401BHP BMW 430D! BIG Turbo, Intercooler, Downpipe + Remap! 

Some good ones!

Glad you enjoy it!

Absolute guzzlers

Everyone thinks the 335 is the one to have but I'd take either

30d rock machine 35d more powerful but not as reliable as 30d

Hi Ryan, yesterday I watched you get 400bhp from a 1.9tdi Skoda and today the same from a much bigger engine. My question is what is the limiting factor for these inline 6s ? Exhaust temp, rail pressure, injectors?

The amount of money spent in this case, bigger should mean more in most cases

Hi Ryan ,I have an f31 330 d wanting 400bhp so what did it cost for engine and gearbox tune

It was good, not V6 Audi but quieter when cruising

Yep :-)

chris8989 j hahah tes it was only you

Same

Yup thought that as well

NO! IT took me.ages to figure it.out

Only if you do the recommended oil interval(every 90k km a complete flush or every 30k km oil chnage in the pan) and not what bmw shit talk.

It's not just BMW, everyone that uses ZF does the same.

@@InfernoSRB that's true and kinda sad

@@withstyle7816 car life is 100k now. Even though with maintenance they could do 5 times that

Sorry, VAG and BMW only

Junior Junior I though they said in the video the solenoid injectors where better?

535 all day

As I commented above, the DPF is not a restriction at that stage unless it is getting blocks. Its worth just keeping an eye on backpressure

The injection timing is very complex and already usually where it needs to be

I don't Darkside do Honda's

Sorry VAG and BMW only

Send us the VIN via email and we can check - sales@darksidedevelopments.co.uk Thanks

4800rpm IIRC

335d with bigger turbo's might do a bit more.

Maybe not track use but certainly road!

Nope, ECU's are different!

Barnsley grimey.. i just checked LOL

550d turbo on the 330d? I think +20hp is possible with WMI on this car

Darkside Developments No, it is a gtb2260 based hybrid, much more capable then gtb2056 base. Thanks for the input, looking forward to install the WMI on my car. Next Dyno appointment is on 11.02. (this time dynojet).

@@mrlurchP11 Good Luck, I'm not a big fan of those dyno's!

Darkside Developments oh, you would prefer a superflow? The owner of the dynojet is critizing superflows, the owner of the superflow is critizing dynojet :D dont know what to believe. Good thing about this particular dynojet dyno: he has got some serious fan - he claims a run is possible up to 400 kmh (marketing bla). But here would a run in 7th gear possible, interesting torque wise.

@@ThenameisOskar Unfortunately I didnt installed the WMI kit und sent it back. It was a little bit to „hot“ for me to drive it on the street in germany approx 30.000 km a year.

Zf8 speed gearboxes need servicing every 60k miles

They all have their issues but BMW seem to have more!

50mpg, all f series 30d are solenoid.

Having seen dyno runs before and after on a different sedans diesel turbo i6, not really, back-pressure is exactly the same measured after the collector and power is within margin of error. On a turbo motor you want to maintain as little change in velocity (and as gradual change in velocity) between the head and the turbo, which means putting larger diameter collectors on isn't necessarily advantageous. Likewise its important for turbo cars to keep as much heat in the exhaust as possible, not only does any losses to the engine bay raise the under-bonnet temperatures, but as the exhaust gas cools in a constant diameter pipe it decelerates, which results in less energy turning your turbo for a given amount of back pressure (and thus less power/worse response). The factory cast manifold has less surface area than a tubular design, and its materiel/thickness provides more insulation than you'd expect (not as much as heat-wrap for sure, but more than lightweight tube) so its very good at keeping that heat in. It is also designed as two separate 3 cylinder collectors, not a simple log as it first appears, so interference between pulses isn't a big deal like it would be on a historic design. The rearmost collector merge angle looks terrible, but this is because BMW chose to make the total resistance (thus flow) of every cylinder the equal, and so the 90 degree bend does this much more space (thus heat loss) efficiently than a more intuitive equal length design. A naturally aspirated motor is a bit different because its desirable to try and extract energy from the exhaust. Towards this end a noticeably larger merge pipe than the collector tubes is used, and the inertia of the gas entering the larger pipe causes it to briefly pull a (relative) vacuum on the other collectors, which can help with scavenging at a particular rev range (thus volumetric efficiency and resulting power for a given temperature, assuming the motor can handle the increased combustion pressure). The important thing to remember is this isn't "better flow" its actually doing work with the exhaust gas, thus reducing the available energy for a turbo, thats just not a problem if you don't have one. All in all because they planned to make many thousand cars the OEM spend quite a lot of time optimizing, so even though they have a lower expected power and budget per part, don't automatically presume the stock parts to be inferior to aftermarket, very often while you can do better (especially when willing to make other compromise like noise) its not economical to re-invent the wheel, the same money on other systems like inter-cooler or high pressure pump can make far more difference to your power.

