Thanks guys! You are correct, we have been fondaling Sheltons supercharger while keeping my car running so we can get some ideas on what to do. These are permanent modds, and will not be able to be turned back stock (for the most part) It took 2 samples to get it right, now we are on the right track. I am hooking a boost gauge up, and air fuel to see what pulley I need to buy, and get LET to send me a new tune
I will say this thing sure pulls good, especially on the big end!! I am also playing with my NOS system too. I want to be well into the 10's on street tires!!
