dyno lies....

[dlextreme1977]

anybody who tells you they can 'predict/guess/conjure up' crank power is not being truthful or is misinformed/uninformed...

the only number that matters is wheel...
that's what we use in the States, because even dyno mfgs will tell you anything else is bogus...

only 1 dyno I know of actually measures losses, a MAHA
and the RS4 runs I've seen run 310-320 wheel with 100-110 in losses
that's 410+ HP

anybody who tells you an RS4 makes 370 at the crank is either misleading you for unknown reasons, or does not know of what they speak, ie, misinformed...or both...

the fact that a car with a >50% lb/HP deficiet, is as fast as the other car, defies all logic that it makes 370 crank, or 270 wheel minus losses

that would make the actual delivered wheel lb/HP ratio's:
M3 3550/378 ~ 9.4 lb/HP
RS4 3980/270 ~ 14.7
a 56% difference, the M3 should be 25% faster
yet, Ring, 7:58 vs 8:05
1/4 mile even, sometimes RS4, sometimes M3...
definitely not 25%, ie, RS4 13, M3 9.75, lol

actual dyno, RS4, exhaust & K&N, no HP gain, no tune, 20k miles, never cleaned
wheel 320
losses 104 (actually measured, not guessed or derived via divine intervention)
crank 424 (rated is 414)

this is what a dyno sheet should look like, all data is present, all amb conditions noted, no mystery
note, only run to 7300, there were a few more ponies available

Has this guy lost the plot? I won't speak for the rest of the chaps on here but in the last thread you stated (and i quote) 'all the mag tests have the M3 a bit faster...times are close, trap sppeds a bit higher' and then posted 3 pages of dribble contradicting himself saying an rs4 is faster including bogus ring times.

Now you are telling everybody on this forum that all the dyno fun days and runs they have conducted are a joke despite not one car in the uk having made stock horsepower and they must be talking nonsense? This cat has his head in the clouds. I'm out of here before he starts fumbling through more magazines with his magnifying glass and dishing out some tasty new formulas

Good combo- surf and turf- YUM!

followed up in a few minutes with shortcake, whipped cream, and fresh picked strawberries

[ArthurPE]

well, well, well, look who's showed up, lol

I also stated, depends on the tests...some have the RS4 faster
as it is around the Ring, but in reality, they are evenly matched
despite a 56% wt/Hp disadvantage...

no need to get your panties in a bunch sally...no need to insult
dribble...I think you mean drivel, you should learn that one
childish, silly, or meaningless talk or thinking; nonsense; twaddle.

the Ring times are accurate 7:58 vs 8:05, RS4 favor
even if you chose the slower, 8:09 a 4 sec difference (0.8%), over 13.2 miles, with a 56% wt/HP deficit? really?
that means the RS4 only has 64% (1/1.56 ~ 0.64 or 64%) of the power/pound as the M3!?
and yet is as fast?

I posted a dyno of a car making 420 HP

again, how can a car with a 56% wt/HP deficit, be as fast, or equal, or only a bit slower, depending on test?

btw: better to have had the 'plot', and 'lost' it, than never have had it...
I know what to look for, you are still stumbling blindly

hmm strange guy..

perhaps you could explain how with another formula? brace yourselves....


anyway i'll let you bore the rest of the guys on here- who seem a good bunch, enjoy guys...

[ArthurPE]

so no facts, only insults...
everyone who sees your BS is not 'strange', only observant...

8:05 M3, same driver
8:09 RS4, same driver
8:09 M6, same driver, same wt, 500 HP, sport tires
8:13 e60 M5, 100lbs heavier, ~200 more wheel HP (465 -270), yet slower, same driver
8:15 Corvette 400HP, 800 lbs lighter, much more torque, same driver
8:20 RS6, ~same weight, same driver
8:28 e39 M5, ~same wt, 400 HP, same driver
8:25 S5, 30 less HP (370 vs 340), a bit lighter, call it the same, same driver, 16 sec difference, driveline losses should be ~ the same
the RS4 weighs 400 lbs more than the M3 and has 270 vs 370 (100 less delivered HP) but is only 4 sec slower
how can this be?

[S2tuner]

Arthur? An RS6 same weight as an RS4? you must be joking, have you ever been anywhere near one? An RS6 has 450 PS and weighs roughly 2100kg with an average weight driver in it and a full tank of gas, if we're talking about the Avant. Saloon weighs marginally less but still not close to a B7 RS4.

[ArthurPE]

Arthur? An RS6 same weight as an RS4? you must be joking, have you ever been anywhere near one?

weighed RS6's ~ 4050 lbs
RS4 ~ 3980
1.5% difference...approximately = '~'
and it's 11 sec slower, same driver...
but has 80 more HP (450 -370)

not sure what your point is

[S2tuner]

A question comes to my mind Arthur: all the time you spend on this and other forums preaching your theory of the conspiracy and bogus dyno plots, don't you have a family to take care of? Heck, even if I was paid to spend as much time as you on forums, I'm not sure I would TBH.

A customer of mine has had his RS6 avant weighed at 2100kgs with him in the car and a full tank of gas. His weight is around 90kg. Just facts as you always say.

when the facts aren't on your side, attack the messanger...

I would be more concerned about your family...
mine is very well provided for
Audi paid me $300k last year

I know you have vested interest (ie, tuning company) in marginalizing my posts, but don't sweat it, I work at least 20 hours/week at ~$300/hour,
taxes suk, but at least I have time to call BS on guys like you...

and when it comes to dyno data, 'plot' is the correct term for you

btw: isn't it after 1:00 AM in the UK, don't you have to work to support your family? rather than worry about mine?

TBH = to be honest? why do you feel the need to say you're honest?
wouldn't we assume you are? or are you trying to tell us something...
you're honest now, but not always?

if these are the questions you ponder (what is Arthur doing?) it's not I who have too much time to waste, trust me, you'll not cross my mind again until the next inane, passive agressive post

I have no vested interest in whatever but hey you're the victim. Call whatever you want on me and stop waving your d|ck with your wage, because I don't care how much you earn at all. What do you have to say to MY figures that have been measured on a calibrated scales at a french techical inspection station (equivalent of MOT)? An RS6 under 2 tons? please allow me to laugh at you being so naïve.

It's 2:18 a.m. in France and I do whatever pleases me. TBH is just a saying, so now instead of answering facts numbers and data you're picking on semantics? I'm much younger than you but I won't be a hypocrite: get a life.

[ArthurPE]

you were concerned (sure you were) about my family...I assured you they are well taken care of...

perhaps you should also do what pleases others, perhaps your employer and your family, anything else is selfish...and self-defeating/counter-productive...since we're offering unsolicited 'advice'

actual scaled weight(s) : 4050 to 4080, depending on source

and btw, you're correct, you won't be a hypocrite, you ARE a hypocrite...
you know what that means correct? because you just did it

get a life...guess you told me

[S2tuner]

Blah blah blah, you're boring. My employer? I guess he's happy, as my employer is yours truly. Family? I don't have one, because I spend too much time calling BS to all your posts that make you sound like Audi is paying you to come here and bore us to death with your facts, figures and formulas.

I do think you're someone very intelligent and bright though, but can be soooo boring just rambling on and on and on the same darn thing. Ok you win dear Arthur, the B7 RS4 DOES HAVE 420 PS and everyone stating otherwise is a crook only with a vested interest. Does that make your life better if I say it?

[ArthurPE]

no one has yet offered a reason or explanation:
RS4 3980/270 ~ 14.7
M3 3550/378 ~ 9.4
the M3 has a 56% (115.1/9.4) advnatage, yet the cars are of similar speed...
how can this be?
