Hi All. Owner of the RS4 with the AMD S/C base kit checking in.

[QUOTE]OK - my car is done. 100% final setup with the AMD Base Kit install.

Base kit = baby kit = Stage .9 = Low Pressure Kit (I’ll leave it to Jason to confirm actual/final name). It is the first of 3 stages that will eventually all be available. The next two are in development, and sorry for the tease, but - - there is plenty more ‘go’ coming. I witnessed it myself today!

What did I pay for the kit and what comes with it?
All hardware and software, installed at AMD for $10,750. I believe if you install elsewhere, you’d need to add install (12-14 hours?). Kit uses the TVS1900 blower, runs a 115mm pulley, and boost is around 9-10 psi. Note: this base kit does NOT upgrade any fuel pumps, and does NOT add any additional cooling / radiators over stock. The next stages from AMD include both upgraded fuel pumps and cooling.

What’s included with software aside from more go? Launch control and flat shift. :slight_smile:

Why did I chose AMD? For me, I evaluated the following criteria 1) Value ($/whp gained), 2) Ease of entry (financial), 3) Future upgrade potential without ripping everything out, and 4) Local tuner.

For me here in the US, it was really between the APR kit and this one, and AMD won out because of my criteria. The $/whp gained comparison, goes as follows: at the time I looked, and still today, APR kit is advertised at $15k. I’ve heard you can get install included, but it doesn’t say so anywhere. Still - giving the benefit of the doubt, let’s say it’s included. Looking at the site and dyno chart here, you look to gain 126whp over stock with their kit on 93 octane (we get 92 in Seattle). That’s $15k/126 = $119/whp gain. From day 1 of talking with AMD, it was clear the base kit would get around 100-120whp. I knew this going in. So, let’s be conservative again and say 100. $10,750/100 = $107.50/whp gain. Criteria 2-4 were also all in favor of AMD, and in the end probably a bit more important to me than this first one. (Note: actual $/whp gained turns out to be $94/whp for the base kit). Please also note: I give full props to APR. Seems like they have a great product with proven results. It just didn’t fit my criteria as well as AMD’s offering. Peace.

Dyno details: chart is from AMD dyno (Mustang), all corrected numbers. You see 3 runs which reflects the history of my car: stock, then with DP’s and software, then the S/C results. I still run my stock catback, btw, so likely leaving a little bit on the table. I took it to a local shop that uses a Dynojet also to see differences. This was before we were done with the tune. At the time, we were hitting ~385whp on the Mustang (corrected) vs the 414 we ended up with. At the Dynojet, it read ~410whp corrected at the time. So - a delta of 25whp. At any rate - - for those who want to gauge the neighborhood of power the products are in - - you can probably add 25whp to the results I got on the Mustang, to equate to Dynojet results? 414+25 = 439. As my stock corrected read 282, and APR’s results show the more commonly referenced 312 (30whp difference), that kind of makes sense to me. Whatever…not sure it’s worth doing that comparison, better to focus on whp gained, IMO.

The 414 represented above was one of 4 runs. Others were 408, 416, 417.

Where’s the 1/4 mile result??? Sorry, haven’t been there. I’d like to see how it does, and I’m sure will get the chance in the coming months. I know many are dying to see those numbers. You get 2 chances a month here basically to hit the strip, and my schedule is not cooperating.

What’s it like to drive? Instant power, that never goes away until you shift. It’s a completely different car. On top of that, drivability is perfect. You can be smooth and quiet and put around town if you’re so inclined or just hammer it and get instant response. Super happy with my results :slight_smile:

Anyway - there you have it. I think I’ve included everything :wink:
I’m happy to answer any questions if you have them.

Cheers,
Per

Axel has already started the war in AZ lol.
He has a very good point that AMD supercharger for RS4 makes the same power as the JHM sc for the s4.
Which JHM stg1 sc is maxed out for stock internals plus under tuned to keep it reliable. But the AMD maxed out the power in their sc before the internals are even close to their limits.
Can’t wait for JHM sc to come out just to put these guys to shame.

Is it the blower, or is it the tuning? It doesn’t make sense that size of blower can’t produce.

Never mind that the jhm kit is what… 6 psi? And the amd kit is 10 lol

Dyno to dyno is kinda useless, but amd foolishly chose the dyno as their 'proof '. Well that’s not true… They took the car to the dragstrip and it flopped. So they’re instead doing this bullshit with their customer doing the sneaky marketing on a forum where they can’t advertise.

I guess we can’t forget the race video they posted of the high boost kit racing a 13 second 370z…or the other video of the low boost kit where it raced a stockish rs4 and put the same gap as a jhm tune and bolt ons car.

