it would take it from a mid to low 14second car to an easy high to mid or even low (with suspension mods) 12 second car. BTW, my procharger is for sale. if you would like more details email me at koby12@ureach.com

I went 12.6 at 111mph,in a totally stock engined 89 Iroc 350.All I had was 3.70 gears,BFG drag radials,Full exhaust,and ignition box.I would recommend upping to 24lbers,if your factory injectors cant handle the extra psi from the fmu,my 22lb injector held up fine,so they stayed.There are a couple of little things to do to keep the motor out of detonation.Run colder plugs,I ran 2 stages colder.Make sure your motor is sealed up pretty well before you consider supercharging it,because that little manifold leak you have now will turn in to a river with the extra crankcase pressure.I ran 3 breathers,if you have a good sealed motor,that will all be in the past if you dont vent the motor,you will blow out all kinds of engines seals.
