super on my turbo

have a 1991 Saab 9000 turbo, now im not looking to go to the track and blow away the compition but i am a little sick with the great deal of turbo lag so i have fabricated a low psi super charger which i intend to install in addition to my turbo charger i want some opinions on this venture by my calculations the small super i made should add about 2-4 psi thrue the entire range. thanx ~PhatPat~

what kind of supercharger have you fabricated a centrifugal or a roots type???? Got ne pics??? this sounds pretty interesting to me.

centrifugal sry no pics im in the process of fabricating the bracket and tubing it has to be piped in behind the MAFS or it will run lean (what a pain).
i used the compressor from a 9000 turbo mecheaned the exaust turbine down to shaft size and welded on a pulley just to give u some idea.
