If the engine is built strong enough to hold up to it then it will be awsome.. if not u'll probly be takin the bus for a while... My buddy is runnin High Compression & High boost on his Neon & it's at like 10.7 - 11.3 on an average.. but he totaly built the engine.. & went by Mopar Tested spec's or somethin.. all i kno is his shit blows mine away at the track!
