HOW TO GET 500HP FOR LESS THAN $1500 ON A B58

The b58 is a great successor to the n54 and I think it’s the n55 that everyone wanted make sure to subscribe to follow along our build.

Downpipe/hpfp/tune .. 450-500whp. Don't waste money on intake lol.

Got my G30 540I can’t wait to tune it 💯

I say closed box air intake is better. Open like that sounds good but it was sucking in way too hot air and making the car run slow top end

I believe the ho difference is because the racha it’s manifold is different. The second gen b58 has six ports instead of two, making it better flowing.

My 2018 440i M Sport and I did all this. The car is faster than my 2009 M3 was

Thank you for the video. Would you be so kind to add links or at least names of the parts mentioned.

Ive been using bm3 on my iphone for almost 2 years

BMS only claims up to 8whp with their intake, not the 20 that you noted in the video - on a B58....The Dinan closed air intake in the best choice out there for a viable increase in whp

[leolopez]

I’ve heard a drop in filter is plenty for even high horsepower cars an open cone style can lead to heat soaking and loss of power after multiple pulls

[nickwhitesell]

wouldn’t it be more worth to get a closed box intake tho, if you’re just going for look and a little better sound, possibly go with the aFe?

I've never seen this episode of Two and a Half Men before, very Jake focused.

@5:10 - NA Cars dont need backpressure - they need exhaust scavanging just like turbo cars.
idk who set the roomer tho...

[dogdog]

20 whp from air intake??? In your dreams, maximal 5 hp OR - 5 HP

[emerytorres]

Depending on which 40i you have, the parts and prices will vary. I say under 2k

[mjam]

Cold intake no...standard air box is 100% more effective with a panel filter, you will actually lose power and get alot more heat soak with a cone filter. I know a guy in the UK running 700+ bhp with standard exhaust (just decat) and standard intake.

My M40i is already a rocket, I'll probably do this after warranty is up..lol

[See.M.Swervo]

Nobody talks about this but you have to do a DME bench unlock before you can tune… it’s $350

[joshborja]

Lol you don’t need a pc or Android to use bm3, they added MacBook and iPhone compatibility a long time ago.

Also the stock intake actually gives you better IAT’s meaning you won’t heat soak as quickly and you’ll have more consistent runs.

Instead of buying an intake I’d put that money into a TU pump (from 2nd gen B58) or get a better aftermarket HPFP. This will allow you to run a little more ethanol mix and make the opening bigger so your engine can get more out your turbo

I wonder how long it eill take for someone to do this with an Ineos Grenadier 🤔

3 years later, how has reliability held?
