Using a LQ4/9 block with a 4.005(+.003 overbore) 8.7:1 pistons,forged stock length rods,3.8 inch stroker crank(displacement 383 cid), 205 AFR heads,Edelbrock Pro-Flo XT intake,and Ford Motorsports 160 lb injectors which would more easily make 600-700 RWHP twin Gt-45 turbos or a F1-A Procharger?

Why does everbody keep talking about changing pulleys on a daily basis? Put on the smallest pulley you can get for max boost, tune the car for that, and run the **** out of it. We build these cars to go fast not to complain about the 15 minutes it would take to change a pulley. Dam get a big screw driver and a socket and pop that sucker off. A s/c boost controller is my right foot, if i want less boost just short shift the car, the engine will be happy you did.

In my opinion, having to change tunes because you're lowering or raising the boost is too much of a hassle, and can lead to accidentally fu--ing something up. If you have 1000 hp, why not let the right foot dictate how much power to apply for the situation, and leave the boost and the tune constant? Short shifting as TransAmatt99 mentioned works very well.

Different tunes/boost, and being able to WOT throttle shift is the only way to go. No need to short shift, unless the tune is a miss. SC would need different tunes after a crank pulley...boost increase/decrease. Considering the belt stays on...not being a PITA. Just my .2 cents is all. Boost = more power = One hell of a good time either way

I like both but I will most likely always stay with a Procharger since they work well for what I like to do and I suck at fabricating ****. What takes some guys on here a hour or two can take me days sometimes. LOL! I also like my a/c since my car resides in Florida it is a must to have and I always get a kick out of watching peoples face when they find out it has a/c and full interior still.

I know my friends 04 GTO Trex M6 D1SC car that I tuned was a f*cking blast on the street. It ran 9-11lbs of boost which put that 4000lb turd into the 10's @ 127mph. I will let you guys know how I feel about the turbo setup after this spring / summer.

Thanks for posting that graph because it's something I was debating when I started looking at how to get more power. I was looking at all three options, bigger cubes, turbo, or procharger. I'm a six speed and most of the driving I do is 2-lane backroads so I was mostly looking for more power in the 2500-4500 range. At first I was told that bigger cubes was my best option, which I beleived, but talking to some people they said that a procharger even at low to moderate rpms would make good power and the throttle response was instant. Looking at that graph shows that even at 3000 rpm, you have an additional 60+ ft/lbs of torque which only increases as the rpms go up.
I'm going to keep the boost moderate at first since I'm going to be doing the tune, and I'm going to still be on a stock shortblock. Hopefully it'll stay together with 8psi of boost and a conservative tune and I'm also going to add some MeOH as a safety measure.

Read, Read, and Read more.
Nothing is "easier" to tune, whoever tells you different should not be tuning cars. Granted, a lot of factors go into tuning, but generally speaking a sound fuel, air, and spark setup should yeild the same results no matter what the platform, no matter what the setup. My last sentence is meant to be VERY broad...
The reason more people prefer turbos is because they are more efficient, effective, and simply work. Prochargers can be very nice depending on what kind of power you want to make, ease of installation, kit completness, etc. However, turbos can do the same thing with less effort. The kits however will take up more room and are more complex (from a piping sense) to build.
In my honest opinion, superchargers are stupid...Unless you want to go slower than a turbocharged car... If that's what you are looking for buy a Magnuson.

He does have a point. The fastest cars are supercharged, granted they are running nitro methane which is responsible for a large part of the power they produce, but still, if they could go faster with a turbo, I'm sure someone would be running one.

I'm not getting into the debate but the roots style superchargers aren't the most efficient type of forced induction so it's not really a good comparision. I think a better example is the pro mods.
I can think of combinations where a supercharger is superior same with a turbo set up.

The more I read about FI the better Prochargers look.
No disrespect to Turbos guys but I really don't need all the complexity a twin turbo setup entails.
