    How much more boost will I make with a 3.4 pulley rather than the stock pulley on my 98 gtp? I know every car is different but a ballpark would be nice and will it be a definite difference?

    You'll most likely make around 9-10 pounds. You'll notice it.

    You don't want to slap a 3.4 on a stock motor. You could blow it.

    Any more info on your mods? Weather and elevation will play a huge role as well. I see you're in Washington, if you're at high elevation you might get away with a smaller pulley even if you're stock.

    Doesn't sound like the mods required to drop down to a 3.4. You'll end up being slower than stock (unless you're way up in the mountains) and possibly damaging something. Grab some headers and a custom tune and you should be able to use a 3.4.

    colder plugs and thermo arent doing anything at your mod level.
