Because of AFM the cam shaft is smaller then what you would find in a LS2.

Stock G8 L76 cam: 200/208 .472/.479 116 LSA

Stock GTO LS2 cam: 204/211 .525/.525 116 LSA

An intake and tune will bring it to 400hp and you can disable AFM too.

i dynoed 340 rwhp 350 tq with my only Real mod being gutted cats, and a smooth intake pipe to the stock airbox. so im actually now at would be considered 400+ crank hp..

Great mph for the lack of $ mods. I have run similar, but with the mods in my sig.

I would love to hear your exhaust.... any video clips?

I like how the stock mufflers sound when I step on it but around town it’s too quiet.

Yeah stupid DoD! I would get rid of it... the 2009 also has a few less hp because they installed an extra set of cats that werent on the 08's.

Just for comparison to your specs above here are the LS9 cam specs:

211/230 .558/.552 122.5

Its only a $100 cam from GM, replace the lifters with LS7 units, pushrods, valley cover. You have a cheap DoD delete kit that might only cost you $500 and have a nice 40+hp gain.

Hey Slow does the LS9 cam have a lope to it?

None, idles like stock.

That won't cut it, if I install a performance cam I want people to know my car has a cam.

ok i see now i wasnt aware of this, didnt know about the afm unit either, im amazed it runs on 87 octane also lol

The ECM pulls timing if you run regular gas, so you're losing some power. I tuned mine to run on premium and I can feel the difference.

I took out my 235/242 .618 114 and everyone knew within a half mile that the car was cammed... it was fun but after two years with that setup I wanted something a bit different.

Now I have the OEM LS9 cam, car idles like stock, and is faster! Granted I added a blower... haha

if you get an 09.5 you have 355 hp
