What you'll find on any of the GTO forums is that it basically comes down to maggie or procharger.
Maggie advantages:
-Makes lots of torque down low, so just about anywhere in the rpm range you can stomp on it and get instant response. I produce 400 rwtq @ 2000 rpm, 425 @ 2500, and my full 451 @ 4000.
-Easy to install. I did it by myself over a couple of weekends.
Maggie disadvantages:
-Not as much room to grow. If you want to keep piling on hp and tq, the maggie will top out much sooner than the procharger.
-Torque addiction: You're ALWAYS looking for any excuse to get a fix.
Procharger advantages:
-Makes lots of hp up high. If not for the rev limiter on our engines, you could easily keep the hp gain going as you rev up to ludicrous rpms that our engines could never withstand.
-You can keep pulleying down (as long as your bottom end can take it) to ridiculous levels of hp, (but you'll still top out much sooner than twin turbos, which is another ball game altogether).
Procharger disadvantages:
-Not as much tq down low, but don't be misled: there's still a sh*tload available once the blower spins up, and it's not THAT far behind the maggie.
-Harder to install, but can still be done by one wrench-worthy person in a couple of weekends.
I basically chose the maggie for its instant torque, which is what makes a fun street car, and so far, I haven't regretted it. If I was into 1/4 mile action at the dragstrip, I probably would have gone with a procharger D1SC (not the smaller P1SC).
. Rob Segura said he wasn't sure if the new model 122 Maggy would fit under a stock goat hood but knew the 112 would for sure. Anybody have any insight into this?
