Fabricating a 3" Maf for our Volvo 940 Drift Project

Fabricating a 3" Maf for the Volvo 940 Drift Project
Part 2
Welcome back to our channel! In this video we will be making a 3 inch maf pipe to allow more air into the turbo for our volvo 940 turbo drift project, We have got some milling and ally tig welding to get this fabricated.

Beth has some mad welding skills.

[@vintagedashboard6810]

The best past is the sarcasm but still you 2 have one of my favorite KZbin channels I watch.

[@fixitnige]

Hi guys sorry been so busy working on my ute I missed your vid's so will watch all and catch up great work :)

[@michaelskinner896]

Nice welding!

[@schalkvandermerwe4160]

Those welds tho’ 👌

[@robertreynolds9228]

Fair play to ya. Brilliant job on the welding i say. Dad pretty chuffed on that right 😃 have a great day.

[@pauljenkins2501]

Another excellent video. Thank you, both of you. As someone who is utterly rubbish at DIY and fabrication of any sort, I really admire your work.

[@neila2953]

Great video, looking forward to more Volvo content. Might just get me motivated to finish mine. Hope your are both well, stay safe

[@stephenwevans]

I find this very satisfying. Probably because I always wanted to be able to fab stuff like this. Thanks for sharing!

[@dj_paultuk7052]

Just to note, with Bosch LH, you cannot just go fitting a larger intake pipe. Since you have now enlarged the total volume of the air intake system. So the programmed values in the ECU are no longer applicable. Consequently it will run like crap. I know, ive been through this pain with LH and had to revert back to stock piping. Problem is, no one is able to remap LH anymore, or at least i could not find anyone. So if aiming for more power then you need to look at aftermarket ECU systems. Or in my case i fitted Saab Trionic 5, which is now opensource with T5Suite and you can map away to your hearts content....

[@usherengineering179]

Hi i can see what you're saying, that is interesting, the car seem to be running fine and not to different to the original stock pipe but we are still experimenting at the moment...i will bear that in mind if we get any running issues, thanks for the info!

[@MrVein5.0]

@@usherengineering179 in sweden we have a online store called Kl racing, they have Chips for volvos LH2.4 pre tuned for 3"lmm, 19t or similar and 465cc injectors, both fuel and ignition for the very low price of 150£. there is also BSR that have kits but way more expensive. vikingship and timos moto is no longer available i think

[@bullaniugnen]

Came here to post this, the ECU needs a different tune to use the 3" MAF correctly but there are loads of people capable of remapping the LH2.4 ECUs, all you need is chipburner or an Ostrich chip emulator if you want to do it real fancy like. There is also alot of readily available info on the LH system, MAP dumps from nearly every version and I'm pretty sure I found the MAF curve for the 3" MAF somewhere (early 960 with the 3.0 engines came with LH and 3" MAFs stock, presumably it was dumped from one of those) so technically you could just get a MAP dump for the version you have along with the correct XDF for tunerpro, overwrite the stock MAF curve with the 3" one and then burn the chip. But as MrVein already mentioned, there are also ready chips available that come preconfigured for use with bigger MAF, injectors and turbo, these usually also come with a retuned ignition as the stock one likes to knock on higher boost levels, seen these type of chips available on ebay and alot of swedish sites. Another tip that's MAF related, when upgrading the turbo, try to make the new intake pipe from the MAF to the turbo inlet roughly the same length and have it turn approx. 90degress just like the stock one, these MAFs are pretty sensitive to turbulence from the compressor wheel and atleast on my 940 where I had only a 45deg bend between the MAF and turbo, I got horrible idle for a few seconds after every pull, sometimes the car would just stall directly after lifting my foot of the pedal. This was remedied by putting a 90deg silicone bend inplace of the 45deg one. Also love the fab work, it's really interesting to see how others solve these things as I have made quite a few of these myself but went about it pretty differently.

