Time to get a different car imo.... 
Calloway show's 11.0 @ 1/4 which I suspect is does very very easy! Already tested my SC 600+ against a Z and it was a lot faster after 50 mph..... Perhaps it was just a slow Z...

Thank you for all of the help guys.
It's not all about speed for me. But I know that the base 436 is going to be boring to me. I had two 2010 GS's last year. Ended up getting a Z06 for one at the end.
I knew I would miss the topless ability, and well... Here I am again. I think that if I go FI with the GS, I will enjoy it alot more.
I would most likely go with a maggie, or whipple.

If 606hp doesn't beat 505hp in essentially the same car something is drastically wrong! Time to get a different car imo....

If you tested it in the real-world, heads up, I would be curious about the whole thing, though. PM if you want.
I never understood why they weren't trapping faster than 125 in the SC606, but I have yet to see a 1/4 mile pass in one that did. Plenty of Z06 passes are better.

11.0@125 on a set of slicks isn't going to beat a well-driven Z.

just kidding you! Actually I've wondered the same thing about the time Calloway shows on the 606..... perhaps Chris was driving?

Thanks for the good words guys!
A supercharged GS manual trans lays down 575ish to the wheels with an ECS Base Blower package.... and about Equal Torque. It can make more, but thats generally limit them. It will eat a bone stock Z06 for lunch - at 430 RW. (which is what a stock Z generally puts down on our dyno.)
Here's a couple of graphs....
Otherwise Stock GS LS3 - With a ECS Paxton 1500 (base kit)
Stock GS with ECS Base Blower Package, Heders and Meth -
Stock Bottom LS3 with Headers, ECS Blower Cam, & ECS 2200 Kit (with restrictor plate installed - there's still more room to grow here
)
BTW, all of these have pretty much stock drivetrains.... And at least a few of them are run pretty hard.

glad I don't have a bone stock Z06. Most who hit the drag stip/track don't. I'll take a LS7 to begin with over the LS3 anyday; not to mention the lighter aluminum frame. Being able to make the kinda power the LS7 can and stay NA and be ~200lbs lighter than the equivalent supercharger GS is a bigger deal to me.
and no doubt, there are other benifits to the Z.... but with a 100+ rw deficite, it wouldnt be much of a fight against the blown GS.

umm a ls3 is internally stronger than ls7 especially considering an ls7 cannot handle being boosted for long due to its thin sleeved block.
ls7 is more powerful stock... but an ls3 can handle more power and keep that power longer before blowing then engine then an ls7 can... and that is straight fact.
id rather have a blown ls3 over a ls7 or blown ls7 anyday of the week
i love the z06 and i am not knocking it because it is a great car... but id rather have an ECS blown Grandsport over a Z06 or zr1 anytime

i dont know what your are talking about but my full bolt cammed ls3 is making close to 500rwhp. with a fast 102 and NW tb and a heads job it will be making more power then your z06 straight NA. the z06 has a lighter frame but the base c6/grandsport has a stronger steel frame. that is why the z06 is a FRC for the reason that it was not sturdy and needed the roof to be fixed otherwise it was dangerous.
And personally, I'd take a mid 500's whp Z06 over a 600ish whp ECS blown GS (oh wait, I did). Weight is important to me.

iceman im not knocking you or your car like i said i love the z06 and you have a really nice one. money is no object for me but i am making a logical explanation here.
zr1 equals 100k with forum discount. you could get a grandsport for lets say 50k. throw in a ecs supercharger, blower cam, and meth kit and your at 60k. now spend 10k in brakes and suspension which is even too much and your at 70k. at this price you have a car that will obliterate a z06 or zr1 on the track or the street/ strip and still put 30k in your pocket. and still cheaper then a z06.
Id rather have more for my money... and in the case i stated above you GET ALOT MORE

I believe the Grand Sport with the dry sump LS3 and the manual trans has the same clutch, and differential as the Z06. I believe the transmission is the same, other then the gear ratios.
I also think the E-Force on the GS dry sump with the manual trans, is a great way to go. The extra ~200 lbs of weight(vs the Z06) is offset by an additional 20 horses. ~500 whp with the S/C'd GS vs 445 whp with a stock Z06. That makes up for the additional weight plus some.

A supercharged GS will not "obliterate" a ZR1, and would barely beat out a stock Z06. On a track, it would be a drivers race against the Z06 and the ZR1's superior brakes and suspension would easily allow it to "obliterate" the GS.
I just don't see the supercharged GS as good of a deal as some are trying to make it out to be. You need more than just engine numbers to make it reliable, or a track worthy opponent vs a Z06 or ZR1.

My understanding is that the Grand Sport with the dry sump LS3 and the manual transmission has the same clutch, transmission(other then gear ratios, and differential as the Z06. A wet sump GS with an automatic transmission has the same driveline as the base C6(except for the differential gear ratio).

My Z06 puts down 540whp, with longtubes, intake, small cam and a tune. With the weight difference between a Z06 and GS (especially a supercharged GS) it is going to take more power from a GS to equal the straight line capabilities of a Z06. Not to mention the fact that you could also put a supercharger on a Z06.
Point being, you can get similar power as a low to mid boosted GS from a Z06 and stay NA; all while having less weight. Equal mods, the Z06 is a better car than the GS all day long.
But, in your situation, you already own a ZR1. I would do intake, longtubes, cam, tune on the GS to stay NA and have a removable roof. And keep the ZR1 for the forced induction fixed roof.

I'm a fan of the Z06. could always FI the Z06 down the road too...

iceman you gotta be in some sort of denial... ECS just posted a graph for a bone stock ls3 with a novi 1500 supercharger, headers and meth kit.
THE CAR MADE 699rwhp and 645tq. that equals- 804crankhp and 741rwtq ahahahah. your right THIS supercharged GS wouldnt oblierate a z06 it would SHAT all over one and then some... along with the zr1.
z06- 505 crank HP and 470torque.
Zr1- 630 crank and 600 torque.
your telling me a grandsport with 300 more hp and almost 300 more tq is barely going to beat out a z06.
now for the track... you take all three cars with the same driver and i put my money on it everytime the supercharged grandsport spanks the z06 and zr1 times.
