Sorry but I'm new here, after purchasing my 335d I would like to know what I can do to get lots of power? I know remap and dpf delete etc.

I would just like to know what you have done to yours and what power it has, also how much of a difference it is?

What problems does it cause by having more power etc? (If any)

And what have you come up against beat/lost (obviously on closed private road/track)

Coming out of my e46 m3, I feel that just had the edge over the 335d.

Anyway take it easy remember I'm new here and this is my first post.

Pushing more power on a tune will cause Coils and plugs to fail alot quicker. As in replacing every 30k miles for safety.

[MrPig]

On the d, more power = more torque and it's already pushing a lot of it. The transmission may not be able to handle it.


Also, you'll be replacing your tires a lot more often. Wink wink.

No such thing on a D

however the tranny is rated for 600Lbs torque, 400BHP out of a 335D will push torque in the 750-800 lbs I believe but don't quote me on the numbers.

If the car is out of warranty look into eliminating the EGR ( either code/tune it out) in order to avoid gunking up the intake manifold and valves, also eliminate the intake flaps that could potentially grenade the engine if the 2 screws holding the flap to the shaft work their way loose.

Good Luck and tear that asphalt up!

Cheers buddy, no warranty, swirl flaps already blocked off and will be doing egr at a later stage.

There are a lot more postings in the diesel sub-forum.

But 400 HP is on the far end, and will require more than just a tune. TDIWise has one of the most modified ones (dpf delete, egr block, ecotune with custom stuff, scr delete, meth), he recently hit a 11.8 @ 120 mph quarter mile. His main problem is TOO MUCH TORQUE that his LSD and drag slicks don't solve and tirespin is limiting his launch ...

That's what I was wondering could a lsd actually get the power down? how do i look at the forum? What's a safe amount of power what I could actually use?

I have 380bhp And 600 ft lbs with a quaife LSD. See signature for complete mods list. Under 5 secs to 60 and 100 in around 10.5 secs. It's a real blast for sure and I still have cats and DPF

[Ajs_435d]

Hello Tom

I will say I absolutely guarantee you wont get 380 with just a remap on an accurate dyno (in UK dyno's), just not possible (remap is circa 340/350) I got friendly with Stan at ecotune and I've looked at many many graphs before and after, the D's that come in range from 280-290 ish, if its evolve or DMS figures i can well believe it

Before on mine bog standard 284, after 372/565 with remap+DPF removal EGR delete and air guides.

I dont think 400 is possible really, you'll get damn close though, i recall a D with remap, DPF delete, EGR off and Wagner IC it made ~386.

If you added meth you might just might hit 400 .

As above tranny is rated for 600LB torque after that your pushing it really, but you have a different diff which is good.

You joking you D will destroy a e46 M3.

I havent had a go against many cars, but left a remapped FOCUS RS, and 08 plate subaru WRX STI comfortable.

Awesome car!, i get 35MPG too but drive economically.

That is good power with still having cats and dpf.
Under 5 0-60 I like the sound of that.
Have you come up against anything good and beaten it?

[tomwh85]

I've spoken to ecotune and that's my preferred tuner which I'll probably be using, they said to reach 400+ I'd have to get hybrid turbos which I've not really heard of anyone doing this apart from a couple of people one being on here.
I'd like to get 380, I'd be happy with that, so I'll have to get fmic, exhaust, filter, egr blanked, dpf deleted and remap.
When I bought it me and my brother had a play I was in my m3 both similar drivers but the m3 had the edge but It wasn't easy, I raced my mate who bought it off me and I beat him so it's down to who's driving really.

How does meth work?

[Stu In Blackpool]

580ftlb and 360bhp is about the sensible limit with DPF still in place.
The torque limitation is the gearbox. I've never heard of one actually die but your pushing your luck beyond there as ZF Have a different box for 700nm+

The horsepower is limited by the flow of the DPF and the way this exhaust restriction affects the thermal limits.
Most tuners actually code out the limp home torque limiter so this thermal limit doesn't affect performance but this is a BAD way to tune. There are a lot of cars out there with the DPF temp sensor error flagged and the vehicle is actually operating in limited operation mode but it's not noticeable by the driver as some idiot removed the huge and very noticeable 3800rpm torque limit.

