Bobby Singh A4 3.0 TDI build thread

[The Black Panther]

It doesn't matter what he told you.
I could say ive got ant gravitational shoes and survive on sunlight instead of food but doesn't mean to say its real.

The whole reason for evolution of the BITDI and TRIDI units used by Audi in the BITDI and SQ7 and the Quad Turbo units used BMW in the M550D was to overcome the inherent unavoidable lag created by trying to use single larger turbines to increase power output.

Now if you think Bobby Singh has singled handledy out engineered what BMW and AUDI with their Billion Euro R&R budgets couldn't achieve then you need to have a serious word with yourself and a wee lie down.
Bobby Singh no matter how much you admire his pioneering spirit ( which has to be admired ) has not cracked the engineering limitations that BMW and AUDI could not and no doubt forced them to base their introduction of sequential turbo units to their diesel power plants

The Lag will be massive compared to modern standards. Its just a fact of psychics.

If I remember what he told me correctly, the lag shouldn't be that bad. All depends on the hardware and execution, and we all know Bobby's skills and knowledge.

I'm sure if he wanted a bi-turbo he would of retrofitted the unit and associated pipework and electronics.

Wow, really dude. You've got some issues in reading comprehension. Nowhere did I say there would be less lagg then a bi-tdi setup. Only that the lag wouldn't be that bad, there's always going to be a trade off. You can interpret that all you want. I just feel sad for you that you went to the trouble of writing all that! A "wee lie down" would be in order for sure!

 

[bobby singh]

Don’t waste you time Timber.

Mr Audi Where did i say single turbo has less lag than bi turbo?

 

[The Black Panther]

Hey no need to feel sorry for me im fully self sufficient.
There will be a bit more than a wee trade off between the power plants. But if your unhappy about being given practical evidence of that and you choose to take offence where none was actually given then apologies as none was ment.

Id advise even if its someone states something check it out for validity. But its your choice amigo. Good day.

 

[The Black Panther]

Bobby i haven't seen you say it would have less lag than a bi , tri or quad turbo. Its physical impossibility for it to do so so its not something i personally would acknowledge in any capacity other than addressing your quote below.
But according to Timber Vd he quoted you was saying " its wouldn't be that bad ". Mmm ! Thats kinds really not true is it. Compared to the modern diesel power plants supplied by the Germans its going to be kinda pants isnt it ?

Playing about trying to tune diesels with single turbos to do record 1/4 mile times or achieve ultra 0-60 figures in this day and age of sequential turbos is about is about as sensible a use of time, effort and money as trying to tune a Peugeot 406 1.9 tdi to perform like McLaren F1. Its just ludicrous especially as BITDI are easily affordable and reaching £20 k theses days.

Im only providing practical evidence Bobby on why Audi and BMW evolved away from the single turbo model for their sports diesels as the power output, 0-60 and fuel economy was all limited and so by natural evolution they moved towers sequential turbo systems.

I can't see why anyone would get their knickers in a twist over it. The psychics of this are sound and unarguable.

Don’t waste you time Timber.

Mr Audi Where did i say single turbo has less lag than bi turbo?

[TimberVD]

You said the lag would be gigantic. I simply disagreed and said it shouldn't be that bad. Maybe gigantic by your own standards, not by many others. It will be driveable for a daily. In the end, it's an endeavour to find out the limits of a single turbo. Which Bobby is doing, and just fine, might I add.

Nothing more, nothing less.

 

[The Black Panther]

I agree Timber its a good endeavour but it wont meet the performance figures of the new sequential power plants.

These new era of cars are expensive though and mine was just shy of £60 k new when i got it direct from the factory to my spec. I STG 2 (I had a lot people saying id blow the gearbox up) it immediately and STG3 (I had a lot people saying id blow the gearbox up) along with RS 6 calliper and discs around after the third year just before the warranty died. I love it. My car gets heavy use and iv removed the Rev limit Delete. Top speed Delete. Launch control rev limit delete to get extra out of it. I do launch control with the rev limits removed a lot to heavy DNB at the traffic lights especially on roundabouts . It puts a lot of extra strain on top of the 912 nm torque the gearbox is channeling but its too ****** addictive not to. Plus i have that stupid kufatec box that makes the BITDI sound like Aventador and that noise itself is stupid and addictive.

RS6 Brake upgrade is a big big improvement on the original BITDI calliper and discs.

[tech838]

Bobby I for one can't wait to see where you take this, an updates been a long time in the making I'm sure!
As the owner of a single turbo 3.0 tdi its great to see someone take this set up to the limit and I'm always in awe of your work

Especially as you put the effort in to share your progress with us on here!

 

[The Black Panther]

Audi RS6: 5,0, v10, 700HP and 950 nm, 0-100kmh in 3,5s Batters the Passat

Ferrari's 458 official 0–100 km/h (62 mph) acceleration is 2.9–3.0 seconds.

So your trying to suggest that the Passat is running sub 2.9 secs on 3-400 BHP ?