Here’s the side by side comparison in case anyone missed it.

https://www.youtube.com/watch?v=Cz8lO2aLwXs

I noticed on another forum comparisons were made between our kit and the AMD kit using only peak figures, so I responded with this:

Here are our numbers vs AMD’s numbers. I’ve also included the gain over each companies stock figures. Our stock figures do not show a large jump around 5500 RPM like AMDs, so the delta before that point is much higher all things considered.

If we want to discuss % for creating a comparison between our two dyno’s differences in reporting stock figures, it’s not a flat percentage at all. It our dyno reads higher torque in the lower RPM range and much closer to AMD’s numbers in the higher RPM range.

Here’s a raw comparison of horsepower, stock an modified from each company. The gain charts indicate they make nearly identical HP over stock towards redline.

http://www.goapr.com/news/wp-content/uploads/2013/04/compare.jpg

is it just me…or does it look like EPL couldn’t deal with the stock torque limiter (throttle limiter)?

I wonder if we could get RS4per to log throttle valve angle in group 003 for us lol

That’s very interesting. That Blue delta line is all over the map. Almost as inconsistent as Mick’s lies about his quarter mile times.

To the ignorantly uneducated that graph reads “AMD and APR are about equal”

To the educated enthusiast it reads “AMD are a bunch of lying thieves”

I think that on a power basis, they are pretty equal. Within 25 whp either way, depending on how good or bad one’s dyno numbers are.

People are forgetting the facts real equick.

1. APR dyno’d with stock 2.50-2.36" downpipes with 4 catalytic converters and 2.36" catback, ; AMD had 3" downpipes and no catsWhen JHM showed their 12.40 @ 111 quarter mile run 2 years ago, all of quattroworld went APE SHIT because it was a catless exhaust, thus was not representative of reality blah blah blah…and that a huge amount of the gain is from the cats deleted. Nobody said SHIT when AMD posted this catless dyno vs. stock with 4 cats.

2. AMD is using a TVS 1900 blower that is 44% LARGER THAN THE APR BLOWER! (TVS1320)

3. APR went 11.8 @ 119: This AMD kit hasn’t shown shit. However the big boost $15,000 version did…and it went low fucking 12s.

4. the AMD kit put 3 car lengths on a stock Rs4. So did a tune/exhaust RS4 put 3 car lengths on my 12.75 @ 108 RS4. The APR kit put 3 buslengths on a sorted stage III B5 S4 lol.

This AMD kit is so far turning out to be a fucking disaster. When you have a beta tester selling the kit on the forums, and losers like Mickf29 coming out of RS4 retirement to support the kit, you know it is a shitshow.

BOTTOM LINE - if you’re buying a fucking TVS1900 kit, you don’t think your dyno charts are going to line up favourably with a TVS1320 kit!

Arin way to pop in and set the record stright…this amd shit is a joke…from how they are handling all tbisonline and there aattempts to use you guys as the hentch mark. … the bad part is they d8djt sven grt it right when they tried to get over on you…

This is the ‘% gain over stock’ showing AMD vs. APR

What this proves is that the stock AMD dyno run was fucked up in the early RPMs. It’s kind of funny that nobody sees this. They are turning this into ‘LOOK HOW MUCH TORQUE WAS GAINED!’ when reality is they should be screaming ‘Yuck…that’s some bad data we’re using’

Notice that in the go zone, from 6000-8000 RPM, in otherwords where you will be when you’re accelerating hard, be that via pbox or highway pull or 1/4 mile, they are identical.

That’s a fucking PR disaster for AMD. Don’t the fanboys realise this???

https://lh5.googleusercontent.com/-ZqjTRd-nAX0/UX_ASRM86HI/AAAAAAAAKdM/Hp26yPZFy0E/s1024/AMDvsAPR_4782_image001.gif

Yeah, it’s screwed up. The AMD car dyno’d way lower than a normal RS4, especially with the mods it had yet the. 6k+ rpm gain is identical to APR’s lol.

Well that’s what happens to all of these guys. Stockholm Syndrome

They have their money kidnapped, then empathize with the tuner because they can’t stand to be wrong.

I love the B5 S4 guys jumping into every AMD thread to tell everyone with an RS4 what’s what. lol.

The AMD marketing team is pretty funny. Most recent revelation? These kits are NOT ready for the market yet. They are still working on them.

The RS4per guy is the only 0.9 kit and the woodi guy is the only 1.0 kit. Both are beta testers. Both kits, AMD/Aviva and their various marketing committee members have said a few times the kit is done

Then they go and dyno, only to take it back and say ‘CAN’T RELEASE RESULTS…STILL WORKING ON IT!’

