If you want a convertable or Targa top, the modded LS3 is your best option.

That is what I meant, Removable top!!!!!!!!!!!!1

LS2 Corvette vs LS3 Corvette with just Headers and cold air:

Many have been asking for this comparison so we put the graphs up together.

Both C6 Corvettes had LG Pro Long Tube Headers and a cold air intake. THe LS2 had a halltech cold air and the LS3 has a K&N cold air

the other difference is that the LS2 (06 C6 Corvette) has a "Tune" and the 08 C6 LS3 does not have any tune.

Other than that, both have no cats and each has the same muffler.

Thanks
Lou G

They both had "Dual Mode Mufflers". We put a C6 Z06 muffler on the C6.

When are you going to have a chance to tune the 2008?

Very good! Looks like the LS3 is putting down pretty close to what GM says although the two you tested had headers and intakes. LS3 however without a tune.

Larry, it drives like a 228 cam, untuned in a 346, maybe a little better.

Surging is only evident in 6th gear on the highway below 1500 rpms.

Im hoping to get a tune in it by tonight if I can.

Louis you guys have a million people on the edge of their seats just waiting to read the updates on the LS3 ..... How much longer before the ported heads are ready ?? Do you think the heads and a tune will be enough to get in the 530 - 550 rwhp range ??

Thanks Lou! Looks like it will need some tuning with the cam. Perhaps none with just headers and intake?

Wow.......cam only Vette's approaching 500 RWHP. That's awesome. Makes my original GenIII LS1 look archaic, even with the TT's.

Does anyone have the numbers from the 08 with headers, CAI, and tune yet (without the cam change)?

Really curious!

Hey Doc,

If you go to LG's website you should see an M6 car (2008) that made 420ish rwhp and 400 rwtq with headers, K&N, plus a tune. The cammed car initially made 480ish without a tune. 500+ with a great tune in place.

Stick around, some of the secrets of the LS3 are still waiting to be unlocked. Just give LGM some more time and I am sure we'll see the first Cam only LS3 making 510+ rwhp. Way to raise the bar.

Still waiting to see what she'll put down with some ported heads.

As previously stated.... my lil' LS1 is looking more and more like a dinosaur. A stock LS1 with a supercharger would have a heck of a time making that much power (safely).
