ok my goal is a 11.9 in the 1/4 out of my stock 97 saleen conv. which is now my daily driver. only has 29k on it to the engine and body so its perfect. i no im puttin a super charger on it not sure which one yet tho. so my ? is how much power do i need to be puttin down for my goal and which is the best way to obtain my goal. ps i dont want nitrous so dont add that into the mix

Depends on how much boost you run. With a few bolt ons, good tune, 12-14 psi, I think youd hit it.