Always worth asking your tuner what his AFR curve looks like and what his personal max limit for EGT is with these turbos. You would be surprised at the answers you get, I promise you. Lol

[Ajs_435d]

Why do you want to monitor AFR in a diesel its not a figure that is that useful in a diesel (due to the massive range) than it is in a petrol because of the range and the fact there is no TB on a diesel.

I see what your saying about the temp flagging, this would/should be altered in compensation tables?

We all know EGTS will be lower with a DPF removed due to dwell time, which is another good reason to remove the DPF.

AFR is just as important in a diesel as it is on a petrol engine mate. I'm heading to bed as little one will be up at 5:30 no doubt but if your not so sleepy, do a little googling on diesel AFR and the relationship between economy, smoke and temperature you will see that all the so called "tuners" who throw in plenty of diesel and quote "no poke without smoke" really don't understand what they are doing and are a major cause of clogging up DPF's, inlets and EGR systems.

Jeeps, I spoke to one very well known tuner last month who told me they get their target power figures and then add 5% extra diesel just to KEEP THINGS COOL!! Scary stuff. Lol

Yes, the thermal limitations in the ecu can be moved / increased easily if you have the a2l to understand the firmware, but the fact is, there are a lot of components that don't like excess temperatures we are talking about and that is why the limit exists... To protect your engine. In most cases, the manufacturer and designer really do know best and their limits should be adhered to. Thermal limits are one such subject.

400hp barrier is no problem nowadays. My car broke that mark 2.5 years ago with stock turbos.

About gearbox, there are already several stuff for it. Exedy clucth pack st2 eliminates the slippage issue to levels beyond 1000rwtq and there is a buch of companies with billet input and intermediate shafts to increase gearbox strenght.

If i had enough time i think that these days the 500hp mark is possible. There is out there available new turbos and fuel solutions for that.

My coils and plugs weren't accomplishing anything, so BMW omitted them on the assembly line. Car seems to run just fine without them.

Nobody said breaking 400bhp was a problem? What I have highlighted in my posts is the limitations whilst retaining sensible EGT's with emissions hardware still in place and that is catagorically around 360bhp.

My quoted torque limit was for the Autobox that 99.9% of people dont want to be trying to upgrade...

With dpf still in place i believe that 360-370hp is the max you can get with reliable in mind. I know a guy that made 424hp just with software but his car was only able to pull for short runs due to insane egt's and easily clogged dpf.

I'm not so sure about gearbox mods. I believe that you only think that way because there isn't a house in europe willing to deal with that, which i find funny because here is where you can find more cars fitted with the ZF6HP26 (BMW, Jaguar, Rolls Royce, Bentley, Maserati, Audi, Land Rover, Kia, Hyundai)...

In the Australia this is a popular mod, AFAIK, the only place in the world where you can find +1000rwhp cars making 8's and 9's on 1/4 mile with the same gearboxes. They even craked the gearbox software for custom tunes.

With the shaft being around $2000 and the clutch pack around $600, i don't think that is that high for those that are looking for +450hp. At 400hp level, stock gearbox is more than capable for the task.

[Puerto Rican 335d]

Like tom stated and Stan I strongly believe a larger TURBO can achieve this , Stan has done wonders about our cars if anyone can speak about them would be him I beleive. Good luck in your endevours

[Bicax]

Damn you all and you conversations about 400hp!

I just ordered a Wagner IC and will push for a DPF delete and a remap as soon as it gets here.

I'm actually going to Portugal for two weeks relatively soon and I'm tempted to even do the turbo upgrade, but I'll refrain from it for now. Otherwise what is there to look for in the future, right?
