coming soon!!

And all the doubters have gone into hiding LOL!

Not hiding, just watching.

The moderators on audizine believe this is the same person that has posted at least 3 similar "look at this great build" threads, all of which got to the final build stage but then never offered any proof of the claimed performance.

This guy claims the moderators have confused him with someone else, so let's all just wait and see if this thread delivers i.e. dyno and/or measured acceleration times plus videos of the TT RS4 running as fast as claimed.

BTW 12psi is a not insignificant boost pressure for an unmodified engine with a 12.5:1 compression ratio.[/quote

Mrc runs 14 psi on the r8 v8 single turbo

This could be epic! well done for having the balls to take this on!

I'd say the majority of them/us (as I'm def still in that camp) are just not bothering to sit and watch for updates on this build. If it works out, great news and well done. If not, then I'm sure a lot of people won't be surprised. And as for the 'well he must be telling the truth, there's photos' lot... I could go out and stick 4 turbos into my engine bay, doesn't mean they'll do anything. And one bit of piping does not a twin-turbo setup make (poetically, not bad grammer).

Exactly Dave.

Mocking something up to fit is totally different to an engineered solution that works time after time in the real world.

[TonyHayers]

I'm a bit of a doubter, but at the same time I hope it's a successful project and that the OP shares more specific details of the build.

Do you really think someone is going to take parts out of the engine bay and buy the turbos just to make up some sort of story??? Really?? Is this some sort of negative English attitude to want someone to fail, so they can say I told you so

It's not as generalised as just wanting someone to fail, nor am I English, but rather the fact that this guy has a EXTENSIVE history of lying and misrepresenting his tuning efforts on pretty much every VAG forum going. I'm not saying he took out parts just for the story, but rather than showing a picture of the turbo (one of them anyway) in situ doesn't constitute a successful install. If he/they manage to get a twin-turbo setup working on an RS4 it'll be a huge deal for the community, but I think instead we will not be shown the almost inevitable pictures of a melted engine bay, or the 450bhp dyno graphs and instead the thread will taper off into an endless list of members asking "so? what happened with this?" with no word from Mr Molliere.

Ok,i didn't know he has history

I'm still here, bursting with doubt.
I think it'd be massively compromised.

[PetrolDave]

I think it'd be massively compromised.

My main concerns are:

- the fabricated pipes appear to be only spot welded, i.e. not pressure tight. Optimistically this is just for a fitment test and they'll be taken out once the fit is proven and seam welded...

- does his tuner do mainly drag conversions (at least the pictures that have been shared are of a "2000bhp" Evo)? If so are they fully aware of the cooling needs for a road car that needs to run for hours on end not just for a 1/4 mile WOT run?

- questions about tuning seem to have been brushed aside. While a drag car just needs to produce power at WOT, a road car needs to have drivability at all throttle openings and resulting from changes of throttle openings (e.g. tip in- tip out) - the engine management experts I used to work with always said that drivability took ten times as long to get right as getting power.

I would LOVE this to work, but I have to be sceptical because of OPs history on AZ is poor/bad (something he denies) and there seems to be insufficient understanding of why it takes the major car companies so long to develop a reliable turbo install/tune.

[docurley]

Spot welds are used as a temporary fix till everything aligns ok before the final permanent weld.

It is strange why none of the major tuning companies have managed to fit a turbo kit in these cars but have all gone the supercharger route.

[Bladerider]

Personally,

I dont know this dudes history
I tend to be fairly sceptical
But I also try to keep an open mind
Im used to much more serious tuning than alot on here who think an exhaust is a big deal

Hence I feel pretty neutral regarding this whole scenario

BUT I do think that shooting a guy down for trying is a bit lame, I think picking stupid faults like spot welds just highlights peoples total lack of knowledge when it comes to actually fabricating stuff on cars rather than having a tuner bolt on a shiney bauble and hence makes you wonder why they even bother commenting on stuff they have no frame of reference to discuss, and mainly I think that getting a massive hate on about mapping driveablility and cooling on a first of a kind, known to be difficult, totally custom install is a bit like moaning that the rooms are painted the wrong colour and the internet dont work in a house made of unicorn horns !!!

Some basic things need to happen first, so that the more subtle things can be addressed. ie it needs to run in order to melt stuff !!! lol

I have no doubt it will have issues and may even go pop, but the very fact someone is prepared to have a go should at least deserve some respect and a little bit of courtesy in letting them do stuff before then ripping it to shreds.

As for the OP then the only advice i would give is just stick to discussing what you are doing and probably dont bother with the "its gonna be X,Y or Z" performance etc as that just opens you up to even more conjecture on what might be rather than just discussing your progress as it happens.

Good luck.

the az stuff it all stupid rumors that have been created by some stupid jealous kids

cost i presume and lots of fab work and machining parts

I think someone already mentioned it will probably not be a viable manufactured kit due to the amount of work and fabrication hence time and cost therefore supercharging is the preferred option. That doesn't mean it's not impossible, it just means to me that it could work as a one off but the final purchase cost for the customer will be too much for any of the big tuners to develop & bring into production.

Hi ChargedRS
I can understand why people are getting so emotive about this project. I think what you are doing is very brave given the challenge of space, cooling and mapping.

I say keep your chin and push on.
