I think Autos still beat SRT8 instead of 426HP, its 400HP at the Crank. I Think thats still higher than the SRT8...

did I just stumble under a bridge? kinda smells like troll.....

just in case I didn't.... The L99 has Active Fuel Management which does shut down cylinders, but it cycles which ones are on and off to keep the engine in balance. Doesn't necessarily just shut down to 4 cylinders as far as I'm aware

Yes, the L99 has AFM, which shuts down half the cylinders when cruising or at idle.

you would think they would get better gas mileage than the v6's then.

yeah, it's not exactly as black and white as less cylinders = better gas mileage

I bet putting a 4 pot in this car would get terrible mileage beacuse it would have to work so hard to move the thing around. I know my s10 originally had a 2.5 L and when I swapped in the 6.6 L I didn't lose any gas mileage really in the city because the engine hardly had to work at all to move that truck around. went everywhere at 1200 rpm rather than 2500.

and you have to take into account that the engine isn't ALWAYS running on 4. so it'll be some sort of average between 4 and 8 depending how hard you drive it.

is reason for the quiet idle in the L99 the AFM? i've listened to two auto SSs at idle and they seemed quiet... are the LS3s louder at idle?

I think AFM only shuts off cylinders under light load crusing, but runs on all 8 at idle to keep the idle smooth.

The SRT8 has 425hp. Camaro will still have a slightly better weight to power ratio, though. It will probably come down to a drivers race. Whether the SRT8 has a manual or automatic may make a difference too.

only problem with that is that I thought it cut down to 4 when cruising. So it doesn't need to "lug" all that weight since it's already in motion. No?

It takes a lot more energy to accelerate the car. Once you are just cruising, it takes very little power to keep the car in steady motion on a flat surface.

The idea behind cylinder deactivation is that cutting to 4 cylinder mode under a light load increases thermodynamic efficiency. When just cruising under a very light load (maybe 5-10% throttle), engine vacuum is very high and there is very little air available for the engine to pull into its cylinders. With all 8 cylinders trying to pull in a very limited supply of air, each cylinder gets a very weak "charge" of air and fuel, less heat an pressure is able to build in the cylinder during combustion, so less work is able to be done, and the engine becomes less efficient.

By going into 4-cyl more, each operating cylinder gets twice as much air as it otherwise would, increasing cylinder temps and pressure, giving greater thermodynamic efficiency (more work is being done per unit of fuel used). It's the same basic reason engines get more efficient (and powerful) as compression ratios increase, or as the load on the engine increases. Under a very light load, the L99's probably make just as much power (or maybe a little more) running on 4 than they would running on all 8. The system only changes to 8 cylinder mode once the throttle is opened enough for all 8 cylinders to breath enough for there to be a power benefit.

The first thing I would recommend for you is to do a little research on stuff before you just start playing around with the car and have no clue as to what it's doing and the consequence of what you are doing.

Sounds like you are making changes first and then asking questions later. Not really the best way of making upgrades to your car.

One of the reasons that the SCT is going to be better than the Diablo (for the L99) is because the Diablo doesn't currently have a way to modify your transmission settings where the SCT does. The transmission settings are a big issue on the L99.

I'm assuming you probably don't know that by tuning your car you've taken a significant chance that your drive train warranty will now be voided?

a L99 2SS stock camaro will beat any srt8 0-60 and 1/4 mile - according to every motor trend vid ive seen.

think of active fuel management as this - cuts down to somewhere between 4-8 cylinders during times of low stress/acceleration; it kicks them right back in when you step on it. if you turned your dod off, then your afm is off (mines off).

no offense - predator tune is crap - all shelf tuners are crap. spend about $150 more and get a custom tune and have it dyno'd (before and after the tune) to see some real numbers. when you figured with a k&n filter and predator tune - you would be lucky to get maybe 10 at the crank. ask anyone who is honest first of all and has done this. after a quality CAI, magnaflow 3" stainless comp series cat back exhaust, and a custom hp tune - i gained 20rwhp and 13 ft lb torque. thats real.

i would also suggest for you (i'm getting this soon) - underdrive pulley kit. will knock off parasitic drag and you will gain a few more hp.

Good luck!

Brad
