Hey Everyone,
In today's video, we're myth-busting intakes! As we said before, we want to be 100% honest with our testing... and today, we're being brutally honest. In this video, we will be doing 3 baseline runs and we will be averaging them together. Then, we will be doing 3 more runs with the intake installed. Now, to be transparent, the car was limiting power a little (perhaps torque limit?), so the test isn't 100% accurate, but I think this still shows a pretty accurate view of what to expect. Most people buy intakes for looks and the incredible sound and they know that there are typically minimal gains, so most of you won't be surprised by the results.

This series should be called Brian looking for reasons to play with his new dyno lol
lmao
really wanna see high flow vs catless downpipe compared head to head with a tune
High flow Catted in my M340 was faster due to back pressure of the cats. Hard to believe I know but it was night/day difference when I went catless to AA Catted
@@varsity2845 S5 Audi is the same way. Basically no power gain from catless unless running bigger turbo(s)
Turbo cars do better with no back pressure so that’s false
This is such a cool series, I love it man!
Ahhhh, Transparency. It’s so refreshing to see. Props to Kies 👍🏼
BMW airboxes are very well made for performance from factory so it's pointless to upgrade them unless you want it for the sound and the show factor
At factory power you get no gain what so ever the stock intake was design perfectly for the factory power level you may get a few couple of hp with drop in filter when you start flashing the engine but intake mods only come into play when your talking about big power mods like turbo swap and built motor.
Brother!! I been waiting for your videos to come out.. lol.. I like you input and you honest answers... love your dyno video bro. 😎👍
Thanks Bryan you provide continually great content. Can't wait for my spoiler to arrive and oh this video made me buy this intake
Love this!! I need to come down for some product testing :)
Hi
We need more video on G01, specially the bm3 part on adjusting the exhaust sound, please
Love to see your honesty, that is hard to find. great video.
Just my opinion, you guys should have done one of the dyno runs with the hood closed for a real-life simulation. The intake is not really heating soaking as the hood is open and the fans are hitting that area. But nonetheless still a good test!
I wouldn't agree, if the Dyno was doing draggy times the heat soak would be relevant. Once a car is up and moving the cooler outside air soon clears the heat in the engine bay around the intake. If anything the reading is probably less as the fan speed doesn't increase the faster the wheels are turning on the dyno. I could be wrong and the fan speed creates an air flow like you're going over 100mph.
Kies is freaking great - love the videos, Bryan
You bro we needed this man THANKS 😊
Closed box intake is better on the car. (B58 Specifically) My 340 heat soaks big time because the turbo and and exhaust manifold are on the same side as the intake causing the intake to suck up all the hot air while hood is closed. Closed box intake is the way to go.
HEAT WRAP AND COAT THE DOWNPIPE.....THAT WAY HEAT ONLY HAS 1 PLACE TO GO......OUT THE EXHAUST ....PLUS THE BENEFITS THAT COME ALONG WITH WRAPPING IT....LESS HEAT THROUGHOUT THE ENGINE AND WIRE BAY PERIOD....MORE TURBO RESPONSE TIME AND POWER
Cool video, but I see one issue - you keep the hood open which allows more fresh air in. What makes the open intakes not good (safe for those that have closed - or at least semi-closed like MST design) is that they sit right above turbo, exhaust manifold and downpipe - which is a massive heatspot which is then trapped by the hood.
Thanks for the video Bryan! What about sport air filters? In my country intakes are illegal. I guess air filters don't add anything apart from a little sound right?
I must say any research I've seen there has never been enough gain to make the purchase and labor worth it.
After a stage two tune it will be worth it
Yeah, but that "WOOOOOOOSSHHHH" is totally worth it. LOL.
Definitely no labor costs if you have even the most basic mechanical knowledge
I feel as if you plan to do a stage 1 or above tune you should just upgrade the intake pipe and that's all in terms of intakes.
BMS intakes shows usually power lose due to it open design.Thats why I think all you need is a drop-in perfomance filter with a stockbox, and save your money for a full intake system. Thank you for your honest video. Much respect 👍
Thats what I did on my M2C, plus charcoal delete. Sounds is way better.
