2010 VS 2011 VS 2012 V6 power

[brandonrr]

i already know the 2010 has 305hp, the 2011 312hp, and the 2012 323hp, but what i'm wondering is how much of a difference is there when driving and how noticeable is it?

i am really curious how the 2010/2011 LLT compares to the 2012 LFX with the integrated exhaust manifolds and composite intake as well as it being an entirely different engine.

when i drove that 2012 v6 mustang, i was surprised how much less power it had than my 2012 camaro LS, despite them both being stick-shifts, and the mustang even having a very slightly higher axle ratio. (3.31 mustang, 3.27 camaro)

i also remembered that when car and driver compared the 2011 v6 mustang and 2010 camaro, the mustang was actually very slightly faster from 0-60 (by .1 sec).

so what i'm asking is, has anyone driven a 2010 camaro and then driven a 2012? if so, how much power difference have you noticed? same question goes for 2011 and then 2012 or even 2010 and then 2011, but i am the most curious about the 2010 then 2012 for comparison.

also, i understand that an isolator makes a big improvement in the 2010s and 2011s, due to the alloy intake and heat-soak. if there is a big power difference, like i suspect, i am almost positive the manifolds are to blame for the difference. (or most of it at least)

The HP rating for the 2010 LLT was based on the certification for the Caddy. They had it recertified for the Camaro in 2011 to get the 312 HP. It is exactly the same engine for both years so there is no difference in HP. The 2012 got a bump in HP that is about equivelent to adding a CAI to the LLT. I haven't driven one so I can't tell if some of the other issues that a CAI fixes (a little less heat soak, a little better throttle response) are comparable to the LFX. As for the isolators, they are to prevent heat soak and increase the runner length a bit. They should provide a noticable difference, especially with repeated runs at the track or on long drives.
