What are the pro's and con's between these two blowers? From what I see the VMP seems to be the best value, but is the Whipple more efficient? Are there any differences in heat, efficiency, etc? I would like to buy a Gen 2R VMP or a 3.4 Whipple in the near future, so I am just doing my research. My power goals would be 600-650 rwhp.
