Is it worth setting up a NOS system for a LS1 sitting at 450 hp naturally aspirated. I have forged internals but as far as tuning, how much would it be? Would I be getting to close to the limit for the aluminum block?

 

I think you posted in the wrong section if you're looking for a "no, don't spray it" answer...There's quite a few guys that are extremely comfortable in pushing the envelope in here. From what you've posted above, I wouldn't hesitate to spray it either.

Okay, I am quite scared of blowing my engine. I don't have the money to fully rebuilt it if all goes wrong, so if it blows I'll be pedaling my bike. But I would really like to get more power.

 

As long as you have a good tune - correct plug and the fueling is good then i wouldn't hesitate to spray the vehicle.