[@Erd_Geschoss]

@@usherengineering179 Just get an Moates Ostrich and you can do it yourself, even with live tuneability. I run 2bars boost on ethanol fuel with 3" MAF and 1000cc injectors with the ostrich on original LH2.4. No problem for over 100.000km (related to this :-P) www.moates.net/ostrich-20-the-new-breed-p-169.html and forums.turbobricks.com/showthread.php?t=227153

[@SiebenSX]

That was my first thought too. The diameter of the MAF is a fixed value for the ECU. If this is changed, the software must be remapped so the car knows again how much air its getting. Otherwise it could run too lean and the engine could be damaged.

[@Marks-Garage]

Would love to be able to fabricate to that level. Half the battle is having the brain to figure out the best way to do it😂. Engineering skills are rare in the UK so it's great to see people with an interest 👍

[@carl_marks1626]

Well designed and built. Nowt like doing it yourself. The last one I did, I made a cold air box behind the grill with a 20 inch Laminar pipe in between.

[@danielhillier7417]

Nice to see my old Volvo coming along.

[@chemistry636]

Another very interesting video to watch. Its great to see problem solving. Looking forward to more videos with the volvo.

[@carlsiddorn3340]

Fantastic 👏

[@MartinMcMartin]

Parenting done right 👍👍

[@AW-Services]

Yes another new video. Hope you are both well Love the adapt and overcome ethos Keep up the great work

[@ShedTV]

I can't even stick steel together without the welds looking like a mad man's arse; never mind ally! You two make it all seem so easy.

[@finlay230]

Great update folks, channels commin on great 👌👍

[@buddybonus10]

Beautiful welding❤️👌

[@georgetouzis6103]

Another really good video. I enjoy watching you and your dad work together. As a Canadian, I enjoy listening to your English accent. Regards from an old retired tech from Canada 🇨🇦

[@MaxCotton]

You do an amazing job. 😍

[@mrjuergensie]

hey what a phantastic video, pls more of that content 👌

[@benthompson1254]

Love watching you work. You are very talented.

[@benrage5373]

Looks great nice job guys and nice welding 😍

[@andyep3103]

That’s Impressive! That engine bay was pretty clean too !

[@MrVein5.0]

nice i like this! I actually done the same operation, this was way more serious than the one i did tho, i literally just cut a hole in a 3" pipe and glued the MAF guts straight to it. Looked like shit but worked fine, this was together with bigger turbo and IC, Bosch 044 pump, bigger injectors and other fuel and ignition MAP.

[@joewilson413]

Bigger maf intake. The air will pass through slower. More air at a slower speed. it will run lean.

[@usherengineering179]

Next to fit is a larger turbo and bigger injectors to up the fuel then we can check the fuel on a rolling road

[@7433074330]

👍👍👍👍👍👍👍👍👍👍👍

[@daandrews71]

I love your videos but I had no idea what a maf is 😂 but you are both inspirational 👍🏼

[@7eis]

Another job TIGd of the list📃✅

[@petedoherty6041]

Keep up the great work a bigger inter cooler will help as well

[@pjs617]

Great piece of work 👍👌 just trying to think of something on my VRS that would look nice all shiny that I could commission you to make for me 🤔 love the videos and your work

[@ToreDL87]

Good work, but the Volvo's dont need this level of work done to them to be a good drift car. Weld the diff, shorten the steering arms/knuckles, chop the springs, and off you go ^^

[@winandd8649]

Did you alter the computer in any way to do this? The sensor now thinks there's the same amount of air passing through, but the pipe is much bigger, so in reality, much more air is coming in..

[@beluxauto5968]

Like I saw , who used the file in the end ? Always nice to see some content of you two .

[@usherengineering179]

She did🤣

[@barrybritcher]

couldnt you just use 2x 3" silicone couplers to put it in-line?

[@thatdudeinorange2297]

So.. was it a year ago you had 1000 subscribers? And now another 30k+ added to that, wow!

[@kosef5568]

Do you think you’d have anymore in stock at any point?

[@liten48]

wonder what happened to the escort

[@usherengineering179]

We are hoping to get a new video up on the Escort soon, we have been incredibly busy over lockdown that it got put on the back burner a little bit, but we are soon going to be ready to fit the cage!
