I have the 3.4" pulley on it. I use an auto tensioner with a larger pulley on the tensioner to keep tension. The aftercooler and ASP header I'm sure reduces my psi output. I have a T1 intake temp sensor in runner #1 of the supercharger and highest temp I see during a 3rd gear pull is 115F.
The reason for the snout snapping it looks like it was built shitty the metal was brittle and they had machined a step in the shaft and it snapped there Scuffers looks way better.
I know alot of the clubrsx guys are 13-15 psi on k24 crank and 3.0 pulley but I think that is asking for trouble on the a3.