Then they go make a bunch of changes…and then take it the strip for the glory pass. Time to show JHM what’s what in 4.2 land, right? We’ll take the big boost 15 PSI car…the big fuelling upgraded car…the one with the massive cooling upgrades…the one with the FULL catless exhaust…and we’ll drive it ourselves so the client can’t fuck up our marketing.

Then they run 12s

Then it’s BACK TO THE DYNO FOR MORE TESTING! and…‘THE AMD KIT IS MODULAR AND CAN BE UPGRADED!’

lolz…last time I checked that was the hail mary setup and it fucking flopped.

So is this the bottom line: this amd car is predicted to be no faster than mistro or axel’s cars?

It must be the lightweight nature of the cars we have here.

How would it be a disaster if the AMD kit makes much more power on the low end? Even if the 6-8k power is similiar the race in the all mighty 1/4 is already over by 6k rpm. The whole benefit of forced induction is having more power throughout the power band whereas the NA only makes real power in the 6-8k range. So to discount the power in the 2-6k range seems pretty silly, but maybe that’s just me.

Dude you just made no sense…1/4 mile is over by 6k…lol
Go do some AWD burnout for 5 sec in the waterbox…your a fuck

I did need a laugh after a long day of work though…thanks

Go away…

Are you stupid? If the 6-8k power is the same and the AMD has more on the bottom end the race is over. Thanks for you wise comments.

OK guys, let’s give Larry a chance to show us what he knows. We’ll pretend he’s a new user.

Explain to me what you meant just now. This whole ‘the AMD has more bottom end the race is over’. We’ll pretend the AMD does have more bottom end (it doesn’t…that chart is actually showing delta over stock, and the AMD car dyno’d artificiallly low in stock form, but that’s beside the point).

So…if car A has a 10% ‘bottom end’ advantage from 0-6000 RPM…but is identical to car B from 6000-8000, please explain how in a race from 0 to 1320 feet, it’s ‘over’ for car B?

+1.
Bahahahhahahahaha

I said it’s a disaster if the TVSr1900 kit is making APR TVSr1320 power from 6000-8000. It means something went wrong. The delta from the 1900 will not be the low end. It will be the high end. The RS4 motor revs to 8200 RPMs. To feed it and fill it with a 1320 you’re going to run out of steam. To give it a 1900 it’s a whole new level of power. Or it should be…if you know what you’re doing. There should be pretty amazing delta from 6000-8000. There isn’t though. Something’s not right. I have a couple of ideas. I also think it’s funny tha tthey wanted to run a TVSr2300. Clearly they haven’t been thinking this through.

They dyno’d it at AMD a few times till they got a nice chart (it was 385 whp before!). Then they dyno;d it on a dynojet and made around 410 whp. They were hoping for 450 whp on the low pressure kit. That’s just not that good. The APR cars dyno from 400-430 whp (I’ve seen 3 or 4 RS4 APR 1320 cars).

If you slap a massive blower on a car, you’re not guaranteed a result. Look at the supercharged R8 kit from Stasis. What blower does it use on the R8 4.2? How about their R8 5.2 kit? They’re fucking slow for what they should be. It’s pretty straightforward…this 4.2 is a tiny V8. The only smaller one I’ve seen with any similarity is the M3 motor. None of these guys we’re talking about have used a big TVS blower on a tiny V8 that revs to 8000+ RPMs. This is uncharted water. I’m not even talking about the tuning. As we’ve learned, EPL tuning hasn’t exactly been a home run on ANY Audi, let alone on a 4.2 Audi. Last time I checked, you’re not happy with your EPL tune and wanted to make a switch. Yes? So you may know all about that.

Untimately the success of the kit will be based on what can ultimately be pulled out of the system. There’s a possibility that without the additional cooling of the bigger kit that maybe the APR system did max out what could be zone on stock fueling etc. How long did it take APR to wind up with a tune that took the kit to the next level. So if the .9 is about the same as the APR kit in current form for 20% lower retail price it’s not a failure. If the 1.0 kit ends up being priced where the APR kit is and has 50+whp more, then it’s a success whether someone wants to hate on them or not. You all just seemed really excited to shoot something down before there’s even sufficient data to support the succes of a kit one way or another. Just makes no sense. Even if the 1.0 is already at low 12s with minimal testing that’s substantially better than where PES ever ended up so how about just relaxing for a minute and see how things develop. Should someone buy a .9 now with the minial data out, no. But creating all the conspiracy theories as though u have concrete info about a kit makes just as little sense to an objective viewer. You guys have way to much time to go arguing back and forth over whats actually been released. This kit was labeled a failure by all of you before any data even came out. Just comical.
