need knowledgeable opinions on forced induction!! i've decided to go with forced induction on my car, and to be quite honest this is the part of modding i know very little about. i tried looking around and i'm pretty well off knowing how they work and what the whole goal is. but between a t76 turbo and a t42 or whatever i have no idea, 6 rib/8 rib? notta. so i was really hoping someone or many many people could help me out and school me a lil. first off, turbo, twin turbo, supercharger? what's best output for the $? most reliable? etc. what kinda psi can a stock internal engine handle on a daily basis? if i changed the internals what should i change them to, and then what psi can i be running? what other components should i change/buy as well? what grind cam would get the best performance on forced induction? rear end gears? torque converter? trans? any advantages/ disadvantages between the different forced induction setups? single intercooler / dual? front mount? etc. any help that anyone could offer would be greatly appreciated. thanks in advance, and sorry about all the lack of knowledge on my end, but i would really appreciate anything new i can learn from some of you veterans.

best thing to learn is just read the threads here.
if you want to know a specific topic search it.
everything depends on your goals and requirements so there is no specific answer. best thing to do is read up. also check out corky bells book "maxium boost" great info for turbos

if your from wauconda,,, look for the 96 maroon stang with a LS1 in it. He works for HPA which is a F-body performance shop off of 12 and bonner. They know their stuff. Also look for a pudgy bastard driving a teal 96 stang with exhuast and cam, he knows practically everyone out there with f-bodies, they call him peanut. I call him fat bastard

Hey Woody, the models you described are turbos, but the 6-rib/8-rib thing is something us Blower guys worry about. Do you have one specific route you want to go? A goal? Both Blower and Turbo have the pluses and minuses.
But do your research first. Especially if you plan to push the stock block. These LS1s weren't designed for boost. So if you want to run on a stock block, better be very sure of what you're trying to do. Most serious boosters will build up their engine to handle boost and that can get expensive. Make no mistakes, FI is fun, big power, and limitless potential. but is in no way cheap. The N/A to FI conversion is not something to be taken lightly. Lot's of work and money goes into it. But man is it off the hook when it runs the way it's supposed to.

yeah i know that peanut guy, and i'm pretty sure i think i know who you're talkin about with the maroon stang. i've been up to hpa a buncha times, they were actually really freakin cool, let me borrow a sawzall & take it home to try and chop off a stripped header bolt. but that was my 99 camaro. yeah i live like 30 seconds from there. but anywho, i don't know which route i want to go positivly yet. i've been reading all the pros & cons for sc and turbo and am slightly leaning towards a twin turbo setup. i know there's also a **** load of other stuff to do to these cars to be able to boost over ~9 psi safely, and i'm not too worried bout that, i got a 97 cavalier and a blazer to sell, plus a crap load of insuance money from the fire, i just wanted to find out what people have gone with and how they would reccomened it to others. thanks for all the feedback guys, i appreciate all the help.

In my opinion Superchargers are easier to tune and generally more reliable, ie less abusive on a block. Even untuned and pushing it, I've had my D1 on for over a year and a half with virtually no down time. Several of my turbo friends experience significant downtime. On the other hand turbos will usually dyno higher at similar boost/cfm numbers due to less parasitic loss. They also have the nice option of dialing in boost at the turn of a ****. Personally I think blowers sound better cause they sound so mean at idle, where as most turbos can only be heard when accelerating. Turbo's have your typical whoosh sounding blow off, where as ATI's flutter a tad bit more. That's all personal taste.
As for twin versus single turbos. I think the major considerations are that twins have more plumbing, which equals more clutter, more weight, and more things that can break. But they will spool faster and give you fatter area under the curve. The single has less routing and will generally incorporate a bigger turbo giving you a higher peak horsepower level.
So as you can see all three methods have their pluses and minues. Hope this helps.

oh yeah, i totally forgot all about that, but this is going to be my daily driver as well. so which one (if there's even a difference) would be more reliable, i hate downtime. also, which complete setup would generally be more streetable? thanks again everyone.

Turbos can change their boost at the turn of a dial. While superchargers power is linear and more predictable, ie no turbo lag. So on the street the blower car is easier to know where your power is gonna be when you downshift and things like that.
But it's kind of a question that's going to get a biased answer. I've tried to be as unbiased as I can, but I chose the blower route, so obviously I think they're better for me.
