LSA Blower on NNBS Pulley Size.
I'm currently running a ported LSA Blower with ported 5.3l Heads and custom BTR cam. I currently have a 2.45 upper Pulley and the truck is making 10 PSI with the stock lower. I want to raise the boost to 15psi. Does anyone know what size lower Pulley I would to achieve these.
Thanks
Thanks

This site has a good pulley combo list:

To technically reach about 15 psi, you'd need something like a 8.60 or 8.70 lower.
You probably wont be seeing 15 psi on your gauge since you have ported blower / heads, but you probably knew that heh, boost is tricky that way
Hopefully that helps! Cheers
