Default Dyno run on 2019 Base A8 6th gear pull

2019 Base NPP with 1100 miles, is this about average? First run (1) with the plastic forward cover under hood on passenger side and second run (3) with cover removed. SAE and Standard. you can see it made more power and torque with the plastic piece removed that covers the hole in the fender that is above the air filter.

I was going to guess about 410hp but removing that plastic piece really made a difference. Best free mod yet.

60 was a little off my best 1.68, Only had a few run on this car. Have not had a chance to run a good 1/4 yet. Hope it get better with more miles.

Next time you dynojet

Use "Uncorrected" if at sea level
Use "Smoothing = 0" So you can see the torque curve proper
And get an A/F curve on the bottom so you can actually see whats going on in there.

what can we tell from the graph (just by looking at random graphs- without knowing anything about the car)
- just by looking at the curve, the motor appears to make around 430ft*lbs of torque to the tire at whatever peak VE is for that engine (most likely 90% or more)
- And it stays peak VE until 5k and barely taper off. So its got a very good camshaft for mid-range, daily driving street-ability, etc... evidently (stock usually is).
- the curve looks typical for production, newer, combustion engines. That is, it appears "correctly shaped" and there is no indication of misfire or other troubles internal.

He said that it was having knock but all that he tests stock sees knock. We only have 91 octane , maybe 93 would or should do better. This was done at about 375' elevation.

What cover do you remove? Do you leave it off all the time or just when you dyno or drag it? How does it help removing a cover?

Can't hurt, just another avenue to pull more air from.
