( Quoted from Wade at BOP)
2. The crank will NOT be cross drilled. It will incorporate the latest technology in crank oiling, scoop oil holes and straight shot oil timing. This process pressurizes at the low pressure part of the stroke and traps the oil wedge during the high pressure part of the stroke. Cross drilling forces the oil pressure to try and overcome combustion pressure of 1000 plus psi which and translate to 10,000 psi at the bearing. This force will push the oil right back out the journal and send it to another place in the crank. Straight shot traps the oil and it has no where to go but to the rod bearing. It is the best oiling system currently available for low or high HP motors at this time.)

Bob C, That is consistent with the response I got from Mark at Norwalk. We definitely need the high speed oiling system as opposed to the factory style oiling system.
David Reher's article from National Dragster provides some interesting information on why cross-drilled cranks shouldn't be used. Check it out at:
