Kern, I did pure 800 swap over the last 2 weeks (first thing I’ve ever done on a car besides a cat back) and you and kies are the only reason it happened, thank you. 😁

[@smexypookie1862]

Axle back* not cat back lol

[@chrisginoc]

​@@smexypookie1862catback exhaust isn't the proper term?

[@kern417]

Catback and axle back are two different things. If he only did an axle back then catback isn't the right term

[@smexypookie1862]

@@chrisginoc yes I what I meant was axleback on my e46 M3 lol sorry for the confusion.

[@HassanEido1]

Solid turbo. We did a full year of testing on these units at 36 psi.

[@Alex-i176]

Have you tested the ultra flow?

[@HassanEido1]

@@Alex-i176 tested and tuned all daw turbos. What do you need to know

[@Alex-i176]

Just how far I can push it safely not trying reach its limits but just getting pretty close, I am installing a ultra flow with injectors just never really seen any opinions on the ultra flow only flow max +

[@HassanEido1]

@Alex-i176 ultra flow usually ships with race thrust bearing, I drove the uf for 6 months with more than 36 psi . It was a very solid turbo. Got beat on several times a day, only driven hard. Made 732whp on the old ultra flow, pretty damn good if you ask me

[@bartsal8312]

@@HassanEido1 what is the ultra flow x like compared to flowmax v2.5+?

[@agxnt7649]

I got a 435i a bit ago and now I regret being a cheapo and not buying a b58. I already spent extra fixing issues that could’ve been spent on a 440i. :/ the b58 sounds so much more reliable and looks easy to make big power. Turbo upgrades on n55s require wayyy too much work to just do it in a garage like this. You live and you learn I guess.

[@chrisrstt]

I got a m340 and honestly I just run it stock. I got mhd and xhp purchased but I don’t use it. I rather just keep stock reliably. I don’t care about being the fastest because I know there is always someone faster. Enjoy the car for what it is

[@elijahlane411]

They both have their pros and cons, is the b58 better? Yes, but the N55 is still a great engine you can get 500whp very reliably just as easily as a b58. You'll never be happy if you don't love what ya got brotha

[@agxnt7649]

​@@elijahlane411 I can't think of a single n55 pro over the b58 besides it being slightly cheaper. Yea you can hit 500 hp with a n55 but it does require a whole lot more work and you're definitely pushing it. I still def love my 435i but I be watching so much b58 content bc thats whats being uploaded lol

[@SubOhmN8]

Very informative, helpful videos, Kern. Your B58 is straight fire, sir.

[@haetfull]

Love how detailed all your videos are, ad that you show every bolt.

[@Cameupoffa2]

Thanks for this video man. There arent a lot of install videos like the ones that you put out. From the quality to just the humor. Appreciate you brother🫡 Shoutout Kern 💯

[@MistakenMedia087]

Moved my sleds out of my garage to storage today, got a flowmax+ ready to install on my gen 1, the timing is good for this video.

[@Potam94971]

Happy to see this built . I do hesitate between ultraflow version and turbo systems stage 3 rated for 700 crank hp I saw some stage 2 turbo system ran 100-200 under 5 sec and run 1/4 in 10.00s I will wait your feedback Thanks

[@hasan_440i]

Great numbers!! Have u installed PI or upgraded injectors?

[@kern417]

i am not going to be going for records with this turbo so this isn't the place to get that info. but i will share results for daily driving and track duty when i head to the road course this summer.

[@lokionarma3645]

Will be super interesting to see what you get out of this on a conservative track tune with Less backpressure in the exhaust housing/exhaust manifod and the newer higher flowing 76mm inlet. I am curious what your WGDC numbers will look like on higher levels of boost versus my Ultraflow set-up. May want to consider some enlargment of the exhaust after the downpipe to keep the flow rates up there. Add all this new stuff to the fact that Shawn is going to start offering T51R mods on the DAW turbos in the spring and it's a great time to be a DAW customer!

[@simonespeed]

#6 dme connector , nice hack. Thanks!!

[@MrInvisible2you]

Thank you for doing thiss!

[@day4061]

I have the same one. Trying to install it now but the oil line at the bottom of the turbo is a pain. I was also told this turbo will be better than the last generation UF.

[@adamkiracofe8602]

Great video! I know Shawn and the crew at DAW are probably cringing every time you refer to their turbos as "hybrids" 😂 Dont get me wrong, I love my DAW UF.

[@YKxNemesis]

Just letting you know my exhaust flange nuts came out with the studs when I removed my turbo. I ended up researching about it online, the advice I got was when you re-screw the studs back in the with nut on it apply a bit of threadlocker and hand tighten it back on. If you guys have a better method let me know but this is what I was recommended just thought I’d share what I ended up doing.

