Saki that is really unbecoming of you !!!
What?? Back to your dirty trash talking ways again? Why don’t you get off Eurogears dick and don’t tell me who’s tit to suck or not to suck on, that is not for you to decide thank you very much. All you do is talk shit about shit you don’t own and don’t know shit about and belittle people that come and try to post on your forum, way to go.
Will JHM catback mate up to stock downpipes?
If they do, I will post log results with and without JHM downpipes once I get my catback and downpipes in. Would that satisfy your curiosity Papery?
This thread is fucking awful, people.
open and shut we all know hte JHM 2.75 exhaust works. Its been seen on the dyno and seen at the track. The bigger issues here are the paper is ass hurt because his favorate companys products don’t seem to shine like he wants them to. So papaer eat this shit burger.
WITH CATS THATS A 20whp 23WTQ difference… and you don’t have to pull your motor… 2.75 jhm exhaust stock and with the exhaust with cats… There are more a few other guys did testing as well I can’t find all of them.

Then on a smaller exhaust
AWE

They are also offering $50 off if you buy the tune at the same time.
Looks like the group buy is live now
So they have about 15 buyers for the catback or the downpipes or both? That’s a nice chunk of revenue for the shop.
After hearing some the built motor stuff they’re working on for the B6/7 S4 right now HOLY FUCK do I want them to do well and get these things out to the market.
yeah the 10 individual orders was met so the group buy went live.
The JHMPWR is looking pretty beastly these days 
Are you going to go with the JHM RS4 SC when it’s available?
Chris, I’m not understanding your post. The AWE charts are pretty clear but yours isn’t labeled. Are you saying that you dyno’d 330whp/273wtq stock and then 345whp/294wtq by adding just the full JHM? No cc or anything else that could have skewed data? You state that with cats thats a 20whp and 23wtq difference so I’m just trying to figure out what all your numbers are coming from.

