yea i was looking at it as far as simplicity of installation. I don't think ill ever go over 250HP on the vert so something like that kit would be nice and the modifications would be minimal. Ditch the clutch fan and get an extra pulley from the junkyard or ebay and mount them back to back and you would have your drive pulley for the supercharger. 40-50hp gain from the site claimed 4-5 psi of boost would be nice and my the looks of it you wouldn't need a intercooler (but i would still have a tiny sidemount ready if it got to hot.)
It also looks a lot like the one offered on the by Thomas Knight on
