APR B7 RS4 Stage III TVS1740 Supercharger System breaks into the 10's!

B6/7 S4/RS4

Oh, you came from BMWs…now we get it.

This isn’t Saki’s forum #1, and he doesn’t ever pretend to know anything…go ahead, fact check him. #2 If you understood why he was ever banned from the other forums, you’d probably like the guy. He holds companies and bullshitters accountable…IMO if you sit back and watch while people get scammed or fed bullshit, your just as guilty as them, but Saki would be the first to say something.

Notice how there isn’t any riff raft around AR? Because they can’t deal with people who are true enthusiasts and have a clue what they are talking about.

Plenty of kudos was given to APR, some of us just like to know more details than other that like to stare at dynos

Great thread with great info!

RT/Ernie, please don’t get dissuaded from sharing more information. The nice thing with Audi Revolution is that they’re unrelenting when it comes to pursuing data. For better or worse (depends on perspective).

Please pardon my limited/non-existent tuning no how (I’m not an engineer but I do work with data):
I’ve always wondered how the 4.2 V8 would handle boost (since I do plan on slapping this on the RS5 - as soon as I have the funds available - lol @ other hobbies and prepping the RS5 for track season next year). The supercharged 3.0 V6T in the B8 S4 had an actual boost sensor that we could pull from Vag Com (it also has a MAF sensor). So we could look at actual boost and compare it against requested boost on the B8 S4 and some members here have done a great job logging those values (primetime, pete, and tsivas).

But for a NA car, I was curious if a boost sensor would be included and it would have a requested vs actual boost, but it looks like it all keys off of Mass Airflow. I should probably start logging my car and getting familiar with the values in it’s stock form.

Here you go. 11.12 @ 125.7 w. 1.69 60’

Density Altitude was around +200 to +300 feet (323 feet 28 minutes earlier at 7:53 pm, the nearest reading on dragttimes)

Some key things you may want to know…

  1. JHM SC kit at 8 lbs of boost (strangely they knew what it was without us asking)
  2. Air to water Intercooled
  3. JHM 5r clutch kit (you know what this is…seems you needed it to make the APR kit work)
  4. JHM 93 octane tune for Stage 2 SC (you know what this is too?)
  5. JHM full exhaust, catless - 2.75" downpipes + 2.75" x-pipe catback
  6. STOCK fuel pumps
  7. STREET tires
  8. PUMP gas
  9. FULL interior

^^ Saki just a heads up I think you posted APRs slip

#78

That’s JHM’s slip. Now. :slight_smile: Thanks for the note.
Interesting that both cars MPH’d 100 at the 1/8. Shows how the limits of the stock fuelling held the JHM car back so much in the big gears where the car was running out of fuel so they had to hold it back in the tune. Also shows how the slicks help the car rocket through the first half. APR car had 1 tenth on JHM at 60’, 2 tenths at 330 feet, 4 tenths at 660 feet. Picked up only one more tenth in the second half which is weird considering they picked up 30 MPH vs JHM’s 25.

Going to be very interesting here soon. I wouldn’t be shocked to see JHM go 10s @ 130 on pump gas, full interior, street tires. Which is what APR did with race gas, no interior, no exhaust and slicks. The ET comes down to the launch. That 1.50 is a huge difference maker, knocking 2 tenths off 1/4 mile ET right away and about another tenth from the 1-2 through 70 mph. Without those tires, that car is running 10.75-10.80 or so on race gas (104 file), with no interior and no exhaust. Close up the yard sale and put the parts back on the car and I wonder what it would do. 10.90 or so with a GREAT launch? It went 11.07 @ 129 with race gas, full interior and with an exhaust. That had a weak launch though. Give APR a 1.70 60’ and they have a 10.95 @ 129.

1: Can someone comment on the statements from numerous sources (close to the owner of this car) claiming that this car is in fact running much more than 8psi?

2: Can someone also explain why the car has been diagnosed with cylinder 4 failure aka blown up engine?

I’m just trying to clarify I believe these are both true.

Side note.

hahaha Jason, you’re too much. I can clarify some things for you. I know the owner.

In California, it went 11.12 on 8 PSI with the JHM stage 2 kit with intercooler. Also had various LW parts like JHM rotors, flywheel etc. They sent it back to him in late spring, and towards the end of the summer, he asked for more boost. They (in Michigan) put on a smaller pulley, upgraded fuel pumps (it was stock fuelling when it went 11.12) tested it, and everything went great. Then it went to Milan and snapped a half shaft on the first pass. That was a few weeks ago. Milan closed shortly thereafter and unfortunately the car didn’t get back to the track. Engine was fine. Clutch and PP was fine. Unfortunately the axle broke, so what can you do. I was standing there at Milan when this happened. I have a video of it on youtube.

The owner has decided he wants to go stage 3 built motor. Should be one of the first few to get this done, and hopefully he will have it in the spring when he gets back to driving his RS4. The RS4 has become a bit of a project car for him, not a daily driver. His other cars are…impressive.