^^^I think he was saying vs. stock, not vs. AWE
you wlaked in midway through, but paperishplastic was pretending to calling out the JHM exhaust, but really he was just mad it me and a few others for pointing out that his $2500 Eurocode headers appear to do very little on stage 1 or 2 B8 S4s with the much cheaper 034 HFC or test pipes…or even stock exhaust.
In reality he knows nothing about the Rs4 program at JHM or anywhere, so I am not sure why anyone really bothered replying to his trollish attempts to poke the forum.
Chris’ post seems to show an RS4 picking up good gains with 2.75" exhaust and a little less with 2.5" exhaust. he was showing that going from stock (2.36") to bigger (2.5") to bigger still (2.75" shows incremental gains as you go, provided the system is well designed.
Nobody really gets just downpipes then does a dyno. Generally guys get a tune and catback and downpipes and dyno that setup.
If stock cars are dynoing around 320 whp at the 034 dyno when carbon cleaned, you can deduce that a JHM fullback + JHM tune should be good for about 40-50 whp and the same wtq (based on the 2-3 cars that dyno’d there afterwards) depending on whether you go catless or not (probably closer to 40 for catless cars). That’s a land and sea dyno for what its worth. I think using a stock clean car as a baseline, 320 is pretty common no matter what the dyno type.
Of course this is all only relevant if you care about the dyno (which I don’t).
I think a very reasonable thing for people to try to determine is the
delta for specific mods. No one will really argue against what setup has
created the absolute peak performance that has 12.2 results, but that’s not
of utmost importance to everyone. I know for me Id like to know what to
expect to determine if its worth the $3k+. On my local dyno a stock RS4 is
322whp/265wtq. With stock tune, piggies, intake spacer, lw crank, and Milltek Im already at
348whp/285wtq. Then the analysis becomes, is $3k really just going to get me
10-15whp. And if so for me it’s probably not worth it. So sure, 1/4 mile times
are great to determine what’s the absolute fastest. But if having the fastest
1/4 isn’t of utmost important to someone, as with 90% of RS4 owners, some other
means to evaluate delta would be relevant. There are people who would
just buy dp’s or may just want a tune. Sure, they all work well together and the
sum of all gains is greater than the individual gains. But that doesn’t make
the specific analysis any less relevant. Hopefully at some point when people start
taking delivery someone decides to give back to the community to get results for the
different components for the benefit of the community.
Sense:this makes none
You want a test to NOT determine how fast your car is?
You want a dyno sheet instead because you’re not interested in accelerating fastest? So you’d rather a test that can fool you? Dyno is perfect.
Well I suggest you buy a milltek fullback and an epl tune because they have been proven to not be ‘utmost fast’.
Oh look… You already did!
If you don’t care about 1/4 mile times, does that mean you aren’t trying to make your car faster? If not, why spend any money on changing the car at all? Just to make it look and sound a certain way?
Most people look to the dyno results as an indication of performance, but the argument made is that the dyno is not a very reliable predictor of actual real performance. Cars that dyno well dont always run well. The 1/4 mile is more tangible and can can be reproduced reliably. If your car dynos 500hp but still has the same 0-60 acceleration time won’t you feel that you wasted your money no matter what the dyno says? I would.
I have never taken my audi to a track. Maybe some day I will, maybe not. But I appreciate that it is a standardized and reliable way of measuring performance which is what I believe 99% of car owners who modify their cars with performance parts are looking for.
it is always easy to talk smack on the board. what a dick.
IMHO I think Daytona would benefit from the exhaust even more in his road race superstar racing. It’s ridiculous to compare peak gains on a dyno to decide what performance you will pick up. Road racing will put him in higher RPMs 90% of the time and honestly those are the areas where a free flowing exhaust will shine.
For someone who thinks he knows a ton of things about road courses…tires, suspension…performance gains should be just as important. The 1/4 mile is really only an acceleration tool to compare performance it’s not the end all be all like most people think AR is about, but it shows a hell of a lot more than a dyno if your only focused on the peak hp/TQ numbers.
I think the forum would benefit from hearing Daytona tell us his impression of the epl tune since only him and I believe rs4power and one other guy have it that we know of.
Rs4power was one of the crusaders for custom tuning who died on his sword on that topic even after the forums let him know that custom tuning for catback was not even remotely necessary. The other guy was the epl test car, so neither of them are likely to give much of an impartial review…
That leaves Daytona. So…?
I must admit that you do often offer hours of amusement but it certainly takes sifting through 80% of your bullshit to find the 20% of value you add here and there. Someone simply questions something and you turn it into an attack bc I don’t have the same exact ideas as you. I did not buy a Milltek clown, it came with my car. I’m sure with the hours of internet searching you do all day that’s something you could have easily figured out. I have not seen any data that says dp’s alone will add x acceleration, which is simply all that many reasonable minded people look for. The delta from specific mod’s whether ur using 1/4, acceleration, or dyno’s. There has been nothing that I’ve seen to compare the varying individual component gains.
And no euro, I’m not only focused on peak numbers. The area under the curve is what will often determine real world performance. But I’m sure you already knew that and just wanted to pile onto Bob’s bandwagon so I’ll let that go. Delta through the power band is essentially what acceleration tests will show anyway.
Your latest beauty…while advocating reviewing dyno sheets vs. standardized acceleration tests, you said
‘The area under the curve is what will often determine real world performance’
So you would prefer to look at a dyno to tell you what the real world performance will be…instead of just testing real world performance!!!
As for measuring performance of just a downpipe, the stock tuning parameters don’t take full advantage of just slapping on a downpipe mod without a tune that has the range to beiinefficientficientit from the flow. A good tune with parameters that can take advantage of your modlist as it grows is necessary. In this case 1+1 = more than 2. Measuring what 1 part does on it’s own is really rather supernumerary.
Anyway, why not show the forum about something you do know, which is the EPL tune.
So once again, where is the acceleration data for adding dp’s alone? I already explained a couple posts ago that the net gain for all components would be greater than the individual component gains. Sometimes I wonder if you just choose not to read before you comment or if reading in general is an area of difficulty for you.
I guess maybe I’m crazy for thinking this, but it’d be pretty nice to see something like
stock= x acceleration from 3-8k rpm
dp’s=x acceleration
dp’s+cat-back= x acceleration
dp’s+cat-back+tune= x acceleration
Sorry but downpipe only data makes no sense. Why would you add 2.75" downpipes to a smaller catback whether it be stock or milltek? and waste the time testing that combo? If anything I could see guys buying the catback and doing piggies like they do on the S4, then upgrading to DPs later on.
In your case you mention $3k, but it seems like your only interested in DPs and you did compare peak numbers when you were commenting on $3k for 10-15whp.
What is you plan? To buy DPs alone mated to a Smaller diameter milltek catback? Why not buy full JHM system for $2750, sell your milltek (that was free to you) for a decent amount to recoup some of the cash and have a nice setup that is the best on the market? If you find away to argue that suggestion then I don’t know what your really looking for besides arguments.
Did EBwerks put out DP only data? Or just full system data?
