Hammer brings up some very good points. I wish I had built the motor before we added all of these upgrades. We feel we can get more power out of the stock 4.6 then most because detonation will not be a problem with an Aeromotive fuel system and tuned DFI. Eventually, I will put in a built motor to really see what this turbo can do. With a very safe tune on a crappy day at Atco, we made 388 rwhp & 427 rwtq with just under 6 psi through my auto and 3,000 stall converter so you can see the potential. I can't wait until the end of this week because it should be done. We ran into a problem with the MSD because we need an EDIS-8 module & 12 pin connector, but that is another story. Definately go the turbo route because the car drives like stock not in boost due to no parasitic loss and hits like NOS when full boost arrives.
