Hi Guys, I wanted to share this power and boost graph of an intercooled twin turbocharged LS2 engine in the 05 GTO as I believe that the 522 WHP (tuned on 93 octane fuel) is very impressive at such low boost pressure, good times ahead for the LS2 engine and community. I can see this current LS2 engine being retro fitted to many other GM cars in the future, all good. :) :zoom:

Here you go my friend, the exhaust note/noise is fairly quiet as the twin turbochargers are running through the stock exhaust system, still this gives you an idea of the power potential at higher boost pressure and with a free flowing exhaust.:)

Will do and I'd guess around 675 to 700 WHP on a dyno jet.:)
