Hey everyone, i was wondering what the new ls9 is bore/stroke and what everyone thinks about a supercharged 600+ hp vette, i cant wait for the new camaro and would love to see the ls7 in it. thanks

 

i found the info, thanks for looking........2009 LS9

620+ HP/595+ FT-LBS
6.2L, 319-T5 aluminum block
103.25mm (4.06-inch) bore x 92mm (3.62-inch) stroke
forged steel crank
titanium rods
9.1:1 forged aluminum pistons with oil-spray cooling
356-T6 aluminum heads
titanium 55mm (2.16-inch) intake and hollow-stem, sodium-filled 40.4mm (1.59-inch) exhaust valves
Offset-rocker valvetrain layout
2.3L supercharger pushing 10.5psi boost
100HP/Liter target

 

So instead of looking yourself, you were wanting us to find it?

 

if you notice the date of my first post, you will notice it was on the 20th....gm did not give out the info until the 23rd.. and i did look and a couple days later i looked again and gee guess what i found. so you figure it out..........

 

Those are some wicked numbers!!

 

Good info thanks for the input.

 

so will the ls9 be a supercharged version of the ls3?

 

From what I gather it seems as though it is just a supercharged ls3. But the ls3 has what 430hp? + the 100hp added by the sc thats only 530hp. Where does the other 90hp come from?

 

better heads, cam, tuning, maybe?

 

Why are we limiting the S/C to a 100 HP limit? It's more than capable of producing more, especially with better heads and a cam to match. Not to mention it probably has titanium valvues etc. so they can push the rpm's higher as well.
