I figured I would write this up so you guys can have a good idea of what you are getting yourselves into before you begin posting your questions.
The most common question asked is how much boost can I run on my stock engine? The answer, is really none. The stock ls1/lt1 blocks were not designed to be running boost whatsoever. That being said (and ignored), you can get away with running boost for a loooong time if you are careful and take the necessary precautions. For LT1/4 motors, the safest amount of boost I would recommend (turbo or S/C) is 6psi maximum. For LS1s, I would say you could run 8psi safely. Some people may tell you that running higher than what I recommend is ok, but remember, the motor will blow eventually regardless of how much boost is run and the more boost, the sooner it goes.
"My motor has X miles, should I buy a supercharger/turbocharger?" This one depends on the actual mileage and what you are looking to achieve with your car. If your are near the 100k mark, I would say not to bother with FI at this point in time. Not to say that it is impossible, but I seriously doubt your motor will make it to 150k miles with FI. If your motor has a lower amount of miles, you could run FI if you choose. But keep in mind, once it is on, you just started a time clock for your motor's life.
If you really want to run boost and are serious about it, there is no other way to go besides a forged motor. Having forged internals is essential to running high PSI in boost and you will have difficulty blowing the motor as easily as it is done with stock internals. Rotating assemblies can be bought on the web for decent pricing. In the past, I have always recommended dyno-flow but I think they have gone out of buisness which puts AMS racing at the top of the list. With a forged setup, your motor will easily take up to 12psi without wincing. Not to mention that you could spray a good size shot of nitrous on top of that and it will help as a cooling agent for the motor.
Should you choose to run FI on your stock (or forged) motor, it is strongly recommended to buy a Boost Timing Module. It allows you to pull a few degrees of timing out to make up for the advanced timing your S/C will add. MSD makes, in my opinion, the best BTM system on the market. You can pull up to 3 degrees of timing out from a control knob that can be mounted into your car wherever you like it (I always put it right in front of the shifter). These units will prolong your motor's life and help prevent detonation.
Hope this is helpful to all who are interested in the world of forced induction.
