i don't change my timing table. period. static. doesn't change.
actually it's -20 pisser juice if you want to get technical.
have i ever tuned a car? funny. try this one. how do YOU get a car to idle with 272 cams. how do YOU get a car to coast down with dieing out with 272 cams.
hmmmmmmmmm?
i know exactly what it takes to do this in an 07 lsj. what happens when gmr cams are put in? same thing with jbp cams.
can YOU run 13.2 afr at 25 degree's of timing? what happens above 12.4 afr on the lsj?

man dont listen to these haters
thats a real nice setup that ur running man
i hope to see that videos from the track man
z06 gotta loose sometime but folks on here look at it like a car that never loses
good job and good kill homie

it was stated that the vette was "babying" it at the track. and he still trapped 120. you are projecting a 120 trap speed for yourself. so in theory, the zo6 could still "baby" it and trap higher in the 1/4 mile. You would need a trap over 120 to just hang with him on the street. unless he is babying it on the street aswell. am i wrong? i just don't see how you could beat him in a legit race on the street with your projected time and trap speed. who knows, maybe your car will run and trap higher than you are projecting. but you did start the thread out saying that you were gonna run 11's, then you changed it to 12's when the haters came in. i just dont like to speculate. we should just put this thread on pause and wait for your track #s. that should give us a pretty good indication of the validity here.

how does afr NOT change when timing is changed? the way i look at it is, if the afr didnt change then why do you need higher octane fuel?
it makes sense, but i still dont fully agree. afr is messured buy how much oxygen that goes by the af sensor. if there is more unburnt oxygen doesnt that mean the afr changed (i do see you point of well then theirs unburnt fuel going past also)
thats what i dont get and is that statement true? i guess it would be true, but i still dont understand how fuel trim inst affected. i give up
edit: ok i got it. how about this. why is more octane needed, to slow the burn down, but if you change timing and not octane how do you get the same amount of fuel to burn just as long? wouldnt you add more fuel? what about that.

Please tell me you are not being serious. Listen up genius:
If there is unburned fuel going out of the chamber, THEN THERE IS UNBURNED AIR GOING OUT OF THE CHAMBER AS WELL. The amount of fuel sprayed in relating to the amount of air can be static, but the variable with timing will be EGTs, thus heat, heat makes power, heat makes things expand, heat makes pistons move. Not air, not fuel, heat. Thermal energy. Get it yet?

About OP:
Plain and simple you do not have a modded Z06 killer, much less a stock Z06 would most likely kill you.
About recent posts:
What are you all trying to prove exactly? A few of you seem to know what your talking about while others seem to be talking about perameters you shouldn't be changing anyway. It sounds like some of your cars would be faster if you wouldn't try to play with every single setting.

-----Since there is more energy present with the C16 there is also a greater potential for more power at the same usage. Since we can burn more fuel on C16 by advancing timing we can also add more fuel for the same given stroke. Since the laws of physics state energy isn't free and can't come from just nowhere and CERTIANLY can't just disappear, we have a better understanding of how adding more fuel by advancing timing will not change the AFR. This is because that thermal energy created from that extra fuel will expand more quickly than the lower octane in reference, thus increasing piston speed inside the engine. The faster the piston is moving downward on that crank during the intake cycle, the more air it will draw in per given revolution, thus we can add even more fuel and so on and so forth.
-----The other side of the coin goes for air also. Since we can cram more air in with better airflow, we can also use more fuel (which is why most people see a decrease in mileage when they add an intake or headers and such) OR since air can enter and exit the engine more freely there is less need to add extra fuel to make up the power.
You also asked the question: If you change timing but not octane, how do you get the same amount of fuel to burn just as long?
The answer is simple, you don't. This is the reason higher octane fuels just plain make more power. The reason you have to retard timing more and more as octanes decrease is because the fuel tends to EXPLODE rather than BURN. If the fuel detonates, that means the mixture inside the piston is not going to expand properly, instead it just kind of whacks away at the piston. Think of it in these terms with a crash test dummy: He's in a kia rio heading 50mph for another kia rio which is stationary and BAM smaks right into it. Granted the stationary car will move slightly, but the impact is so great that things just plain break. This is 93 octane. Now let's look at 117 octane. You are in the same Kia Rio parked right in front of the stationary Kia Rio bumper to bumper. Now you smash the gas and the other Rio starts to move with you and before you know it you're back at 50mph with no damage (pending the motor still working because let's face it, it's a Kia Rio). Granted it took a little longer to get to 50 with the 117 comparison, BUT this is kind of why we advance the timing. We give it a head start and it gives a chance for everythng to run smoothly and burn all the fuel it needs to without any of it exploding since it has a higher flash point than lower octanes.

Haha. I'll even pay for a camera person. I may have my friend Angie go up with me because she wants to run her Tiburon, but she's not the greatest camera crew lol.

Oh ok, nice. I have a pair of Hoosier QTPs 26x9.5x16 on steelies I was going to offer you if I end up being able to make it, but as of right now it looks like I have to keep the mrs. occupied for the day.
