That means a lot. I am making sure to jam it full of good content. Next week is going to be insanity for you all. 4 rotor content as a blitz for sema. Officially happening haha
I can't even put into words my excitement for the future of all your projects, I've been a supporter for 5 something years now and won't be going anywhere, Thank you for the content no matter what it is Rob.
This video is EXACTLY what I was looking for. I was being lazy on cleaning my air filter and wondered, “will it make a difference “. Now, if you’ll excuse me, I’m going to clean my filter.
You should of cleaned the air filter and put it back in and run the test. Because the air filter would put restriction back in the system and you would not get that 50hp like you're seeing with no air filter.
@@miro5031 no one is denying there is some difference but the OP is correct... without testing the filter after cleaning then you have the TRUE HP LOST due to an excessively dirty filter.
Look at this 0-60 mph comparison between the least restrictive air cleaner element (K&N) and most restrictive (Wix) in a Chevy Suburban. Even the slowest was only 0.3 second different. Now, of course this would be more marked with a supercharger, but I was surprised the difference wasn't that great: ruclips.net/video/sJ3L-E-ufYo/видео.html
Dirty air filter = -50 whp. Clean air filter = some loss to no loss. Look up hot rod magazines test on air cleaners for carbed motors. Some filters actually increased horsepower over running no filter
Yeah it sucks he has a life and isn't one of those film everything and edit all night type of content creators. If he was one of those hardcore guys he would definitely be up closer to 1.5 million, but you only live once
I came here because I cleaned my air filter and was driving today and all of a sudden I floor it and notice way more torque than I’m used to and wondered if cleaning it had made a difference. I’m guessing it did! I bought the kit for it as well.
One thing I am seriously blown away by, is your slack attitude towards vehicle maintenance...! I feel for the 4 link RX7 project...! Starting to think you have more money than brains Rob...!!!
Which filter you recommend? The shitty paper ones that oem use but they use it for a reason... or the airraid... I feel like i wonder if you should go with a paper filter possibly? but they don't make one in cones huh?
Very misleading Rob.... should of put on new or cleaned filter then dyno. Air filters are restrictions. Lost 25 hp with k&n off vs on...on my turbo car. New filter. Your air fuel should of altered too.
No reason for air fuel ratio to alter unless you're on a TPS tune (generally only ITBs need that). It's not like the ecu can't measure the difference in airflow.
Felt like my car was slow looked at the filter didn’t look too dirty but I bought a new one anyways put in the new one now it feels like a new car. So I guess the filters don’t have to be really dirty so maybe once a month check them if that’s too extreme maybe every two months check the filters
When he showed the last clip at the end and said theres a lot more going on... I look at the rack in the back see twin turbskis... what does this mean rob!?!?!
Can you do a few runs on premium vs regular fuel on the same vehicle? I would like to see a few different types of vehicles. I am sure some will show different results.
But were your high power runs with the clean air filter or with no air filter? If it was just with no air filter, you haven’t really proven your hypothesis ... Psyched for your spoilers. And that ending 😄
You already know no matter what time it is I'm clicking on that Dahm notification.

You lost half a Miata in there.
😂😂😂
Shut up lol.

Get a bigger air filter, then you can neglect it for longer. LOL
lmfao 4:51 Actually had some tears from that ending, what happened to you at 5:01 Rob, mini stroke ?
I'm still laughing at this whole segment LOL
Is it the 4 turbos in the background?
i feel like he was thinking about going for another take but took too long to decide so it just came off as really awkward, lol
This is every youtuber in existence who makes multiple takes to find the best one. But, in this case, the worst take is actually the best take lol
😂 u was sweating their a lil Great video keep it up !!
10/10 outro

@@johnrroberts7900 I don't even remember writing this 2+ years ago, but I notice the increase in MPG's more than I do with HP increase.
This is the 4 rotor update I've been waiting for! woo!!
That outro tho
video starts @1:30
Illegitimate. The clean filter would have restriction. Not an accurate test.
Dirty air filter = -50 whp. Clean air filter = some loss to no loss. Look up hot rod magazines test on air cleaners for carbed motors. Some filters actually increased horsepower over running no filter
agree!
Rob I see you chasing 500K
SEMA and 4 rotor antics will close that gap even closer. So wild to see that many subscribers. Can’t even comprehend it
Yeah it sucks he has a life and isn't one of those film everything and edit all night type of content creators. If he was one of those hardcore guys he would definitely be up closer to 1.5 million, but you only live once
That ending lmao
Video should be titled "Dirty filter vs no filter." I would like to see the clean vs dirty run.
yup was bummed that was not the point of vdo