It may well show it beating the Ferrai in that video but if the RS6 is whopping its *** at 0-100 kmh time of 3.5secs and the Ferrari is running sub 3 then there is a WEE bit of a miss match there. Maybe some ones Gran or James May was driving the 458 !!


So based on your Passat Ferrai battle you tube video where the Passat destroys the Sub 3.0 sec supercar it suggest that its running close to the fastest car ever built in history thats running sub 2.0 secs.



Here is the Passat being tanked by a Fiat Uno ! LOL !!



Facts not just appearances. Study the data GaZwould - Apply logic. Not everyone is a sleep walking Zombie know what a mean dude ?

So you like it now that you have realised it has two turbos

 

[holmefield]

Can i just say that whilst i'd love a BiTdi, ( i have an A7 245bhp ) £20000 to most is still eye wateringly expensive Mr Audi for an A6/A7 that would be way up on miles and very low spec believe me i looked and looked b4 giving up on getting one..

Add to that the fact that if you did by a BiTdi @ around £20000 it would be @ around 100000 miles b4 you start mapping it and starting to need work..

So to me i admire Bobby sing for pushing the limits of "older" but still great single turbo diesels....we dont all have lots of money to spend tuning our expensive cars, so good going i say extracting what power you can from the single turbo'd Tdi lumps...

Seems like because someone has bitdi, it makes him think he is above rest of single tdi owners. What a ****.

Looking forward to see what you brings next Bobby Singh.

 

[The Black Panther]

Nice. Name calling way to go how original and entertaining. We are talking about cars and power output ?? ? Stop taking it personally mate ? Have a cup of tea, chill and relax. Peace

This is a build thread for Bobby's car, not a place for you to chat ***** and go off on a rampage.
If you want to discuss the pros/cons of single turbo v bitdi etc and tuning on a Bitdi then perhaps start your own thread elsewhere.

 

[The Black Panther]

Last time i checked free speech was allowed and you aren't a moderator on these forums. In fact the only thing that isnt alowed on the forums is personal insults. Take note. Re read the forum policy and abide by the rules.
I suggest you pipe down, look at the data posted above and from that conduct yourself in a rational orderly manner and stop insulting people and detracting from the relevant discussions on tuning diesel engines. Moving on ..........

Im not taking sides and frankly i couldnt care as we are all entitled to our own opinions, but Mr Audi you do seem to court or crave attention, it's for you to decide which.

Yes you own "out right" ( well done ) a highly modded BiTdi most of us with 3 litre Tdi's own the singled turbo'd models.

Therefore its in our interest to discuss and watch what somebody is trying to achive with there single turbo'd Tdi lump..

If you dont agree fair enough but please try to accept others opinions they mite not be right and you mayb right, but you are starting to come across as a key board bully who has to be always right.

 

[The Black Panther]

Im not on the forum much so i'm not interested in getting aggrandisement from on an online forum with a group of strangers. My self esteem and personal prowess are intact.
I agree any advance on tuning any of the diesels is great and should be shared and evolved and is exactly what i have done with all my mods including the RS6 brake setup which was not straight forward in and of itself for number of reasons. Do a search.

But to be completely frank and for context on these posts above Bobby Singh's over the last year since (and once again the other day again )starting since i went ahead with the stage 3 tune has often joined in on the BITDI tuning threads and claimed the figures i and others have posted as false and totally impossible ? ? Do a search you'll find the posts.

Now if he had a BITDI that would be a start for one thing. But he proclaims to be ahead of all the big tuners in terms of knowledge application and process of tuning the BITDI diesel and that the tuners are all posting up false figures and that the figures i posted up are false as well. He even claimed that its impossible to tune the BITDI to 450 bhp+ without changing the fuel pump and that the rolling road used by others must be false. It is irritating in a humorous way and i should mention obviously questionable on his part in terms of psychological outlook in logical application and critical thinking.

My background is tuning, starting and problem shooting 800MW Nuclear Turbo Generator sets and 450 MW CCGT Gas Turbines and i travel throughout the world from Brazil to Russia doing so working for myself with repeat business month after month customer after customer and i ma real hands on engineer not some graduate engineer that has never had his hands dirty. If i had logic ofr mental health problems and was into stroking myself believe you me id be quickly found out and removed from the organisations i consult to. The fact that ive been doing this for 15 -20 years tells its own story.

With the background i have being in Nuclear engineering we were trained to spot and stop faulty thinking within individuals and group behavioural psychology in its tracks as the consequences are potentially incredibly serious. You can understand why. We are trained to spot who would jump to conclusions without evidence, process and backup or proclaim to be self stared aggrandising experts etc. When we stop people on these jobs and remove them from the teams or decision making process because of their own behaviours then it often isnt understandably received well. They even accuse the the leaders of bullying sometimes. But tbh it is what is and we have to back up our decision making process with logic, evidence and justification.

