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?

If all you wanna do is outrun cobras you won't have to work very hard

Couldn't of said it better. Pick a HP goal or some other goal to reach, then build for that purpose. 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?

Call a sponsor like Texas Speed or Thunder Racing. Texas Speed has their PRC 2.5 heads and the Torquer v2 cam which will give you nice results and be very streetable. Greatest part it, its only $1999 for the package minus gaskets, etc.

As far as boost- search for a while on this site. There are hundreds of threads regarding boost level, combinations, etc.

Good luck
