How loud is your turbo spooling??? the reason I ask is, I just got a j-spec motor and it ended up being a rebuilt the tension rods were all numbered and gaskets were brand new....the first few days it didnt do then then one cold night it started and it hasnt stoped. It almost sounds like I have a supercharger. any advise???

 

Well after i got the boost on mine turned up to 12 psi, it sounds like a jet engine at some rpm its pretty loud