Turbine size IS ( dictates) your backpressure. If pipe is larger than turbine exit is useless.

I think there are gains to be made optimising the manifolds for flow and power rather than emissions, but these cars are packaged pretty tight, and the stock manifolds do just work, but it is a trade off between cost and reward. I don't think we will see massive gains so is it really worth it?

Hardcut can be any RPM you like. I can't see how it causes wear!

The Injectors seemed like the limit before the pump

I had a 15 and had issues but it's luck of the draw with any car!

400+vat usually

if they check it at the annual safety test then hollow out the middle of the dpf. Cat too. And ditch the egr. Then remap. If rwd add a lsd. But if no one ever inspects it in your state / city, do what you want.

We prefer diesel!

Diesels much more reliable if taken care of.

Please email sales@dark-side.co.uk

Likely less than 4s

Buying an exhaust or having one custom made will help with the sound and a with a good careful tune you can map out the majority of the smoke. We've had plenty of cars come in that have left with little to no smoking

@@DarksideDevelopments what’s the best for the exhaust ? straight pipe or something else ?

Straight pipe will definitely be the loudest, it just depends on how loud you are wanting it. If you drop an email to sales@darksidedevelopments.co.uk you'll be able to get a list of options that will suit you

And btw i am on the way on doing something similar saddly i am from mid europe but prolly gonna buy your downpipe package

I often make mistakes. We can sell you everything you need ;)

@@DarksideDevelopments i am going slowly, for now it’s on custom tune with 325 hp on stock internals. I am planning on lowering the car, fitting wheels, and then down pipe and maybe even a turbo cause with that performance you’ve shown it’s definitely worth it. But I wanna ask one more question if I can, is the reliability good even in those numbers ? And will the engine last ?

Look after it and it will last fine

The customer removed it

Typical diesel engines do not have a throttle valve. So the air fuel mixture varies all the time with a diesel depending on where the throttle pedal is at. So what you have to look at is fuel quantity as diesel engines always breathe more than they need.

@@MrAndrius12 i was asking that question because i see many modified diesel cars that leaves black smoke behind them like a semi truck

@@ristekostadinov2820 that is full throttle then. Straight piping could also help as some soot stays trapped in the catalytic converter and some in the muffler, so removing those two could increase smoke from the rear to an extent. Typically, from what I know of, anything richer than 18:1 is pretty noticeable (more-so on turbocharged engines).

Riste Kostadinov at idle Diesel will run at around 80:1 AFR and full load full throttle the engine will run at around 22:1 (if I’m not mistaken) to limit the amount of PM the engine produce. The typical Diesel engine can actually run at around 10:1 this leave you with huge room to increase stock power and some tuners can double the stock horsepower figure without even open the hood. But at this point you will have to face the high possibility of your piston turning from solid to liquid.

@@soraaoixxthebluesky I think you are forgetting about the efficiency of the burn. Anything richer than 18.5:1 is stupid.

These have Solenoid injectors so 550d parts won't fit. We have one in next week with bigger fuel system.

@@DarksideDevelopments ah damn it. I’ll be in touch soon for the kit listed in here. Shame I’m in the southwest otherwise I’d book it in with you.

People drive from all over to get a proper job!

I might take the drive from Norway, when things settle 😅

But can’t you change for the piezo injectors, the 2700 bar fuel rail pressure sensor, and 2500 bar fuel pressure regulator?

We seen a lot of varying power figures from the x45d engines, but with a FMIC and DPF Delete, close to the 400bhp mark is possible.

We normally see 220hp or so!

