Here are links to a couple of sound clips of a iron headed drag race Y engine making in excess of 500 HP through the mufflers. Turn up your speakers and enjoy. You might want to pull your feet back away from the speakers though. 500+ Horsepower dyno pull 1 500+ Horsepower dyno pull 3 Thanks go to Jim for recording these on his I-Pod while visiting.

Unibodyguy (8/19/2010) So Jim what kind of RPM's were you doing with that motor??If asking about the sound clip, the engine is at 7200 rpms before bringing the throttle back to idle.
