i have a quastion How Many Hp Can you Get From N/A LS1 without Superchargers and Turbos NA build up my Guess is About 400whp is possible What You Guys Think ?

[Mr. Luos]

400 RWHP is easy. I am at 380 right now on stock heads and stock tune. A nice tune alone would kick me to about 400.

Somewhat streetable, I would say 450 RWHP is obtainable. Bigger cam, good stage 2.5 heads, ALL the bolt-ons. Costs quite a bit of money though. Supercharger would put you to over 500 with a couple bolt-ons. And for less than a complete valvetrain build.

Track only LS1 cars have seen damn near 500. I think a select few M6 cars have gotten over that 500 mark with stock cubes.
