Congrats on testing Dave, I am glad to see other people are testing the limits of our motors besides us 
There are a few things I disagree with and a few things about my car that might be unclear.
My personal G35 made 528rwhp @ 12psi on 93 octane. I drove the car for weeks on the street at 12 and 14 psi. I took the car to Willow Springs raceway with a few friends and filled it up with 100octane for added safety. The car was ran at 14psi ALL DAY. After 90+miles on the track (reset trip computer when I got there) the engine finally gave. The car was making over 550whp at this point, and I was driving the hell out of it, some where saying it seemed liked I was "trying to blow it up", which I was
If my car didn't blow at the track we were going to tune it for even higher numbers ( over 600rwhp ) and Sam felt very confident in doing so which is why I am not contesting your numbers.
What I do disagree with is how you like to call your Dyno Dynamics readings "REAL" numbers compared to a Dynojet. If anything the Dynojet's numbers should be considered "REAL" since they cannot be altered in anyway other than choosing the type of correction you would like to use.
On your Dyno Dynamics dyno you can make the numbers lower, the same, or higher than a Dynojet's readings very easily. So for you to say that your 563rwhp would be over 600rwhp on a Dynojet then you should have dyno'd it on a Dynojet. (Some people don't want to just "take your word for it" that you didn't apply any correction factors, at the end of the day only you would know the truth)
What I am getting at is there is no way for anyone to know if that car made 500whp, 560whp, or 600whp. If you want to compare numbers of the internet then a Dynojet is the BEST dyno for comparison across the internet.
Now, I do agree that the Dyno Dynamics is much easier to tune with and saves the tuner much time street tuning a car, but this does not mean that a competent tuner cannot tune a given car just as well on a Dynojet than on a Dyno Dynamics, Especially if the given tuner as been using the Dynojet for many years. Also to say that a Dynojet is not a tool tuning tool is rather inaccurate since we have been using it as a tuning tool for many years, as well as many shops for many different platforms across the country
None the less, nice job.

Thawk now you just jinks me, Ill porbably blow my motor this weekend at the track, and its all your fault

Nope, There was nothing wrong with my car or the tune. Just the amount of stress put on the car at the track, I doubt anyones stock engine would last at 550whp on a stock block at a full day event on a road course.

This has been a very informative thread for the FI community. Thanks for the research and work put in to the limits of the engine. Gives me a nice benchmark to shot for when I am tuning on my DD as well. Big props to your staff and may your company continue to grow in two folds.

At 19psi with C16, a stock engine at 10.3:1 CR would make far more than 560whp'ish on a DynoJet...wouldnt you agree?
To end all this debate, we are going to use shootout mode from now on. In this mod, it is IMPOSSIBLE to intentionally fudge the numbers, as the ramp rate, and all correction factors are locked out. And it also stamps the dyno as "ShootOUTMode", so people know they are true DD numbers.

I am not contesting the fact that he made 563whp at 19psi on C16, that is not very difficult to do. The only problem I have is the way he post this "REAL, Not Dynojet" I take that as he is putting down Dynojet readings saying they aren't "REAL" when in fact the only readings that can be questioned are ones from Dyno Dynamics machine. (not saying his numbers are inflated, just saying he shouldn't be putting Dynojet readings, don't you agree?)
Take care,

Open Dumps FTW!
