Will upgrading heads increase or decrease turbo spool times?

Anytime you increase the flow of air through an engine ( another words reduce pumping losses) Your turbo will spool faster.
Note head HP increases ar hard to figure because you have flow numbers and compression numbers. 100HP gain ??????
Note Turbo cams are usually low in duration high in lift and around 112* LS. :hick:
