LS3 performance?
I am curious how the C6's with LS3's do in the real world. Are they that much faster than the C5/LS1 combo? Has anyone ran a C5 stock/stock and how much of a margin was there?
The reason I ask is because I have ran several LS3 equipped Camaro SS's in my (former) WS6 and they were dead-even with my WS6, even from a roll, which should have negated some of the weight difference (My WS6 weighed 3640 with 3/4 tank of gas, and me not in it).
I am wondering if the 'vette owners are experiencing the same, or if the C6's are stomping the C5's, or if they are just barely edging them out, or what?

I have run three C6's. Two of them LS2s, and one an LS3. My LS3 had a horrible clutch that made it hard to launch. Even with a really crummy 60' time, I managed a 12.4 in it. My best trap speed (on a different run) was 117.
There is no contest between a LS3 and a LS1 C5.

Well, I put my LS3 GS on the track after 700 miles on the odometer. Let me say by the number of passes I made I think the LS3 has proven itself. However,based on your experience your results may vary.

In terms of vettes, stock for stock, and LS3 C6 will have no problem beating a stock C5 LS1. Look at just the stock HP for an LS3.. 430, vs 350 on a stock C5LS1. Stock C5 will put down about 300-310RWHP vs the LS3's that are putting in the neighborhood of 380-390RWHP (give or take).
I forget how much the new camaro weighs , but I would think your Ws6 should not be able to beat one (speaking stock of course) just based on sheer HP numbers. Weight being pretty close between the two.

LS-3's ain't no slutch. I run a LS-7 ZO-6 on road course track day's, and the LS-3's are right there. C5 ZO6's are close too, but 350 hp LS-1's are pretty much left in the dust. Think there's a little more hp going on in some of these cars than advertised, or after a certain point unless you go huge, just make's little difference.

Just searched youtube for videos and suprisingly there aren't many good ones. There are however a bunch of LS3 c6s vs c5 z06s and they're about dead even. C5 Z06s stomp the regular c5s so therefore the ls3 vette should stomp the regular c5.

My street experiences DO NOT back up my track experiences. On the street, my WS6 performed like a high 12-second car that trapped 110 or so. At the track, it was a 2.35 60' 14.0@102mph car. I honetly don't get it. It did increase in speed from the 1/8th mile to the 1/4th by about 23mph IIRC. So it was strong on the top end me thinks.

Not going too far off topic here, but there is someone claiming 468rwhp and 435rwtq on an exaust/tune only LS3. I don't know enough to know if true or not, but it looks incredible and the potential is there.

Upon many of conversations Jesse came up with a great idea for the car. I was stuck to a pretty strict budget being all the prior mishaps with the car. His suggestion was to drop a brand new 2011 LS3 Camaro motor in it. We talked about building a motor but that was going to get expensive quickly. This was a simple solution and one that we hoped wasn't going to require extensive modifying to make it work. I am not sure how he was able to get his hands on one of these motors but I wasn't about to question it.
He installed the LS3 that got a full B&B exhaust treatment (no cats), flipped the stock air filter, and a tune. He was able to get 468RWHP and 435 Ft. Lbs torque. Dyno sheet attached. When he called and told me that I almost fell over! He made that kind of power with no cam no heads nothing internal at all. Drivability is basically, other than the stage II monster clutch and flywheel, stock except when your right foot gets a little heavy.

That is what I thought, too. However, my WS6 was dead-even with those cars well into tripple-digits. I was suprised, considering the new Camaro is supposed to trap 110 or so and my WS6 trapped 102 (with a horrible 60' as I was scared for the rear-end. Think it was 2.35 or something launching off idle and bogging bad with a full tank of gas to boot). It just doesn't add up, but I can't deny that what happened, happened, with multiple SS'es on multiple attempts.

I am sad that I sold my WS6 before I could mix it up with an LS3 'vette. I was not too awed by the C5Z. Probably about how my car would have done with LT's, LID, tune I guess.

with that claim.
How does LS-3 performance compare to LS-2 performance?

I have a 2000 MN6 (345 horse) sitting next to a 2008 MN6 (436) . Had them out on Saturday. There is no comparison whatsoever. I cannot believe how much better those 91 horses and the additional torque feels in the seat of my pants! No, I have no drag time slips but my '08 would walk all over my '00.
That being said, I still love my C5. It is no slouch. But the '08? WOW!

The LS3 dyno's I have seen are around 370-390 depending on transmission and car-to-car.
One of my friend's '06 GT0 M6 dynoed 347 with a CAI and a tune. I then went to the shop he got it tuned at when he got his FAST intake tuned and there were a bunch of other GTO's. The guy gained about 10-15whp like clockwork on every car he tuned. I am presuming my friend's LS2 had around 330-335whp stock.
The LS3 is not only larger than the LS2, it has a lot of little tweaks, too.
