Hey guys, I am in the process of building a LQ4 408 forged stroker and I have a Nitrous Express direct port kit that I am installing into a Holley high rise intake. It has stock LS3 heads with better springs and a custom comp cam. It will also have a dedicated fuel system for the nitrous. Assuming the rest of the drive line can take it, How much nitrous should this motor be able to take? 200hp, 300hp, 400hp, MORE!?

 

Really... nobody?

 

I think that will be hard to answer for anyone but the person building the engine. With a well built motor, good gas, and good tune I don't see why it couldn't do 400 on a direct port. People have certainly done that much before.

 

Cool thanks. Thats what I was hoping to hear. Not so much what my exact motor would handle but how much others have been pushing. I should have asked it differently.
