04 zo6 compared to 06 c6
04 zo6 compared to 06 c6 I think I might know why but I want to hear from you guys what you think the difference is. My buddy has an 04 zo6 that is bone stock and I have an 06 c6 that is bone stock. Both cars on eagle f1 tires. We went to the track and he was able to muster 12.40 passes out of his car and the best I could do was 12.80 passes on my car. We swithced cars and I was able to duplicate his times in his car and the same for him in my car. The weight difference between these two cars aren't that different. I think the difference is the factory tune between my car and his. If any of you guys think differently,your opinions are welcome. Let's hear it guys!

I'm pretty sure the C6 has the same trans as the C5z. The only difference as you stated would be the weight and perhaps the 19's on the rear cutting your gear down a bit. What's the breakdown of the passes between the two (60',1/8,1/4,mph)?

I had the same experience between my buds 03 C5Z and my C6. My C6 even had a cai, cat-back and tune vs his cai only. We ran the 1/8th then some friendly roll racing. With similar 60-fts and even reaction, his C5Z always came out ahead. Look at the best C5Z times vs the C6. They make similar power with the C5Z usually slightly ahead from what I've seen. Those in the know say it's from the wheelbase to the TM in the C6. Maybe the slightly bigger cam in the C5Z plays a roll as well. Only when I got my long-tubes was I able to hang on street tires. Ran another well driven C5Z with cai, tune and DR's at the local track and he has been beating up on me. Now that I have DR's, my times are right with his. The C5Z in my experience is no joke.
I've driven f#ckloads of both types...
So much that I'm sick of driving them...
On my personal experience, I think the LS2 intake manifold is the cause for the lame performance compared to the C5 Zo6...
The LS2 even with the Z51 package (same tranny as the C5Zo6) is still a lame duck waiting for the rpm to rise...
My lil' 01 Zo6 rockets to redline in every gear, while the LS2 takes it's sweet f#xkin' time....
Not sure why, but it's true, and also the slightly longer wheelbase of the C6 makes it not as snappy when you touch the steering wheel side to side... plus the added benefit of the altered caster/camber settings of the C5Z and you have...
A winner... even though it's older.
Time for a drink... bartender!!!

Time for a drink... bartender!!! slllooooowwww to redline and when you blip the throttle it hangs in the mid rpm as it gradually settles... they (LS2's) all do that.
No comparison between the older Zo6... pimp smack time.

Verdad Gallardo It's an LS6 intake with the front throttle body area hacked off, and the front of the LS2 intake (90mm) plastic bonded together...
They (TPIS) claim a vast improvement in midrange tq/hp....
I built a custom carbon fiber intake cover for a customer that swore lt (the TPIS intake) was "worlds better" then the standard LS2...
If you add a FAST intake it can't hurt....
I also know of a guy who was the 1st in this area to add an LS2 intake to his 402 iron block WS6 and after a few months ditched it for the old LS6.... wonder why?
In addition to the intake I think the computer program is holdiong back, why would the rpm hang like that? (In all LS2 cars) and a few other tid bits...
I just got back from getting breakfast/brunch in an auto LS2 base, very nice up top, it broke traction constantly, but then again it's 40 degrees outside, much smoother car than my Zo6, but in a race I'd still choose the Z.

my buddy raced a few c6 vettes, one none Z51 the other a Z51.He has a 03 Z06. The z51 was close till the middle of second and into third my buddy started to walk away. They both had CAI on them. The c5 Z06's are hard to beat, chevy finally got a c6 vette, 08 with 430hp to run with the c5Z06's stock for stock. I think of the c6 as a cadillac and the c5z06 as a race car.
btw my buddies best time is 11.79 with just nittos, short throw shifter, vararam, kooks lt's no cats, and a set of rockers, untuned. My best is my sig. I spun out of the whole and should of gotten a better 60' time.

I would say it is in the factory tune on the LS2 motor..when they get warmed up they pull a lot timing and you have the dreaded torque managment to deal with too..If you get the C6 tuned by someone who knows what they are doing and get he TM turned down or off you will see a big improvment in the cars performance ..

I think its the tune because anything that is ls2 based is way detuned from the factory. The trailblazer ss picks up about 30 horses from a tune and thats at the rear wheels thru an auto so I know my vette is probably needing a tune bad to wake it up.

Pretty much my experience with my C6 vs my buds C5Z when we ran in the 1/8th mile. Right at third, thus near the finish in the 1/8th, he would start pulling. Thats with a tune on my LS2 as well. He had some sort of cai and stock tune. Once I got my long-tubes, then we were even. I've run another local C5Z (04) and he beats me handily on DR's vs my street tires. He drives the **** out of it. Looks like I've caught him and maybe slightly quicker mph with my DR's. I think he has a cai, tune and DR's. In the 1/8th or 1/4 mile, stock vs stock or even slightly modded, the C5Z owns the LS2 C6 from experience.

The stock LS2 breaths like crap. You need to fix the air flow problem then it screams.
Headers and a CAI do wonders for it. Oh...and the stock tune sucks.
I'll deal with the expense of a few mods if I don’t have to look at pop-up headlights though. ha ha That’s the only reason I got rid of my C5Z.
