Chef's E39 530d

[Ralf*]

I was (possibly still am slightly on Osiris's line of thinking)

Before wading into this debate, I thought I would do some research myself

http://www.myturbodiesel.com/wiki/turbocharger-vnt-and-diesel-turbo-faq/

the above link has a lot of info, especiallt the portion of how good a downpipe is for reducing unwanted back pressure etc...beter power etc.

but my thinking is still that the level of mechanical reliability of the turbo has been reduced.

many years ago when I was an "appy" there were two distinct groups of appy's, ...those that believed that the "slide-rule" engineers had spent enough time designing the BEST compromise of power/fuel-efficiency and reliability vs ...another group of appy's that always knew better than the designers and engineers, and they proceeded to do all sorts of mods and enhancements to the likes of Ford Escort MK1's, Cortina's etc

invariably the appy's that "made their engine WARM" suffered catastophic failures along the way somewhere, and those that believed that the design engineers had done thier job properly, had "old-faithfull" and reliable motoring.

In CHefDJ's case, if he were to treat his car with care and drive it the same way or more carefully, then these mods might be just the right thing for further preserving the life of the turbo, ...but...should he now decide to make use of the power gains and turbo responsiveness above those officiailly designed by BMW designers/metalurgists etc then I believe it is a big leap of faith to believe that the turbo will be as reliable as before the modifications were done.

These are just my thoughts (sitting on the fence)

I like pie.

Well this is entertaining :fencelook:

I must just add this.

:idea:

I don't care if you turbo blows up in 3 minutes or 30 years, your car sounds epic!

This weekend was the first time I sat and drove a tuned diesel....I'm quite in love with the engine and exhaust tone. ....and now....and after hearing yours, I'm starting to view tuned diesels in a different light. Keep it up bud...

To be perfectly honest I think the most likely.part to break would.be the auto gearbox

Dude calm down no one here is out to go you or has a problem with you. Your theory on the turbo over spooling was just wrong. Am I not at liberty to say so?

If you can't have a constructive debate then it's probably best you don't participate. I'm sure everyone who has commented here is well aware the cost you incurred.

I do not know you and I do not know how you drive. Did you happen to see the question marks at the end of each sentence. I was merely asking to get an idea of your driving style. Don't just jump to conclusions. As you also do not know me.

And again I'm not "bashing" you but these cars don't have electronically controlled turbos. As my understanding goes. The more fuel you provide the higher your turbo boosts. So I don't think what you have said about the turbo boosting is correct as it's not controlled directly by the map. All that will happen is your turbo will run cooler with the untweeked map and spool a little quicker. I think 2 to 3 times quicker is a bit optimistic. Also why I think that is wrong is because I've been running a DP and decat in the mid pipes on a stock car for a good while now. And it would be the same ideology as you applied to your untweeked map.

Again I am not bashing you. The forum is here for sharing and constructive debate.

Take it how you will but if it's the wrong way then rather don't comment.

so im not the only one that call you an internet genius :roflol: but I agree on your statement again:thumbs: the turbo will boost higher if it is mapped for it, other than that it will just spool up and down faster with less resistance which is good and expelling exhaust gasses faster. :idea:

[Fuzz@tinyNET]

:roflol: this thread though

If what is being 'argued' here really held any truth, why are there so many 'modded' cars being driven around without major / catastrophic failures happening?

Further to that, I see aftermarket, dealer approved mods being fitted to cars, and they seem fine too - again if the argument here is correct, there would be no chance in hell where these mods would be approved.

Osiris - the common thread in your essays here pokes blame at everything / everyone else besides yourself. If I paid a decent amount of money for mods (assuming that you did), I'd want to know everything about my car, and also have a direct input on how aggressive my mods and tune is. I mean I've seen your car going sideways around the Kyalami area before, so if you're claiming the saintly route here, then I'm not sure...

We understand that what you went through was a pretty rough ride, but before claiming that everything is all rubbish, you should perhaps enhance your knowledge with solid facts, as the guys on here have done.

Take my advice, don't take my advice, I really don't care, but your 'theories' bring you into disrepute and ridicule.

 

[S1NGH 911]

God every time I say something on this forum everyone jumps on it as If I have said something evil. calm your selves and maybe learn from other peoples mistakes.

Here are the facts:

A: BMW designed the perfect exhaust system for your car that works, makes the car last long, I know this because when I tried to make my exhaust sound stock again, no exhaust fitment place could get it right. So BMW 1 other exhaust fitment centres 0....BMW creates beautiful cars with beautiful designs with outstanding technology and you think some exhaust fitment center has more knowledge than the scientists and engineers who work for BMW? Do you think that because an exhaust sounds better or makes you gain a few KW that its better? Please think again. BMW make formula 1 cars and the best super bike on the road today, I think they know what they are doing.

B: When you put software and do exhaust mods its because you mainly want the car to go faster, the sound it produces makes you want to drive faster to hear the tone and to get the addictive feeling of torque thus the life of your turbo...engine..tires etc go to shit! 20k km in the grand scheme of things is Nothing in terms of the life of a bmw, a stock standard bmw that has been looked after will do half a million km and carry on ticking no problems. My volvo I am currently driving has done 260 000km with the stock exhaust, stock cats, stock turbo, none of these things have ever been replaced and the car still drives extreamly well....My 330d was driving just fine, I modded the ******* **** out of it, software, downpipes, decats, removal of back boxes, and many other mods here and there and the car lasted a few thousand km and then **** up in a huge way! turbos exploded, gearbox exploded, injectors I hear have now been replaced and yet another turbo and engine has had to be taken apart. NONE of that would have happened if the car was left as stock and that's a fact! so please don't try and preach that modding a car is healthier because most modded cars half there life spans or even less.

