Ahhh, you need a baseline in order to determine what the final gains are.

To the Original poster, I take it you don't have any baseline numbers on your vette, same day, same dyno, before any of your few bolt on mods were added on and your Z was bone stock, right?

camirocz

we must look at the gains and not the baseline.All z06 s basekine the same when they leave the assembly line.

I think your missing the point, or don't understand what a baseline dyno number is. You can NEVER determine the final/total gains on a dyno from any modifications made or any dyno tuning done, without first establishing what the baseline number was on the same Z06, same day, same dyno, same dyno operator, same correction factor.

Example. I drive my Z06 into my dyno tuner this weekend with my stock tune and CAI and B&B Bullet exhaust and we establish an initial baseline dyno number of 460 rwhp. Then I have the dyno tuner tune my Z06 without making any other changes to the car during the next hour and my final dyno number, after getting tuned is 490rwhp. My total gains would be 30rwhp. Final dyno number I make of 490rwhp, after tune or new mods are made, are substracted from my initial baseline number of 460rwhp, giving me my final gain of 30 rwhp.

Its really pretty simple 490 rwhp (after tune/mods) minus (-) 460 baseline=30 rwhp gain.

Oh yeah, also meant to say regarding your comment that all stock Z06s baseline exactly the same as they leave the factory is not correct concerning dyno baseline numbers. For instance, if 15 2012 C6 Z06s all leave the factory at the same time and are shipped to a local chasis dyno tuner, they will not all make the same baseline number on that same chasis dyno, same day, same operator, same calibration scale, etc. They in theory will be close, but their baseline numbers will vary between 1 and 20 rwhp. One might make 460rwhp, one will make 454rwhp, one will make 468, etc. Sure, some will put done the same number but a majority of them will differ some.

Most C6 Z06s and other identical cars for that matter, are going to show small differences regarding EXACTLY how much each car is putting down to the rear wheels on the same dyno, same day, etc. Its just the way it is, a majority of the new cars in my hypothetical are not going to be making EXACTLY the same amount of power at the wheels on the same dyno, same time, etc. Close yes, identical, no. Of course you know the difference between a chasis dyno and an engine dyno?

Hope that clarifies things.

Pull the engine and run it on an engine dyno and you will know your numbers are wrong. What JoesC5 said is absolutely correct, no and's, if's or buts lol.

Sorry to burst your bubble..

Dang let the Guy have a high dyno number... **** everybody gets all wigged out and bringing up oil viscosity and pumps lol. I dont think id be pulling my motor to prove myself right (or wrong) either. As mentioned earlier...who cares what the number is if there wasnt a baseline done. If I wanna say I dynoed 500rw bone stock...so be it...none of that matters till you are putting power to the pavement anyway.

500RWHP DIN probably isn't much of a stretch....my 2011 Z06 SAE corrected made 475RWHP with smoothing set to zero. When I select DIN correction and smoothing set to zero it makes 491 RWHP. A 1% variance in a dyno run could net me ~5 RWHP on the high side which could equate to 496 RWHP DIN and DYNOJET advertises that their dyno's are within 1% anywhere in the world.

Just to note, since my car had less than 600 miles on the clock when dyno'd....after more break-in time I'm sure to pick up a few more RWHP.

The whole point here though is the OP's car does not make any more HP than anyone else's per se. Give the guy a break....it's within reason and he's just excited about owning an awesome car

Ahhhh, finaly somebody has a 2011 model experience.
These datas seams to prove that this model has apparently more power than the previous ones.

I would like to have more 2011 and 2012 owners feed back to verify this.

Looked on chevy site "2012 Z06 505 HP" Same 7.0 liter motor. No way your only going to loose 5 hp going threw the transmission drive shaft and rear end.

Maybe the 11 and 12 have super low lost drive-trains?

This forum is awesome it is much more about entertainment than the Z06
The high whp might also have something to do with the valve guide issue that GM has responded to for which some elite 2011 models are part of as the identified range

No lets get serious: My little "Padawan" you must be new to this forum otherwise you would know that the 2006 model year is the fastest HOWEVER only in combination with with yellow color!

OK now some more food for thought. While I was still belonging to the dark side of the force and modifying my car my tuner told me that my stock AFR was ranging from 13.1 (peak torque area) slowy going down to 12.6 AFR near highest RPM. Reading this forum I always felt that there might be differences in the stock tune coming from GM???
Unfortunately my stock 2006 engine is long gone and now I have a stock 2012 engine and the beauty of the story is that it had to get the stock tune that my VIN is registered (AFR 13.1 to 12.6 at WOT) for to get the 3 year engine warranty. Now that might be a great combo....

PS: I also have the ZR1 exhaust and it truely sounds awesome on the Z06!

You can always drive up to Stuttgart where I am and put your car on the local Superflow Dyno I use for comparison. He prints out either DIN or SAE results (or both) depending on what you want.

I'm relatively certain you won't get 500rwhp on his Superflow, but I would love to see it if you do.

I got the exact same result here in montreal but:::::::::Pay attention the rear wheels were removed and so the reading is highly optomistic.What you have to look at are the gains .Cold air intake and tune gave me 30 h.p and that is whats important.Stock motors vary very little from one car to another.Lets not get carried away.There is no way you are making more than 485 whp with only a cold air and a tune.Trust me.Go to the track and your miles per hour will tell the real story if you have any doubts.

I don't know why you guys build your motors?
My stock Z dynoed at 600 rwhp just by adding a can of octane booster and the Tornado Turbonator, I bought off ebay for 19.00

Now that is one nice dyno room! Not to mention the high dollar SuperFlow AWD chassis dyno at over $125k here in the USA. I wonder what that thing cost in Europe.

OH THREE Z

I have a 2012 and have not dyno tested it yet, but it feels slower than my 07.

If you are truly making that power you should be able to trap north of 130mph... Can you? I trapped 124 in my bone stock 2012

I can't even imagine, but the guy gets a lot of business. He is one of the top Mustang tuners in Germany, but obviously all kinds of cars come from all over to his shop.

The engines submitted for testing have to be within ±1%, production engines can be within ±2%...so it's not exactly period.
