great data, thanks!! I would've thought FBO stage 2+ woulda seen some increase from an upgraded intake. BMW did a great job with the n54!!... sort of lol
What happened when you turned the boost up to a reasonable level for that setup? Higher power levels would be the best opportunity to differentiate between the setups.
N54 life happened: I started getting a misfire at 16psi so I need to track down the cause before pushing it again at higher boost. I wanted to do a heap of dyno pulls at 10psi to ensure the misfire wasn’t present at lower boost, hence the opportunity to test the intakes in the process.
I agree that it may have a slight effect on the results but it’s harder to get consistent IAT’s on back to back pulls with the hood shut. The experiment would take 10 times longer and the dyno charges by the hour. The DA also changes over time so you introduce another variable if you spread the experiment over more time.
Do you really though? Doubt shutting the hood on a dyno simulates the amount of heat soak a vehicle traveling down a road would experience due to the lack of airflow. Would result in higher than normal temps if anything. If the car was in a wind-tunnel I could see it making sense. But hey, I am no expert... just a few thoughts.
Awesome. Always been interested in DCI vs stock airbox and to finally see a direct dyno comparison is brilliant
Thank you for the time invested to educate.❤
Not surprised with the results. I’d only switch to a DCI if I wanted more sound or easier access around the engine bay.
Thanks for sharing
Shame it doesnt show it on more powerful version (500hp+) as this would be interesting. Thanks for that though!

They definitely do a good job on their airboxes. Basically a ram air setup from factory
@@larrylegend4886 true, really most modern oem intakes are better for basic bolt-on builds than the flashy cheap options

Origin with KN is the best !
The intake that "delivers the most power" is the VSRF Hotside silicone intake. All other options are for those too lazy to do it the right way.
@@Gomepez perhaps, but us right hand drive cars don’t get the option to even try them.
You have to close the hood and let the car heat soak for proper comparison.

To do a proper test, the hood should have been closed, with a nice big powerful fan blowing onto the full front of the car.
Your dyno broken or the fact that 10psi is still stock even if it has all them mods. Be a different story if you were pushing 22plus psi