You earned your like in the last 20 seconds of the video.
One thing I am seriously blown away by, is your slack attitude towards vehicle maintenance...! I feel for the 4 link RX7 project...!
Starting to think you have more money than brains Rob...!!!
joke's on you. when i checked, there wasn't even an air filter in my car. somebody took it out and didn't put one back in. yeah..
Damn that Supercharger whine sounds real good
Well damn, been about 25k miles since I put my K&N on! Time to clean it!
Can't get over how sick the CTS looks 😍
Spoils have been read thanks for the info rob
I just ordered a K&N cleaning kit thanks to this video.
So we still have no idea how much a dirty air filter loses vs a clean one. Nice runaround
Love you rob dahm
3:16 ofc it does more power without any resistence from the air filter xd
Your a damn legend rob love your content
4:51 😂
Think Rob had a very long day, poor guys.
but what about the cheap one from Wal-Mart? haa! Love you Dahm
how much hp does it make with same kind new air filter ? must be lot less than 615....
What’s the exhaust setup
Kooks headers. X pipe. And stock cat back. Purrs like a cadillac should.
Rob Dahm sounds sick
Looks like I should really go clean my air filter that I haven’t done all year lol
That mad whine tells all you need to know. Night and day difference.
The damn ending had me CRYING 😭
how long did you not clean it for?
You really should do this with a clean filter to see the difference.
I’m legit dying over that outro 😂
Best outro yet!
Which filter you recommend? The shitty paper ones that oem use but they use it for a reason... or the airraid... I feel like i wonder if you should go with a paper filter possibly? but they don't make one in cones huh?
Definitely bought that Vantrue N2 Pro because of the video you did on it and I love it!

Whats the 603.82 hp from
i bet rob is a really funny guy after a few beers!!
even before
A little lost for words At the End Rob . Ill keep waiting for the 4 rotor . Its all been worth it all the run arounds rebuilds of the 3 rotor .
Holy shit what was that outro😭😭😂
YOU RUN E85??
How much does this have to do with the 4 rotor?
I actually wrote the whole secret in the comments. On my phone or I would copy paste. A Easter egg for whoever engages in the comments
Go read the replies of fdmtechs comment
Song? 4:40?
Damn Rob, this music got me in my feelings
Wtf 🤣🤣🤣🤣
3:10 that sound 😳
actually should have done 3 tests with the air filter as well.
That outro tho 🤣
The amount you were losing is more than a fourth my total HP in my car lol
Rob got that Kahwi Leonard laugh at the end lol
Surprised they don't have an inground dyno.... Wonder why such a temp setup?
it's just a rental- acedyno.com/
could have one just needing parts/repair (or don't need it enough to buy one outright)
That car sounds awesome!
Song?
4:51 WAT U SAY ??
When he showed the last clip at the end and said theres a lot more going on... I look at the rack in the back see twin turbskis... what does this mean rob!?!?!
Where the hell is the 4R?
Getting a rebuild....it travelled 5 miles soo needs a full overhaul
615 hp and 50 hp gained basically
0:25 ok but imagine having that statement on your car
when the drugs kick in 5:02
Oiled filters dust load 2-3x faster than regular filters
Can you do a few runs on premium vs regular fuel on the same vehicle? I would like to see a few different types of vehicles. I am sure some will show different results.
A middle school science project would have eliminated more varibles than this video.
But were your high power runs with the clean air filter or with no air filter? If it was just with no air filter, you haven’t really proven your hypothesis ...
Psyched for your spoilers. And that ending 😄
You should bring that CTS to Hennessey. They work real magic.
I like the end of the video 😂😂
Dude disqusting Rob ! Clean that thing more often ...👍❤Love that Car ! 🚘
Rob that awkward ending though 😁
Today, dad reminds us to keep our air filters clean.
Also, eludes the the alleged 4 rotor which we all know doesn't exist
That ending though.
another god dahm video from rob dahm and dahm i was fast to click on it
rob dahm is Ma papa anyway love from Australia
Lol @ the ending
That ending tho.....awk af lmao
The ending 😂
dat supercharger sound is so sexy
Great video to demonstrate what a dirty air filter can Rob you of... pun intended of course...hehehe😎
I should probably clean my filter now lol
oh shit...
brb, grabbing a new filter
I’m going to clean my air filter now lmao
Everyone is talking about the air filter but that red E-Class tho
yeah thinking of HP lose possibility when air flow restricted by factory@after market air filter wont cost ur pocket engine get ripped,god dahm it
Looks like I'm headed to Advance today.
daddy dahm
What did we learn here today clean your air filters or else you lose a lot of power
Lol my filter dirty as shit on my firebird, changing that immediately.
Good sh1t. Loving the videos
should've brought in your diablo or rx7 to test it
The end was weird 😂
We meet again
Wait why did he move to California?
“I keep my my filter dirty for more jdm’s “
I stopped everything too watch you love you
that last clip ahaahahahhahahahahaha
That’s where i went to dyno my car!!!
Dorito swap, when?
