i think they have it worked out--- gm knows there is a problem with earlier models but wont admit it. word is later builds are running a different tune from factory. by december you should have nothing to worry about.

or just get an m6--- they're way better anyway.

If you plan on going crazy with the motor/tranny for the track, the auto is the way to go. A simple tweak of the tune fixes the lazy shifting, and the pistons are already fly-cut for running a big cam right from the factory. They have just cracked the surface of what the auto's are capable of.

give the guy a break, he has only posted 12 times !

Totally agree. I think the autos have more room to work with from stock. The fastest cars I've seen so far are slightly modded A6's. I believe the fastest is an auto with a tune and a shot of juice, 11.54 I think.

Those 3 mods are still with the stock restrictive cat-back on it. Since then he has installed a VVT cam and a new exhaust but he doesn't have track times yet. Here's a small clip of the car now with the cam:

The car comes stock with a VVT cam, do you know which after market cam he installed?

He and another vendor are working feverishly to get some hi-po VVT cams to market. Stay tuned, Mike is on to something for the auto's, be it good or bad, I think he is close to figuring some stuff out. Stay tuned.

I believe he actually trapped 111mph on the 12.6 run

LS3 heads are used in LS9 ('vette 638hp S/C, and in CTS-V), along with normally aspirated crate engines up to the CT525 circle track race engine.

LS3 crank is used in crate engines up to the CT525.

LS3 cam, while clearly superior to L99 cam, is not used in more advanced engines. This is one spot where LS3 offers tremendous opportunity. Cam + CAI + exhaust could easily net 100hp.

L99 does NOT use the same cam, crank or head as the LS3. Modding it WILL make it better, but until you yank the heads/cam, it won't have the same output, and even then, the crank's strength is still a question.

Interesting...What is your source? I thought the heads were the same.

This is clearly going to turn into a thread of people arguing over saying my standard is better than your auto. Some people dont want to drive around and shift all the time. Some people do. In drag racing an automatic is actually the better unit to have for consistency i mean cmon i dont think we have any pro career drag racers so racing straight up is kind of out really unless just for fun. A good consistent automatic is going to be the best bet in bracket racing. However in the standards defense you can leave at whatever rpm you want to leave at. You would need a stall for the auto. But a driver being able to shift the same everytime uh no. The main reason the standard cars put out more horsepower theres no secret sauce about the engines better. Its plain facts the standard takes less horsepower to turn it than the auto does. So just buy what you like and want both are great cars. Just buy what ya like.

Thanks. I am still getting an auto though.

Good choice. With a tune you will love it

Who is talking about bracket racing?

The standard turns the faster times, because it has BOTH a better motor AND more efficient transmission.

Buy what ya like? Sure.

But know what you're getting. The LS3 is a superior motor, from crank to cam to head.

An automatic is nice when you get trapped in stop N go traffic!

Gotta Love It!
