Supercharge a 4.9???
I have a 1992 Seville STS and I was wondering if anybody out there has supercharged one? I haven't seen any for this type of motor for sale and I was wondering if its even possible? If so where can I get one?

the problem your will find stock PFI engines have too much compression to take advantage of supercharging. Also lack of aftermarket support. 4.9 PFI engines are somewhat common, standard in deVilles from 91-95
