my current setup is on my 82 bronco with a 5.0 engine.has a 270 comps cam with a bd-11a charger and a 76mm mass air system(no bypass valve).
my truck only revs to 4000-4500rpm between shifts even at wot i never goto 5000 rpm. the bust i get at wot is 6 psi. the question that i have is if i go with the 2.5 pulley would this work with my truck application. because i would need the boost to kick in early and not later in the rpms.
