[VADER SS L99]

[QUOTE=10aSSee D;2940321]All the PD blowers are going to have close to the same horsepower and torque granted they are running the same boost. This statement is 100% not true and if it was we would all just buy whatever blower is the cheapest. A bigger or more effecient blower makes more power per lb of boost because of many reasons. 1 is the blower is turning at a lower RPM. A blower that turns slower doesnt generate as much heat thus decreasing IAT's creating more power through tuning. 2 The bigger blower is moving more air. More air means more power potential. All of these aspects are if the cooling systems are equal and If the cooling system is better and more effecient than another then it too will make more power. Then there is the debate of roots TVS vs twin screw. I will not get into that one but it is of my opinion that a twin screw blower is more effecient than a roots and as a result make more power per lb of boost. If all superchargers and turbos were equal and made the same hp per lb of boost then there would be no market for them and we would not have such a hard time choosing 1.

Anyone who is still a skeptical noob can just do a search and you will find mounds of data on this issue. KB for instance makes bigger more effecient blowers constantly and test them against their old ones which reveal that the bigger blower is making more power per lb of boost. Case in point closer to home is in GMHTP MAY 11 issue. Redline Motorsports added a KB 2.8 to a 10 SS. Its pre KB combination was a Magnuson powered and built LS3 7.0 producing 14-15psi and it made 712RWHP. After bolting the KB on and getting the boost to the same psi it pumped out 796RWHP and 750lbs tq. Are you going to see 84RWHP difference between the TVS 2300 and KB 2.8 or Whipple 2.9 at the same boost level on a stock motor? no, but 40+RWHP is totally possible.
