Just because he has a clutch doesn't mean he has forged internals. 15 psi on a stock b18a1 i've seen make 300whp(running low 12's at 120+mph), 15+ psi on a stock bottom end GSR will put down some power especially in an EG hatch. Not sure how much boost he was running but that civic was hot, shows what you can do with a budget setup.
