I was with a driving coach during a track day and the instructor was worried that he could spell gas when my car was boosting. I have the original Cartech draw through turbo operating at about 6 psi and you can smell gas fumes in the cabin only after you let up on the accelerator and the boost has dropped to below 0. I've always assumed that this was normal but now I'm thinking how are the gas fumes escaping the intake and is it a flammable danger?
