you will see a little bit of a differeance
