LS3 vs Z06
I have read several posts and it appears LS3s are responsive to mods.
Will a:
2008 LS3 6 speed coupe (NPP+Z51) with headers (Kook or LG pro longtubes), CAI and a tune keep up with a Z06? How much HP increase can I expect with headers, CAI, and a tune?
Will I need a cam? Which cam is recommended (would like to keep it as a daily driver) and how much more power with the 3 mods mentioned above? Trying to be in the Z06 territory with only bolt ons, if at all possible.
Seems like it's not worth touching the heads.
Thanks!!

No, Z06 avarage RWHP is +440
You'll need more than Headers and a tune! you'll gain like 45 RWHP (Maybe!) from all the above
wanna keep up with the monster Z? get a decent Cam and UD Pulley plus all goodies you mentioned!

Here we go again. You are going to get the Z06 boys all riled up! The fact is that just matching or exceeding the Z06 hp is only part of the story. The rest is the suspension, brakes, lighter weight, bigger wheels, more torque, dry sump oil system. Sure you can mod a c6, even a lowly LS2 like mine to out hp a STOCK LS7, but don't forget the Z can be modded also and most likely the ones you run across at the track will have at least a tune, CAI and headers. Personally given employee pricing and low interest rates I would much rather have an unmodded Z06 with an intact warranty, than a modified LS3 any day of the week. You will spend at least 5K modding your LS3 to get close to a stock Z, you might as well spend another 10 to 15 and just get a Z.
Oh and to answer your original question, no not with just headers, CAI and tune.

FYI: I've only seen one Z06 on the track. With drag radials, the car ran a 12.2 with an experienced driver. Outside temp this day in March of this year was 60. I have a friend with an 08 automatic car that ran a 12.34 last weekend with outside temps aroiund 80, on the same track. The 08 is bone stock with stock tires. Personally, I suspect that the LS3's are making more horsepower than advertised, and with a few bolt ons should et with sub-12 second times.

In life, I learned to be happy with what I have. I just want to be close to a stock Z06. I bought my 08 3LT for $51,XXX at 0% interest. I could not justify (having a tight budget) spending another 15-18K for a Z06. And the fixed roof.
I think I'll end up with the 1-7/8 headers w/cats + stock npp exhaust, CAI, and tune. $4-5K in mods I can do. And I'd like to keep stock MGP so I would prefer not to touch the engine.

A modded auto with a 3.42 is going to run pretty well. You still beat them with a stock Z06, which just drives the point home. Equal drivers and an LS3 with CAI, headers and tune isn't going to out run a stock Z.

Your correct. I ran against this guy when he was stock and then with mods. His mods made a huge difference to his car. Stock Z06 will beat his car. But those C6 with the A6 respond well to mods.

An 08 with supporting bolt-ons and a cam would be close on the track. Let's see:
Cam install with tune special - $1795
Headers w/cats, another special - $1700 complete
CAI - $400
Aproximate Total - $4000
Average rwhp depending on the cam - 430-465

Yeah your probably right, those Z's are overhyped they probably don't even make 505 hp and the LS3 is pobably making way more hp than advertised even though they are both tested to the same standards. This subject has been beaten to death, check out the fast lists for the LS2, LS3, LS7's your answers lie in the facts presented there.

One of the biggest factors people seem to forget it what heat will do to a stock tuned car. If a stock z06 and this modded LS3 vette are sitting in line waiting to make a pass at the dragstrip and getting hot while doing so, the stock z06 will start pulling timing MUCH more aggressively and reduce HP alot. If both cars are given the time to cool way down and pull right up to the starting line without heating up, the LS3 gets walked no matter what(unless the z06 driver can't drive worth a crap). The modded LS3 is a fast car but still not fast enough.
Eurorod said he saw an experienced z06 driver run 12.2 on DR's and then a LS3 run pretty much the same et in 20' hotter weather. Either you meant the z06 ran 11.20's or your "experienced" driver can't drive worth a crap. In 60' weather a z06 with DR's should be in the low to mid 11's.

You have to remember the rear ratios as well as the transmission ratios in an 08 Z51 car are much shorter than the Z06's.. I have a full bolt on 08 Z51 car in DFW (frisco). It puts down very similiar #'s to a stock Z06. I would love to run a stock Z06 to see how they measure up.. Anyone in DFW w/ a Z06 that wants to play?? Looser buys dinner at the closest Twin Peaks or Hooters!!

My ls3 with haltec & tune against z06 with also haltec & tune. Mine is a6 and he said I scared him to death. I killed him at the line but he caught me. Results, mine 12.1, his 11.7. He said if he had to do it all over he wouldn't be shifting gears and he'd be about $20,000.00 richer. Both stock tires. This was also before my a6 tune. Haven't run since.