@@DarksideDevelopments curious, if any stage 2 packages are available and what the possible power gain would be? Thanks

Drop us an email and we will discuss! sales@darksidedevelopments.co.uk

Did a 330d at 424bhp and 660ft/lbs - www.darksidedevelopments.co.uk/bmw-e91-330d-n57-3-0-24v-cr-ga6hp-26z-6-speed-automatic-424-4bhp-660ft-lbs/ That was on stock fuel system as well so might be a bit more in it

It will. Seen n57 but in e9x body making 420-430 safe and 800nm. Stock injectors

They are all tuneable, but it is whether it is worth the effort spending 100s of hours in R&D for the size of the market. Our next target is the ZF8HP box in the BiTDI and new 3.0 V6 range

@@DarksideDevelopments that makes sense yeah.

Likely none!

@@DarksideDevelopments thanks for the answer! I have another question for you : How much do you think can be the difference in terms of power on this configuration between 76” free downpipe and 76” downpipe with kat 200cells?

Please drop us an email with your VIN and we can give you a full quote - sales@darksidedevelopments.co.uk

The bigger turbo will annoy you if you don't want the Auto to change down.

Email us please!

I’m emailing just now chaps, better late than never M

Drop us an email with the reg and we can advise on the mods we have available. The 123Ds are restricted by the stock turbo to not much more than a rempa power, although Intercooler makes a big difference. Thanks

Darkside Developments will do and how come they done that and is there any hybrid turbos, what intercooler could I bolt on and I was looking at the 335d coupe but dunno if I can afford the insurance so looked at the 123d

We summarise here on the video - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-7KpZtXUQXqk.html

You'd max the stock turbo at around 300bhp. Drop us an email for a quote - sales@darksidedevelopments.co.uk

Yes

@@DarksideDevelopments This is what i need. Sounds amazing

Our 335d remapped 380hp daily driving 38-42 mpg if you drive like a granny then easy 45-48 mpg

35d more powerful from the factory but not as reliable as 30d The 30d are normally better spec and you can still carry out these mods and achieve similar figures.

They are very similar, 435 has bigger boar pistons

@@england8754 they are not bigger

mazza v | Pwned. Stop waffling.

It allows the turbos to spool about 400rpm lower down if you emission delete dpf cat egr. Sharper response and huge improvement in fuel consumption. Top end is limited by injector and fuel pump flow. Around 380hp 550lbs torque.

We sure do

@@DarksideDevelopments E87 118d dpf delete?

This is a Darkside custom exhaust.

@@DarksideDevelopments Any chance u guys can make me one?

4.5 maybe on dry road?

@@DarksideDevelopments thanks mate! With the xdrive it would be similar to the A5 v2 i think. greetings from germany

Yeah the xHP does that. Cheers

The 335d will make 360-380 BHP with the stock hardware but we have no turbo upgrades for it, the 330d we have a GTD2873VZ turbo upgrade that can make 450 BHP with all the right modifications.

@@DarksideDevelopments with stock internals i suppose?

Yes but hard to get good ones!

@@DarksideDevelopments okay , maybe hybrid is better then. I have an m57 330d 06 plate , 221,000 miles on the clock. How much do you think it's worth roughly because of the engine? It's just an se , literally no optional extras. Manual gearbox.

Email us ;)

@@DarksideDevelopments will do.

Good careful tuning required.

No diesel road car needs to omit loads of smoke for maximum power, if it smokes the engine lacks the air flow. I have been building a compound charged fiesta 1.7L diesel using an M90 supercharger and a darkside gtd2872 turbo, I am expecting 370+hp of smokeless power.

The smoke you see out of tuned diesel cars is un-burned fuel from the cylinder and is instead burned in the exhaust. It's caused when the lambda reading is close to or less than 1.3. In order to gain more power from a diesel the lambda has to be below 1.3 which is where you get exponential smoke pouring out. To get the absolute max power out of a diesel the lambda reading has to be close to 0.85 but at that point you'll be putting soot into the engine oil, a lot of diesel in the engine oil not to mention the amount of carbon deposits coming out of the exhaust BUT NOx readings would be low. As Ryan has said, careful tuning is required to borderline between max power and un-burnt fuel.

Humza Ahmed i got the c220 om651 engine, remapped it last week to around 200hp and 500nm. From 170-400. I hit 240 on the autobahn today :) But to be honest if you want more power it might be better to go for the 350! Will be my next also
