Have any of you seen or know anything about this mod? Sorry bout the large pic as I am linking to their site directly.
Forced Induction Crankshafts
A patent pending modification for all two stroke applications!
Dirt Bikes, Snowmobiles, Personal Watercraft, ATV's, Chainsaws, and more!
The Parris Racing Concepts forced induction crankshaft modification works by cutting veins into the crank halves of the crankshaft. The veins are cut at specific angles into one crank half, and then a mirror image is cut into the other crank half. As the crankshaft spins, these veins pick up the Air/fuel/oil mixture inside the crankcase. A process called flow dynamics then routes the Air/fuel/oil mixture down the veins where it is directed at the transfer ports of the crankcase. When the engine enters its intake stroke, the extra Air/fuel/oil mixture is pulled into the cylinder. The flow dynamics affect also atomizes the Air/fuel/oil mixture in a way that it allows a cleaner, more complete burn inside the combustion chamber.
The PRC forced induction crankshaft modification will work on any two stroke engine, i.e.; snowmobiles, dirt bikes, quads, jet skis, and even chainsaws. We modified a 2008 Suzuki RM250. It was found to gain 15.74% percent in HP and 18% in torque. Below is a comparative dyno showing the stock vs. mod results. The PRC modification produces enough torque that it has broadened the power band dramatically. A motor with a PRC, Inc. forced induction crankshaft pulls as hard most of the way through the RPM range as a stock motor does in the peak of it's power band. Therefore, the modified machine gets to top speed faster than any stock machine currently available.
PRC offers repairs and modifications by our experienced mechanics
We Port and Polish!
Benefits of the PRC, Inc. Modification:
Engine Durability - We had over 250 hours on a modified KX250 without a rebuild of any kind!
Power Gains - Increased HP and Torque
Weight Reduction - A lighter crankshaft creates a better power to weight ratio
Machined Precision - All machining is performed on a HAAS 5-axis CNC Mill
Bonus Services - We true every crankshaft free of charge after modification
how much airflow can a 5000rpm wheel at that size with just some grooving make? a turbo spins at 150,000 rpm with blades and a specially designed housing. If nothing else I think turboing a crank will cause additional turbulance, that area already had air flowin gin like 8 directions, why add more.

i would have to see dyno sheets from an independent tester to believe it. at first i thought it was a crank mod for a forced induction motor, not a "supercharger"

Natural selection favors Smart people, so nature selects morons to be slow and dumb for tigers and stuff too eat. But in our modern world there just aren't enough tigers.
