hello i have a 09 challenger srt8 six speed with a procharger supercharger. when it was installed the old coolant bottle that has the radiator cap was removed and a new one installed that came with the kit. aluminum... the new bottle did not rout the overflow hose back into the bottle as the old one did but rather to the floor. when driving under boost sometimes a little coolant runs out of the overflow to the floor not much. it is a irritating problem i asked my friend who is a mechanic and he said i could be losing compression which could be causing the problem i basically told him that was b...s... if i was losing compression it would run like crap and i would get a check engine light. anyway the question is does anyone on this site have this supercharger and did they have this problem and if so how did they fix it... i was going to mount a small overflow bottle somwhere on the car to catch this little excess coolant... also i do not have any air in my coolant system and my radiator cap is fine.
