  A
MSD Pulse Width Modulated Water Injection System adds water at
programmable rpm points to tune the exhaust system to get peak
horsepower. Injecting water into the exhaust alters the sonic wave of
the exhaust - fooling the pipe into thinking it's longer. You will
benefit with more performance at low to mid-range rpms - getting you up
to speed faster. Kit includes: PWM Switch, solenoid, fittings, wiring,
tubing and a instruction manual. |
How
does it work? By injecting water into the pipe at low rpm the pipe
cools off and the sound wave slows down by making the pipe act longer,
thus producing better bottom end power. Limiting the water at high rpm
the pipe reaches greater temperatures and the sound wave speeds up
making the pipe act shorter, thus producing increased rpm and top
speed.
