Horsepower isn't everything. The auto is more consistent at the track and tends to finish first with professional drivers. You can't shift as fast as your computer.

this is true. as you move up the ranks you drift away from true manuals very quickly. google Lenco. it took a while for the technology and knowledge of materials science to make planetary gears durable for very high horsepower (2000+). I've been away from drag racing for a few years, but I know the higher level sportsman cars are starting to run autos/converter drives more. source: I used to race a 7 second dragster with a powerglide.

Any tune will be able to disable the AFM, but if you are going to get the tune you might as well do the dyno tune. Much better results, more specific adjustments for your car.

Also, like others have said what is your end goal? If you want a consistent drag strip/street car you will want an auto. Pretty hard to beat a computer.

and the lower hp in automatics is because of higher drivetrain loss, aka the "resistance" the power goes through as its transmitted from the engine , to trans, to the rear end.
Advertised hp at the engine has nothing to do with drivertrain loss through the drivertrain. A 400hp engine rated at the flywheel (or what manufacturers advertise at) is a 400hp engine regardless of what transmission or other driveline parts it has.

The difference in hp between the automatics and manuals is due to some parts of the engines being different.

I'm looking to trade up to a v8 as well and wanted to ask the same questions. Thanks for the post.

it seems like every other day i read a new thread and no matter how its started somewhere along the lines it turns into auto vs manual. Which turns into my auto is faster than your manual at the drag strip, but last time i checked i wasn't able to find and Ls3 to L99 conversion kit. The debate will go on forever but at the end of the day they are both camaros so its a win win...

What do you mean you can't find a l99 to ls3 conversion kit?? Just about everyone sells them.

Ahh.. typo.. got it.

But I still disagree with your argument. You're comparing engines in a transmission argument. So:

LS3 > L99
&
Auto > Manual (In high end drag racing.)

It deletes AFM, DOD, and VVT. Making it a little stronger. Usually only done if pushing big boost from a superchager or turbo. Or done if switching to a blower cam or big lopey cam. Tuneing required.

ditch the afm lifters and tuning it out is a good thing. i know of no magical way that ditch vvt all of a sudden makes more power. i urge you to take a look at properly tuned and modded vvt setups. doing a ls3 conversion might be easier or better put more readily available due to less tuners feeling comfortable with dealing with vvt.

What is VVT and DOD? So the conversion kit keeps it an automatic just with same characteristics as the LS3?

Variable Valve Timing. A pretty cool thing that allows the cam to have a wider powerband, however if going with forced induction or big lopey power there are concerns with it's reliability.

DOD I can't remember but I think it's the physical parts of AFM in the engine.

The L99 is just a slightly modified LS3 and the conversion makes it an LS3 again. It has no affect on the transmission.

Don't get caught up on 25hp. It doesn't make that big of a difference,
It made a HUGE difference to me. I bought the LS3 after driving the L99 first. Liked the paddle shifting but there is a noticeable difference in these cars/motors comparing stock to stock. I am so glad I have the M6. Way more fun to drive and I don't care how fast a computer shifts. I like to drive, not ride along. Just my opinion but drive both the auto and manual and decide from there and do consider possible future mods and if you will race and what type or racing you will do.

Most def. I believe my "career" best was 7.28@186. The car now sports an aluminum block, rods and two stages of nitrous. My dad has gone in the 6's.

PS..I used to hang burnouts out to 200ft because I could (and they weren't my tires).

If the dealership has two identical Camaros except one is Auto and the other is Manual, I'll drive them both. But if there is a yellow one thats manual and a cyber grey one that is auto. I'm taking the Auto

I agree except for the 25 hp is not the part that made the difference. It was the massive torque management that they imposed on the auto that makes them feel different. I personally went auto b/c I knew I wouldn't wait long to tune that out. Now I'm eating up those manual 5.0 mustangs!

Are you saying the Autos have more or less torque?

The engine is the same but the programming makes it feel like it's less b/c it prevents excessive wheel spin off the line from a dead stop. The manual also has a gear that is just a little bigger in the rear end, which also makes that feel more torquey. However if you end up adding power later, the manual breaks axles ALOT sooner than an auto will.

Tune it and the torque feels like the manual.
