Totally new to the forced induction game and need some advice on what to do. Have an 01 GT with a recently installed ZZP crate engine and Triple Edge HD tranny with a ST1 Cam, 130# Springs, #42 Injectors, Powder Coated Rods, SLP cat back and a Z7 Precision Turbo Kit with FMIC. Car is running well and really can't complain about the power, dyno states 280 HP at the wheels, but bitten by the bug and want more. Running off waste gate spring which is giving me 9 lbs of boost. I think this setup is capable of making more power safely, it's my daily driver, so looking at options of what to do. If I want to jump up to lets say 12 lbs of boost, what's the best way to do that? Replace the WG spring? I have a manual boost controller but just don't get how and where to install it?
I also understand the concept more air, more fuel, more power. Should I also move up to #60 injectors and/or a L36 High Velocity Throttle Body? Considered Northstar TB but heard they are sort of tricky with their response and road manors. If I jump to large injectors and TB, is my fuel economy really going to suffer or will those improvements only really benefit the WOT overall output and not effect the MPG's? Running stock in-tank fuel pump with no issues now, will I need to upgrade that with bigger injectors & TB?
Meth a good or bad option?
I totally understand no matter what I end up doing it will need to be tuned once again.
Like I stated, this is my daily driver and like the current road manors it has now, the wife drives the car and want to keep it easy to drive, if you know what I mean.
Any input and advice is appreciated.
