H/C vs. F/I

hey can you guys tell me the pros and cons of doing H/C vs. S/C for a daily driver? how much boost can a stock ls1 A4 handle? with bolt ons and the blower how much rwhp would it be putting down?

yeah please guys drop some knowledge. i dont know much at all bout F/I. im still new to all this stuff. i wanna be able to pull on pullied cobras.. so im wondering would i be better off all bolt ons and a supercharger, or an agressive h/c setup that may or may not pull on them and lose drivability.. will the internals and tranny hold up on bout 6-8 lbs of boost?

It's a lot easier to say I want xxx rwhp and build to that than to guess and throw money around foolishly. Also decide what the car is being built for: street, strip, etc. You can get 450 rwhp H/C, 550 rwhp D1sc/bolt ons/cam, 750 rwhp H/C/d1sc. All depends on what you want and how deep your pockets are.

Hope this helped

thanks guys. well, my car definitely is a street car. it will never see the track. i was hoping for putting down atleast 415-420 rwhp on an auto setup. my initial plan was to go with mti 2e/x1 setup with all the bolt ons. but if i were to do h/c and f/i it would take me a while. im definitely gonna do h/c first. any suggestions? if i do go f/i how much boost to be safe and not kill the motor? how is vortech superchargers for our ls1?
