How much hp or boost can a stock 2011 ls3 hold and still be dependable
 

Guys just picked up my new 2011 ss friday pretty sure I'm going with a quick time turbo set up can anyone tell me how much HP and boost you can safely run with out going into the block thanks

In my opinion anything above 600 rwhp is pushing your luck. Most LS motors are able to handle up to 600rwhp no prob, but once you bump over that mark you are definately pushing the limits of the stock internals.

Thanks for info would like to make 675 to 700 whp so guess I'll look in the block sux spending 50k on a car and havin to tear the motor down before it has a 1000 miles on it

Yeah I wouldn't expect a stock LS3 to stay alive at those levels for too long.

The block isn't the weak point here... Pistons and rods.