Im not taking sides and frankly i couldnt care as we are all entitled to our own opinions, but Mr Audi you do seem to court or crave attention, it's for you to decide which.

Yes you own "out right" ( well done ) a highly modded BiTdi most of us with 3 litre Tdi's own the singled turbo'd models.

[xJay1337]

But what relevance does that have on your cars performance. Sounds like you are blowing trumpet

All Bobby has said is that some companies fudge egt sensors to prevent protection kicking in. And that a tuners own dyno is more likely to be over estimsted.

Asking "have you ran on an independant dyno" is hardly stalking you around other threads or saying that everyone else is rubbish.

I don't think Bobby would talk to you about these nuclear generators you claim to work with, maybe don't try and tell him things that he perhaps knows more about. He has been in the tuning game for as long as you have been doing your work.

I know first hand the BS coming from europe in the diesel tuning world. Dyno numbers sell tunes. Simple.
Eg in the 2.0 cr world European claim 290hp from 2260 kit stock head stock fuel pump.
Claims I have proven to be wrong myself.

Btw rs6 brakes are a simple swap for an engineer of your calibur

 

[The Black Panther]

Hey I've never tried to tell Bobby anything he is the one proclaiming everyone else is wrong and he is the only one that is right. I suggest you read the posts and put the homework if your that keen on commenting and defending him . I doubt that you will.

I was happily going about my business before he chose to come in and starting pro claiming to be the the messiah of Diesel tuning and the BITDI Stg3 tuners where living in an imaginary bubble. I never went looking to post on what he was doing it was the opposite way around.

As for ******** numbers and your generalising on European tuners please detail your timeframe and references for such a substantive statement. Any one can like Bobby or yourself and point fingers and say i know better and these guys are crooks. Lets see you prove it with anything to backup up your statement.

Here is the tuner i used and Bobby says are telling lies about numbers and have crooked dyno's etc etc They process 20 odd cars week Porsche, Audi VAG group and others. https://www.facebook.com/JDEngineer...xOqPdH3gjZ7Zg_YfuJH669QngzqLdMeCTI73ROikHVD1s

As far as i can see Bobby who you say has been tuning for 20 years ( how do you know ? ) is an advance amateur tuner ( his work looks good) and has never made the transition into providing a professional product as a regular business to the general public.

Jd engineering started as an amateur outfit and then organically grew from word of mouth. And they have an excellent reputation.

Lastly look up the RS 6 brake upgrade and as i said initially it was posted to allow others to tap easily into how it was done and while it maybe relatively straight forward apart from finding a custom manufacturer for the brackets its very very useful for other to see the parts and process involved. There are many who don't know the ins and outs of it all.

But what relevance does that have on your cars performance. Sounds like you are blowing trumpet

[xJay1337]

I have read the posts.
He says nothing out of line and has not proclaimed to be the messiah of anything.

My own experiences have proven most of Europe to be full of BS when it comes to figures and performance in general. Not all. But many.

Oh well, I have learnt from your posts that you are someone not worth entering to a discussion as they don't understand their own car. You took your car to JD, got given a dyno printout and take it as gospel. Do you even know basic parameters of your tune eg ig, railp, boost level , egt?

 

[The Black Panther]

Please detail experiences ? Otherwise it just looks like a mouth talking with not substance to back it up > ?

[The Black Panther]

I spent a year researching STG 3 before i committed especially focusing on gearbox torque limits and failure. I equally researched and then implemented successfully the RS brake upgrade including sourcing custom calliper mounts which i had the first produced on the market as they weren't previously available. Hardly someone who doesn't know anything about their car. But
you can ignore all that

My uncle told me this and its seems quite pertinent.
When you're dead, you don't know that you're dead. It's difficult only for the others. It's the same when you are stupid.

Compliments to Bobby for the result! I am curious how it improves the previous 12.1s /402m.
As regarding the JD engineering, it's all about big numbers. That is optimist by 10% , a real joke.

After being a victim of the high numbers and dyno queens i dont believe in numbers anymore.

 

[The Black Panther]

If you don't believe in numbers how on earth can you benchmark, show and measure output ?? Or is it only special dynos that accurately measure ?

Its not my intention to spam on Bobby's thread, please open a thread and we can discuss there. Bitdi vs single turbo or whatever you want.
A 459hp car bitdi must do 11.8s on 402m or less . Measure acceleration with gps from 100-200 or do a 402m run.

Mac above used to believe these high dyno claims several years ago.
Over the last 18 months due to His own experiences and learning, and also evidence from my car and Bobbys car, he also at least understands the dyno lottery.

I will happily argue all day with you. But not on Bobbys thread - it's not fair on him and I will delete my posts to tidy this up when I'm next on the laptop.

Please start another thread and tag me in that if you want to continue this discussion.

Anyway still not one example of so called many fake European DYNO and BHP figures offered by yourself. I thought they'd be dripping of your tongue they way you proclaimed it so righteously !!!

Cease and desist and cower back in yon cave where ye once came fae xjay !!
