I recently slapped an LSA on my 2015 SS and going down from the stock 3.00 upper pulley to a 2.38. Leaving the lower stock. I’m planning on putting her around 14 maybe 15 pounds and am wondering if I need to spend the money on the ADM kit and commit to 8 rib 3 belt etc etc rather then keeping the stock 1 belt 6 rib setup. I want the current setup to work but I also don’t want to blow anything sky high lol. With this pulley combo the blower should only see around 21k rpm so I’m not sure. Apologies for the naiveness in advance. Thanks.
