Don't need'em. Witnessed a stock Z graft overlay from My tuner (who was putting AR's on his Z that day.verses My 08 with Vararami ntake & headers.On the dyno. Was a perfect match except down about 25 rwhp and 25 rwtq across the board. Tuner said himself change the cam, You would pull on my 07

could be the option difference. I have the 2lz with the power driver seat and 6 disc cd - no navigation, though

Would you notice a SOTP difference of 35 RWTQ through 2.5K to 3.2K RPM? I would assume I have achieved my goal of straight line SOTP acceleration being equivalent to a Z06 with 441 RWHP and 412 RWTQ. This is close to my dyno numbers.
I do not have any track times yet but hope to go Virginia Motorsports Park next weekend if my work load settle down.

What's more, I don't think they could out run a Z in my car either. That low end torque of the Z does wonders for the 1/4 mile times.
I ran 11.81 with gears and full boltons, which was a record for MZ6 trans at one time. Having driven my cammed car now, I bet I'm only going to run 11.5 on a great day. Stock Z's with a sharp driver and drag radials can run lower than that all day long.
If someone sends me a stock Z .drf dyno file I'll overlay it to my car's below. The Z's have more torque below 4k and that makes a huge difference.

No but He knows these cars inside and out! Ands treats your car like it's his. Eats and sleeps and works on Vettes.I've seen some good tuners. He is fantastic! He has a nice shop with the lastest tuning
equipment! He also has a car hell race you with titles up for grabs'
And It ant't his Z. It's got two hair dryers. Come on!
It would be WONG GONE!

Rock'n Blue 08 - Where do you see the difference in RWTQ and RWHP differences in your 08 and the Z06 Overlay? Also, what is your final dyno numbers? I took a dyno pull from a stock Z06 from LG's website and laid my modded C6 RWHP and RWTQ numbers onto the Z06 dyno graph and the graph matched perfectly except between 2.5K and 3.2k rpm. There's a 35 RWTQ & 10 RWHP advantage for the Z06 in the 2.5 to 3.2K RPM range and it goes back to dead even at 3.6K RPM the rest of the way through 7.0K RPM.
Would you notice a SOTP difference of 35 RWTQ through 2.5K to 3.2K RPM? I would assume I have achieved my goal of straight line SOTP acceleration being equivalent to a Z06 with 441 RWHP and 412 RWTQ. This is close to my dyno numbers.
Motorsports Park next weekend if my work load settle down.

I have a G5x3 and full boltons. While I've yet to wring it out on the track with the mods (times below are bolt on only) There is no way I will be running low 11's or even high 10's like Ranger and Robz can do with their stock Z's with drag radials.

A good cam will give 490 or so to the wheels on the dyno jet! later stock Z!

I have better than your numbers right now! I'm about 440 on a dyno Jet will know for sure tomorrow heading were I dyno'd my base of 378RWHP. 421 brwhp 410rwtq on a Mustang dyno with headers and Vararam!

The OP has an LS2, I thought the thread was can a LS2 be modded with cam only to beat a LS7. I still say no, based on my own experiences.
And the sharp driver in either car will beat an average driver in either. These cars are pretty hard to launch in the 1.6 range in stick shift form.

i have a c6 z51 manual
i installed Cutbak + xpipe borla
SLP Air Intake
Camshaft 117 lope 604 584
i had 410 dyno resualt 399 Tourqe
i havent installed headers yet
how much would the headers give me on this package ?
and if i had 430 hp result
how can i be more powerfull then the Zo6 ?
any suggestion ? and i am not talking about Supercharge or NOS
cheers

He certainly should consider headers in my opinion. Anybody? My car is lacking in torque and HP between 2000 to 3500 RPM when compared to a Z06. I'm not sure what you can do to a normally aspirated LS2 to bring up torque and HP on the lower end. Instead of doing heads on my car, I may save my money and put in a forged 427 lower end. I expect my lower torque numbers would come up. The quest for more HP never ends. I believe I need to joing some support group that deals with people addicted to HP and Torque.

Hey Joe, the original posted was interested in what he can do to his C6 to be more powerful than a Z06 with a normally aspirated engine. I'm not sure if heads will give him any benefit in the lower RPM range where the Z06 is stronger. I expect the answer is to add more cubes? He certainly should consider headers in my opinion.

A big cam, good set of heads (AFR or Trickflows) and a FAST on a LS2 will bring up low end torque say 30-40rwtq over my numbers. That will get very close to a stock Z06 performance. But if the Z06 owner adds headers forget it.
Bottom line, an easy and cheap way to beat a Z06 in a LS2 is to add nitrous.
But the cheapest mod is the driver mod. Note I didn't say easiest. I've personally enjoyed my path of learning to drive my car at a higher level. Executing a good pass down the 1/4 is like hitting a straight 300 yard drive (not that I can do that!). There's just so many things you have to put together to execute a perfect pass in a manual car. And because of track and weather conditions, it's never the same from one day to the next.

I agree Joe. If the original poster wants to be even with the Z06 throughout the entire power band he will need Headers, CAI, FAST, Cam with double springs, UD Pulley, 160 stat, Professional Tune and a good set of heads. That's the only way he will be able to keep up the lower end torque and HP numbers when compared with the higher displacement of the LS7 engine. He did not want Nitrous or a SC. To be more powerful than a Z06, I'm afraid he is going to need to add a few more cubes.
It appears I need a add a set of heads to my package below to feel the awesome pul of a Z06. As you can see, I already have a FAST installed. Here we go again!
Do you have a set of heads in your future or do you plan to do more cubes?
