yeah I think a MP112 would be a bit overkill on a 3400. On a 3800, all it pretty much does is add a bunch of torque, which the 3800 already has plenty of. To give you an idea, by the time you make the decision to go with a MP112, you've probably already done everything else. When I demoded my monte carlo a few years ago, I put all the parts onto a grand prix, along with our prototype intercooler, and with a slipping supercharger pulley hub, the car made something like 350whp and 460ft-lbs at the wheels with 9psi. Now if you add a MP112, how useful is the extra torque going to be when the car already breaks the tires loose at 40-50mph.
