not bad at all… puts it right about on track for 320hp
270hp and 290tq = 320hp :nuts:
EDIT- 15% drivetrain loss does mean 320hp :finger:
271rwhp/.85 (15% drivetrain loss) = 322bhp 
not bad since they were rated at 300bhp.
says they had mufflers on it, so i dont really know how much stooopid mufflers might add :dunno:
