Supercharge Or Turbo?

Small turbo on a 6 = no lag. get yourself a turbo that seems to be 25% too small. Itll be at full boost at about 3000 and will start spooling right at about off cruise RPM. The wastegate will let you go as high in RPM as you want while still pushing max boost but how high do you want to wind a long stroke leaner? Myth about bottling up the exhaust gas robs power is a little misleading, as the turbo is producing boost at a level higher than the exhaust gas back pressure. the boost PSI is actually pushing down on the pistons with greater force than the loss the exhaust gas is causing trying to keep the pistons down. It is not a loss, it is a net gain on the intake side. With that out the window, turbos really are using free "lost" power. Do you want instant power off idle with a supercharger (really, how much boost are you getting right off idle?) or do you want gobs of torque slightly into your power band? Sure that turbo minivan is going to get jumped off the line by that camaro, but look who is pulling away at 1/8th. and the turbo needs nothing and does nothing at normal cruise so no wasted fuel. Its how you build it. Turbo a 6 and still get 25mpg. And dont run a roots style blower if your running injectors unless the thing is made to run "dry" many use the top mounted carb A/F mixture to lube the seals. My humble vote is for turbo, do what you can.
