another boosted slant : D opinons plz

it wont spin past 5000 rpm itll be a daily driver not a racer. im shooting to put about 800 bucks into it. my goal is probably around 250-300 horse. my main concern is whether my 9.5 compression goal with 5-12 pounds of boost will be safe with out detonation problems. ill be running an intercooler so thatll help alot but idk if itll be enough