Сюткин Валерий mst is closed box but you do it for the sound anyway lol
@@dylan-nguyen Eventuri is closed as well.
Now do N55 stock intercooler vs aftermarket. Does more flow mean a tiny bit more power?
love this transparency 🔥🔥🔥
Mythbust an intercooler! 🙏🏻
You should also drive around for 50 miles so the computer can readjust to new changes... then test it..
Fastblade Productions Agreed. The ECU won’t know to add more fuel to the additional air the engine is receiving right away. In fact the addition oxygen mixed with the SAME amount of fuel would throw off the Air Fuel ratio and likely decrease power. This would be amazing of Brian to test as well, the “myth” of does your ECU really adapt to the mods (which in my opinion, yes it certainly does)
Or reset adaptions
That color is gorgeous, is that Dravit Grey?
Brian, please upload the F30 spacers video!
My dude I'm glad I'm not the only one waiting on that
Are you guys gonna do a boot mod ecu remap on ur next video on the m340
Great video!!!
I think the gains would be amplified on a higher boost car. Say on E30 map. I would like a comparison on that instead of a stock car on low boost
Mythbust intercoolers next, please!!
Would love to see what an Eventuri does to an F80. I'm looking to get one for my F80 and would love to know what I could expect.
It’s pretty much the same as any other intake. It’s just much more expensive cause carbon fiber
Should do a test on a tuned car ,,3 runs stock box,,3 runs open intake ,,,tune plus boost may get more benifet from open intake?
I did my M335i's intake and immediately noticed loss of torque -even on MHD S2 - but better top end -As long as ambient temp is BELOW 70F- honestly the awesome intake noise and blow off are the main reason to keep it.
pretty sure the intake is messing with the airflow dynamics over the MAF sensor, sending wonky reading to the ecu and cutting power accordingly. not sure about the b58, but on the n55 the stock air box has fins to direct / straighten the airflow before it reaches the MAF. I haven’t yet seen an aftermarket intake that integrates these airflow straighteners
G series has IAT and no MAF
Mate, it sounds better than my f80 M3, sounds amazing!
There was no myth :) intake only reduces the vacuum before the turbos. It makes a lot of sense for naturally-aspirated engines because of more airflow, but turbo engines build the same boost regardless of the intake. What it gives is a better response due to less restrictive airflow. With the intake, it's easier and faster to suck the desired amount of air. It becomes even more tricky not to lose power with the intake because very often people just put open cones under the hood and they suck very hot air.
Should have logged wastegte duty cycle to see if the turbo had to work less to make the same boost. I think gains will show on the top end with boost around 22 24 psi
Since it's X-drive could the T-Case clutches be slipping?
What is the change in sound with the intake? Don't care much for additional hp.
The factory setup is pretty good.
Do intercooler next!!!
///Myth Busters 🤟
Loving this
@kies Motorsports hey, have u allready tried to set the dsc on the car off, normally u just press the button and it says deactivated... but if u hold that button the car will turn the dsc off.. it's for sure a lot more fun on my rwd but maybe it helps u guys out. best regards
They perform the runs in 'Dyno mode' it automatically switches off DSC completely ;) (See previous vids)
They should also try it with XDelete.. maybe that might help with the power cut off
AFE DROP IN FILTER NEXT PLEASE!
Great video but can you please try a different intake
Wonder it the car was hitting tq limiter. Might need a xhp trans tune to raise the tq limiter.
I wish you do a dyno on BMW F30 N55
Intake is always tricky o the dyno.... it is probably the only add on along with ic that needs actual speed on the road to perform and the open hood with a flimsy fan does not even come close to actual on the road conditions interns of real time airflow.... if that makes sense :(
Yes sir..real world numbers vs Dyno numbers..I prefer street tunes myself as that's what the car actually does vs a Dyno which just shows number..both have their pros and cons for sure
Intake sounds good... does it lower air temp? My tuner says the cold air intakes don't help m235i due to bad airflow from the grills. True or not?