[@kern417]

They screw in and out pretty easily and can be replaced. I probably wouldn't use threadlocker so i don't risk snapping them.

[@mikew4796]

Great video! Can't wait to see it in action.

[@Conservator.]

16:40 New mind has an interesting video on the development of head gaskets.

[@Bitaliktderr]

Any chance we get a before and after exhaust sound clips from stock turbo and upgraded?

[@DarylSantos_B58]

Been waiting for this video, I still want to hear more about the turbo how it runs and what’s the max hp capacity.

[@kern417]

will be sharing that and more in the upcoming weeks

[@behindthebuild8016]

As someone who had the flowmax then went to the ultraflow I think you’ll regret not going ultraflow from the get go even though you probably got the turbo for free from Shawn 😅

[@kern417]

this will be perfect for my goals

[@chriskamen2152]

So I got a FlowMax withe the UF compressor wheel and race thrust assembly right before this came out? which one do you think spools faster? Shawn told me the v2.5+(UF) is still faster, but idk

[@WhiteBeardDetail]

Thats me in the intro! Chin up cuzzzzz

[@Conservator.]

11:22 “With bigger … [everything] … it will allow it to spool up quickly” Genuine question: with larger ports and the same amount of exhaust gas and a bigger turbo, wouldn’t it spool up less quickly? The airspeed would be lower wouldn’t it? I understand that the top end will improve but I don’t understand how it wil spool up faster. I think that’s why we have variable geometry turbos that will mimic a small turbo at low rpm and change to a large one at high rpm. I’m just an armchair ‘expert’ so please correct me if/where I’m wrong. Tia!

[@behindthebuild8016]

That’s correct. I think they’re saying it’s larger meaning more that it will flow better than oem hence spool well for a larger setup

[@kern417]

spool is based on a lot of factors. higher flowing turbo needs a higher flowing exhaust housing and manifold to run efficiently. if you run to big of a turbo with too small of a housing, it will hurt flow. this is one of the biggest issues with hybrid turbos that simply reuse the stock exhaust manifold. this is the same reason a bigger intake can flow more air.

[@Conservator.]

@@kern417 Ok, Now I see what you meant. Thanks!

@Kerm417 So with the troubles are you still happy with your DAY Ultra Flow X? Can't decide if I wnt Ultra Flow or 6466/6769..... Any feedback would be much appreciated

Yes it works great

@kern417 which DAW turbo is it? It’s not listed as “next gen”. Greetings from Holland!

[@kern417]

it is a new unit that is not released yet.

I want to delete pcv on my M240i gen 1. Do you recommend the ross racing V1 kit ? Just the hose from pcv? Without catch tank? Is it enough to dont worry about pcv failure again ?

yes. yes. yes.

@@kern417thank you.

[@Angel-cv3cr]

Pure 800 or DAW ultraflow x?

[@Angel-cv3cr]

?

[@johnl.38]

I was thinking of going this direction with the DAW for running pump gas on a b58tu. Do you think the zf8 would need building at these levels? (91/93 octane)

[@hasan_440i]

Limit the torque and you will be fine

[@behindthebuild8016]

On pump gas only you’ll be fine with any upgraded turbo as the torque won’t be there until you add meth or ethanol

[@kern417]

i'm staying stock trans as well so my results will show how it handles it at moderate levels

[@chriskamen2152]

I just got a v2.5+ from MRM with an ultra flow compressor wheel. Should I return it???

[@behindthebuild8016]

If u can 100% new one comes out in 2 weeks

[@WhiteBeardDetail]

​@behindthebuild8016 where did you find the eta on the new daw turbos ? They have like 3 new ones coming out???

[@ir655]

Can I use TU pump with this turbo or do I need to go better than TU HPFP?

[@kern417]

any fuel setup can work. it just depends on your goals. plan out what you want, and then buy supporting mods to support what you want.

[@ChristopherSantos-wn4sg]

Can we get an exact link for this turbo? Is it the Ultraflow or the MAX V2.5+ ? Or is it a new one that hasnt come out yet?

[@behindthebuild8016]

In the last video he said it’s the flowmax but with the new housing that comes out in 2 weeks

[@kern417]

when it comes out i will post a link. for now it's still in testing

[@joshuamolina2986]

What could happen if you don’t replace the down pipe gasket lol

[@kern417]

i doubt it. most plastic parts are made like that to save money but retain structural integrity. look at the intake manifold for example.

How many hp on your car with regular fuel? Without ethanol etc
