LOLO
you said its ''Flat out''..?

RagingKileak · 04-23-2009, 05:19 PM

The whole reason I posted this question was to ponder the question of whether a replacement 200cell cat in conjunction with a good map and a straight through exhaust would yield a more sensible way to reach the 360 - 370 bhp whilst still within safe torque limits.

Also, there might be other benefits, like the way power is delivered, spool, back pressure...

Why do you want any cats? you dont need them. No cats straight through pipe with strong map then yes 370bhp is possible. Limit the torque to 700nm and your box will be fine.

Bigger intercooler wont go wrong either as you will be running over 2 bar of boost

Not quite as easy as that.

How exactly would you limit the torque when you are mapping to 370bhp? At 330-350bhp there is a slim possibility that the car will still be in the realms of 700Nm, but beyond that then it would take great mapping skills and a spikey map (not to mention a strange delivery) to hit an eventual peak of 370 without going over 700Nm.

Running a constant 370bhp + will cause issues whether it be gearbox, diff, drivetrain general, engine, cooling, turbo, fuel feed/pump and the first thing to go the many hoses/pipes.

Out of interest which "boost hose" failed on yours?

There are torque limiters in the map, these can be set accordingly. I agree it will take a bit more work to get it right.

My hose never failed. I had one of those cleaning days but heard a fully noise so on investigation I found the right hand hose hanging off.

It looks like it was poorly machined from the factory and been like that from new. I had to make the hole where the metal clip slides into bigger as the clip only just sat on top of the hose on one side. There was also a bit of machine swarf I had to remove so it fitted in correctly. My car only had 22k on the clock so hopefully not too much damage was done the the turbos.

I might want that, but I dont understand what it is - help us out Paapaa!

We can get that here with DPF in place

250kw is 335bhp

Yes you can but its not health, i think. Its all explained in Finnish,i am sorry but my english is not good enough to translate technical words :=D

http://www.turbotec.com/chiptuning/dpf.html

..something about pressure/backpressure and that you can get more hp on paper on dyno´s but its called "paperpower" and something that then its going to chunk the dpf....

i trust more for this tuning company which is speacialicest on BMW tuning and tuning since 1988 than any other information source.

lolololol · 05-24-2009, 05:03 AM

I have been reading this thread with interest,

Is it the forums view that a 335D can only be mapped to 350BHP 700NM safely ? Any further BHP is going to take some serious tinkering and of course serious money ?

When I was as Evolve they did tell me that they had a 360BHP map for the 335D but it was suggested not too use because of potential knock on issues.

I am surprised that the gearbox can even take 700nm of torque anyways !

M5 TT · 05-24-2009, 05:46 AM

That looks like a good read. Need to translate though

i used google to translate it. it states you can only safely tune torque up to 20%, after that the dpf clogs up too fast and starts building too high backpressue. think it also states a tuned software might no be able to regenerate it properly. I don't know, but rather then a boost gauge a back pressure gauge comes to mind...

M5 TT · 05-25-2009, 03:34 AM

It already has a back pressure gauge, well sort of, you could mabe tap into the DP gauge and work it out that way?

Allroad · 05-26-2009, 02:19 PM

Hi There,
I run a map that delivers 376hp/735 nm on the flywheel on my 535d, 2008. It was remapped on a Vtech dyno. On the wheels it was around 315 hp. Have been running remapped for about 5000 miles with about 1500 of them on Autobahn in Germany. No issues so far except nice speed. I believe the dyno numbers are about right: 0-62 in 5,5s. 0-200 km/h in 17,5s and top speed on Autobahn with gps was 274 km/h. The gearbox, ZF 6HP28 is specified for 700 nm so I'm not too worried.

How heavy are those fivers??? My puny 345bhp is getting me under 5 secs

neo871 · 05-27-2009, 06:05 AM

Is that really so Carl?!

Allroad · 05-27-2009, 02:57 PM

Your car is about 90 kg lighter. Do you have LSD? I do not have grip enough to make under 5s but are close if you check the video. 60 mph and up it is better grip so that is fast enough.

RagingKileak · 05-28-2009, 05:35 AM

There is a very good chance that Carl is lighter than any other driver too - no offence to anyone, he is just quite small/slight.

I weigh 105kg on my own, irrespective of car - so my 335d running a similar map to Carls, combined with my lack of driving skill usually takes me to 60 in about 5.5 - which is timed in rudimentary ways, but looks about right.
