I have a Question for all you 86 celica all track drivers I have a stock motor with a t4 turbo in it. I have the regulator set at 8 psi and the turbo shut off unpluged but i dont want to overload the motor.
It is a racecar so i was going around the track and all of a sudden I watched my boost gauge go up to 17 psi and the car was just flying unfortunatly I melted the blow of valve line.
Is there any other way to get the turbo working harder to an extent that wont ware out the motor to fast.