I should add…when we went to Milan (about ten people) the RS4 was only making about 9.5 PSI with the smaller pulley. It wasn’t drastic. ‘Much more’ is a bit of a laugh. To make sure you don’t act a fool, the smaller pulley was installed in Detroit, along with the fuel pumps, in September.

#81

Engine isn’t fine dude. I was just at the dealership that diagnosed it. Funny how a piston isn’t a blown up engine but a head gasket is. I asked them why the car came in. They told me it had fuel leaks, the blower had blown gaskets and was leaking (not sure it was oil or boost leak) and cylinder 4 had 0 psi on compression.

I love Kevin but your lies stop here.

#82

If this is truly the ‘keep the real’ forum you should be honest. The engine is blown up.

The purveyor of truth shouldn’t be the front-man of perpetuating the lies.

#83

I shouldn’t even say but. You know what I love about Kevin, he doesn’t lie about stuff.

Side note.
#84

I can.

1 The car set every pump gas record with nothing more then 8lbs of boost

2 It wasn’t cylinder 4 and it appears to be a bad injector

#85

Actually the motor is fine. The funny thing is sakimano saw the car driving, did you?

None of what your making up is true. I would be happy to have kevin sign up for the site to tell everyone how you are making stuff up to try to make JHM look bad.

The fuel line at the distribution block leaked, dealer fixed it. The blower has no real gaskets, so add this to the list of stuff your making up. The blower is filled with oil, any excess is then allowed to purge out as not needed. Try to educate yourself about Vortech blowers and their fill procedure before you take others words for it.

#86

I’ve had many injectors go bad and never completely lost a cylinder - and I’ve seen hydro-locked engines from bad injectors that still make compression and your car has ZERO.

Can you explain what “93 octane on a 91 octane tune” means? Is that just adding race gas in with some pump left and calling it pump gas?

Can you also explain why a car with the same ‘claimed’ set-up went to the track and barely could run 11’s on your 11.1 set-up?

#87

I don’t own a RS4, so I don’t know how my car would have zero. The car was compression tested by me and it never had zero compression on any cylinder. I can see your desperately looking to try and make this look good for you and bad for JHM. It might be best that your attempt to make this look bad stops before it gets turned back to show the poor nature on how this is founded.

Taking second hand information and running with it isn’t always a good idea.

#88

You’re a weird dude. I’m a member of the site and saw your post, so I replied to it. Is that ok? I told you what I know about the car. Everything was fine when I saw it, and the owner is going stage 3 now. If there’s an injector problem or whatever else, I’m not his mechanic.

The car was running great when I saw it the last weekend of September before the half shaft issue on the launch, and it’s on its way to be built for stage 3.

You’re even weirder. I have lied about NOTHING. I told Jason what I know about the Grey car. Clearly you are playing a game of telephone with someone from an Audi dealership. From the sounds of it, you haven’t spoken to Kevin, who for some reason you love.

#89

Guys, I’m just attempting to apply the same standard to everyone equally. You have made ‘truth’ out of things that you hear about AMD that are not true - but you actually even further twist them into what you want on top of that and then systematically perpetuate the false narrative.

Look at Per’s engine pull - you made the guy go and actually have to post his invoice from the dealer online proving why his engine was pulled and that it was actually partially covered UNDER WARRANTY from an existing job!! Yet the war machine perpetuates that there was an engine problem.

These things should be equal across the board. They are not. THAT ENGINE IS BLOWN UP. This is just the reality.

#90

My point is not to derail the thread the for APR and honestly their amazing achievement. My point is bring light to the fact that the car that the war machine is using to derail this thread is not what they say it is - and furthermore - is blown up!!

Congrats APR - we may have something for you ;D

#91

Jason,

Your issues don’t lie with JHM. supporters of JHM are just that, none of the JHM supporters speak for JHM. So, if your issue is with JHM then we can take that to task. If your issues are with others, I would suggest you take that with them. Attacking JHM because you don’t like the supporters of JHM seems to me, ill directed.

This is the second time you have attempted to “attack” JHM if you will. If you’re indeed excited with the thought that the JHM supercharger has or had blown a customers motor don’t worry. While JHM won’t blow a customers motor i’m sure they will be more then happy to destroy their own.

#92

To show what a poor sport you are and how you run your business. I can have the owner of the car, sign up for the site and then have JHM drive his car on video to show just how you do things and how you are the worst of what your accusing others of. I think it will be great poetic justice on how you really are.

#93

Kurt seriously enough of your B.S. I’m not attacking anyone I’m providing information, and let’s be honest this entire site is honed in on attacking me not only from a business perspective but a personal perspective. On top of that you also like to obtain peoples personal mobile phone numbers so you can attack and physically threaten them directly with calls and texts. You have told people to ‘tell me’ how you’re going to kill me and how dangerous you are. This is all very professional and I applaud you.

The house will fall Kurt. These are not lies.