I do not come on here to tell you advice because I am arrogant or think that I know it all, I come on here and type a long email like that out because I have had personal experience of this crap, I have spent bucket loads of cash fixing the fuck ups afterwards. Its not because of software alone its because of a whole fuck ton of things together that cause cars to go boom! When my turbo exploded, my car got towed to BMW for a diagnostics, they blamed the exhaust, I then took it too my mechanic who checked it out and also suspected the exhaust but said it could be anything who knows he would have to send it off for proper assessment. He then removed the ****** turbo and sent it off to Turbo SA or what ever the effing place was called, I will try find the receipt for a full proper diagnoses to find out what exactly caused my turbo to literally explode, they then asked me what mods I had done to the car and I told them and they then told me that it sounds to them like I had too little back pressure and that mixed with my driving and other mods caused the turbo to get extremely hot to often and the turbine blades to expand and touch the sides and cause a catastrophic disaster. Fact: something that would never have happened had I left the car stock! (How do I know this you ask, well when the car was stock, the turbo was silent, it wasn't even audible! car drove smoothly, smoked very little in comparison to after my mods, but then I did all my mods and my turbo suddenly sounded like a ******* F16 fighter jet, started making massive dumping sounds which I thought was all good and healthy, Boy was I wrong!).
You guys seem to think I come on here and suck **** out of my thumb, what the hell lol, I have experienced this crap first hand, and paid the price, I never said oi your going to **** your car up, I merely gave a word of caution to just listen if the sound of your turbo starts to change as mine did after all my exhaust mods!

Yes I did drive my car hard every now and then, who the hell buys a fast car and mods it and then drives it like a bloody granny? That would be like buying an R1 and never riding it fast? its a stupid mentality.

If a guy comes on to a thread I have made after I have done a mod and has had personal experience with something going wrong I would personally thank him and listen to what he says or at least take his advice. Its frikken unbelievable that when someone tries to give advice that they get bashed for it.

These forums are made for sharing of knowledge, showing off cars and mods and most importantly for learning something. I sure as hell have. I thought I was smart doing all these mods on my 330d and I was warned that it will lead to the destruction of my gearbox, I was arrogant and said my gearbox is strong! and in the end I was the doos sitting in South Coast with a very fucking expensive problem and no way to get home because my tow truck driver wanted to charge me over 12k, BMW wanted 85k to fix my car and gizmo was in joburg! Luckily Andy helped me out to get to jhb and in the end his car got fucked up and my car got fucked up some more and it was just a shit experience in the end for everyone involved! So why bash me when all I am doing is giving some good advice that could save you allot of money if something were to start going pear shaped?

By the way this is not to say that I wouldn't mod my next car I buy again because rest assure I would! I would do software etc but because of my stupid mistakes I have now learned a few things and will next time listen to what others have to say and do a hell of allot more research so as to not make the same dumb mistakes again that I am still paying for today!

You're obviously clueless as to what goes into modding and keeping a car healthy :biglol:

 

[Andy1GP]

With all due respect I "too many cooks spoil the broth" comes to mind with that particular 330d. Nick only wanted the best for his car but I feel too many parties involved caused a serious chain of events that led to the car becoming a money pit.

 

[Nikhil]

Chef I think you should lock the thread now :roflol:

 

[osiris]

LOL the way you guys think this is a joke is funny as shit. Laughing at other peoples mishaps is exactly what annoys me about this forum.

I have seen this type of thing so many times, when ever some type of mod goes wrong the person who paid for the mod is to blame and he or she was driving badly etc etc, I never blamed the people who did my exhaust as they did what I asked them to do, I never blamed the guys who did my software as they loaded software like I asked them to do. I never blamed the place that did my down pipe or decat, they did what I paid them to do. I just told you guys how it all went wrong in the end.

Yes I already stated that from time to time I had fun with my car, people buy 335i 135i M3's M5's and take them sideways around a corner or put foot in them from time to time, while those cars are stock you could do that allot and the car will survive. in my case I paid good money to do mods and my car destroyed itself in every way after the mods.

If this is wrong info and I am ridiculing myself and making a fool of myself then I this is very funny. Like I said I spent allot of money to repair and find out why things broke and I got my info...It was due to my mods and I didn't get cheap mods by any means. I paid allot for them and shit went wrong. That's that take it or leave it and laugh all you want I for one don't find it that funny but rest assure that when one of you come on here and tell of your blown turbo or broken gearbox I will laugh at you and remind you of this thread. This is so childish that a bunch of grown ups can laugh at a guy who came onto a thread and said be cautious with your current mod because this is what happened to me. You take offense, you laugh and carry on like a bunch of children and I just don't understand why?





I never said thats a shit mod your an idiot your car is going to blow the **** up I just said monitor your turbo after doing all these things. WTF was so wrong with that?

 

[RAArmstrong]

[DieselFan]

I for one never ridiculed you. I just explained why your theories were wrong and what in my opinion was to blame and that is the overly aggressive map and not the other mods.

My 320d has been running promotec software for 35 000kms with dp and after the car has warmed up it sees red line everyday.

The GM boxes are going to break whether the car is stock or not. If its modded it will just happen sooner. That is a flaw with the gearbox. Gearbox rated for 360nm and the car makes 390nm or 410 nm depending on what you have. And now modded makes 500nms... I'm sure you can see where the problem lies.

And people also do the same with modded 335is 135is m3s and m5s and their cars are fine...
