If it is a 2200SL I would just go with an ATI 20% OD balancer and 3.47 pulley to start with. A 100inch belt will work with that setup also.

Isn't that roughly= to a 3.3 pulley? I know jpc said the 20% ati gives about 15% more boost so 3.48= 14 psi + 15%(2.1 psi) would be around 16. On the vortech site it says each pulley size is good for 1-2 psi.

on a stock crank balancer 3.48 is good for 14psi

then a 3.13 will be good for 16psi
and a 2.95 18psi
seeing what pulley should i get for my setup
