Hi guys and gals, recent lurker and new to the forum here. I bought my 2005 Crossfire SRT-6 a few months ago and have loved it until recently (~58k miles on the odometer).

I had the oil changed and transmission fluid and filter changed. She ran fine for a week or so then I gassed it going up a hill. The supercharger did not engage (felt like I was driving a four banger), and I got up to about 4000 rpm to crest the hill. I then took my foot of the gas, engine rpm dropped to about 1800 rpm, and a big cloud of smoke came from the back. It looked white, but hard to tell at 50 mph in the rearview.

I got her to a local mechanic who had it for a bit. He says it's burning oil and thinks it's the supercharger. No oil in the coolant and no water in the oil, so he doesn't think it's a head gasket. (I'm about 500 miles into the oil change). He didn't want to get into the supercharger work so he sent me on my way. At least he wouldn't charge me for his time. So now I've got her home.

Based on lurking through the threads here, I think the supercharger cut out due to overheating (original intercooler pump still in place) and I have already ordered an intercooler pump (Johnson CM30). I did some of my own testing, and when she's in park and at normal operation temperature I see no smoke from the exhaust (blue or white). Even when I rev the engine to ~4000 rpm. I don't think its worn pistons / rings/ or anything in the engine proper. I had my wife follow me around town under normal driving and she says there is oily smelling smoke during acceleration. It seems to me like I'm only getting smoke when the supercharger is running. I've found a few used superchargers for sale, and am considering swapping it out.

My wife wants me to take it to the dealership for diagnostics, but I wanted to consult here first. So, any thoughts or ideas would be greatly appreciated. Thank you.
