I like the Kumhos ecsta supras, really sticky, 275s look better because they are WIDER.
BTW I found a new supercharger manufacturer on imboc the other day. Called wynjammer superchargers. They advertise about 6psi and about 60-100hp increase. These superchargers are oil-less, no oil pan tapping or changing the oil in the supercharger! Ceramic bearings or something. Plus 3year warranty on supercharger.
Here is the kicker, I heard the whole kit including fuel pump injectors etc was under $3000. Check it out If I had the money, this would be my kit.