You can put scoops that will help a little to push fresh air into the intake. But to be sure you suck the air from the outside and not from under the hood, you should keep your intake boxed to eliminate any air suction from under the hood. And even after all of that, you won't get colder air. "Cold air intake" is more of a marketing name that means the air is sucked from outside. Properly designed factory intake will suck the same air of the same temp. The only downside is that factory intake is more restrictive. It puts more vacuum before the turbos, that's all. But the benefit is much less sand and much less damage to compressor wheels
I think the small hp gains are just from the filter element, not from the actual intake box. If u just stick a hi-flo filter in your stock box, you'll make the same gains.
You just copied my post :(
@@valeriysyutkin4940 sorry i didn't even see your comment, i just comment what was on my mind for the small hp gains.
@@Kai240i is there anything recommend for g20 330i?
@@shubdeepsingh8376any recommendations?
Can’t you put that thing in “drift” mode, and it will only be two wheel drive?
Do your F30 PS2 dyno vid!
Your results seem in line with conventional thinking. If you go into the BMW forums a significant group think that there is ZERO benefit from intakes. So a small gain sounds about right. Although, it’s possible that out on the highway at 70mph plus there is a greater benefit. THAT SOUND IS UNDENIABLY AWESOME THOUGH!!!
What color is that dravit?
BRYAN, PLEASE MAKE THE F30 SPACERS VIDEO!! PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE 🙏
Your hair grew a damn FOOT in a year.
Loving the M340i content!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Once again, this shows time and time again, that intakes dont do much, infact, I'd go so far as to say: that car will have a slower 0-60 time. A clean new paper filter with the engineered intake is the way to go. Most companies really cant hold a candle to the BMW engineers.
I wonder what the dollars spent per horsepower gained are. is the expense really worth only a couple HP or so? just a thought.
It’s not worth it for the power, but it’s worth it for the sound.
I bought a drop in filter what a waste lol. Not sure if itd make a difference on a n54 engine
I think intakes on most BMWs are worthless.
Agreed.
You’re judging all BMWs and all intakes off one vid is kind of wild
Why is the car only revving to 6k rpm?
Thinking 4 horsepower more
So ....... the big question is ... which I find wasn’t that clear in this video 🤔 does the intake give you any gains ?
He says it at 5:11. 4hp
yes, it gives, not power but response. it reduces vacuum before the turbos, so turbos faster and more easily build boost - that results in a more pleasant response. But that comes in the cost of more sand attack compressor wheels
haha not really. NOT the 16-20hp gains MST claims to give haha. I have this intake in my car. Purely for sound at this point.
Four HP
JRHOMEVID no it doesn’t
Do a RWD one too 😅
doesn't this thing rev to 7k?
If you have a 4wd dyno, why not just dyno it 'regular' mode and not dyno mode? That should work just fine. Does on a rolling road anyways. :)
puttitat2 dyno mode is a car test function. Without it you will get tons of car errors. Rolling road dynos are less accurate which is why they got a dynojet
I KNEEEEEWWWW ITTTTT
No tune? Good numbers
Do the Dinan.
Tune. It need tune
intakes on BMW turbo engines are mostly for looks and sound
at least this intake didn't heat soak and LOSE power
that's really all you can ask for
Mst has a pretty nice heat shield
I did a quick calulation you said 377 HP at the Wheels meaning it must have 490 HP at the crank! Are you serious?
yeah m340i are ridiculous underrated i have one and beat pretty much everything on the road
ehhh id lose some power to have a better turbo sound..
that going to hurt the engine because you rung hight RPM that is not recommending to manufactory from BMW....
First to comment...great to see all these before and after videos
370 I would say
OK so stock an M340i has 382 hp by BMW's conservative rating. You modded with a high flow downpipe and an exhaust and lost performance? Then added an intake which did little more than make the car sound better (assuming you like more turbo spool noise). I appreciate your honesty, but what does that really say about these performance mods that should be bumping up the hp up a little?
BMW's number is to the crank, what we measured was to the wheels. Normally, you have about a 15-20% drivetrain loss when you rate it from the crank to the wheels. Although some mods don't add a ton more power, sometimes they add different sound, etc, which some people really like, even if it doesn't come with large gains
No its better to just buy a filter , dont buy an custom intake.
So nothing of significance. Should have done a baseline with no filter.
first
get a draggy numbers, ur dyno is not relevant
