Angry First time on dyno with wierd results. Please explain!

Can someone please explain what settings are wrong with the dyno? Something was obviously set up wrong. I should have been at about 250ish? Notice the 10K RPM pull, lol. Im probably going o call the owner Monday to have it re done or get a refund. The owner wasn't there today, just the tech... I was kind of nervous being that it was my first time. Yes it's a 5AT with a Poopcharger noise maker, 5/8 spacer, and exhaust.


The only questions I was asked were vehicle weight, RPM limit, the longest gear, and the year. SOme pulls were in manual mode and some were auto with a couple 1/4 mile runs. 12.33 @ 107 is DEFINITELY wrong, lol. Is there any useful data to be puled from these? The trace is right, but the scale has to be wrong. I just decided to do this randomly since the place was around the corner.

Dyno's can have correction factors - looks like they use one that is very high. Why? Who knows, best to ask the dyno operator. On a different dyno you will get a different number...that is the nature of dyno's

My bad, I resized them... Z1. I'm stock with intake and exhaust mods. There's no way even with a CF that I could pull a 412.5HP. Or even 270. Im trying to find out the specific setting that was wrong so I can get another shot or my money back on Monday. I don't think the tech really knew what he was doing.

Why are some of the plots showing a negative Minimum HP? All of the plots with the high frequency data points have negative figures for Minimum HP. I'm, trying to extrapolate the data, but it hard to do it visually without decimal data.

I work with this type of data for a living (space flight hardware test data), but that is when there is an expected value, set limits, and verifiable calibration of the test equipment. Can any shops that own a Mustang tell me the correct settings to enter for our cars, with the consideration that I am 5AT with basic breathing mods?

12.33 seconds would make it the fastest all-motor 350Z in the world. How cool is that.

I like how the guy in the video told you that the dyno was right when you told him it was wrong

Find a shop with a Dyno jet dyno. Ussually more accurate results as a real number.

Ive never seen that black puff of smoke before. Scared the chit out of me. Thought I threw a rod or domething. Can anything useful be taken from the graphical data at least? I have a serious dip from 2-3...

The most useful thing you found out was never go there again.
