RS4 B7 Stated Power claim of 420ps MKII

[Sims]

you call it carbon denial, I call it objective reasoning...

How many on here are convinced. I suggest you start a thread and ask people to sign up. A simple question that has been your platform - " I believe carbon does not affect more than 2% on power or economy, and that there will be no long term effect". Don't twist the question Surely that's fair.

and since you've been here, yes, many have been in rebuttal of BS you post, as in 'the RS5 is derived from the V10, so it's different',

. That's what Audi has told journalists... Have you a statement from Audi to say the RS5 engine is the same as the RS4 engine + different ECU & air. That's not top secret that you cannot divulge here.

why don't we leave it up to the readers to decide the merits or range of our posts...most have been around longer than you, so they have a pretty good feel for my 'pre sims' posting content, lol

Everyone can see all your posts, and mine, and also yours on other Audi forums e.g. audizine etc. And all these pre-date my arrival. From the get-go you have been on the carbon case., and how you came to attack me and making baseless accusations. Check out the 1st 420ps thread.

You have good engineering skills - how about telling us how to prevent carbon build-up altogether. That's a challenge for you.

I have had my car for three years now and although im not a big poster have found this forum a great source of information, however recently it has become nothing more than a place where 'some' people have nothing better to do that slag off the rs4 and fellow owners.
.

You really ought to read the original 420ps thread.

You have noticed nearly all the disagreements are on Carbon, and have been well before I arrived on the scene. This subject ought to be on a different forum. I do agree it can feel negative, especially in this phase where we have conflicting data.

This debate is on other forums too....

I have read the original thread, took me a couple of days but still...
I have had my car just over three years and covered over 50k, yes it has had the odd issue but for a car in its class I would say it was a relative bargain and certainly the best all round car I have yet owned.
My point is other forums tend to be generally positive about said car
however on here its non stop whinging, (I get enough of that from the mrs).
I have no doubt over time the carbon build up will slightly affect performance but what cars dont lose something as they get on in life?

Anyway as I mentioned before if I have nothing worthwhile to say ill shut up so bye for now and dont let the carbon build up worry you too much, life's too short

as I said, 50% of the people believe a bowling ball will fall faster than a cue ball...so I'm guessing those who can understand what I post will 'see' more than those who don't...

I notice you have not answered 1 single question: nor will you
1) how does it <beep> timing? what mechanism? detonation, pre-ig, mis-fire?

2) how can the fuel NOT be mixed
1500 psi, atomized, velocity >1000 ft/sec >>>> air stream, thorough mixing...
> higher than it's vapor pressure, soon as injected, vaporizes immediately...like releasing water >212F under pressure >>> gas/vapor
piston speed > air speed (90 vs 70 ft/sec or so), actual a vacuum pump
shot into the stream as it passes the nozzle, mixes with entire charge...
compressed o 12.5:1 reducing any gradient differences by the same factor

3) two cars recently cleaned, both modded
8.4 or socorrected, the same as all uncleaned, unmodded cars

who cares what others 'believe'? you seem to be the one with the issue on that matter...lol I do know, the technically sophisticated seem to believe 2%...I will trust the science and the facts...

Audi said 420 HP, you don't believe that? lol but you believe other things they say...er, riiiiight

the FACT is, the RS4 is the mother of the V10, and the RS5...
look at the link I posted, the numbers don't lie...fact is fact whether you believe it or not...

you are the one who ruins threads and attacks and demeans others...as you can see from the other posts I'm not the only one who sees it...you have never answered a single technical question...you only attack others who offer such information, you contribute less than 0...
in fact the only person who doesn't see it is you...
you know what they say, the egregious is the last to know...

it can't be prevented...the good news it is not an 'issue', costs negligible power, if any...

I don't need 'assignments' from you, who do you think you are? it's laughable really

btw: recently you've really been agressive and on the defensive, much more than usual...you seem to be unraveling, don't take it so seriously...again, I'm not the only one who has noticed your behaviour has become hostile and erratic...

now I know the retort: " it's Arthur's fault" or " look at his other posts" or some such distration/redirection, but honestly man, that won't help you, there seem to be bigger issues out of my control that I have nothing to do with...others have pointed it out, take heed and worry about yourself rather than me

this is a feedback comment from a moderator, formerly on audizine, started his own site...we debated the issue, strongly, but did not resort to the tactic of assailing each other...he's a car guy, and engineer, and imo, a smart guy...

"very well said A! You're a great contributor here on EA. Voice of absolute reason. Two thumbs up. Sorry for any bickering I did on AZ...at the end of the day, I think you were WAY more right. That's hard for me to admit..I'm pigheaded as hell!"

bear in mind, he's the site owner and a moderator...

now, having said that, have I had heated discussions with people? of course, there are people like you everywhere spoiling for a fight...
ignoring the facts, never answering a single question posed...
but unlike you, I try to let the science 'do the talking' and not let it get personal, and I haven't in this case, despite your hostility and anger I harbor no ill will...sims, it really doesn't matter...

I've actually had people ask for my number to discuss issues...
I'll be talking to a forum member soon, seems like a great techncian and a pragmatic realist...

a few more:
I like this guy, he's well respected technically, he's a real down to earth sort

just wanted to say thanks for all the help on the other site. Justin showed me some things you wrote before they got deleted he then told me you were this guy over here. Once again thanks bro.. your aces.

I always admire your posts and input.

another Az senior member, a 'tech guru':

Im with you bro. I wanted to step in like 1000x for the carbon thread I was 100% with you. In some cases it's just an excuse.. No one was actually reading what you wrote.. Any way good looking out..

Thanks there are people like you..
Thanks for the lesson and the education of pushing the guy off his high horse.. You are the example of what I was talking about.. I just didn't know how to do it...

It's clear when people that know have the info its helpful info... YOU dominated that point..

Thanks for this and much more

trust me sims, the 'angry' pm's are literally non-existent...

I'd like to post some of the ones I've gotten here, but they were transmitted in confidence...

so am I perfect, not by a long shot, am I the demon you try to paint me?
it would seem some think not...I know, they're wrong, or like minded, or have some malfunction...

OK

Are the Audi R8 V10 and Gallardo LP560-4/LP550-2/LP570-4 SL engines identical (except for ECU and exhaust). Forget about the old Gallardo engine.

Is the 5.2 FSI V10 used in R8 V10 and Gallardo LP560-4 the new V8/V10 design.

So although same displacement internals of the engine, is it not different to the RS4 engine?

RS5 engine, it seems, is based on R8 V10 engine internals. It is wet sump(not dry sump like R8 V10) engine with modified internals.

[ArthurPE]

the Lambo engines are derived from the S6/S8 line of V10's
which are all derived from the RS4 V8

5.2 V10 40v FSI (LP 560-4/R8 )
It is a development of Audi's fundamentally identical 5.2 V10 FSI engine as used in the Audi C6 S6 and Audi D3 S8
This variant has been de-tuned for the Audi R8 V10.

5.2 V10 40v FSI (C6 S6/D3 S8 )
based on Audi's V8 FSI engines, and retains the same fundamental design principals of the V8 FSI, including the crankcase, cylinder heads, valvetrain, fuel system and intake manifold

the RS4 engine spawned BOTH of them, the RS5 is identical to the RS4
at best the engines are minor evolutions, but actually are derivations, NOT 'entirely new engines'

the RS4 and the RS5 use the same oiling system with variable output pump
yes you could say the RS5 is based on the V10, but the V10 was based on the RS4...so ergo, the RS5 is based on the RS4, in fact, identical
and the chicken came first, or was it the egg?
but we know the RS4 came first
