I would even try it cold first, you can rent a radiator pressurizer tool, pump it up to 13psi and see if you can find leaks

Superchargers that sit on top of engine is known to wear out the gasket on the manifold that it came with in a very short time due to the temperatures under the hood when you r gunnin it all the time. you need to get a hood that lets air n and out the backside to help fix this and I wish someone would make a super duty gasket for supercharged cars roots style blowers instead of having to use a stock gasket

I pressurized mine cold and couldnt find anything. Today I'll be firing her up and letting it get to temps and looking to see where my coolant was coming from. I'll post back later today and try to help you out, maybe you are having the same problem I am. More than likely its manifold gasket
